Intraocular lens centration with continuous tear capsulotomy.

This study was designed to determine whether continuous tear capsulotomy was associated with improved posterior chamber lens centration. Two hundred eyes were divided into two subgroups of 100 patients each. In one subgroup a standard can-opener capsulotomy was performed and in the other, a continuous tear capsulotomy. All other factors including the cataract extraction technique, intraocular lens (IOL) style, the capsular bag placement of the IOL, and the use of viscoelastic material were constant. In this study, IOLs implanted after a continuous tear capsulotomy were found to center more reliably than IOLs implanted after a can-opener capsulotomy (P less than .01).
