title: [LASIK results of IntraLase femtosecond laser to correct myopia: efficacy, security and predictability].
abstract: OBJECTIVE
  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.
