Tear Fluid Cellular Fibronectin Levels After Photorefractive Keratectomy

Abstract

There is a rapid increase in excretion of EDAcFn in tears following PRK. This seems to last only as long as an epithelial defect persists. The epithelium of all eyes healed in 3 to 4 days in spite of wide interindividual variations in both tear fluid flow and EDAcFn excretion.
