Excision of the anterior layers of the cornea can be accomplished with comparative safety when the eye is free from inflammation. It is a satisfactory method for removal of unsightly leukomas, multiple foreign bodies superficially buried, pseudopterygium, painful corneal scars that frequently break down and result in recurrent ulcers and degenerating anterior layers of cornea in certain types of dystrophy. The results of the operation are frequently gratifying from the visual and cosmetic standpoints. The cornea, however, always remains partly cloudy after the excision of the anterior layers, and visual acuity, at best, is impaired.

New corneal epithelium grows rapidly. After excision of the anterior layers to within 2 mm. of the limbus, the entire cornea will be recovered with epithelium in from four to seven days. Regeneration of the substantia propria occurs much more slowly, but under favorable conditions excised tissue may be entirely replaced. In an eye that
