Abstract

Background: Posterior capsule opacification (PCO) is one of the most common side effects after cataract surgery. YAG laser posterior capsulotomy is used for the treatment of PCO. This study evaluated the improvement of visual function after ND: YAG laser posterior capsulotomy in patient with PCO after cataract surgery. Methods: In this descriptive study, 48 patients with PCO without underlying disease were selected for ND: YAG laser posterior capsulotomy. Their visual functions included visual acuity, contrast sensitivity and glare sensitivity was measured before and one month after Nd: YAG laser capsulotomy. In addition, we evaluate the correlation between the type of the lens and visual function. Findings: Among 48 patients studied, 21 (43.7%) were male and 27 (56.3%) were female and the average age was 70.6±10.7 years. Average visual acuity, contrast sensitivity and glare sensitivity before Nd: YAG laser capsulotomy was 20/37, 20/83 and 20/95 respectively that changed to 20/24, 20/50, and 20/64 after capsulotomy. Conclusion: Nd: YAG laser capsulotomy improved visual functions (include visual acuity, contrast sensitivity and glare sensitivity). The type of lens used in cataract surgery did not influence these parameters. © 2008, Isfahan University of Medical Sciences(IUMS). All rights reserved.
