ABSTRACT
PURPOSE: To evaluate LASIK results obtained with the IntraLase femtosecond laser to correct myopia. METHODS: This was a prospective, single masked observer study. Flaps were created with the IntraLase femtosecond laser (FS). All laser procedures were performed by the same surgeon using the Technolas 217 excimer laser (Bausch & Lomb). We have analysed the uncorrected visual acuity (UCVA) at 1 day, 1 week, 1 month and 3 months after surgery and best spectacle-corrected visual acuity (BSCVA) after 3 months. RESULTS: 485 eyes with myopia were treated and their results evaluated. The mean preoperative sphere was of -3.9 D (SD 2.0) and a mean astigmatism of -0.9 D (SD 0.9) with BSCVA 1.1 (SD 0.1). The UCVA results were 0.94 (SD 0.1) at the first day postoperatively visit, 0.96 (SD 0.1) at first week, 1.00 (SD 0.1) at one month and 1.00 (SD 0.2) at 3 months. The refractive error at 3 months was -0.02 D (SD 0.3) and -0.1 D (SD 0.3) of myopia and astigmatism respectively. At 3 months 96.9% of eyes were within +/-1.00D and 93.6% of the eyes were within + 0.50 D. CONCLUSIONS: LASIK to correct myopia is a safe, effective and predictable procedure using IntraLase FS to create the flap.

Objetivo: Evaluar los resultados refractivos del LASIK utilizando láser de femtosegundo (Intralase) para tallar el colgajo corneal, en la corrección de miopía. Métodos: Se trata de un estudio prospectivo, observador enmascarado. Los colgajos fueron tallados con láser de femtosegundo (IntraLase). Todos los procedimientos láser fueron realizados por el mismo cirujano utilizando el láser Technolas 217 (Bausch & Lomb). Se evaluó la agudeza visual sin corrección (AVsc) al primer día, semana, primer y tercer mes después de la cirugía, así como la agudeza visual mejor corregida (AVCC) a los tres meses de la cirugía. Resultados: Evaluamos los resultados refractivos de LASIK en 485 ojos miopes. El defecto refractivo previo era de -3,9 D (DE 2,0) esfera y de -0,9 (DE 0,9) cilindro con una AVCC inicial de 1,1 (DE 0,1). Los resultados de la AVsc fueron de 0,94 (DE 0,1) al primer día postoperatorio, 0,96 (DE 0,1) a la aislasemana, 1,00 (DE 0,1) al mes y 1.00 (DE 0,2) a los 3 meses. La refracción manifiesta a los 3 meses fue de -0,02 D (DE 0,3) y -0,1 D (DE 0,3) de miopía y astigmatismo respectivamente. El 96,9% de los pacientes a los 3 meses estaban dentro de un equivalente esférico de ± 1,00 D y el 93,6% de los mismos se encontraban dentro de un equivalente esférico de ± 0,50 D. Conclusiones: Los resultados obtenidos en nuestra experiencia parecen demostrar que el LASIK realizado utilizando láser de femtosegundo, es un método seguro, eficaz y predecible para la corrección de miopía
