Methods:Anterior chamber flare and cells were measured preoperatively and 1 day, 1 week, 1 month and 3 months postoperatively in two groups. In group 1, thirty-two eyes underwent laser photolysis. In group 2, thirty-five eyes underwent conventional phacoe-mulification. Results:Anterior chamber flare and cell measurements had no significant difference between two groups preoperatively and 1 day, 1 week, 1 month and 3 months postoper-atively. Flare and cell values returned to preoperative values by the third month. Conclusions:Postoperative inflammatory response to laser photolysis was equal to conventional phacoemulsification, and recovery occurred in 3 months postoperatively.Eye Science 2004;20:6-9.展开更多
