Perforation rosette of the lens after Nd:YAG laser iridotomy.

Abstract

To describe an unreported complication of Nd:YAG laser iridotomy. We examined a 31-year-old patient with pigment dispersion syndrome and moderately increased intraocular pressure whose left eye had been treated prophylactically with Nd:YAG laser iridotomy and who complained of blurred vision thereafter. Slit-lamp examination of the left eye disclosed a typical perforation rosette of the posterior pole of the crystalline lens with a perforation of the anterior lens capsule under the iridotomy site and pigment within the lens. Opacity regressed spontaneously, and vision returned to normal. A perforation rosette of the lens can occur after Nd:YAG laser iridotomy and should be considered a possible serious complication of the procedure.
