[Evaluation of capsular block syndrome with an anterior segment OCT].

A year after routine phacoemulsification and insertion of a soft posterior chamber IOL, a 59-year-old woman developed progressive moderate myopia. A syndrome of late capsular block was diagnosed following biomicroscopic examination, which was treated by Nd YAG laser posterior capsulotomy. The myopia disappeared immediately. This observation was illustrated with optical coherence tomography (OCT) developed for the anterior segment. After capsulotomy, the IOL moved backwards by 448 microm, which corresponds exactly to a--1D induced myopia.
