Abstract |
PURPOSE To present prospective clinical results of laser-assisted in situ keratomileusis (LASIK) using a solid-state laser system for the correction of mild to moderate myopia with or without astigmatism. METHODS: Thirty-eight eyes underwent LASIK using a 213 nm solid-state laser (Pulzar Z1trade mark, CustomVistrade mark, Australia). Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), refractive errors, higher order aberrations (HOA) and contrast sensitivity were evaluated preoperatively and postoperatively. RESULTS: The preoperative and postoperative mean spherical and cylindrical refractive errors were -3.27+/-0.85D, +1.04+/-0.69D, -0.36+/-0.7D and +0.14+/-0.2D, respectively. UCVA over 20/25 was obtained in 27 eyes (93%). A result within 1.00D of the desired correction was achieved in 90% of the eyes. There were no decreases in BCVA within the study group. The preoperative and postoperative root-mean-square of HOA at 3 months were 0.196+/-0.092 microm and 0.326+/-0.107 microm respectively. The preoperative and postoperative contrast sensitivity values were similar. CONCLUSIONS: The clinical outcomes of LASIK using a solid-state laser system were comparable to the conventional refractive surgery in mild to moderate myopia. The 213 nm solid state laser may be an alternative option for refractive surgery. |
