INTRAOPERATIVE AND POSTOPERATIVE COMPLICATIONS OF CATARACT SURGERY IN PATIENTS WITH NON-GLAUCOMATOUS PSEUDOEXFOLIATION – A HOSPITAL BASED STUDY
Abstract
Aims: The objectivesof this study are to determine the frequency and types ofcomplications during cataract surgery in patientshaving Pseudoexfoliation syndrome and cataract.
Method: This prospective study was conducted over six months on patients having pseudoexfoliation undergoing small incision cataract surgery. Patients with normal intraocular pressure, normal cup disc ratio and open angles were included. Patients on anti-glaucoma medication or any other ocular pathology were excluded. Intraoperative and postoperative findings upto 40th day were noted.
Results: Out of 40 patients having pseudoexfoliation, 26 were males (65%). 22 patients (55%) have small non dilating pupil. Intraoperative complications include zonular dialysis due to weak zonules (2.5%), posterior capsular rent (5%), vitreous loss (2.5%), iridodialysis during nucleus delivery (2.5%), sphincterotomy (7.5%). Postoperative complications include irregular pupil due to sphincterotomy (7.5%%), anterior chamber reaction (45%), exudative membrane formation (5%), corneal oedema with striate keratopathy (37.5%), raised intraocular pressure (12.5%), iris pigment dispersion (17.5%) and intraocular lens decentration(2.5%).
Conclusion: Intraoperative complications should be expected in patients having pseudoexfoliation even without glaucomatous changes due to poor dilation of pupil and weakness of zonules. First postoperative day visual acuity in pseudoexfoliation patients undergoing cataract surgery was found to be low due to severe anterior chamber inflammation causing elevated intraocular pressure and corneal edema.
