A study of clinical profile and factors associated with development of PCO in patients undergoing ND: YAG Laser posterior capsulotomy

Background: Posterior capsular opacification (PCO) is most prevalent complication after Cataract Surgery (Cat Sx) causing of reduced visual acuity (VA). Despite advances in Cat Sx and IOL technology, PCO may develop and require treatment. Nd:YAG laser capsulotomy is standard treatment for visually significant PCO. This study aimed to evaluate common factors associated with PCO development requiring Nd:YAG laser capsulotomy.Materials and Methods: Retrospective observational study was conducted in Ophthalmology department of tertiary care hospital. Medical records of patients undergoing Nd:YAG laser capsulotomy for PCO during 6 months study period were reviewed. Data regarding age, type of cataract and Cat Sx, IOL material, PCO type, interval bet. Cat Sx and capsulotomy and VA before and after procedure were analysed with descriptive statistical methods.Results: Total 156 eyes were analysed. Largest proportion of patients were
