ABSTRACT:
The invention contemplates improved intraocular-lens structures for use as implants in ophthalmological surgery, the lens being a replacement for a cataract-clouded natural lens, and the replacement being installed through the pupil at the iris as the operative step following removal of the cataracted lens. The lens features adapter structure assembled to an optically finished lens element and including plural angularly spaced stabilizing feet which are formed integrally with the body of the adapter and which are axially offset from the adapter body to permit the stabilizing feet and the adapter body to engage features of the eye within the posterior chamber.
