Simultaneous TransPRK and Corneal Collagen Cross-Linking

Aberrometry or topography guided transepithelial photorefractive keratectomy (TransPRK) using the Schwind Amaris 750s excimer laser (www.eye-tech-solutions.com), an 8mm treatment diameter, and a tissue saving algorithm targeting selected higher order aberrations only. TransPRK will be followed immediately by corneal collagen cross-linking (CXL).

"Riboflavin soak: 10 minutes total soak time; application of 0.1% riboflavin preparation (VibeX Rapid - www.avedro.com) each 2 minutes with gentle balanced salt solution irrigation to remove excess riboflavin prior to UV light exposure.~UV light exposure: Total treatment time 8 minutes (370nm wavelength; 30mW/cm2 irradiance; 4 minutes total UV exposure time, pulsed 1.5 seconds on 1.5 seconds off; Avedro KXL I light source)"
