• 51 patients (31 women and 20 men) between 21 and 35 years of age, with spherical equivalent from -1,5D to - 6,75D (average -4,35D) were included to the study. • One eye (right) was treated with EBK technique and the second eye (left) with Epi-LASIK. • The standard laser ablation (ASA) was performed using Eximer laser - MEL 80 (Zeiss) • In all cases the mitomycin C was applied after laser ablation. • The therapeutic contact lens was placed on the end of surgery as a routine. • Visual acuity was examined before the surgery and at the following intervals of one week (after removal of contact lens) and one month, 3 and 6 months. • Time of reepithelialization, Confoscan images and patients' satisfaction were analyzed.


• Preoperative BCVA was from 0,7 to 1,0 in all eyes. • BCVA after contact lens removal was from 0,7-1,0. BCVA at 3 and 6 months after surgery was 0,9-1,0. • Postoperative spherical equivalent was comparable in both group from • +0,5 D to -0,75D (average: -0,19 D) • There were no statistical significant differences in postoperative BCVA between both groups. • The reepithelialization time was slightly shorter in EBK group but without statistical significance. • At the time of surgery patients complained about little discomfort during Epi-Lasik ring suction. • Small to moderate subconjunctival hemorrhages were observed in 17/51 eyes after Epi-Lasik. • Patients' satisfaction was greater in EBK group.


1. EBK and Epi-Lasik procedures are safe and efficacious methods of treatment of low and moderate myopia 2. EBK procedure was found as a slightly more comfortable comparing to Epi-Lasik. FINANCIAL INTEREST: NONE
