AIM:To discuss the clinical features of capsular block syndrome after cataract phacoemulsification and intraocular lens implantation and Nd:YAG laser treatment options. METHODS:Retrospective analysis was conducted on the clinical features of 7 cases of postoperative capsular block syndrome and Nd:YAG laser treatment.2 cases of early postoperative capsular block syndrome used Nd: YAG laser peripheral anterior capsulotomy; 4 cases of late postoperative capsular block syndrome with only posterior capsular opacification and thickening used Nd:YAG laser posterior capsular resection; 1 case of late capsular block syndrome associated with fibrous membrane proliferation on optic zone of anterior and posterior intraocular lenses surface used posterior capsular re-resection after Nd:YAG laser anterior and posterior capsular resection of intraocular lens. RESULTS:Seven cases after Nd: YAG laser treatment restored good vision, no serious complications occurred. CONCLUSION: To take a corresponding Nd: YAG laser treatment is safe and effective according to clinical features of postoperative capsular block syndrome.
