Resumen

HERNANDEZ SILVA, Juan R. et al. Surgical results of phacoemulsification by Pre Chop techniques. Rev Cubana Oftalmol [online]. 2004, vol.17, n.2. ISSN 0864-2176.

The aim of this paper was to determine the results obtained with the Pre Chop technique in the cataract surgery by phacoemulsification at the Center of Ocular Microsurgery of "Ramón Pando Ferrer" Ophthalmological Teaching Hospital in 2001. All the patients (eyes) with diagnosis of presenile and senile cataract that received surgical treatment with the Pre Chop technique by phacoemulsification were included in the study. Variables such as age, sex, visual acuity with correction, endothelial microscopy, refractive cylinder in the pre- and postoperative, time of ultrasound and the most frequent complications, were analyzed through contingency tables with mean absolute and relative frequencies. The T student test was used for their comparison. It was observed that cataract predominated among males aged 46-60. The visual acuity with correction improved by 0.64 (20/40) as an average. The refractive cylinder hardly changed, the time of ultrasound applied was within the normal values, the loss of endothelial cells was not significant and the commonest transoperative complication was the rupture of the posterior capsule with protrusion of vitreous and keratitis.

Palabras clave : Pre Chop technique [surgery]; cataract [presenile]; cataract [senile]; surgery [phacoemulsification].
