FIELD: medicine.
SUBSTANCE: invention relates to medicine, specifically to ophthalmology. MyoRing ring is implanted in an intra-stromal pocket formed by using a femtosecond laser at depth of 80–87 % of the minimum thickness of the cornea to correct myopia of medium or high degree combined with a thin cornea. For correction of spherical component of refraction in -3.0 D is implanted ring MyoRing with diameter of 5 mm, height of 230 micron and at increase of degree of spherical component of refraction for every -1 D increased height of ring by 10 mcm at constant diameter of 5.0 mm; or implanted MyoRing ring with diameter of 6 mm, height of 260 mcm and increasing degree of spherical component of refraction for each -1 D increase ring height by 20 mcm at constant diameter of 6.0 mm; or implanted MyoRing ring with diameter of 7 mm, height of 290 mcm and increasing degree of spherical component of refraction for each -1 D is increased height of ring by 30 mcm with constant diameter of 7.0 mm.
EFFECT: method improves visual acuity and improves quality of life in patients with myopia.
