Abstract
La catarata es una de las principales causas de ceguera en todo el mundo y su extracción quirúrgica es la única terapia admitida como eficaz. Dentro de las complicaciones más frecuentes está la opacidad de la cápsula posterior del cristalino, ésta puede aparecer meses o años después de la cirugía. Ocurre entre el 20% y el 50% de los pacientes en un periodo de 5 años posteriores a la misma. La capsulotomía posterior puede realizarse mediante maniobras manuales con el instrumental tradicional, o con láser, siendo este último la modalidad habitual en la época actual; por estas razones se realiza esta investigación, para conocer los resultados obtenidos después de la capsulotomía con láser en los pacientes operados de catarata por la Técnica Blumenthal en el Hospital Universitario Abel Santamaría Cuadrado, en Pinar del Río (Cuba), durante el periodo junio 2007-mayo 2008. Para ello se tuvieron en cuenta las variables: edad, sexo, implante o no de lente intraocular, complicaciones trans y post láser, así como agudeza visual pre y post tratamiento. El 80.2% de los pacientes estudiados tenía >60 años de edad y en un 96,8% se colocó lente intraocular en cámara posterior. El 65.9% de los ojos presentó elevación transitoria de la presión intraocular y sólo en un 3.2% hubo astillamiento del lente intraocular sin necesidad de extracción. Las complicaciones no cobraron importancia si se considera que el 93.2% de los ojos alcanzó una agudeza visual >0.7.
Cataracts are one of the main causes of blindness all over the world and its surgical removal is the only effective therapy admitted. The opacity of the posterior capsule of the lens is the most frequent post-surgical complication. This may appear months or years after surgery and is present in 20-50 % of the patients after 5 years of their surgical intervention. The posterior capsulotomy may be performed by means of manual procedures using the traditional instrumentation, or by means of laser; the current technique nowadays. Showing the results after laser capsulotomy in patients operated by the Blumenthal Technique (2007-2008) at "Abel Santamaria Cuadrado" University Hospital, in Pinar del Rio Cuba was the purpose of this paper. Age, sex, implant and non- implant of the intraocular lenses (IOL), complications during trans and post laser therapy, as well as the visual acuity before and after treatment were the variables considered, all patients were older than 60 years (80, 2 %) and in 96, 8 % an intraocular lens was placed into the posterior chamber, 65.9 % of the eyes showed transient increasing of the intraocular pressure, and only 3, 2 % showed splintering of the IOL, but needing no extraction. Complications were not so important if it is considered that 93, 2 % of the eyes reached to a visual acuity > 0, 7.
