Outcomes of cataract surgery in eyes with weak zonules
Reviewed by Eulee Seow

Pseudoexfoliation (PEX) and zonular weakness have long been known to increase the risk of complication of cataract surgery. This retrospective study looks at the results of phacoemulsion and intraocular implantation in 295 eyes with pseudoexfoliation and zonular weakness, with a mean follow-up of 4.08 years (max 8.1 years). While vision, IOP and glaucoma medication requirements were similar postoperatively, postoperative complication rates are higher in PEX eyes with preoperative and / or intraoperative signs of zonular weakness undergoing phacoemulsification. It was also found that nonsutured capsular tension ring (CTR) implantation does not prevent IOL and capsular complications postoperatively, which may be worth bearing in mind when faced with managing a patient with zonular weakness undergoing cataract surgery.
