Purpose: To correct refractive errors laser in situ keratomileusis (LASIK) has become worldwide the primary procedure. The purpose of this study was to evaluate safety, predictability, efficacy, stability and complications using newest LASIK technology with a follow-up of 3 years.
Method: Thirty-two LASIK operations (patients with an age between 17 to 55 years) were evaluated. The microkeratome Hansatome with a superior hinge and the excimer laser Keracor 217 were used. The mean preoperative spherical equivalent was -6.21 ± 2.81 D (-1.63 to -12.0 D), the mean sphere -5.63 D, the mean astigmatism -1.16 D. Ophthalmological examinations were performed preoperatively, after 1 and 7 days and after 1, 4, 12 and 36 months. Safety, predictability, efficacy, stability of the refractive results and complications were evaluated using the Datagraph software program.
Results: In 0% of the cases 2 lines of best-corrected visual acuity (BCVA) were lost, in 9% 1 line, 53% remained unchanged, 28% gained 1 line, 9% 2 lines. 88% of the treated eyes were postoperatively in the range of ± 1.0 D, 77% ± 0.5 D. The uncorrected visual acuity were in 87% of the eyes Zurück | Back
