Methods and devices for treating presbyopia
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 treatment energy onto an anatomic structure, wherein the treatment energy has a power of about 0,15-0.20 W, a pulse frequency of about 20 Hz, an E pulse of about 8-10 mJ/pulse, an air output from a pressurized air supply line, and a water output from a pressurized water supply line, wherein the treatment energy profile has one or more of a conical and a “V” shape; and
wherein a characteristic or measurable parameter of the treatment energy drops by about 1 to about 20 percent for each 1 percent drop in depth within the anatomic structure.
2. The method as set forth in claim 1 , wherein the treatment energy has a focal point, which is on or in the anatomic structure.
3. The method as set forth in claim 1 , wherein the treatment energy comprises a beam of electromagnetic energy.
4. The method as set forth in claim 1 , wherein the treatment energy is a beam of laser light.
5. The method as set forth in claim 1 , wherein the anatomic structure is located beneath tissue above the anatomic structure, and wherein the anatomic structure, but not the tissue above the anatomic structure, is ablated.
6. The method as set forth in claim 1 , wherein the anatomic structure is a sclera.
7. The method as set forth in claim 1 , wherein the treatment energy is directed through a tip prior to being directed onto the anatomic structure.
8. The method as set forth in claim 1 , wherein:
the treatment energy passes through a tip prior to being directed onto the anatomic structure; and
the tip is held in a non-contact mode to cut or ablate the anatomic structure.
9. The method as set forth in claim 8 , wherein an initial penetration into the anatomic structure is performed with the tip about 1 mm from a surface of the anatomic structure.
10. The method as set forth in claim 8 , wherein the holding of the tip in a non-contact mode is followed by contacting the anatomic structure with the tip to cut or ablate the anatomic structure.
11. The method as set forth in claim 1 , wherein an initial penetration into the anatomic structure is performed in a non-contact, defocused mode followed by further penetration into the anatomic structure in a contact mode.
