    The clinical results were analyzed of functional rehabilitation technology in patient with posttraumatic corneal opacity combined with irregular astigmatism and pseudophakia by «transepithelial topoguided PRK». The uncorrected visual acuity 9 months postoperatively was 0.8 compared to 0.1 pre-operatively and best-corrected visual acuity was 0.9 compared to 0.6 pre-operatively. The central corneal thickness was 479 postoperatively compared to 556 preoperatively. Keratotopographic indexes SAI (Surface Asymmetry Index) and SRI (Surface Regularity Index) showed recovering of corneal regularity (0.32 and 0.45 postoperatively compared to 0.85 and 1.39 preoperatively, respectively). No regression of refractive result occurred 6 month after surgery.

    Key words: transepithelial photorefractive keratectomy, topography-guided ablation, posttraumatic corneal opacity, irregular astigmatism.
