ABSTRACT:
An intraocular lens for use as an artificial lens impant in the posterior chamber of the human eye adjacent the posterior capsule, after extracapsular extraction is disclosed. The intraocular lens includes an optical lens body, and a continuous ring-like member spaced from the rear surface of the lens body by a plurality of supporting bosses which are attached to and extend directly rewardly from a peripheral portion of the rear surface of the lens body. The continuous ring-like member is preferably made of PROLENE.RTM. and forms a resilient seal against the posterior capsule of the eye when implanted in the posterior capsule, thereby extending the period of time between cataract extraction and subsequent corrective micro-surgery necessitated by secondary cataract growth.
