A protocol for topographic-guided corneal repair utilizing the US Food and Drug Administration-approved Wavelight Contoura
Abstract
Manoj Motwani Motwani LASIK Institute, San Diego, CA, USA Purpose: To demonstrate how Wavelight Contoura can be used to repair corneas damaged by trauma and prior poor surgical outcomes. Methods: Four representative eyes are presented that show different scenarios in which highly irregular corneas can be corrected with Wavelight Contoura using a protocol (named the San Diego Protocol) designed to use the information in Contoura processing. Both laser-assisted in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) were used. Results: Highly aberrant corneas with large amounts of warpage can be corrected safely with the Wavelight Contoura system. The San Diego Protocol requires individual analysis of each case with decisions based on the level of warpage and the level of epithelial hyperplastic compensation. The need for a second refractive power equalization procedure should be planned for. Conclusion: Contoura measured refraction can be integrally used as part of the San Diego Protocol to safely repair highly warped corneas. The refractive outcomes show dramatic improvement in vision, best-corrected visual acuity (BCVA), refraction, and topographic uniformity.
