PURPOSE: To review the clinical characteristics and surgical outcomes of patients with true exfoliation syndrome of the lens capsule having phacoemulsification cataract surgery. SETTING: Hong Kong Eye Hospital, Kowloon, Hong Kong. DESIGN: Case series. METHODS: Eyes of patients with true exfoliation syndrome diagnosed clinically or intraoperatively had standard phacoemulsification and intraocular lens (IOL) implantation. The anterior capsules removed during capsulorhexis were sent for histological confirmation. RESULTS: Twenty-four eyes of 18 patients were included. All eyes were confirmed to have true exfoliation syndrome by histological examination of the anterior lens capsule. Seven eyes (29.2%) had preexisting chronic glaucoma; 5 (20.8%) had laser iridotomy before the diagnosis. During phacoemulsification, all eyes had a continuous curvilinear capsulorhexis without complications. Trypan blue staining was used during capsulorhexis in 11 eyes (45.8%). Posterior capsule rupture occurred during lens chopping in 1 eye (4.2%). No loose zonular fibers or radial extension of capsulorhexis occurred. Capsular bag IOL implantation was successfully performed in all cases except the 1 with a posterior capsule rupture, in which an anterior chamber IOL was implanted. CONCLUSIONS: Phacoemulsification was safely performed in eyes with true exfoliation syndrome. Trypan blue staining can be used to facilitate capsulorhexis creation. Ultrasound biomicroscopy or anterior segment optical coherence tomography may be useful in preoperative assessment of such cases. The disease may be associated with glaucoma and laser iridotomy.
