ABSTRACT

Objetivo: evaluar los cambios endoteliales y resultados visuales en los ojos de pacientes con diagnóstico de catarata senil, operados por técnica de facoemulsificación por pre chop o extracción extracapsular del cristalino por túnel esclerocorneal.Métodos: se realizó un estudio descriptivo y prospectivo de 100 pacientes (ojos) atendidos en el Instituto Cubano de Oftalmología Ramón Pando Ferrer, de septiembre a diciembre de 2010. La mitad fueron operados por facoemulsificación y el resto por túnel esclerocorneal. Se analizaron las variables: mejor agudeza visual corregida y sin corrección, dureza del cristalino, conteo celular endotelial, hexagonalidad, coeficiente de variabilidad, astigmatismo medio inducido y tiempo efectivo de ultrasonido...


Objective: to evaluate the endothelial changes occurred and the visual results achieved in the eyes of patients diagnosed with senile cataract, who were operated on either by the prechop phacoemulsification technique or by the extracapsular extraction of the crystalline through the scleracorneal tunnel.Methods: a prospective and descriptive study of 100 patients (eyes) seen at Ramón Pando Ferrer Cuban Institute of Ophthalmology from September to December 2010 was conducted. One half was operated on by phacoemulsification whereas the other underwent scleracorneal tunnelized extraction. The analyzed variables were: best uncorrected and corrected visual acuity, endothelial cellular count, hexagonality, variability coefficient, mean induced astigmatism and effective phaco time...
