"Surface ablation may be an alternative to LASIK for those preoperative patients at risk," Richard M. Davis, MD, said at the American Society of Cataract and Refractive Surgery meeting.
Epi-LASIK procedures were performed with the Zyoptix XP Epi-LASIK platform (Bausch & Lomb) used in conjunction with the Technolas excimer laser (Technolas Perfect Vision). A retrospective interventional case series included 42 eyes with myopia or myopia with astigmatism. Patients with severe dry eye or abnormal corneal topography were excluded. Mean preoperative sphere was –3.42 D and mean cylinder was –0.56 D. Mean preoperative spherical equivalent was –3.70 D.
Efficacy (postop uncorrected visual acuity over preop best corrected VA) was .64 at 1 week, .93 at 1 month, 1.07 at 3 months and 1.06 at 6 months. Safety (postop BCVA over preop BCVA) was .83 at 1 week, 1.02 at 1 month, 1.07 at 3 months and 1.06 at 6 months, he said. At 3 months and 6 months, no patients lost lines of VA; 34% of patients gained one line or more at 3 months and 28% gained at least one line at 6 months.
