Treatment of Corneal Irregularity in Radial/Astigmatic Keratotomy Patients Utilizing WaveLight Contoura

Abstract

Purpose: To demonstrate the treatment of radial keratotomy-induced corneal irregularity with topographic-guided ablation (WaveLight Contoura). Methods: Thirty-two eyes of 18 patients were treated for corneal irregularity post-radial keratotomy with WaveLight Contoura topographic-guided ablation utilizing LASIK and PRK and the San Diego Protocol for reconstructing corneas. These eyes were followed for six-months. Outcomes included: measurements of vision, refraction, residual higher-order aberrations, residual lower-order and higher-order aberrations, as well as loss or gains of lines of best-corrected visual acuity. Results: All eyes had decreased corneal irregularity as evidenced by topographic analysis and reduction in manifest astigmatism, Contoura-measured astigmatism, higher-order aberrations, and higher-order aberrations grouped with lower-order aberrations excluding tilt (Grouped). The eyes of 5 sample patients are included in this manuscript to demonstrate the procedure, protocol, and outcomes. Conclusion: Treatment with WaveLight Contoura whether as LASIK or PRK appears to be an effective treatment for corneal irregularity associated with radial/astigmatic keratotomy.
