Definitions
- the present invention relates generally to technology and business solutions directed to the correction of ophthalmic defects.
- the invention describes systems, instructions, and methods directed to providing a predictive outcome for therapeutic ophthalmic correction of vision disorders.
- the invention is intended to provide a higher degree of patient vision quality resulting from vision correction procedures.
- myopia and hyperopia are the result of a lower-order optical aberration called defocus.
- Simple astigmatism is also a lower- order aberration. Briefly, a perfectly myopic eye brings all incoming parallel light to a focal point in front of the retina; a perfectly hyperopic eye brings all incoming parallel light to a focal point behind the retina; and a simply astigmatic eye focuses some of the light in a horizontal line and some of the light in a vertical line at some separation distances from the retina.
- RK is a surgical procedure designed to correct nearsightedness by flattening the cornea with a series of incisions that resemble the spokes of a wheel.
- Roberts reports changes in anterior corneal geometry due merely to the keratectomy (flap cut) prior to laser ablation.
- the biomechanical corneal response to an invasive stimulus such as a keratectomy prior to LASIK or the severing of corneal lamellae by the laser in a PRK procedure can be explained, according to Roberts, by conceiving the cornea not as a piece of plastic, but rather as a series of stacked rubber bands (lamellae) with sponges between each layer (interlamellar spaces filled with extracellular matrix).
- the rubber bands are hypothesized to be in tension, since there is intraocular pressure pushing on them from underneath, and the ends are held tightly by the limbus.
- each sponge depends upon how each rubber band is stretched. Greater tension squeezes more water out of the sponges so the interlamellar spacing decreases; i.e., the cornea gets flatter. Thus the act of laser surgery itself to reshape the cornea may alter the corneal bio-structure with the effect that what you see is not what you get.
- U.S. Patent Application Publication 2002/0103479A1 to Sarver discusses optimizing the predictability of a vision correction method using surgical outcomes in an iterative analysis to create an optimized treatment outcome.
- the inventors have recognized a need for hardware, software, and methods that will facilitate optimum outcomes of therapeutic ophthalmic procedures, in particular, photoablative refractive vision correction and, alternatively, customized ophthalmic optics, that result in optimum vision quality and greater patient satisfaction.
- the instant invention is directed to apparatus and methods that enable predictive outcomes for proposed therapeutic ophthalmic corrections including photoablative refractive surgical procedures and customized ophthalmic optics, and which support a transactional model for providing the predictive outcomes.
- Reviews of numerous clinical studies to date indicate that no single or simple combination of factors appear to explain the differences between calculated or desired photoablative refractive outcomes and actual outcomes, nor are they outcome predictive. In other words, there is no assurance that the surgical procedure/technique or the ablation algorithm that is used to treat today's myopic patient will produce the same outcome if used on tomorrow's similarly myopic patient.
- An interesting observation that has been made, however, is that consistency and standardization in all aspects of photoablative refractive surgery produces better therapeutic (corrective) outcomes.
- the embodiments of the invention involve the use of optimized theoretical and historical, outcome-determinative data to generate a best predictive instruction (e.g., optical zone size, keratectomy depth, an ablation algorithm for driving a therapeutic laser, etc.) for the practitioner's use to optimize the outcome of a proposed vision defect correction.
- a best predictive instruction e.g., optical zone size, keratectomy depth, an ablation algorithm for driving a therapeutic laser, etc.
- These parameters might include, for example, patient profile information (e.g., refraction, biographical, cultural, etc.), practitioner technique (nomograms, historical outcome data, etc.), equipment specifications (e.g., laser make, model and operating parameters, software version, principle of diagnostic examination, etc.), the diagnostic procedure (e.g., aberrometry, elevation based topography, ultrasound, OTC, etc.), the ambient environment conditions (e.g., temperature, humidity, time, etc.), and other factors not listed nor so limited.
