An intraocular lens for implanting in a human eye, comprising:
- a) a lens optic defined by opposite anterior and posterior surfaces and a peripheral wall having a peripheral edge thickness “PET”, the juncture of said posterior surface and said peripheral wall defining a sharp edge;
- and
- b) at least one haptic attached to and extending from said peripheral wall, said at least one haptic having a haptic thickness“HT” and adapted to apply a biasing force against said optic in the direction of said posterior optic surface upon implanting said intraocular lens in said human eye, the juncture of said haptic and said peripheral wall defining a posterior optic thickness “OTp” and an anterior optic thickness “OTa” on either side of said haptic, and wherein said posterior optic thickness “OTp” is more than half of said peripheral edge thickness “PET”.
