Methods for treating eye conditions
View Patent ↗Architectures and techniques for treating conditions of the eye, such as presbyopia, utilize sources of treatment energy, such as electromagnetic energy emitting devices, to implement non-corneal manipulations. According to these devices and methods, the sources of treatment energy are activated to direct energy onto parts of the eye, such as the conjunctiva and sclera, to treat presbyopia. The treatments can affect at least one property of the eye and enhance an accommodation of the eye.
1. A method for treating an eye in need of one or more of a physiological and a vision correction, comprising:
applying a force to a portion of a conjunctiva of the eye in a clockwise direction, the portion receiving the force changing relative to the sclera from a first configuration to a second configuration;
projecting a pattern of electromagnetic energy onto the conjunctiva in the form of a spot or a radial line;
directing electromagnetic energy toward the pattern and into the sclera;
applying a force to the portion of the conjunctiva in a counter-clockwise direction, the portion receiving the force changing relative to the sclera from the second configuration to another configuration;
further applying a force to the portion of the conjunctiva, the portion receiving the force changing relative to the sclera from the other configuration to a third configuration;
projecting a pattern of electromagnetic energy onto the conjunctiva in the form of a spot or a radial line; and
directing electromagnetic energy toward the pattern and into the sclera.
2. The method as set forth in claim 1 , wherein the further applying of a force comprises further applying a force to the portion of the conjunctiva in the counter-clockwise direction about the center of the eye.
3. The method as set forth in claim 2 , wherein the directing comprises ablating the sclera.
4. The method as set forth in claim 2 , wherein:
the projected pattern is a spot; and
the electromagnetic energy is directed onto the sclera in the form of a radial line.
5. The method as set forth in claim 4 , wherein the electromagnetic energy is directed onto the sclera in the form of a set of radial lines.
6. The method as set forth in claim 4 , wherein the directing comprises directing laser energy onto the sclera.
7. The method as set forth in claim 2 , wherein:
the projected pattern is a spot; and
the electromagnetic energy is directed onto the sclera in the form of a plurality of spots.
8. The method as set forth in claim 7 , wherein the electromagnetic energy is directed onto the sclera in the form of a set of radial lines.
9. The method as set forth in claim 7 , wherein the directing comprises directing laser energy onto the sclera.
10. The method as set forth in claim 2 , wherein the last directing step is followed by applying a force to the portion of the conjunctiva in the clockwise direction.
11. The method as set forth in claim 10 , wherein the electromagnetic energy is directed onto the sclera in the form of a set of radial lines.
12. The method as set forth in claim 1 , wherein the further applying of a force comprises further applying a force to the portion of the conjunctiva in the clockwise direction about the center of the eye.
13. The method as set forth in claim 12 , wherein the directing comprises ablating the sclera.
14. The method as set forth in claim 12 , wherein:
the projected pattern is a spot; and
the electromagnetic energy is directed onto the sclera in the form of a radial line.
15. method as set forth in claim 14 , wherein the electromagnetic energy is directed onto the sclera in the form of a set of radial lines.
16. The method as set forth in claim 14 , wherein the directing comprises directing laser energy onto the sclera.
17. The method as set forth in claim 12 , wherein:
the projected pattern is a spot; and
the electromagnetic energy is directed onto the sclera in the form of a plurality of spots.
18. The method as set forth in claim 17 , wherein the electromagnetic energy is directed onto the sclera in the form of a set of radial lines.
19. method as set forth in claim 17 , wherein the directing comprises directing laser energy onto the sclera.
20. The method as set forth in claim 12 , wherein the last directing step is followed by applying a force to the portion of the conjunctiva in the counter-clockwise direction.
21. The method as set forth in claim 20 , wherein each of the directing steps comprises directing the electromagnetic energy onto the sclera in the form of a set of radial lines.
