Evaluation of Posterior Capsular Opacification following Phacoemulsification, Extracapsular and Small Incision Cataract Surgery

摘要

Background: Posterior capsular opacification is the most common complication of modern cataract surgery.Methods: A prospective study was conducted on 150 patients (150 eyes) out of which 50 eyes each underwent cataract surgery byextracapsular cataract extraction, small incision cataract surgery and phacoemulsification technique. On postoperative follow upposterior capsular opacification and Neodymium: Yttrium Aluminium Garnet laser capsulotomy rate was evaluated.Result: Posterior capsular opacification rate was significantly less (p=0.03) in eyes which had undergone phacoemulsification ascompared to extracapsular cataract extraction. However capsulotomy rate was not statistically significant after comparison of thethree surgical techniques of cataract surgery.Conclusion: Posterior capsular opacification following cataract surgery can be minimized by the use of small incision cataractsurgery and phacoemulsification.
