Treatment of fatty tissue adjacent an eye
The appearance of a sagging eyelid can be altered. A surface of a target region of skin of the eyelid is cooled, and a beam of radiation is delivered to the target region to affect at least one fat cell of the fatty deposit to alter the appearance of the sagging eyelid without causing substantial unwanted injury to tissue surrounding the target region of skin.
1 . A method of altering the appearance of a sagging eyelid, comprising:
cooling a surface of a target region of skin causing the sagging eyelid; and
delivering a beam of radiation to the target region to affect at least one fat cell of a fatty deposit to alter the appearance of the sagging eyelid without causing substantial unwanted injury to tissue surrounding the target region.
2 . The method of claim 1 further comprising causing the fatty deposit of the eyelid to be reduced in size.
3 . The method of claim 1 further comprising damaging the at least one fat cell so that lipid contained within can escape and at least a portion of the lipid can be carried away from the tissue.
4 . The method of claim 1 further comprising destroying the at least one fat cell.
5 . The method of claim 1 further comprising delivering the beam of radiation to the target region to thermally injure the at least one fat cell.
6 . The method of claim 1 further comprising reducing discoloration of skin of the target region.
7 . The method of claim 1 further comprising inducing collagen formation in the target region of skin to improve skin laxity.
8 . The method of claim 1 further comprising delivering the beam of radiation to the target region about 0.1 mm to about 3 mm below the exposed surface of the skin.
9 . The method of claim 1 further comprising focusing the beam of radiation below the surface of the skin in the target region to affect the at least one fat cell.
10 . The method of claim 9 further comprising focusing the beam of radiation using a planoconvex lens.
11 . The method of claim 9 further comprising:
providing a lens with a concave contact surface; and
applying vacuum to draw the target region of skin against the concave contact surface of the lens to focus the beam of radiation to the at least one fat cell in the target region.
12 . An apparatus for altering the appearance of a sagging eyelid, comprising:
a source generating a beam of radiation, the source including a fiber coupled laser diode array;
a delivery system coupled to the source for directing the beam of radiation to a target region of skin to affect at least one fat cell of a fatty deposit to alter the appearance of the sagging eyelid; and
a cooling system for cooling a surface of the target region of skin to minimize unwanted injury to tissue surrounding the target region.
13 . The apparatus of claim 12 wherein the beam of radiation improves the appearance of the fatty deposit of the eyelid.
14 . The apparatus of claim 12 wherein the beam of radiation causes the fatty deposit of the eyelid to be reduced in size.
15 . The apparatus of claim 12 wherein the delivery system directs the beam of radiation to the target region about 0.1 mm to about 3 mm below the surface of the skin.
16 . The apparatus of claim 12 wherein the fiber coupled laser diode array generates a beam of radiation having at least one wavelength of about 1,208 nm, 1,270 nm, 1,310 nm, 1,450 nm, 1,550 nm, 1,720 nm, 1750 nm, 1,930 nm, and 2,100 nm.
17 . The apparatus of claim 12 further comprising a focusing system to focus the beam of radiation below the surface of the skin to the fatty deposit in the target region to affect the at least one fat cell.
18 . The apparatus of claim 17 wherein the focusing system comprises a planoconvex lens to focus the beam of radiation.
19 . The apparatus of claim 17 wherein the focusing system comprises a plurality of lens to focus the beam of radiation.
20 . The apparatus of claim 17 further comprising a vacuum system and wherein the focusing system comprises a lens with a concave surface to contact the surface of the skin, vacuum being applied to draw the target region of skin against the concave surface of the lens so that the lens focuses the beam of radiation to the at least one fat cell in the target region.
21 . The apparatus of claim 17 wherein the focusing system directs the beam of radiation to the target region about 0.1 mm to about 3 mm below the surface of the skin.
22 . The apparatus of claim 12 wherein the fiber coupled laser diode array comprises a high power semiconductor laser.
23 . An apparatus for altering the appearance of a sagging eyelid, comprising:
means for cooling a surface of a target region of skin causing the sagging eyelid; and
means for delivering a beam of radiation to the target region to affect at least one fat cell of a fatty deposit to alter the appearance of the sagging eyelid without causing substantial unwanted injury to tissue surrounding the target region.
