Continued research on plastic prostheses for the canine eye in the Department of Veterinary Medicine at Iowa State College has resulted in the development of an intrascleral prosthesis, which, from the limited application thus far, shows great promise. The form and shape of the previously reported prostheses1 has been changed considerably. These changes, for the most part, have been aimed at providing more positive attachment for the ocular muscles and giving a better cosmetic effect.
