RISK-FACTORS FOR AN INFLAMMATORY RESPONSE AFTER EXTRACAPSULAR CATARACT-EXTRACTION AND POSTERIOR CHAMBER IOL

Risk factors for developing an inflammatory response after extracapsul ar cataract extraction with implantation of posterior chamber IOL have been studied. Out of 1154 cases included in the study, an inflammator y response was encountered in 63 eyes (5.5%). The inflammatory respons e was defined as increased cellular flare and/or as a fibrinous reacti on during a follow-up of 4 months. Thirteen of the 63 eyes (20.6%) dev eloped cellular precipitates, and posterior synechias were seen in 34 of these eyes (54.0%). Among 10 pre- and 10 peroperative putative risk factors analyzed in a logistic regression model, 5 variables had a st atistically significant influence on the probability of developing pos toperative inflammation; 1) Uveitis in history (p = 0.0001), 2) Pseudo -exfoliation syndrome (p = 0.0224), 3) Inability to obtain adequate my driasis at the start of surgery (p < 0.0001), 4) Problems with IOL imp lantation (p = 0.0111) and 5) Pigment effusion during surgery (p = 0.0 258).
