PRK with cross-linking improves visual acuity in eyes with keratoconus

Topography-guided PRK followed by corneal collagen cross-linking yielded a greater improvement in visual acuity than cross-linking alone in eyes with progressive keratoconus, a study found.“In our opinion, the most significant finding from this study was that with cautious implementation of topography-guided surface ablation, patients with keratoconus can be significantly benefited without compromising the stabilization effect of CXL,” Georgios A. Kontadakis, MD, the corresponding author, told Ocular Surgery News. “While planning this procedure and performing it, it is crucial to address safety precautions at all times. The other original finding of our study was the more potent effect of the combined procedure in comparison to CXL alone, as seen in confocal microscopy. The biomechanical consequence remains to be clarified, even though clinically it was similar in both our groups.”
