OBJECTIVES: To describe the functional and anatomical results achieved in standard coaxial phacoemulsification using multichop technique in the cataract surgery. METHODS: Prospective longitudinal and descriptive study of patients operated on from cataract at "Ramón Pando Ferrer" Cuban Institute of Ophthalmology, conducted from September 2005 to May 2007. RESULTS: The average ultrasound power was 20,7 %, the average ultrasound time was 46 seconds and the average effective phaco time was 10,3 seconds; there was significant relation between nucleus hardness and time of ultrasound (p < 0.05). Postoperative best corrected average visual acuity was 0,8 with significant relation (p = 0.00) as well as induced astigmatism of 0,37 dioptres. Significant relation was observed between loss of endothelial cells and nucleus hardness (p < 0.05). CONCLUSIONS: The used phacodynamic parameters were low, postoperative visual acuity improved and induced astigmatism was also low.
