THE PROBLEM OF PREDICTING THE REFRACTIVE EFFECT IN FEMTOSECOND LASER CORRECTION OF MEDIUM AND HIGH HYPEROPIA

was to evaluate the long-term refractive effect of Femto Lasic technology in the correction of moderate to high hyperopia associated with hypermetropic astigmatism. The study included 68 patients (68 eyes) aged 17 to 42 years (26.12±4.89), the ratio of women: men - 40%: 60%. Inclusion criteria: moderate to high hypermetropic refraction from 3.75 to 9.0 dptr (6.48 ±1.1) and hypermetropic astigmatism from 0.5 to 6.0 dptr (2.47±1.5). The Femto Lasic operation was performed according to the standard technology, where the first stage was the formation of a corneal flap using a VizuMax femtolaser using a fast mode (180 nJ, spot distance 4.5 µm), and the second stage was corneal ablation using a MEL 80 excimer laser. On the first day after the operation, in 54% of cases (37 eyes), myopic refraction from 0.25 to 3.0 dptr was obtained, in 29.8% (20 eyes), hyperopia was preserved in the range from +0.25 to +1.75 dptr, in 16.2% of cases (11 eyes), emmetropia was achieved. After 12 months, hypermetropic refraction from 0.5 to 4 dptr prevailed in 67.6% (46 eyes), myopia persisted in 21.6% (15 eyes) from 0.5 to 1.25 dptr, and emmetropia prevailed in 10.8% (7 eyes). Femto Lasik is highly effective in the correction of medium and high hyperopia associated with hypermetropic astigmatism.
