Abstract
An intraocular lens having an optic region and an anchor plate attached to the optic region and extending radially outwardly therefrom at diametrically opposite ends of the optic regions, and a pair of resilient haptic loop members attached to the anchor plate and displaced thereby from the optic region.
Claims16
An intraocular lens comprising:
- a disc-shaped central optic member;
- a haptic anchor plate attached to said optic member in essentially co-planar relationship therewith, said haptic anchor plate having a width essentially equal to the diameter of said optic member and a length greater than the diameter of said optic member so that said anchor plate extends radially outwardly from said optic member at opposite ends thereof, the length of said haptic anchor plate corresponding to the transverse dimension of the capsule bag in the eye of the recipient into which the lens is intended to be inserted to hold the lens in said capsular bag, and said haptic anchor plate being sufficiently rigid to resist deformation when fibrosis of the capsular bag occurs;
- and a pair of arcuate resilient haptic members attached to said anchor plate at opposite ends thereof to be compressed down adjacent to the end edges of the haptic anchor plate when the lens is positioned in the capsular bag of the eye of the recipient, and to spring outwardly from the ends of the haptic anchor plate when the lens is positioned in the sulcus of the eye of the recipient for positioning said intraocular lens in the sulcus.
An intraocular lens comprising:
- an optic portion;
- a haptic anchor plate extending radially outwardly from said optic portion at diametrically opposite ends thereof and attached thereto, said haptic anchor plate having a length corresponding to the transverse dimension of the capsular bag of the eye of the recipient into which the lens is intended to be inserted to hold the lens in said capsular bag, and said haptic plate being sufficiently rigid to resist deformation when fibrosis of the capsular bag occurs;
- and a pair arcuate resilient haptic members attached to said anchor plate at opposite ends thereof to be compressed down adjacent to the end edges of the haptic anchor plate when the lens is positioned in the capsular bag of the eye of the recipient, and to spring outwardly from the ends of the haptic anchor plate when the lens is positioned in the sulcus of the eye of the recipient for positioning said intraocular lens in said sulcus.
The intraocular lens defined in 8, in which each of said haptic members is attached at both ends to said anchor plate.
