PLASENCIA BLANCO, Abel et al. Phacodynamic outcomes of the reversed chopping technique in the cataract surgery in 2009. Rev Cubana Oftalmol [online]. 2011, vol.24, n.2, pp. 260-270. ISSN 0864-2176.
Objectives: To assess the phacodynamic outcomes of the reversed chopping phacoemulsification technique applied in cataract surgery at “Ramon Pando Ferrer” Cuban Institute of Ophthalmology between January and December, 2009. Methods: A prospective and descriptive study was performed on 182 patients (eyes) diagnosed with pre-senile and senile cataract, who agreed to be operated on with this procedure. The phacodynamic outcomes were evaluated according to the following variables: lens hardness, best visual acuity with/without glasses, ultrasound power, time of phacoemulsification, effective time of phacoemulsification, endothelial cell density and complications. The results were analyzed through contingency tables with absolute and relative frequencies, in addition to applying Student’s t test for comparison. Results: The visual acuity with glasses increased by five lines in the Snellen chart, the ultrasound time applied was within the normal values and correlated with the hardness of the core. The loss of endothelial cells and the surgical complications were irrelevant. Conclusions: The technique was considered very effective and perfectly applicable for all sorts of cataract hardness. This allows avoiding a large number of complications and rapid recovery of patients to be reinserted into their social life.
