Stellate corneal epithelial iron line after radial keratotomy (RK)

Contributor: Jesse Vislisel, MD

Photographer: Stefani Karakas, CRA

This photograph shows the radially oriented corneal incisions from prior radial keratotomy (RK) with a characteristic central stellate corneal epithelial iron line. The Prospective Evaluation of Radial Keratotomy (PERK) study found that these iron lines occur in 78-85% of eyes after RK depending on the duration that has elapsed since their surgery. The iron lines are not visually significant.
