A scleral prosthesis includes a prosthesis body having first and second side surfaces and a cavity extending through the prosthesis body from the first side surface to the second side surface. The scleral prosthesis also includes a crossbar configured to be inserted into the cavity, where the crossbar is wider than the prosthesis body. The cavity could define a narrower central opening and wider end openings, and the crossbar could have a narrower central portion and wider end portions. Also, the prosthesis body could include multiple cavities, and the scleral prosthesis could include multiple crossbars configured to be inserted into the multiple cavities. Each of the cavities could be located proximate to an end of the prosthesis body. The crossbar could be substantially straight with a cylindrical cross section.
