Abstract
Shape and size of the cornea prosthesis takes into account the anatomical conditions, optical strength and existence of a lachrymal film. It comprises thick-edges lens surrounded by two skirts in the form of a circular crown, with an angle of around 30 deg. between them. The material must be gas-permeable, pliable and with refractive index and suitable thickness to give an optical power of around -5D. At least one of the skirts is perforatable and pliable.
