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 Intra-Lase 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.
