| Popis: | Purpose. To compare visual and refractive results of Femto LASIK using with optimized and conventional ablation algorithms for «Microscan Visum 1100 Hz» excimer laser i n myopia patients.Material and methods. In this study were included 146 eyes of 146 patients with myopia who had undergone Femto LASIK procedure using the different ablation algorithms: optimized and conventional. All patients underwent complete ophthalmological examination before laser refractive surgery, on the 1st day and 1, 3, 6, 12 months after F emto LASIK.Results. There was no statistically significant difference between the groups in the postoperative values of the sphere, cylinder, and SE refraction (p>0.05). After surgery visual acuity without correction of 1.0 and higher was observed in 89% in the main group and in 90.5% in the control group. There was no loss of CDVA lines in post-op period. The gain in one or more lines of CDVA was noted in 19.4% and 17.6% in the main and control groups, respectively. The FemtoLASIK surgery predictability within ±0.5 diopters were 90.3% in the main group and 90.5% in the control group; within ±1.0 diopters in 100% and 100%, respectively. Visual and refractive results showed no statistically significant difference between the two groups (p>0.05).Conclusions. 1. Femto LASIK procedure using with optimized and conventional ablation algorithms for «Microscan Visum1100 Hz» is an effective, safe and predictable method for myopia correction. 2. Optimized algorithm allows to reduce ablation depth without changing of the effective optical zone diameter. |
