To assess the clinical results in Laser in situ keratomileusis (LASIK) of two last-generation excimer lasers; broad beam and flying-spot lasers. According to the laser used, the treated eyes were divided into two groups, Group1, 80 eyes of 40 patients with Esiris®; Group 2, 80 eyes of 40 patients with KeratomII®. Each patient had been followed up for more than 2 months after surgery. Mean preoperative spherical equivalents were -6.351.73D (range:-1.50--9.50D) in group 1 and -6.391.35D (range:-2.50--9.75D)in group 2. At postoperative 2 months, mean uncorrected visual acuity increased to 0.91 in group 1 and 0.88 in group2. Uncorrected visual acuity of 20/40 or better occurred in 100% of group 1, and 95.7% of group 2, and of 20/20 or better in 58.3% and 48.5% respectively. Mean spherical equivalents were within 1.00D in 92.6% of group1 and 85.0% of group 2. Intra- or postoperative complications were subconjunctival hemorrhage (2 eyes, group 1;1 eyes group 2), epithelial ingrowth (1 eye, group 2 only), corneal haziness (6 eyes, group 2 only), halo (2 eyes, group 1;5 eyes group 2), photophobia (3 eyes, group 1;9 eyes group 2), and undercorrection (2 eyes, group1;8 eyes group 2).This study shows that eyes treated with LASIK using a Esiris(had better postoperative visual acuity leading to quicker refractive stability and faster visual rehabilitation.
