Recently, small incision cataract extraction by phaco and implantation of a foldable intraocular lense with topical anesthesia has used in an attempt to decrease the complication of general anesthesia and peribulbar injection. To compare effects and complications of topical, local and general anesthesia, 92 patients admitted to Imam Hosein hospital for cataract surgery, were randomly assigned to three groups and surgery was done under different methods of anesthesia. During routine ECCE, lid and globe movements, miosis and viterous bulg were observed more in topical anesthesia than the other techniques, but serious complications such as posterior capsular rupture and viterous loss were not seen. Because of less systemic and local complications and rapid return of vision and possibility of outpatient surgery, topical anesthesia should be considered as an alternative to local and general methods.
