Purpose This study aimed to show the effect of yttrium aluminum garnet (YAG) laser posterior capsulotomy opening size on intraocular pressure (IOP) and central macular thickness (CMT). Patients and methods Two hundred eyes having posterior capsule opacification were included in this study. These eyes were classified into two groups: the first group (100 eyes) had undergone small YAG laser posterior capsulotomy, whereas the second group (100 eyes) had undergone large YAG laser posterior capsulotomy. Eyes in both groups were carefully examined preoperatively and at 1 day, 3 days, 1 week, 1 month, 3 months, and 6 months postoperatively. In each visit, IOP and CMT were recorded in all eyes, and the results were compared between both groups. Results Patients in the second group with large YAG laser posterior capsulotomy opening size showed significantly higher IOP and higher CMT. Conclusion Neodymium : YAG laser posterior capsulotomy is a safe technique even with the presence of some possible complications like increased IOP, which is controlled rapidly after the first postoperative day, and macular edema, which improved rapidly with no long-lasting effect on vision.