- the computer program can analyze this historical input data to determine, for example, the statistically significant parameters and their relationships to past therapeutic outcome success. For today's patient #1001 with a known myopic defect, the surgeon can enter into the computer, by manual or automatic means, new, prospectively relevant parameters.
- the computer can analyze this information in light of the optimized theoretical and historical information that it has access to, and generate an outcome-predictive instruction, such as a customized laser ablation shot profile algorithm, for example, for driving a therapeutic laser system, that is predictive of an optimized outcome for correction of the measured defect.
- an outcome-predictive instruction such as a customized laser ablation shot profile algorithm, for example, for driving a therapeutic laser system, that is predictive of an optimized outcome for correction of the measured defect.
- an embodiment of the invention is directed to a system that provides a predictive outcome for a proposed therapeutic ophthalmic correction that includes a collecting and transmitting station (or platform) for receiving a plurality of prospective therapeutic-outcome-influencing information (pre-operative data in the non- limiting case of photoablative surgery) relating at least to either a patient and/or a practitioner and/or a diagnostic measurement and/or a therapeutic condition, and/or an environmental condition, and for transmitting the plurality of information to a computing station.
- a collecting and transmitting station or platform for receiving a plurality of prospective therapeutic-outcome-influencing information (pre-operative data in the non- limiting case of photoablative surgery) relating at least to either a patient and/or a practitioner and/or a diagnostic measurement and/or a therapeutic condition, and/or an environmental condition, and for transmitting the plurality of information to a computing station.
- the computing station can receive the plurality of information, store a plurality of historical, therapeutic-outcome information that has been derived from an optimization analysis of theoretical and historical, prospective therapeutic-outcome-influencing information relating at least to either a patient and/or a practitioner and/or a diagnostic measurement, and/or a therapeutic condition, theoretical treatment plan, actual outcomes data, and/or an environmental condition, and then provide an analyzed output that is a best predictive instruction for obtaining an improved therapeutic ophthalmic correction.
- the collecting and transmitting station could be a computer station that is interfaced by hardware and/or software means to any of a variety of diagnostic devices (e.g., wavefront sensor, topographer, pachymeter, tonometer, etc.), to a therapeutic system (e.g., excimer laser, custom ophthalmic lens platform, etc.), to an operating room "weather station,” and/or that provides means for practitioner input of other prospectively relevant new data.
- diagnostic devices e.g., wavefront sensor, topographer, pachymeter, tonometer, etc.
- a therapeutic system e.g., excimer laser, custom ophthalmic lens platform, etc.
- the computing station could be part of a local, inter-office system or, alternatively, it could be a remote server on a network, and/or internet based. Transmissions to and from the computing station could be facilitated by any waveguide-based or wireless means, or by portable media such as a CD or disk. An advantageous routing medium would be secure internet transmission.
- the software and data structure for performing the optimization analysis of the theoretical and actual historical therapeutic-outcomes and the analyses of the new information for generating and providing the best predictive instruction can take various approaches.
- Preferred, but non-limiting examples include statistical analysis (e.g., multiple linear regression), multidimensional vector (matrix) analysis, neural networking, and finite element analysis (FEA).
- Databases may be composed of, e.g., individual practitioner data, FDA clinical data, pooled third party results with real-time updating, manufacturers' clinical data, etc.
- Computer stations, network servers, diagnostic devices, therapeutic devices, and interface hardware and software do not in and of themselves constitute parts of the invention er se as they are all independently available components.
- an embodiment of the invention is directed to an executable instruction, embodied in a deliverable means to an end user-controlled device, that can be used to provide a predictive outcome for a therapeutic ophthalmic correction.
- the invention is directed to an ophthalmic diagnostic and/or treatment system including diagnostic and/or treatment components, and a graphical user interface (GUI) having a display and a selection device that facilitates the selection of collected information for analysis with optimized historical information provided in or by a data structure, and resulting in an outcome-predictive instruction for a proposed vision correction procedure.
