Purpose:To evaluate risk factors of posterior capsule opacification after phacoemulsification ocurring during the first six months defined as early posterior capsule opacification. Methods:We retrospectively analyzed 180 eyes of 149 patients consecutively operated of cataract by phacoemulsification between January and July 2001. We evaluated the percentage of early posterior capsule opacification and tried to demonstrate risk factors. Results:6 eyes of 6 patients developed posterior capsule opacification in the first 6 months representing 3,33%. Cataract form was the only preexisting factor we found implicated in the early opacification. Age, eye or general history of the patients did not appeared to be risk factors. The role of the material of intra ocular lens was not evident. Conclusions: Posterior capsule opacification is one of the major complications of phacoemulsification. Usually it appears at least 12 months after surgery. Early capsule posterior opacification in the first 6 months is unusual. The only risk factor found in this study was the form of lens opacification with posterior subcapsular cataracts. Best prevention resides in surgical techniques with atraumatic surgery, thorough removal of lens epithelial cells and cortical remnants using hydrodissection and polishing of the equatorial fornix and the central posterior capsule. Further study are necessary to identify others risk factors.
