Abstract

The invention provides a disposable plastic mold assembly (10) for an intraocular lens or the optic body thereof, which is inexpensive, less labor intensive than prior art intraocular lens molding techniques, and produces an intraocular lens having smooth, polished edges which require little or no post-mold finishing work. Numerous innovative features of the invention include an edge design which assures a seal between the male (12) and female (14) molds to thereby minimize flash during the cast molding operation, and the provision of a means for pre-aligning the male and female molds during assembly, consisting of an interference fitting relationship between the male and female molds. An additional feature is a means for maintaining contact between the male and female molds during casting, which particularly involves the provision of a negative draft angle on the inner surface of the female mold's outer wall, or, alternatively, texturing which is applied to that inner surface so that it engages the outer edge at the top of the male mold during assembly. Yet another important feature of the invention is a means for achieving axial and rotational orientation to produce lens edge geometries without unwanted steps on the lens edge. The alignment is achieved with interlocking steps (34, 36, 38) on the male and female molds. The interlocking elements may be pins or annular elements.