- GUI graphical user interface
- Another embodiment according to the invention describes a method for providing a predictive outcome for a proposed therapeutic ophthalmic correction.
- the method includes the steps of collecting a plurality of therapeutic-outcome-influencing, "new" information including at least ophthalmic defect information about a patient; providing this new information to a computing platform that contains a data structure including optimized, theoretical and actual historical, therapeutic-outcome information for the determined ophthalmic defect; and generating, via the computing platform, a best predictive instruction for a proposed corrective treatment of the determined ophthalmic defect based upon an analyses of the new therapeutic-outcome-influencing information in conjunction with the historical outcome information.
- a preferred aspect of this embodiment describes a method for providing a predictive outcome on a fee or transactional basis as a business model.

- the outcome is effected preferably by a customized LASIK treatment to correct lower-order and higher-order aberrations that cause vision defects in the patient's eye 120, or a custom retreatment for a decentered ablation, for example.
- LASIK a customized LASIK treatment
- the capture, feedback, and analysis of data does not restrict the invention merely to LASIK; rather, the strategy and implementation of the invention will apply to PRK and LASEK, for example, as well as to the design and performance of custom ophthalmic optics including contact lenses,
- a collecting and transmitting station 102 is shown in the form of a wavefront sensor.
- the wavefront sensor 102 measures the preoperative optical aberrations of the patient's eye 120, preferably up to the fifth, and in some cases the seventh, Zernike order, or equivalent.
- An exemplary wavefront sensor which is not in and of itself a part of the invention er se, is described in Williams et al. U.S. Pat. No. 5,111,119, the contents of which are herein incorporated by reference in their entirety to the extent allowed by applicable patent laws and rules.
- Manifest refraction of the patient's eye can also be obtained from the wavefront sensor data as described, for example, in commonly owned pending U.S.
- Manifest refraction data and higher-order aberration data represent a subset of prospective therapeutic-outcome-influencing information 105 relating to the patient.
- the arrows 104 represent other prospective therapeutic-outcome-influencing data relating, for example, to the practitioner, other diagnostic measurements, therapeutic conditions, and/or environmental conditions.
- the doctor may wish to input personal nomogram information and past outcome data for similar vision defects as currently measured, as well as the make, model, and operating principle information about the wavefront sensor and the laser (therapeutic device) that will be used to correct the patient's vision defect, operating room ambient conditions, or any other information that could prospectively influence the results of the customized photoablative surgery.
- the practitioner may want to optimize post-surgical spherical (and others) aberration to improve low-light vision quality and, therefore, would include preoperative spherical aberration as a specific input parameter.
- All of this information 105 (104) is manually or automatically input to, or collected by, the collecting and transmitting platform 102, and transmitted as shown at 103 as "new" information to a computing station 110.
- Transmission 103 can occur by known means including, but not limited to, directly, via the internet, telephonic data transmission, wireless communication, via CD, disk, etc.
- the computing station 110 can be located locally, in the doctor's suite, for example, or remotely. In any case, the computing station may be capable of receiving new or historical input from other sources as indicated by the arrows 106, and described in more detail below.
- the computing station 110 preferably operates in three functional capacities. One of these capacities is to receive "new," prospective therapeutic-outcome-influencing information 105 as described above.
- the computing station includes a storage medium, e.g., disk space, and an appropriate data structure (described below), that contains and/or can generate optimized theoretical and actual historical, therapeutic-outcome information 112.
- This historical information has been derived from optimization analyses of actual historical data, prospective therapeutic-outcome- influencing information, and theoretical surgical plans relating to patients, practitioners, diagnostics, therapeutics, environmental conditions, and so on. For example, a practitioner may have performed 1000 prior LASIK procedures.
- Each procedure to correct a patient's measured vision defects involved a particular diagnostic measurement obtained with the aid of a particular diagnostic device, a specific laser system with an ablation profile-driving algorithm possibly modified by the surgeon's personal nomogram, and a particular keratectomy procedure for flap creation (LASIK).
