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:
directing a beam of electromagnetic energy through a conjunctiva, an intersection of the beam and the conjunctiva having a shape of one or more of a spot and a radial line; and
while the beam is directed through the conjunctiva, moving the beam across a surface of a sclera in a pattern of one or more of (a) a plurality of adjacent radial lines and (b) a plurality of substantially parallel lines, wherein the pattern comprises a first line and a second line extending generally along a first direction and a third line extending generally between the first and second lines in a direction other than the first direction.
2. The method as set forth in claim 1 , wherein the pattern comprises a first line and a second line extending generally along a first direction, and a third line extending generally between and connecting the first and second lines.
3. The method as set forth in claim 1 , wherein:
the pattern comprises a first line and a second line extending generally along a first direction; and
a third line contacting the first and second lines and extending generally along a direction other than the first direction.
4. The method as set forth in claim 1 , wherein the pattern comprises a first line and a second line extending generally along a first direction, and a third line extending between the first and second lines in a direction generally transverse to the first direction.
5. The method as set forth in claim 1 , wherein the pattern comprises an “H” shape.
6. The method as set forth in claim 1 , wherein the moving comprises ablating the sclera.
7. The method as set forth in claim 1 , wherein the moving comprises forming a pattern in the sclera that is larger than the shape.
8. The method as set forth in claim 7 , wherein the moving comprises applying a force to change a portion of the conjunctiva, relative to the sclera, from a first configuration to a second configuration.
9. The method as set forth in claim 8 , wherein the moving is followed by applying another force to move at least part of the portion in a direction back toward the first configuration.
10. The method as set forth in claim 1 , wherein the beam is directed through the conjunctiva in a manner so that the intersection of the beam and the conjunctiva has the shape of a spot.
