Abstract
Este trabajo se propuso determinar la efectividad del neodimio YAG láser (Nd-YAG láser) en la realización de capsulotomía posterior a 150 pacientes (ojos) operados de catarata senil o presenil en el centro de Microcirugía Ocular en Serie del Hospital Oftalmológico Docente "Ramón Pando Ferrer" en el período comprendido de febreroa diciembre de 1999. En este grupo se analizaron como variables la edad, sexo, raza, implante o no de lente intraocular, tipo de opacidad de cápsula posterior, agudeza visual con corrección pre y postratamiento, complicaciones encontradas, comportamiento de la presión intraocular, así como la energía empleada para realizar dicho proceder. Estos datos se analizaron a través de tablas de contingencias Chi cuadrado. Como resultado de esta investigación se encontró que el láser es altamente efectivo para el mejoramiento de la agudeza visual en los pacientes afectados de catarata secundaria (74,7 %). Se observó además aumento transitorio de la presión intraocular en las dos primeras horas posteriores al láser (60,7 %), y no se encontró ninguna complicación que afectara la visión de los ojos estudiados
The aim of this paper was to determine the effectiveness of neodymium YAG laser (Nd-YAG laser) on performing the posterior capsulotomy in 150 patients (eyes) operated on of senile or presenile cataract at the Center of Serial Ocular Microsurgery (CSOM) of "Ramón Pando Ferrer" Ophthalmological Teaching Hospital from February to December 1999. Age, sex, race, implantation or not of the intraocular lens (IOL), type of opacity of the posterior capsule, visual acuity with pre- and posttreatment correction (Avcc), complications found, behavior of the intraocular pressure (IOP), as well as the energy used to carry out such procedure, were analyzed. The Chi square contingency tables were used to this end. As a result of this research, it was found that the laser is highly effective for improving visual acuity in patients affected with secondary cataract (74.7 %). It was also observed a transitory increase of the IOP during the first 2 hours after laser (60.7 %) It was not observed any complication affecting the vision of the studied eyes
