Abstract
- Laser in-situ keratomileusis has been performed on 2023 eyes of 1162 patients with myopia of 1-18 diopters and complex myopic astigmatism of 0.75-5 diopters. A Hansatome TM 230 HT keratome and Nidek EC 5000 eximer laser device were employed. The resultant refraction and visual acuity were analyzed during one year postoperation in different age groups and groups with myopia of different degree. In myopia of up to 6 diopters high visual acuity without correction (0.93-0.99) was attained in all age groups. In higher myopia, visual acuity has been increasing over the entire period of observation, the gradient of its alteration being 0.17-0.27. The final visual acuity formed in presbiopes during 3 months. The spherical refraction equivalent of up to 1 diopter was 96.1%. The mean refraction values were stable during the entire period of observation. In myopia of 9.5 diopters and higher the residual myopia in patients aged over 30 years was approximating 1.0 diopters. Hypercorrection was observed in 1.3%, hypocorrection in 2.6% cases. The described combination of equipment for laser keratomileusis provides stable visual and refraction results at a lower incidence of complications.
