Evaluation of capsular tension ring implantation in phacoemulsification of cataracts with pseudoexfoliation syndrome

Purpose: To study the safety and efficacy of capsular tension ring in cataracts with pseudoexfoliation syndrome in terms of intraoperative and postoperative complications and to assess the visual acuity postoperatively in CTR and non CTR implanted patients. Method: This prospective study included 100 patients with cataracts with pseudoexfoliation syndrome. Patients were randomized into two groups comprising 50 each. Group I underwent CTR implantation Group II had no CTR implanted. Intraoperative variables such as small pupil, extension of capsulorhexis, zonular separation, posterior capsule rupture and vitreous loss were assessed. Postoperative best corrected visual acuity was also assessed. Results: In our study we found that 1(2%) patient out of 50 patients who underwent CTR implantation had zonular dialysis compared to 6(12%) out of 50 patients in non CTR group which was statistically significant (p=0.013) and also there was decrease in incidence of posterior capsular rupture noted in 2(4%) in CTR group and 8(16%) in non CTR group which was statistically significant (p value=0.042). Conclusion: We found that, CTRs ensure safe removal of crystalline lens and stable placement of the IOL during phacoemulsification of eyes with pseudo exfoliation syndrome, thus preventing the risk of intraoperative & postoperative complications & improve patient outcomes.
