A Case of Thick Anterior Capsule of Hypermature Cataract in Down Syndrome

Purpose: We report a case of severe thickening of the anterior capsule in a case of hypermature cataract with Down syndrome. Methods: A 30-year-old woman with Down syndrome underwent intracapsular phacoemulsification followed by in-the-bag implantation of an intraocular lens (IOL) under general anesthesia. Pathologic examination was performed. The anterior capsule was then incised at the 12 o`clock position by intraocular scissors because continuous curvilinear capsulorhexis (CCC) was too difficult given the thickened anterior capsule. Intracapsular phacoemulsification was followed by in-the-bag implantation of IOL and the incised anterior capsule was trimmed. Results: Pathologic findings of the extracted anterior capsule documented a thickening of the anterior capsule 20-fold over that of a normal anterior capsule as well as depositions of fibroblasts and collagen materials. Six months after the operation, the patient`s visual acuity was 0.3 and no complication was found.
