Study of Prognostic Indicators in Patients with Pseudoexfoliation Syndrome Undergoing Cataract Surgery
Abstract
Introduction: Pseudoexfoliation syndrome is a systemic disorder characterized by deposits on the lens and the iris. This syndrome has been reported to be associated with increased intraoperative and post operative complications during cataract surgery. In this study we have documented the complications occurring during small incision cataract surgery(SICS) in pseudoexfoliation syndrome and compared the same with prognostic indicators like pupillary dilatation. Aim: To document and compare the complications occurring during small incision cataract surgery in pseudoexfoliation syndrome with different grades pupillay dilatation as a prognostic indicator. Materials and Methods: The study was conducted at Shri Sathya Sai Medical College and Research Institute Hospital by including 50 eyes of 50 patients with pseudoexfoliation over a period of one years, between July 2014 and June 2015 after obtaining ethical clearance. All the patients underwent small incision cataract surgery (SICS) and were followed up for 6 weeks post surgery. Results: All our patients were aged more than 50 years. About 64% patients belonged to the age group of 70 – 80 years. About 20 (40%) patients had a rigid pupil which dilated not more than 3.5 mm. Zonular dialysis was seen in 8 (16%) patients and of these patients five also had vitreous loss. Four patients had subluxated PCIOL when seen on long term follow up after six weeks. Conclusion: Poorly dilating pupil is a common accompaniment with this condition and is an important prognostic indicator of intraoperative zonular dialysis and vitreous loss, the rate of these complications being inversely proportional to the maximum pupillary dilatation. Patients with poorly dilating pupil need to be given realistic expectations regarding the complications and recovery time. Sphincterotomy can be useful when modern pupil dilating devices are not available.
