Assessment of capsular block syndrome with anterior segment optical coherence tomography

A 59-year-old woman developed progressive, moderate myopia 1 year after routine phacoemulsification and insertion of a soft posterior chamber intraocular lens (IOL). After biomicroscopy, late capsular block was diagnosed and treated with a neodymium:YAG laser posterior capsulotomy. The myopia disappeared immediately. This case was illustrated using optical coherence tomography developed for the anterior segment. After capsulotomy, the IOL moved backward by 448 microm, corresponding to -0.75 diopter of induced myopia.
