Abstract
An intraocular lens for implantation within an eye after cataract surgery, etc. The intraocular lens has a free-ended, compressible, sizing prong, which sizing prong in its natural uncompressed state has a preformed closed coil spring section between its ends. This intraocular lens with its sizing prong is particularly suited for implantation within the posterior chamber behind the iris where the sizing prong is outwardly biased against the ciliary sulcus area of the eye to hold the intraocular lens in proper viewing position.