- Each patient had a profile indicating age, race, gender, etc.
- Ambient operating room conditions provided an environment in which each procedure was performed.
- each therapeutic procedure was characterized by an outcome (post-operative results over measured follow-up periods) that was knowingly or prospectively influenced by some or all of the foregoing variables, and perhaps others.
- outcome predictive therapeutic relationships can be determined.
- the computing station 110 can operate in its third
- This best predictive instruction preferably is a customized algorithm used to drive the photoablative equipment and procedure, but may include other optimized information relevant to the procedure, such as, e.g., LASIK flap thickness and/or optical zone size.
- the approach for generating the best predictive instruction 116 according to the invention include various preferred embodiments.
- a first embodiment utilizes multiple linear regression, for example, to provide a statistical analysis of the actual and
- Figure 5 shows the distribution of what are referred to herein as higher-order aberrations (3 rd , 4 th and 5 th order Zernike) among 92 preoperative eyes from a clinical study sample group.
- 3 rd order aberrations (Z 3xy ) represent the majority of preoperative wavefront aberrations in the normal population, with (negative) spherical aberration (Z 4 oo) also being significant.
- Z 3xy represent the majority of preoperative wavefront aberrations in the normal population, with (negative) spherical aberration (Z 4 oo) also being significant.
- LASIK treatment is the inducement of higher-order aberrations, particularly spherical aberration, which may account for reduced vision quality under low light conditions.
- Figure 6 shows measured (RMS) higher-order aberrations preoperatively and at three
- Planoscan refers to a conventional (defocus, astigmatism) LASIK treatment algorithm
- Figure 7 is a graph similar to that of Figure 6 except that the spherical aberration term (Z oo) has been removed in order to show the contribution only by the other 3 rd , 4 th and 5 th order Zernike terms.
- a stepwise multiple linear regression was performed using all preoperative 3 rd and 4 th order Zernike coefficients to investigate the predictive nature of the relationship between postoperative spherical aberration and preoperative measures; specifically, to predict the three-month spherical aberration (Z oo) for the Zyoptix and Planoscan treated eyes at three different pupil sizes, 5.0mm, 6.0mm, 7.0mm.
- Z oo three-month spherical aberration
- Figure 8 shows for the 6.0mm pupil, there is strong agreement between the observed and predicted values using this equation.
- a multi-variable matrix approach could be used to provide the best predictive instruction.
- the current procedure for determining an ablation profile based upon a thin lens formula is limited by various shortcomings. For instance, biodynamics and healing response are not considered, and simple use of the Munnerlyn formula leads to a tissue removal profile based only on refractive power changes. Moreover, the current linear approach does not adjust for individual procedure differences among surgeons. What results from all of this is refractive power adjustment through personalized nomograms without viable means to effect aberration correction adjustment.

- Update information could be obtained from multiple sources through a variety of acquisition schemes including purchase or lease of the relevant information.
- a neural networking environment 2000 is an approach that could provide the best predictive instruction to the surgeon.
- Neural networking sometimes referred to as neuro-computing, is a fundamentally new approach to information processing, and is the first viable alternative to sequential programmed computing.
- Neural networks offer distinct advantages for applications where there is little or no existing knowledge of how to develop an algorithm. Neural networks can operate where there is imprecise or ambiguous data, and can be trained to produce reliable predictions from historical information.
- a neural network can adapt to external input by modifying memorized data according to specific learning laws. These in turn may re-size the shape of the network (number of connections) as it maps the problem.
- the task of improving refractive surgical outcomes can be viewed as the analysis of a large and varied set of patient, diagnostic and historical data and the prediction of ablation algorithms that give the desired outcome. Since much of the data provided for determining ablation algorithms has proven to be difficult to analyze and determine correlation coefficients by traditional statistical methods, neural computing may prove to be an ideal tool for analyzing a broad base of diagnostic data and providing optimized, predictable outcomes.
