Abstract

BACKGROUND Pseudoexfoliation (PEX) is a systemic microfibrillopathy characterised by accumulation of gray-white fibrogranular extracellular material over the lens, pupil or cornea. Different clinical variants of PEX in cataract patients are known to occur. We wanted to study the different clinical variants of PEX in cataract patients, the intraoperative and postoperative complications and the visual prognosis of cataract surgery. METHODS A total of 100 patients with PEX in cataract were subjected to detailed examination and necessary investigations. Cataract surgery was performed in all patients using the manual small incision cataract surgery (SICS). Vision before and after surgery was recorded. Refraction was done and documented. Best corrected visual acuity was noted and was followed-up postoperatively for 2 – 4 weeks. RESULTS Maximum prevalence of PEX (57 %) was seen in 51 - 60 years of age and 64 % were males and 36 % were females. The involvement was bilateral in 53 % and unilateral in 47 % cases. The range of intraocular pressure (IOP) was 12.4 mm Hg to 23.1 mm Hg. 67 % patients had insufficient mydriasis and 81 % cases were found to have PEX material deposited on the peripheral zone and 19 % cases on both peripheral zone and central zone. A total of 27 % cases had mature cataract and 7 % had hypermature cataract. CONCLUSIONS PEX requires a thorough preoperative planning along with a proper intraoperative care to ensure an uneventful surgery and a successful postoperative result.
