title: Effect of the laser ridge on posterior capsule opacification.
abstract: The most common complication of extracapsular cataract extraction is posterior capsule opacification, which appears to result from the proliferation of anterior lens epithelium onto the posterior capsule. The presence of a posterior chamber intraocular lens has been shown to decrease the incidence of posterior capsule opacification, possibly by a barrier mechanism. This retrospective clinical study compares the effect of two different lens designs (with and without a laser ridge) on posterior capsule opacification requiring Nd:YAG laser posterior capsulotomy. Twenty-one of 101 patients (20.8%) with nonridged lenses required Nd:YAG laser posterior capsulotomies versus 13 of 86 patients (15.1%) with ridged lenses. Although these data showed a clinical benefit from using a ridged lens, no statistical difference in the incidence of posterior capsulotomy was noted. Further evaluation of capsular-optic surface apposition is needed.