- the neural network may function in a back-propagation mode as follows in Figure 11, which illustrates a simple neural computing model 2000 involving data based training.
- the hidden layer 2003 may consist of the historical information (rules and relationships) that would be proprietary to a third party, which allows the system to test and learn from existing data and outcomes. Knowing historical outcomes from past procedures, the hidden (analysis) layer 2003 is trained to perform appropriate calculations to achieve desired outcomes by pre-assigning known weighting factors to generate intermediate outcomes. As new patient data, theoretical outcome data, and actual outcome data become available, the hidden layer 2003 continues to be trained to output a best predictive instruction at the output buffer 2005.
- the unique property of neural networks is that they can be trained from an existing set of data and known solutions to update the hidden layer weighting functions and rules to improve outcomes from future information.
- the neural computing model would preferably be implemented on web-based application models 3000, 4000 as shown in Figures 12 and 13, respectively. All information 3002, 3004 would be collected at a computing site 3006 where data analysis could be completed and predictive best-instruction output 3008 returned to the client 3010. Input and output would preferably be through a web-based application that interfaces with a computing architecture 4000 shown in Figure 13.
- the rules box 4001 refers to the necessary computer software and analysis techniques to complete the process.
- the storage requirements 4003 also could be defined. Once the system was defined it could be expanded easily to support a client base of any size. This represents a standard scalable architecture for web-based businesses.
- a fourth approach embodied by the invention relies on a probabilistic finite element analysis (FEA) using accurate corneal ultra structural model (CUSM) input and a correct finite element in conjunction with new input data as described above to obtain Young's Modulus data and Poisson's Ratio information about the eye. It has been proposed that a proper biodynamic model of the eye must include both a structural modeling of the cornea provided by an ultra structural fiber model and a fluid dynamic analysis based upon a hydrated matrix model component.
- CUSM Cornea Ultra Structural Model
- Biologic tissues when examined on a macroscopic scale, appear non-isotropic and highly nonlinear.
- tensile tests that measure this behavior do not reproduce a valid physiologic environment. For example, elongating strips of corneal material at first produces no measurable tension, but instead, a release of water. Eventually, often at hyper-physiologic conditions, tension rises exponentially over a limited range.
- These complex nonlinearities may, however, be the result of ignoring mechanisms that are for the most part linear, but complexly intertwined. Nevertheless, as a linear composite of linear mechanisms retains its linearity, there must be some essential nonlinearity. Ideally, this nonlinearity is fundamentally simple, and is magnified by the complexity of the overall, mostly linear, mechanism. If this is the case, an accurately predictive and widely applicable model will only be realized after the essentials of all ultra-structural mechanisms are fully incorporated.
- the cornea is a complex composite material consisting of oriented fibers (lamellae) 10002, as shown diagrammatically in Figure 14, primarily arranged in layers, spaced by a hydrophilic matrix of glycosaminoglycans (GAGs), and filled with water, some bound and some free.
- GAGs glycosaminoglycans
- IOP Intraocular pressure
- Increasing peripheral opacity of the cornea, especially near the limbus, is indicative of less fibril organization (e.g., an increase in fibril crossings) near the limbus.
- Fibril spacing is maintained by a complex balance between springy spacing materials (the interfibril GAGs) and fluid pressure (which at homeostasis is relatively negative, about -60 mmHg).
- the negative pressure or suction (imbibition) is maintained by the endothelium.
- corneal thickness is proportional to hydration.
- Excised stroma in saline expands up to 150 percent its physiologic value on a time scale of hours. When constrained in saline, a substantial positive swelling pressure can be measured. When suction is applied to counteract the swelling pressure, a negative imbibition pressure can be measured.
- Inter- fibril cross-links, the matrix composition, the fibril layer structure, and fibril orientation are all spatially dependent within the cornea. Local fiber layer orientation is at least partially responsible for observed non-uniform meridional strains induced by excess intraocular pressure.
