Abstract
An intraocular lens for inhibiting posterior capsular opacification, or secondary cataract, includes an optic having a periphery provided with a sharp, flexible flange which presses against the posterior capsule wall thereby creating a barrier to LEC migration.
Claims11
An intraocular lens for implanting in a human eye, comprising:
- a) a lens optic having opposite anterior and posterior surfaces defined by an optic periphery;
- and
- b) a flexible flange formed adjacent to and radially outwardly of said optic periphery, said flange having a posterior surface which engages the posterior capsule wall when said IOL is implanted in the eye, said flange further including a flange apex which extends radially outward of said optic and acts as a barrier to prevent lens epithelial cell migration between said posterior surface of said optic and the posterior capsule wall of the eye.
An intraocular lens for implanting in a human eye, comprising:
- a) a lens optic having opposite anterior and posterior surfaces surrounded by an optic periphery;
- and
- b) a flexible flange formed adjacent to and extending radially outwardly of said optic periphery, said flange having a posterior surface which engages the posterior capsule wall when said IOL is implanted in the eye, said flange further including a flange apex which extends in a direction away from said optic, said flange having an arcuate shaped cross-section, said flange acting as a barrier to prevent lens epithelial cell migration between said posterior surface of said optic and the posterior capsule wall of the eye.
An intraocular lens for implanting in a human eye, comprising:
- a) a lens optic having opposite anterior and posterior surfaces surrounded by an optic periphery;
- and
- b) a flexible flange formed adjacent to and extending radially outwardly of said optic periphery, said flange having a posterior surface which engages the posterior capsule wall when said IOL is implanted in the eye, said flange tapering from said optic periphery and terminating in a flange apex which extends in a direction away from said optic, said flange acting as a barrier to prevent lens epithelial cell migration between said posterior surface of said optic and the posterior capsule wall of the eye when said intraocular lens is implanted in the eye.
