INTRAOCULAR LENSES

摘要

A refractive intraocular lens (32) including an optic portion (34) having an outer peripheral (36) edge and two opposed looped haptic elements (38). Each looped haptic element (38) is formed to have two broad connecting portions (40), two radial orientation portions (42), two spring portions (44) and a linking portion (46) for supporting the optic portion (34) in a patient's eye (10). The two broad connecting portions (40) of each looped haptic element (38) is permanently connected to the outer peripheral edge (36) of the optic portion (34). Each looped haptic element (38) is likewise formed to have greater resistance to bending in a plane generally parallel to an eye's optical axis than in a plane generally perpendicular to the eye's optical axis. The intraocular lens (32) is so designed to exhibit less than approximately 1.0 mm axial displacement or tilting of the optic portion (34) along the eye's optical axis under a compression force suitable to effect a 1.0 mm in diameter compression in overall length of the intraocular lens (32).
