Purpose: To evaluate the efficacy, safety and reliability of Laser in situ keratomileusis (Lasik) vs Laser assisted subepithelial keratektomy (Lasek) in 30 patients. The acceptance of each procedure performend evaluated and compared intra - individually.
Method: Up to now Lasik and Lasek was performed in 30 eyes of 15 patients. Each patient received Lasik one eye and Lasek in the other eye. The mean preoperative myopic spherical equivalent was -3.6 ± 1.45 diopters (dpt) and the best spetacle-corrected visual acuity (BSCVA) 1.06 ± 0.12 dpt in Lasik eyes, whereas the mean preoperative spherical equivalent was -3.0 ± 0.97 dpt and BSCVA 0.97 ± 0.19 dpt in Lasek treated eyes.
Results: After one month of follow up the uncorrected visual acuity (UCVA) in the Lasik treated eyes was 0.96 ± 0.26 and the Lasek group UCVA = 0.98 ± 0.18. After one week the UCVA of Lasik was 0.86 ± 0.27 and Lasek UCVA 0.66 ± 0.30. After three to six month the UCVA in Lasik group was 0.95 ± 0.23 and in Lasek = 1.04 ± 0.12. The long term better UCVA of Lasek was subjectively ident
