Scleral prosthesis for treating presbyopia and other eye disorders and related devices and methods
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 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 are wider than the remainder of the body. The first portions are separated by empty space such that the first portions meet at a point between the first and second ends and are not connected to each other between that point and the first end. The first end projects beyond one or more sides of the remainder of the body and angles back towards the second end. The second end projects beyond the one or more sides of the remainder of the body and angles back towards the first end.

wherein the first portions of the body are separated lengthwise along a substantial portion of a total length of the elongated body by empty space such that the multiple 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;
wherein the first end projects beyond one or more sides of the remainder of the body and angles back towards the second end; and
wherein the second end projects beyond the one or more sides of the remainder of the body and angles back towards the first end.
2. The scleral prosthesis of claim 1 , wherein interior angles formed between the first and second ends and the remainder of the body are acute angles.

4. The scleral prosthesis of claim 1 , wherein:
opposite sides of the first end project beyond opposite sides of the remainder of the body and angle back towards the second end; and
opposite sides of the second end project beyond the opposite sides of the remainder of the body and angle back towards the first end.
5. 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.
6. The scleral prosthesis of claim 5 , wherein:
the first portions of the body are separated along at least half of the total length of the body; and
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 second end of the body is integral with the remainder of the body and not divided into multiple separated portions.
8. 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; and
the ridges are configured to engage with slots of an insert.
9. 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.
10. The scleral prosthesis of claim 1 , wherein the body comprises at least one magnetic material.
11. A system comprising:
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;
wherein the first portions of the body are separated lengthwise along a substantial portion of a total length of the elongated body by empty space such that the multiple 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;
wherein the first end projects beyond one or more sides of the remainder of the body and angles back towards the second end; and
wherein the second end projects beyond the one or more sides of the remainder of the body and angles back towards the first end; and
an insert configured to be placed between the first portions of the body.
12. The system of claim 11 , wherein:
opposite sides of the first end project beyond opposite sides of the remainder of the body and angle back towards the second end; and
opposite sides of the second end project beyond the opposite sides of the remainder of the body and angle back towards the first end.
13. The system 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.
14. The system of claim 13 , wherein:
the first portions of the body are separated along at least half of the total length of the body; and
the second portions of the body are separated along less than a quarter of the total length of the body.
15. The system of claim 11 , wherein the second end of the body is integral with the remainder of the body and not divided into multiple separated portions.
16. The system 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; and
the ridges are configured to engage with slots of the insert.
17. The system of claim 11 , 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.
18. The system of claim 11 , wherein the insert tapers from a first larger width configured to be placed adjacent the first end to a smaller width and then expands to a second larger width configured to be placed adjacent the point where the first portions of the body meet.
19. The system of claim 11 , wherein at least one of the body and the insert comprises at least one magnetic material.
20. A method comprising:
obtaining a scleral prosthesis having 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;
wherein the first portions of the body are separated lengthwise along a substantial portion of a total length of the elongated body by empty space such that the multiple 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;
