ABSTRACT:
An intraocular (IOL) assembly for implanting in the posterior chamber of a human eye after an extracapsular extraction is disclosed. The IOL assembly includes an optic holder having haptic elements for locating and positioning the optic holder in fixed position within the posterior chamber of the eye and an optic lens releasably secured to the optic holder for interchange of different optic lens as needed, without removing the entire optic holder from the eye. Haptic elements include flexible and resilient haptic elements with reversely curving free ends for implanting the optic holder within the posterior chamber. For releasably securing the optic lens to the optic holder, several different mechanical and/or adhesive constructions or techniques may be employed. When it is desired to change an optic lens, it is a simple matter to releasably remove the optic lens from the optic holder and replace the removed optic lens with the new optic lens desired by also releasably securing the same in position relative to the optic holder.
