Scleral Lens–Induced Corneal Edema After Radial Keratotomy

This case series examines the magnitude and regional variation in scleral lens–induced corneal edema postradial keratotomy (RK) eyes. Scheimpflug imaging was used to measure thickness across central 6 mm before after lens wear nine post-RK eyes (median age 64 years). Variations were examined as a function of distance from center (six 0.5-mm annuli) 0° 360°. The median 2.19% (interquartile range 1.03%–3.18%; P=0.02) increased variability further cornea (from 1.30% 0–0.5 3.12% 2.5–3.0 midperiphery) (P=0.02). Scleral greater at approximate location incisions.
