Оценка рефракционного эффекта фемтолазик в коррекции гиперметропии у пациентов с исходно высокой некоррегированной остротой зрения

Abstract

Hypermetropic refraction is not always accompanied by a decrease in uncorrected visual acuity (UCVA) and can be 0.9–1.0. This explains that, despite asthenopic complaints and the difficulty of working near, quite often such patients do not use optical correction. At the same time, patients with high and moderate hypermetropia, having uncorrected visual acuity exceeding 0.8, are usually denied refractive interventions, recommending the use of optical correction. The purpose was to evaluate the results of the refractive effect of hypermetropia correction by Femtolasic in patients with initially high uncorrected visual acuity. On the first day after surgery, all patients experienced an increase in visual acuity near 1–2 lines, at the same time, in 70 % of cases, there was a decrease in UCVA in the distance from 0.5 to 1 line, the total number of aberrations decreased by 4 times. A month after treatment, UCVA in the distance in all patients was maximal and was in the range of 0.9–1.1, UCVA in the vicinity varied from 0.9 to 1.0, the total number of eye aberrations averaged 1.13 ± 0.18, which was almost 3 times lower than preoperative values. All patients were satisfied with the quality of vision near and at an average distance, and noted an increase in visual acuity in the distance and the ability to work comfortably with a computer for a long time. The improvement of the quality of vision and accommodation adaptation in the early stages after surgery indicate the expediency of the treatment in patients with grade 2 and 3 hypermetropia with initially high rates of UCVA.
