LOW PROFILE INTRAOCULAR LENSES

摘要

A refractive intraocular lens (24) including an optic portion (34) having an outer peripheral edge (36) and two or more but preferably two, three or four equally spaced haptic elements (38). Each haptic element is of like fluidly varying trapezoidal form to achieve a "propeller-like" appearance. Each haptic element is also manufactured to have an inner portion (40) with a gusset (44) and an outer portion (42) with a contact button (46) for supporting the optic portion in a patient's eye. The inner portion (40) of each haptic element is permanently connected to the outer peripheral edge (36) of the optic portion. Each haptic is formed to have a relatively low profile and a greater resistance to bending in a plane generally parallel to an eye's optical axis (OA-OA) than in a plane generally perpendicular to the eye's optical axis. The intraocular lens is so designed to exhibit less than approximately 1.0 mm axial displacement of the optic portion along the eye's optical axis under a compression force suitable to effect a 1.0 mm in diameter compression of the intraocular lens.
