Posterior Capsule Opacification Following Cataract Surgery.
J Coll Physicians Surg Pak Jan ;11(6):352-4.

Objectives: To find out the incidence of posterior capsule opacification (PCO) following cataract surgery and means for its management. Design: An interventional study. Place and Duration of Study: The study was conducted at Eye Department, Military Hospital Rawalpindi from June, 1993 to June, 1997. Subjects and Methods: Two hundred patients operated for cataract which included 100 patients of simple cataract extraction, while remaining patients were implanted with posterior chamber intra-ocular lens. Those who reported visual deterioration due to PCO were thoroughly investigated and YAG laser capsulotomy was performed in all such patients. Results: The study revealed a higher incidence of PCO in younger age group, 26(13%) patients developed PCO, pearl type was the most common, 6(23.07%) patients had ruptured anterior vitreous face, 4(15.38%) patients showed rise in intra-ocular pressure while one (03.84%) patient showed evidence of cystoid macular edema. The patients were treated with Neodymium- yttrium-Aluminium, Garnet (Nd-YAG) laser. Conclusions: The PCO is the most common complication responsible for visual deterioration following cataract surgery that can be reduced by thorough removal of lens epithelial cells and cortical remnants. Nd-YAG laser capsulotomy is non-invasive and most favoured treatment.
