Resumen

RODRIGUEZ SUAREZ, Belkys et al. Use of prechop technique in phacoemulsification cataract surgery. Rev Cubana Oftalmol [online]. 2013, vol.26, n.1, pp.30-38. ISSN 0864-2176.

Objective: to use the prechop technique in the phacoemulsification cataract surgery and to describe the final results. Methods: descriptive and prospective study of 295 patients (eyes) with senile cataract diagnosis, who were seen at ¨Ramón Pando Ferrer¨ Cuban Institute of Ophthalmology from January to December 2010. The analyzed variables were best corrected and uncorrected visual acuity and endothelial cell count, hexagonality, variability coefficient, refractive astigmatism, effective ultrasound time and complications. Results: the endothelial cell loss was 14.2 %. The postoperative average hexagonality was 50.99 %. The preoperative variability coefficient averaged 32.37 but changed to 30.43 % after surgery. Postoperative average astigmatism was 1.48 D, with induction of 1.51 D. The effective ultrasound time was less than 2 minutes in 80 % of cases. Best uncorrected visual acuity preoperatively was 0.14 and improved to 0.43 in the postoperative phase, but the best corrected visual acuity was 0.29 before surgery and rose to 0.82. The most frequent transurgical complication was rupture of the posterior capsule corneal whereas the corneal edema prevailed after surgery. Conclusions: phacoemulsification using prechop technique is an advantage for the cataract surgery, with an important improvement of final uncorrected and corrected visual acuity, and a very good choice in patients with hard cataract because of the lower impact on the corneal endothelium.
