Intraocular lens optic capture

Abstract

A continuous curvilinear capsulorhexis (CCC) provides a tear-resistant opening that allows use of a technique of capturing the intraocular lens (IOL) optic through the capsulorhexis opening when the opening is at least 1.0 to 2.0 mm smaller than the optic diameter. The technique provides stability and long-term centration of the IOL and prevents vitreous from extending anterior to the IOL. This paper reviews the current variations of optic capture including (1) haptics in the sulcus and IOL optic capture through a CCC, (2) haptics in the sulcus and IOL optic capture through an anterior capsule opening and a posterior CCC (PCCC), (3) haptics in the capsular bag and IOL optic capture through a PCCC, (4) haptics in the capsular bag and IOL optic capture through an anterior CCC, (5) haptics in the sulcus and IOL capture through a capsular membrane opening, and (6) haptics posterior to the capsular bag and IOL capture through a capsular membrane opening. © 2004 ASCRS and ESCRS.
