We also perform a specialized version of PRK called Transepithelial PRK. This procedure utilizes corneal epithelial thickness mapping to determine how much epithelial compensation is present for corneal higher-order aberrations/irregularity. We use this data to guide epithelial removal by an excimer laser. Then, we use Contoura topographic-guided ablation to create a virtually perfect, uniform cornea. We can use this method in corneal reconstructive repairs of past surgical procedures, disease, and trauma as significant epithelial compensation can occur and mask the true extent of the corneal irregularity.
Dr. Motwani uses Trans-Epithelial PRK with his LYRA Protocol to create a virtually perfect cornea for the best possible vision. Dr. Motwani requested to have this procedure performed on himself as part of his research work, being the first to undergo the CREATE Protocol (Corneal Repair Epithelium and Topography Enhanced). This protocol has also been granted a patent by the United States Patent Office (European Patents Pending).
