FIELD: medicine.
SUBSTANCE: invention relates to medicine, specifically to ophthalmology. For refractive correction of myopic regression after radial keratotomy, correction by ReLEx SMILE method is performed. Microcut of 1.5 mm is made between the keratotomy incisions. Lenticule is formed with diameter of optical zone in accordance with pupil diameter defined in mesopic conditions. Energy of femtosecond pulse of 125-130 nJ is used. Distance between the pulses is equal to the diameter of the laser spot making 4.3 mcm for the front surface of the lenticular, 4.4-4.5 mcm for the back surface of the lenticule, and 1.7 mcm for the edge of the lenticular.
EFFECT: method provides fast restoration of high visual acuity in the distance with preservation of mechanical strength of cornea frame and its biomechanics, elimination of risk of rupture of flap along old scars, displacement of flap petals, irregular astigmatism associated with longitudinal transverse incision of corneal tissue.
