FIELD: medicine, ophthalmology.
SUBSTANCE: height of the implanted intrastromal ring is selected to correct high myopia. The height of the implanted ring is determined by selection with parameters from 200 to 400 µm in increments of 20 µm. The refractive effect is predicted on the basis of regression analysis according to the formula R1+0.005×h+0.001×C, taking into account the height of the implanted ring h, the depth of its occurrence in the stroma C and the initial radius of curvature of the cornea R1.
EFFECT: increasing the predictability of the refractive effect and achieve maximum clinical and functional results.
