Abstract
Objective:To investigate the safety and efficacy of topical anesthesia in non-phacoemulsification cataract extraction and IOL implantation using small incision.Methods:Under topical anesthesia small incision non-phacoemulsification cataract extraction and IOL implantation were done in 90 patients (102eyes),and the effectiveness of topical anesthesia and postoperative visual acuity were surveyed.Results:All operation were smoothly done under topical anesthesia without any additional retrobulbar or peribulbar anesthesia and all the patients co-operated very well with the operators during the operations.The mean duration of the operation was about 20 minutes (10～45 minutes).The vision≥0.5 was 67.65% (at first postoperative day) and 77.27% (at l week postoperatively) respectively.Conclusion:Small incision non-phacoemulsification cataract extraction and IOL implantation under topical anesthesia is safe and effective.
