Fibrotic cataract as a sign of posterior capsule violation post vitrectomy

Abstract

Purpose: To report fibrotic cataract as a sign of posterior capsule violation post vitrectomy. Observations: A 16 year old female presented to our retina clinic after multiple prior vitrectomies at an outside hospital for traumatic retinal detachment. On presentation, it was noted that she still had a silicone oil inside the eye, and a dense, fibrotic cataract limiting the posterior pole view. The decision was made to pursue cataract phacoemulsification plus silicone oil removal. We utilized the Zepto capsulotomy system given the white cataract. After gentle bimanual irrigation and aspiration of the cataract, it was discovered there were two small, round, posterior capsule defects with fibrosis around these holes that extended anteriorly, involving the capsular fornix and anterior capsule. This was confirmed intraoperatively on heads-up OCT. A three-piece intraocular lens was placed into the capsular bag, but given the contracted capsular fornix, the IOL was decentered inferonasally, so it was repositioned in the sulcus with good centration. Conclusions: It is known that pars plana vitrectomy leads to accelerated cataract formation postoperatively. This case report is the first to our knowledge that describes a fibrotic cataract as a sign of posterior capsular violation. Importance: We demonstrate that presence of fibrotic cataract post vitrectomy should raise suspicion for capsular violation and should prompt further discussion with the patient regarding appropriate surgical planning and expectations.
