Topograhy guided photo ablation for the correction of irregular astigmatism following laser in situ keratomileusis

ABSTRACT

To study the safety, efficacy and predictability of topography guided laser in situ keratomileusis [LASIK] to correct irregular astigmatism following previous LASIK surgery resulting from flap melting or decentered ablation. A series of case reports including three eyes of three patients were enrolled in this study. Significant reduction of the irregular astigmatism associated with improvement of the visual acuity was significantly observed following topography guided ablation in these eyes. Topography assisted photo ablation safely and effectively corrected post LASIK astigmatism resulting from melted or decentered flaps
