Clinical-diagnostic investigation has been carried out on 31 eyes of 24 patients with. All patients underwent the correction of post-radial keratotomy (post-RK) refractive disorders with topography-guided laser in situ keratomileusis. Preoperatively, the mean uncorrected distance of visual acuity (UDVA) was 0,32±0,19, the corrected distance visual acuity (CDVA) was 0,88±0,11. The keratotopograpy revealed significant disorders: corneal topography indexes were outside normal values ― Surface Asymmetry Index (SAI) 1,46±0,64, Surface Regularity Index (SRI) 0,52±0,28. 9 months after the operations, UDVA was 0,83±0,17, CDVA was 0,92±0,08, the safety index was 1,05, the efficacy index was 0,94. There was a significant decrease of corneal surface asymmetry and irregularity: SAI was 0,62±0,19, SRI ― 0,46±0,15. No complications were noted during and after the surgery. The flap was formed without defects in all cases. Thus, topography-guided laser in situ keratomileusis is a safe and effective approach to treating the post-RK refractive disorders.

Key words: radial keratotomy, correction of post-keratotomy refractive disorders, topography-guided laser in situ keratomileusis.
