OBJECTIVES: To describe the morphofunctional results of the stop and chop technique in cataract surgery in phacoemulsification at the Eye Microsurgery Center of "Ramón Pando Ferrer" Cuban Institute of Ophthalmology from June 2006 to March 2009. METHODS: A cross-sectional descriptive study was conducted. The universe and sample of the study were all the patients diagnosed with presenile and senile cataract, who met the selection criteria and accepted to undergo the surgical technique in question, that is, 201 operated eyes. These data were analyzed through the contingency tables with relative and absolute frequencies; additionally means were used in the SPSS data processing software, version 11.1, in which Student´s t test served for their comparison. RESULTS: It was found that cataract prevailed in over 70 years-old and in 33,4 % of patients. The best visual acuity with correction increased to reach seven lines in Snellen´s chart in 93 % of cases. The refractive cylinder barely changed in 0,15 dioptres and the loss of endothelial cells occurred in 8,2 % of patients and the operative complications were 1,5 %. CONCLUSIONS: The age of the patients undergoing the cataract surgery through stop and chop technique was mostly over 70 years. The postoperative better corrected visual acuity increased 7 lines in Snellen´s chart; induced astigmatism was lower than 0,5 dioptres; cell loss and the postoperative complications were not significant.
