%X Se efectu¨® un estudio descriptivo, longitudinal y retrospectivo de los 264 pacientes operados de astigmatismo mi¨®pico mediante LASIK en el Centro Oftalmol¨®gico del Hospital General Docente "Enrique Cabrera" de La Habana, durante el 2009, con vistas a caracterizarles luego del tratamiento quir¨²rgico. En la casu¨ªstica primaron el sexo femenino (61,7 %) y el grupo etario de 20-30 a os (41,3 %), as¨ª como la agudeza visual preoperatoria de cuenta dedos a 0,2 (62,8 %) y la posoperatoria de 0,6 a 1,0 (98,1 %). Despu¨¦s de aplicada la terap¨¦utica, la esfera disminuy¨® en 95,0 % de los integrantes de la serie a valores entre 0,00 y -1,00 dioptr¨ªas y el cilindro, en 98,7 %, con medidas inferiores a -1,50 dioptr¨ªas. Los valores queratom¨¦tricos de 41,25 a 43,00 dioptr¨ªas estuvieron presentes en 72,1 % de los afectados y el equivalente esf¨¦rico mostr¨® un acercamiento sustancial a la emetrop¨ªa en 82,3 % de las intervenciones, con un intervalo entre -1,00 y 0,00 dioptr¨ªas. A descriptive, longitudinal and retrospective study was carried out in 264 patients operated on myopic astigmatism by means of LASIK at "Enrique Cabrera" General Teaching Hospital from Havana, during 2009, in order to characterize them after surgical treatment. Female sex (61.7%) and age group between 20 and 30 years (41.3%) prevailed in the case material, as well as preoperative and postoperative visual acuity of counting fingers of 0.2 (62.8%) and 0.6 to 1.0 (98.1%) respectively. After the treatment have been applied, in 95.0% of patients from the series the sphere decreased to values between 0.00 and -1.00 diopters, and the cylinder, in 98.7%, measuring less than -1.50 diopters. Keratometric values from 41.25 to 43.00 diopters were present in 72.1% of those affected and the spherical equivalent showed a substantial approach to emmetropia in 82.3% of the surgeries, with a range between -1,00 and 0,00 diopters.
