OBJECTIVE: To describe the results found in patients operated from cataract by the Phaco-Prechop technique using the topical anesthesia. METHODS: A prospective, observational and descriptive study was performed in 30 eyes (19 patients), seen at the Center of Ocular Microsurgery of "Ramón Pando Ferrer" Cuban Institute of Ophthalmology and operated from cataract by phacoemulsification using the prechop technique and the topical anesthesia, was in the period of July to September 2009. These patients underwent endothelial microscopy before and after the surgery with the objective of determining any change in the cellular density. The pain and the surgeon's comfort measured in a satisfaction scale were evaluated. Variables such as age, cellular average, pain, the surgeon's comfort and the best pre and postoperative corrected visual acuity were analyzed. The information was processed through the absolute and relative frequencies, the mean and Student´s t test. RESULTS: The average age of the patients was 62 years -minimum 46 and a maximum 94 years. The cellular loss was minimal. A small number of patients felt pain at certain moment of the surgery; therefore the surgeon's comfort was not affected in a significant way during the surgery. The visual gain was found to be five lines in the Snellen´s chart. CONCLUSIONS: The topical anesthetics turned to be very useful in the cataract surgery using the phaco-prechop technique, thus avoiding other more invasive anesthestic paths for the patients.
