Intraocular Lens

Abstract

An IOL having an optic and a peripheral stabilizing ring. The optic and the ring are connected by a flexible bridge. An area on the ring coinciding with a feature on the optic helps to locate the optic within the ring in an unstressed state until the capsular bag collapses and locks the optic into place.

1 . An intraocular lens, comprising:
 a) a support ring;   b) an optic connected on one side by a bridge;   c) a tab located on the optic opposite the bridge; and   d) a locating feature on the support ring, the locating future cooperating with the tab so as to center the optic within the support ring in an unstressed state.   
     
     
         2 . The lens of  claim 1  wherein the locating feature comprises a channel with a slot. 
     
     
         3 . The lens of  claim 1  wherein the locating feature comprises bumps or protuberances projecting inwardly from the support ring and toward the optic. 
     
     
         4 . The lens of  claim 1  wherein the locating feature comprises a ledge and a locking ridge. 
     
     
         5 . The lens of  claim 1  wherein the locating feature comprises a ledge having a slot, the locating feature projecting inwardly from the support ring and toward the optic. 
     
     
         6 . The lens of  claim 1  wherein the locating feature comprises a channel having an open slot, the channel projecting inwardly from the support ring and toward the optic. 
     
     
         7 . An intraocular lens, comprising:
 a) a support ring;   b) an optic connected on one side by a bridge;   c) a tab located on the support ring opposite the bridge; and   d) a locating feature on the optic, the locating future cooperating with the tab so as to center the optic within the support ring in an unstressed state.   
     
     
         8 . The lens of  claim 7  wherein the locating feature comprises bumps or protuberances projecting inwardly from the optic ring and toward the support ring.
