Claims (1)

Способ эксимерной лазерной коррекции несимметричного астигматизма, заключающийся в воздействии на роговицу излучением лазера, отличающийся тем, что первоначально определяют положение оси наибольшего миопического астигматизма и координаты центра наибольшей рефракции, далее смещают максимум энергетического распределения Гауссова пучка излучения лазера в сторону центра участка с наибольшей рефракцией, совмещая центр Гауссова пучка с его центром, при этом энергия излучения 120-250 мДж/см2, частота от 1 - 15 Гц, диаметр пятна рассеивания на роговице от 1 - 6 мм.The method of excimer laser correction of asymmetric astigmatism, which consists in exposing the cornea to laser radiation, characterized in that the axis of the greatest myopic astigmatism and the coordinates of the center of greatest refraction are initially determined, then the maximum energy distribution of the Gaussian laser beam is shifted toward the center of the site with the greatest refraction, combining the center of the Gaussian beam with its center, while the radiation energy is 120-250 mJ / cm 2 , the frequency is from 1 - 15 Hz, the diameter of the scattering spot on p ogovitse from 1 - 6 mm.
