HERNANDEZ SILVA, Juan Raúl et al. Oblique irrigation chopper in microincision cataract surgery. Rev Cubana Oftalmol [online]. 2008, vol.21, n.2, pp. 0-0. ISSN 1561-3070.
The objective of this study was to present the results of the prechop technique (PCh) combined with microincision cataract surgery (MICS) that was used in cataract surgery by phacoemulsification with the oblique irrigation chopper in the Center of Eye Microsurgery of "Ramón Pando Ferrer" Cuban Institute of Ophthalmology from September, 2006 to January, 2007. The universe of study was made up of 120 patients (eyes) diagnosed with pre-senile and senile cataract and surgically treated. The analyzed variables were age, sex, visual acuity with correction, endothelial microscopy and refractive cylinder during the preoperative and postoperative periods, as well as ultrasound time and most common complications. For this analysis, contingency tables with absolute and relative frequencies and medians, and also Student´s t test for comparing data were used. It was found that cataract prevailed in patients under 60 years; visual acuity with correction improved 5 lines in Sellen chart, the refractive cylinder slightly changed, the time of ultrasound application was within the normal values; loss of endothelial cells was not significant and the most frequent transoperative complication was rupture of posterior capsule with vitreous detachment.
