Abstract
Background. In the available literature, there are isolated publications devoted to the topic of the possible effect of laser correction by the Femto LASIK method on the myopic eye choroid. In this connection, in our opinion, the relevance of continuing research in this direction remains.The aim of this study was to examine the volume of the retina in the macular zone, the thickness of the choroid and the ciliary body using optical coherence tomography on myopic eyes after femtosecond-assisted laser in situ keratomileusis in the short term.Material and methods. 30 patients (30 right eyes) aged 20 to 35 years, suffering from mild and moderate myopia, but without pathological changes in the retina according to OCT, made up the study group. All patients underwent myopia correction using the Femto LASIK method. Before the operation, after 4 hours and the next day, they underwent the examination of the retinal volume in the macular zone, the choroidal and the ciliary body thickness using OCTResults. The analysis of the obtained results of the studied parameters showed that the ciliary body thickness and the retinal volume in the macular zone did not undergo statistically signifi cant changes and remained within the preoperative values (p > 0.05). We observed a tendency to an increase in the thickness of the choroid 4 hours after the operation, but the carried out statistical analysis did not confi rm the reliability of its changes (p > 0.05). On the next day, the choroidal thickness indices practically recovered to the preoperative level (p > 0.05).Conclusion. A study of the retinal volume in the macular zone, the thickness of the choroid and ciliary body using OCT in myopic eyes in the short term after Femto LASIK showed the absence of statistically signifi cant changes in the studied parameters, which indirectly indicates the safety of this method of laser correction for the posterior segment of the eye.

Summary
Выполнялось исследование макулярной зоны сетчатки на приборе RTVue XR (Optovue, США) перед операцией, через 4 часа после операции и на следующий день после лазерной коррекции миопии. Также всем пациентам перед операцией, через 4 часа и на следующий день после лазерной коррекции миопии выполнялась оптическая когерентная томография области цилиарного тела на приборе Visante (Carl Zeiss Meditec AG, Германия). Все числа складывались и делились на четыре; полученное значение принимали за среднее значение толщины цилиарного тела. На первом этапе Фемто-ЛАЗИК для формирования клапана роговицы на фоне медикаментозной анестезии 4%-м раствором инокаина у пациентов исследуемых групп использовали фемтосекундный лазер VisuMaxTM (Carl Zeiss Meditec AG, Германия) Основным результатом исследования была оценка объёма сетчатки в макулярной зоне, толщины хориоидеи и цилиарного тела на основании данных ОКТ. Критический уровень значимости (р) при проверке статистических гипотез принимали равным 0,05
