Superficial calcification was produced in the normal rabbit cornea by mild irradiation with a carbon dioxide laser. The calcification was entirely extracellular and closely resemnbled that observed in human band keratopathy, which was characterized as hydroxyapatite by x-ray diffraction. The electron-mnicroscopic appearance of calcific spheriules and conglomerates in early cornteal calcification is presented. The calcific spherules arise at the basal plasma membrane surface of the epithelial cells in close relation to their basement membrane.
