Comparative evaluation of PCO development in various methods of cataract surgeries and with different type of IOL implantation
Aims: 1. To clinically evaluate posterior capsular opacification in various types (ECCE, SICS, Phacoemulsifiction) of cataract surgeries; 2. To clinically evaluate posterior capsular opacification in various types of IOL implantation.
Materials and Methods: The source of the data included, Patients with posterior capsular opacification attending the ophthalmic outpatient department after various types of cataract surgeries with various types of IOL implantation. The present study is a hospital based prospective study conducted from October 2012 to April 2014. The duration of the study was one year six months and follow up period of one month.
Results: In this hospital based prospective study 219 patients with posterior capsular opacification were enrolled during a study period of 1 year and 6 months. Out of these 219 patients 200 patients were included in the study. 19 patients were excluded from the study. Out of 19 patients excluded from the study, 3 patient had PCO in post vitrectomised eyes, 3 had macular scars and 4 patient had subluxated IOLs, 4 patients had diabetic CSME and 5 patients were lost for follow up.
Conclusion: Posterior capsular opacification was found more in patients undergoing small incision cataract surgery with rigid intraocular lenses.
Incidence of PCO is more in females compared to males; In the bag IOL implantation had a reduced incidence of PCO; Single piece IOLs are more commonly associated with posterior capsular opacification.
