One example scleral prosthesis (100, 200, 300, 400, 500, 600, 700) includes a first free end and a second free end (102-104, 202-204, 302-304, 402-404, 502-504, 602-604, 702-704), each wider than a middle portion of the scleral prosthesis. Multiple first portions (112a-112b, 208a-208b, 312a-312b, 406a-406b, 506a-506b, 606a-606b, 706a-706b) form the first end of the scleral prosthesis. The first portions are separated along at least half of a length of the scleral prosthesis. Multiple second portions (206a-206b, 310a-310b) may form the second end of the scleral prosthesis, and the second portions may be separated along less than a quarter of the length of the scleral prosthesis. An implantation device (900) can be used to facilitate implantation of a scleral prosthesis. The implantation device includes a first end portion (906) configured to be inserted into a scleral tunnel of an eye. The implantation device also includes a second end portion (902) configured to receive the scleral prosthesis. A rod (912) with a tapered and rounded end can be partially inserted into the first end portion of the implantation device.
