A scleral prosthesis includes an elongated body configured to be implanted into scleral tissue of an eye. The elongated body includes (i) opposing first and second ends and (ii) multiple first portions that form the first end of the body and part of a remainder of the body between the ends. The first and second ends are wider than the remainder of the body. The first portions of the body are separated lengthwise along the body by empty space such that the first portions meet at a point between the first and second ends of the body and are not connected to each other between that point and the first end. The scleral prosthesis also includes an insert configured to be placed and retained between the first portions of the body. The insert has a length that is at least about half of a length of the elongated body.

1. A scleral prosthesis comprising: an elongated body configured to be implanted into scleral tissue of an eye, the elongated body comprising (i) opposing first and second free ends and (ii) multiple first portions that form the first end of the body and part of a remainder of the body between the first and second ends, the first and second ends wider than the remainder of the body, the first portions of the body separated lengthwise along at least about half of a total length of the body by empty space such that the first portions meet at a point between the first and second ends of the body and are not connected to each other between that point and the first end of the body; andan insert configured to be placed and retained between the first portions of the body, wherein the insert has a length that is at least about half of the total length of the elongated body;wherein at least a portion of the insert comprises a shape complementary to a shape of the empty space; andwherein the insert is configured to be inserted lengthwise into the empty space. 2. The scleral prosthesis of claim 1, wherein: the insert is configured, when inserted between the first portions of the body, to extend from the first end of the body beyond a midpoint of the body between the first and second ends. 3. The scleral prosthesis of claim 1, wherein: the first portions of the body are biased so that they maintain separation from one another without external interference but are configured to be pushed towards each other; andthe insert is configured, after insertion between the first portions of the body, to maintain the separation of the first portions of the body. 4. The scleral prosthesis of claim 1, wherein the body further comprises multiple second portions that form the second end of the body and another part of the remainder of the body. 5. The scleral prosthesis of claim 4, wherein: the first portions of the body run substantially parallel to one another along the length of the body; andthe second portions of the body run substantially parallel to one another along the length of the body. 6. The scleral prosthesis of claim 4, wherein the second portions of the body are separated along less than a quarter of the total length of the body. 7. The scleral prosthesis of claim 1, wherein: the first portions of the body include a right first portion and a left first portion;the right first portion includes a first ridge extending inwardly from the right first portion towards the left first portion;the left first portion includes a second ridge extending inwardly from the left first portion towards the right first portion; andthe ridges are configured to engage with slots of the insert. 8. The scleral prosthesis of claim 1, wherein the empty space tapers from a first larger width adjacent the first end to a smaller width and then expands to a second larger width adjacent the point where the first portions of the body meet. 9. The scleral prosthesis of claim 1, wherein the insert tapers from a first larger width at one end of the insert to a smaller width and then expands to a second larger width at another end of the insert. 10. The scleral prosthesis of claim 1, wherein at least one of the body and the insert comprises at least one magnetic material. 11. A method comprising: obtaining an elongated body of a scleral prosthesis configured to be implanted into scleral tissue of an eye, the elongated body comprising (i) opposing first and second free ends and (ii) multiple first portions that form the first end of the body and part of a remainder of the body between the first and second ends, the first and second ends wider than the remainder of the body, the first portions of the body separated lengthwise along at least about half of a total length of the body by empty space such that the first portions meet at a point between the first and second ends of the body and are not connected to each other between that point and the first end of the body; andplacing an insert between the first portions of the body, wherein the insert has a length that is at least about half of the total length of the elongated body;wherein at least a portion of the insert comprises a shape complementary to a shape of the empty space; andwherein the insert is configured to be inserted lengthwise into the empty space. 12. The method of claim 11, wherein the insert, when inserted between the first portions of the body, extends from the first end of the body beyond a midpoint of the body between the first and second ends. 13. The method of claim 11, wherein: the first portions of the body are biased so that they maintain separation from one another without external interference but are configured to be pushed towards each other; andthe insert is configured, after insertion between the first portions of the body, to maintain the separation of the first portions of the body. 14. The method of claim 11, wherein the body further comprises multiple second portions that form the second end of the body and another part of the remainder of the body. 15. The method of claim 14, wherein: the first portions of the body run substantially parallel to one another along the length of the body; andthe second portions of the body run substantially parallel to one another along the length of the body. 16. The method of claim 14, wherein the second portions of the body are separated along less than a quarter of the total length of the body. 17. The method of claim 11, wherein: the first portions of the body include a right first portion and a left first portion;the right first portion includes a first ridge extending inwardly from the right first portion towards the left first portion;the left first portion includes a second ridge extending inwardly from the left first portion towards the right first portion; andthe ridges are configured to engage with slots of the insert. 18. The method of claim 11, wherein the insert tapers from a first larger width at one end of the insert to a smaller width and then expands to a second larger width at another end of the insert. 19. The method of claim 11, wherein at least one of the body and the insert comprises at least one magnetic material. 20. A method comprising: forming an elongated body of a scleral prosthesis configured to be implanted into scleral tissue of an eye, the elongated body comprising (i) opposing first and second free ends and (ii) multiple first portions that form the first end of the body and part of a remainder of the body between the first and second ends, the first and second ends wider than the remainder of the body, the first portions of the body separated lengthwise along at least about half of a total length of the body by empty space such that the first portions meet at a point between the first and second ends of the body and are not connected to each other between that point and the first end of the body; andforming an insert configured to be placed and retained between the first portions of the body, wherein the insert has a length that is at least about half of the total length of the elongated body;wherein at least a portion of the insert comprises a shape complementary to a shape of the empty space; andwherein the insert is configured to be inserted lengthwise into the empty space.
