Abstract
Aim : Pseudoexfoliation (PXE) is a common and clinically important systemic condition in elderly people that affects the outcome of cataract surgery. It can cause various complications during cataract surgery due to pupillary rigidity and zonular weakness and instability. The purpose of this study was to evaluate the frequency and types of complications of Phacoemulsification in patients with cataract and PXE. Materials and Methods: This cross sectional, prospective study was carried out on 60 eyes of 60 patients with cataract and PXE who underwent phacoemulsification in a tertiary care hospital. Their perioperative and post-operative complications were documented and analyzed. Results: Poor pupillary dilatation in spite of use of standard mydriatic drops and NSAID was the most common perioperative finding. This single factor made subsequent steps of surgery more difficult due to poor visualisation. Conclusion: Presence of associated PXE in cataract patients significantly increases the risk of vision threatening complications. Use of flexible iris hooks for small pupils, capsular tension rings for capsular stability and high viscosity viscoelastics are useful adjunct during surgical technique for good visual outcome.
Highlights
Pseudoexfoliation was first described by Lindberg in 1917[1]; who said this material was created by earlier inflammation
Sixty eyes of 60 patients with PXE who underwent cataract surgery (Phacoemulsification technique) and completed 6 weeks follow up were included in this study to evaluate the perioperative and post-operative complications
2 patients originally posted for phacoemulsification had to be converted to SICS due to intraoperative difficulties leading to PC rent 13 cases had poor pupillary dilatation. 47 cases had moderate pupil dilatation
Summary
Pseudoexfoliation was first described by Lindberg in 1917[1]; who said this material was created by earlier inflammation. It was described by Swiss Ophthalmologist Alfred Vogt in 1918[1]; who said it as a film on the anterior lens capsule as a remnant of the pupillary membrane. Found that such patients have 5 times greater risk of intraoperative complications in cataract surgery compared with normal cases. Recognition of this condition is very important before starting surgery on such patients