- the cornea is flaccid in youth, becoming more rigid with age. This is presumably due to increased cross-linking and/or stiffening (through accumulation of various molecular species) of the inter- fibril matrix with age.
- fibers are theoretically defined as compact groups of fibrils.
- the fiber is a modeling construct rather than physiologic entity. It is a way of subdividing a physiologic layer.
- the corneal fiber model follows from three postulates:
- Fiber area is conserved. The number of discrete fibrils and fibril spacing is conserved. Therefore, as a fiber is defined by the distinct fibrils it contains, fiber area must be conserved.
- the limbal plane 10020 is a plane that best fits the limbus.
- the corneal apex 10022 is the central anterior surface point farthest from the limbal plane.
- the corneal axis 10004 is the normal to the limbal plane that intersects the corneal apex.
- Meridional planes 10006 n contain the corneal axis.
- the central fiber in any layer is the one that intersects the corneal axis. Layer fibers farthest from the central fiber are lateral fibers.
- the medial plane is the meridional plane that perpendicularly intersects the central fiber.
- Fiber aspect ratio changes gradually from medial to peripheral locations. If the area of a fiber is conserved and if fibers always follow geodesies, then a fiber laid over a convex surface must be thinnest medially, increasing peripherally. This explains in part why stromal thickness increases peripherally. However, the inventors postulate that the observed increase in thickness is not fully explained by individual fiber aspect changes. To reproduce the normal human thickness distribution, different fibers in the same layer must have different areas, the area increasing from the central to lateral fibers. 2. Lateral fibers blend naturally into the limbal circumferential fiber ring. Geodesic orientation causes lateral fibers to bend towards the periphery. The most lateral fibers therefore flow easily into the limbal fiber ring.
- Corneal organization leads to scleral disorganization (crossing). Tiling fibers in a single layer follow geodesies that over a sphere would cause all the fibrils to cross at two opposing diametrical points. Taking this spherical example a step further, the multiplicity of overlaying layers crossing at all angles together contain fibrils that all cross at the equator, the locus of the crossing diametrical points. Topologically this means that the uniform tiling over the cornea necessarily leads to extensive fibril crossing in the annular limbal region.
- Fibers do not follow geodesies outside the cornea.
- Limbal ring fibers for example, do not follow geodesies.
- the parallel lay of corneal fibers does not permit lateral fiber-bending forces. Hence corneal fibers must follow geodesies. Scleral fibers, being interwoven, can exert lateral forces on one another and follow non-geodesic curves.
- Corneal fibrils are conserved. This can be deduced from the repeated observation that fibrils do not seem to end but appear to span the cornea from limbus to limbus (and beyond). If fibril ends are infrequent or terminate in some confluence with another fiber, they would be very difficult to detect. Fibril conservation may not be rigorously correct as it is difficult to envision how any unending fibril could be constructed. Hydrated Matrix Model
- Corneal fibers are bent by an internal pressure gradient set up by the intraocular pressure. For example, if the layer surface were spherical, then the pressure gradient normal to the surface would be given by
- the glycosaminoglycan matrix which maintains the inter-fibril spacing, is very hydrophilic. Imbibed water causes the matrix to expand, and thus fibril spacing is governed by controlling corneal hydration.
- the physiologically normal state is relatively dehydrated, which requires a negative internal pressure for homeostasis.
- the mechanical picture of the matrix is one of a springy material under compression brought about by relatively negative hydraulic pressure.
- the "spring constant" of the matrix can be deduced from measurements of the imbibition or swelling pressure.
- Imbibition is the negative hydraulic pressure within the matrix.
- “Swelling” is the positive reaction pressure of the compressed matrix. The measured form of the positive swelling pressure,
- Hydration is defined as the water mass divided by the dry mass of the cornea (both fibrils and matrix).
