Aim of investigation is analysis of the high degree myopia surgical correction effectiveness with the photorefractive keratectomy (PhRK) (MAGEK) and the lens refractive substitution (LRS) methods.

Materials and Methods. 269 patients (507 eyes) are examined; 111 humans (210 eyes) of them with a myopia of 6.5 to 13 D are examined after the PhRK; 158 patients (297 eyes) with a myopia of 6.5 to 22 D — after the LRS. All the patients were divided into 5 groups. The PhRK (MAGEK) was accomplished in two groups at the MEL-70 and ESIRIS laser installations. The operations according to a phacoemulsification method were accomplished in three groups at the Millenium microsurgical system. A period of observation was 2 years.

Results. The best vision acuity was in groups with the PhRK method intervention.

Conclusion. A photorefractive keratectomy in the MAGEK modification is a selection method for correction of the high degree myopia at a sufficient thickness of cornea. A refractive substitution of a lens is effective method of correction for the patients with the contraindications to a keratorefractive surgery.
