Introduction: The prevalence of Pseudoexfoliation (PXF) syndrome increases dramatically with age and varies considerably among populations worldwide. Pseudoexfoliation causes serious complications during cataract surgery such as zonular dialysis, capsular rupture and vitreous loss etc.Hence we took up this study to analyse the intra operative complications and postoperative visual outcome of pseudoexfoliation on cataract surgery. Materials and Methods: A cross sectional, hospital based, descriptive study done on 50patients attending the department of ophthalmology, wereevaluated for pseudoexfoliation syndrome. Results and Observations: We had 6 cases (12.00%) of patients aged between41-50 years, between 51-60 years we had 10 cases (20.00%),between 61-70years we had 19 cases (38.00%) and above 70 years we had 15 cases (30.00%). There were 24.00% of femalesand 76.00% of males in the study. The disease was unilateralin 24.00% and Bilateral in 76.00%, Chi-squaretestshowed p= 0.002 which wassignificant. The distribution of pseudoexfoliationmaterialwas as follows - in the corneal endothelium it was seen in8.00%, pupillary margin it was seen18.00%,in the iris it was seen 16.00%, in the lens it was seen 20.00% andiris,pupillary margin and lens it was seen38.00%.The intraoperative complications wereiridiodialysis in 2.00%, rhexis extensionin 2.00%, posterior capsular rent in 4.00% and zonular dialysis in 2.00% Thepostoperative complications werepostoperative hyphema in 6.00%, corneal edema in 8.00%, anterior chamber reaction in 8.00%, retained lens matter in 2.00%,decentered IOL in 2.00%, irregular pupil in 8.00% and IOP elevation in 8.00%. The reasons for reduced visual acuity in the post-operative period were persistent corneal edema (in4.00%), posterior capsular opacification (in2.00%)and cystoid macular edemain(2.00%). Conclusion: In the study we concluded that pseudoexfoliationsyndrome is an age-related disorder where there is anincreased risk ofintraoperative complications that can hamper the vision in the post-operative period. Thus it is imperative that detailed pre-operative evaluation be done in order for the surgeonto manage the complications efficiently |
