Small incision non-phacoemusification cataract extraction and IOL implantation under topical anesthesia

Objective To evaluate security and efficacy of topical anesthesia in small incision non-phacoemulsification cataract extraction and IOL implantation.Methods All patients were divided into 2 groups. In group A,one hundred and seventeen eyes of 114 patients were under topical anesthesia with 0.4% Benoxil; in group B,one hundred and ten eyes of 108 patients were under retrobalbaranesthesia and topical anes- thsia.Small incision Non-phacoemulsification cataract extraction and IOL implantation were performed in all patients.The security and efficacy of anesthesia and surgery time were analyzed. Results All the operations were smoothly done. The incidence of complication of anesthesia and the surgery time of group A were less than that of group B. Conclusion Small incision non-phaooemulsification cataract extraction and IOL implantation under topical anesthesia is safe and effective.
