Scleral prosthesis for treating presbyopia and other eye disorders and related devices and methods
A system includes a scleral prosthesis and an insert. The scleral prosthesis includes an elongated body having a first free end and a second free end opposite the first end. A maximum width of the body at each end is wider than a maximum width of the body between the ends. The body includes multiple first portions that form the first end of the body and a part of the body between the ends. The first portions are separated lengthwise along a substantial portion of a total length of the body. The first portions are biased so that they maintain separation from one another without external interference but are configured to be pushed towards each other. The insert is configured to be placed between the first portions to maintain a separation of the first portions. The body and/or the insert could be formed using one or more magnetic materials.
1. An ocular system comprising:
a scleral prosthesis configured to be implanted into scleral tissue of an eye, the scleral prosthesis comprising:
an elongated body having a first free end and a second free end opposite the first end, a maximum width of the body at each end wider than a maximum width of the body between the ends;
wherein the body comprises multiple first portions that form the first end of the body and a part of the body between the ends, the first portions separated by empty space lengthwise along a substantial portion of a total length of the body from the first free end to the second free end;
wherein the first portions run substantially parallel to one another along the body;
wherein the first portions meet at a point between the ends of the body and are not connected to each other between that point and the first end of the body; and
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; and
an insert configured to be placed between the first portions of the body to maintain a separation of the first portions, the insert having a complementary shape and length as the empty space between the first portions.
2. The ocular system of claim 1 , wherein at least one of the body and the insert comprises one or more magnetic materials.
3. The ocular system of claim 1 , wherein each of the body and the insert comprises one or more magnetic materials.
4. The ocular system of claim 1 , wherein the body and the insert are magnetically attracted.
5. The ocular system of claim 1 , wherein the insert comprises a wider end portion that fits within a space proximate to a location where the first portions of the body meet.
6. The ocular system of claim 1 , wherein the first portions are separated along at least half of the total length of the body.
7. The ocular system of claim 1 , wherein the body further comprises multiple second portions that form the second end of the body and another part of the body between the ends, the second portions separated lengthwise along the body.
8. The ocular system of claim 7 , wherein the second portions run substantially parallel to one another along the length of the body.
9. The ocular system of claim 7 , wherein the second portions are separated along less than a quarter of the total length of the body.
10. The ocular system of claim 7 , wherein the second portions meet at a second point between the ends of the body and are not connected to each other between that second point and the second end of the body.
11. The ocular system of claim 1 , wherein each of the first portions includes a ridge extending inwardly from that first portion towards the other first portion of the body, the ridges configured to engage with slots of the insert.
12. A method comprising:
forming an elongated body of a scleral prosthesis, the body configured to be implanted into scleral tissue of an eye, the body having a first free end and a second free end opposite the first end, a maximum width of the body at each end wider than a maximum width of the body between the ends; and
forming an insert for the body;
wherein the body comprises multiple first portions that form the first end of the body and a part of the body between the ends, the first portions separated by empty space lengthwise along a substantial portion of a total length of the body from the first free end to the second free end;
wherein the first portions run substantially parallel to one another along the body;
wherein the first portions meet at a point between the ends of the body and are not connected to each other between that point and the first end of the body;
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; and
wherein the body is configured to receive and retain, between the first portions of the body, the insert to maintain the separation of the first portions, the insert having a complementary shape and length as the empty space between the first portions.
13. An ocular system comprising:
a scleral prosthesis configured to be implanted into scleral tissue of an eye, the scleral prosthesis comprising:
an elongated body having a first free end and a second free end opposite the first end, a maximum width of the body at each end wider than a maximum width of the body between the ends;
wherein the body comprises multiple first portions that form the first end of the body and a part of the body between the ends, the first portions separated by empty space lengthwise along a substantial portion of a total length of the body from the first free end to the second free end;
wherein the first portions run substantially parallel to one another along the body;
wherein the first portions meet at a point between the ends of the body and are not connected to each other between that point and the first end of the body; and
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; and
an insert configured to be placed between the first portions of the body to maintain a separation of the first portions, the insert having a shape that at least substantially fills the empty space between the first portions.
14. The ocular system of claim 13 , wherein at least one of the body and the insert comprises one or more magnetic materials.
15. The ocular system of claim 13 , wherein each of the body and the insert comprises one or more magnetic materials.
16. The ocular system of claim 13 , wherein the body and the insert are magnetically attracted.
17. The ocular system of claim 13 , wherein the insert comprises a wider end portion that fits within a space proximate to a location where the first portions of the body meet.
18. The ocular system of claim 13 , wherein the body further comprises multiple second portions that form the second end of the body and another part of the body between the ends, the second portions separated lengthwise along the body.
19. The ocular system of claim 18 , wherein the second portions run substantially parallel to one another along the length of the body.
20. The ocular system of claim 18 , wherein:
the first portions are separated along at least half of the total length of the body; and
the second portions are separated along less than a quarter of the total length of the body.
