A scleral shell is an ocular prosthesis that is worn over an existing eye. Typically, one who is a candidate for a scleral shell has a blind phthisical eye. The shell fits like a large contact lens, covering the whole front surface of the eye globe. It moves along with the existing eye and is fit so that the eyelid opening are symmetrical. The process of making a scleral shell is very similar to the making of an artificial eye, with a few extra steps to ensure comfort over the existing cornea. |