- the swelling pressure relation above is valid over H ranging from 1 to 10. It has been observed that corneal thickness, T, is linearly related to hydration, dT/dH equaling 0.14 mm/H for human corneas.
- the dry mass density of the cornea, po is substantially the same for all mammalian
- the schematic in FIG. 16 shows the normal static hydraulic pressure profile in the human eye from exterior to interior.
- atmospheric pressure in the air 10030 there is a negative jump of about 60 Torr to the imbibition pressure 10032. This rapid drop is impressed across the epithelium.
- Over the corneal stroma 10034 there is a gradual pressure increase, equaling the IOP in total.
- Across the endothehum 10036 there is a positive jump to the IOP, which is uniform in the anterior chamber 10038.
- This homeostatic picture will be altered by surgery and other interventions.
- a study [Odenthal, 1999] examining the effects of a two-hour hypoxic stress noted an overshoot in corneal thickness followed by an exponential relaxation indicative of a damped oscillation.
- finite element model will incorporate what is currently believed by the inventors to be the essential components taken from the CUSM, consisting of (a) fibril orientation; (b) lamellar size and structure; (c) lamellar mechanical properties; (d) hydration transport mechanisms; (e) stromal structure; (f) epithelium; (g) hydrophilic GAG's structure; (h) crosslinking between lamellar layers; and (i) fibril structure at the limbus (circumferential ring).
- FEM finite element model
- the individual data considered necessary for constructing the correct finite element consists of (a) topographic elevation data; (b) wavefront data; and (c) IOP data.
- a correct finite element can be constructed.
- the finite element will be a three-dimensional, anisotropic, layered, solid element having 20 nodes.
- an invasive procedure can be simulated and the modeling results compared with empirical data from actual surgical outcomes.
- the finite element can then be iteratively modified until simulated procedures match observed responses.
- the output of the optimized model then provides a best predictive instruction for a proposed surgical ophthalmic correction.
- a cornea simulation model 500 shown in Fig. 17 includes the sclera 502, limbus 504, and cornea 506, where corneal anterior/posterior surfaces in the optic zone were determined from diagnostic examinations made with an Orbscan corneal analysis system (Bausch & Lomb Inc., Rochester, New York). The sclera, limbus, and peripheral regions of the cornea are assumed to form an elliptical shape which transitions to the measured cornea surfaces at the edge of the optic zone.
- Fig. 18 shows a cut-away finite element mesh 508 of the corneal model.
- orthotropic layered brick elements 510 are used to represent all regions of the eye, where the material properties and material orientations for each layer 512 n serve to define the gross properties of each region.
- the layer properties are uniform and give rise to a transversely isotropic response, while the lamella in the limbus have a dominant circumferential orientation and high hoop stiffness.
- the cornea lamellae have random orientations near the posterior surface, and transition to more predominantly orthogonal orientations near the anterior surface. These orientations are illustrated by the five layered elements 512 ⁇ -512s shown by the element representation 550 in Fig. 20.
- each finite element layer (maximum of 100 layers per element, with 5-10 elements through the cornea thickness) must be specified as either a) epithelium, b) Bowman's layer, c) lamella, d) ground substance, e) Decemet's Membrane, or f) endothehum with a prescribed orientation and structure. Truncated normal distributions are used to sample the layer thicknesses as well as the lamella width and orientations; a bilinear weighting function is used to modify the lamellae orientations as a function of depth below the anterior surface. In regions where a simulated lamella would coincide with previously defined lamella, that portion of the layered element is assumed to consist of ground substance.
- the lamellae are assumed to extend from limbus to limbus along meridians, with thickness variations consistent with constant cross sectional area.
- the parameters of the sampling distributions can be chosen to represent a broad range of assumptions regarding lamella geometry and the layered lamella interactions.
- the element formulation incorporates a stress stiffening effect to account for internal pressure.
- Nonlinear geometrical effects are also included in the evaluation of the finite element response.
