EFFECT OF ANTERIOR CAPSULOTOMY ON DECENTRATION OF A 2-ZONE MULTIFOCALINTRAOCULAR-LENS

A study was undertaken to determine if can-opener (CO) or continuous c urvilinear capsulorhexis (CCC) anterior lens capsulotomy influences de centration of a two-zone multifocal intraocular lens (lOL). Fifty lOLs (25 with polypropylene haptics and 25 with poty[methyl methacrylate] haptics) were implanted following CO, 42 with poly(methyl methacrylate ) haptics, following CCC. The extent and direction of decentration was estimated using a photogeometric technique. The haptic material may i nfluence decentration. Continuous curvilinear capsulorhexis was associ ated with less decentration than CO (0.36 mm and 0.43 mm, respectively ). The difference, however, was not statistically significant.
