Novel cross-linking application for low myopia shows promise
MAASTRICHT, Netherlands — Photorefractive intrastromal cross-linking, or PiXL, is a novel treatment option that appears promising for low-grade myopia, according to one speaker here. This new application of corneal cross-linking, developed by Avedro, is performed with the epithelium on under topical anesthesia. Isotonic riboflavin is applied every 90 seconds for 10 minutes, and a circular 4-mm central zone of the cornea is then irradiated with 30 mW/cm2 for 16:40 minutes, resulting in a total UVA dose of 15 J/cm2.