- incisions between finite elements can be simulated by releasing the connectivity between elements that are adjacent to an incision surface. This is accomplished by defining duplicate nodes along potential incision surfaces, and mathematically tying them together. The actual incision is then simulated by releasing the ties sequentially. An example of decoupling the elements is illustrated in Fig. 21.
- the finite element analysis approach involves the inclusion of all of the structural properties and observed behaviors of the human cornea combined with additional data on the structure of the human eye. Combining this information with specific information from a patient, the structural observations are then incorporated into a 3D model of a patient's eye.
- the equation contains all of the information necessary to predict the mechanical behavior of the human cornea.
- the equation may become nonlinear, in which case the mathematics become more complicated.
- the actual solution of these equations will require the solution of a system of non-linear partial differential equations (PDE's).
- PDE's non-linear partial differential equations
- the differential equations will be solved by finding a solution to the weak form of the PDE's. It will be appreciated, however, that the mathematics required to solve the corneal problem are identical to the mathematics to solve any material deformation problem.
- the embodiment of the invention is the constitutive relationships which are dependent upon the constitutive properties that are created inside of elements and between elements. If one knows the constitutive properties of the elements, a solution can be found for the corneal response system.
- This instant embodiment is designed to back calculate corneal constitutive properties for classes of patients and provide predictive analysis of the cornea structural response due to any action asserted upon the cornea.
- sclera elliptical shape parameters are specified. These parameters can be obtained from axial length measurements of the eye, or generalized values from the normal population may be used.
- patient cornea geometry is determined. Preferably, this is anterior chamber geometry and most preferably, this is in the form of non-uniform rational basis splines (NURBS) obtained with an Orbscan pre-treatment examination. In alternative aspects, appropriate data could be obtained by OCT or C-scan (ultrasound) measurements.
- NURBS non-uniform rational basis splines
- appropriate data could be obtained by OCT or C-scan (ultrasound) measurements.
- a 3D solid geometry of the entire globe including cornea, limbus and sclera is formulated (as illustrated in Figs. 17, 18.
- step 608 the incision/ablation surfaces are identified based upon a best estimate of a prospective surgical plan. Applanation of the cornea is simulated with applanation plate 514 of Fig. 17, and a 1mm deformed cornea is illustrated in cut-away and enlarged in Figs. 23 and 24, respectively.
- step 610 default finite element size is selected and a finite element mesh is generated as illustrated in Fig. 18. A spherical element coordinate system is used, and the element edges coincide with the incision/ablation surfaces. In essence, the elements are built around the intended incisions with the ability to couple and de-couple the elements at those locations.
- the element layers are defined. The process for each layer is as follows:
- (c) Specify lamella locations and orientations for this layer, by i) selecting a starting point on circumference (0 to 360 degrees), ii) selecting a lamella orientation (-90 to 90 degrees; function of depth), iii) selecting lamella width (1 to 4 mm), iv) projecting each lamella from limbus-to-limbus; v) if clear or partially blocked by another lamella in this layer, reduce width and complete projection; otherwise, define as ground substance vi) have maximum number of lamellae been processed? IfNo - go to (c);
- the boundary conditions are defined. These preferably include a displacement constraint at the sclera, and individualized IOP values.
- the basic material parameters of the system are specified. These include Young's moduli (E x , E y> E z ); Poisson's Ratio (v xy , v yz , v xz ); and shear moduli (G xy , G yz , G xz ).
- the incision ablation surfaces are released and an incremental non-linear solution is performed.
- the modeled corneal shape is compared with measured post-treatment data. If the shapes are in agreement, then the finite element is modeled correctly. If the shape agreement is not satisfactory, then the method returns to step 616 where the material parameters are modified and steps 618, 620 are reiterated.
- the end result of the modeling is an accurate finite element model for each "class" of patients that can then be used as predictive information when a new patient in a particular patient class is evaluated for surgery, according to the invention.
