Comparison of outcome of LASIK in mild, moderate and high myopia

Background: Lasik-Laser in situ keratomileusis is by for the predominant refractive procedure in use today. We are beginning to learn both its full potential and its limitations. This includes refining our knowledge about how much refractive error can be corrected with LASIK while maintaining a high quality of vision. Aim: To evaluate and compare the outcome of LASIK performed in patients with mild, moderate and severe myopia using SCHWIND ESIRIS excimer laser system. Methods: A hospital based, prospective, randomized case study was conducted on 78 eyes of 40 patients underwent LASIK with SCHWIND ESIRIS Laser system of which 40 eyes were of low myopia, 28 eyes were of moderate myopia and 10 eyes were of high myopia at Vinayaka Mission Hospital, Salem, between January-2010 to December-2010. Results: Preoperative & postoperative BCVA was compared which was found to be statistically significant, there was no postoperative decrease in vision during the 6 months follow up. There was no incidence of corneal ectasia during the 6 months. There was no retreatment in this study. Importantly the safety profile of LASIK in the study was found to be excellent.&nbsp
