title: Effect of anterior capsulotomy on decentration of a two-zone multifocal intraocular lens.
abstract: A study was undertaken to determine if can-opener (CO) or continuous curvilinear capsulorhexis (CCC) anterior lens capsulotomy influences decentration of a two-zone multifocal intraocular lens (IOL). Fifty IOLs (25 with polypropylene haptics and 25 with poly[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 influence decentration. Continuous curvilinear capsulorhexis was associated with less decentration than CO (0.36 mm and 0.43 mm, respectively). The difference, however, was not statistically significant.
