Abstract
A removable tip for a light energy handpiece comprises a hollow conduit configured to surround a light guide in the handpiece; a support extension having a length longer than a length of the hollow conduit; and a shielding extension coupled to the support extension at an angle less than 180 degrees and located in front of the hollow conduit. The shielding extension is configured to be inserted behind an eyelid and extend to the fornix, the shielding extension comprised of a thermally insulative material.
Claims19
A method of protecting ocular tissue during application of light energy, the method comprising:
- providing a handpiece having a light energy device, the handpiece having a tip having a shielding extension configured to be inserted posterior to an eyelid;
- inserting the shielding extension behind the eyelid prior to applying light energy to the eyelid;
- applying light energy from the light energy device to the eyelid;
- wherein the light energy device comprises an LED;
- and
- wherein the shielding extension is comprised of a sufficiently thermally insulative material such that heat from a target tissue is prevented from reaching ocular tissue located posterior to the eyelid in a quantity that would damage the ocular tissue.
A method of protecting ocular tissue during application of light energy, the method comprising:
- providing a handpiece having a light energy device, the handpiece having a tip having a shielding extension configured to be inserted posterior to an eyelid;
- inserting the shielding extension behind the eyelid prior to applying light energy to the eyelid;
- applying light energy from the light energy device to the eyelid;
- wherein the light energy device comprises an LED;
- and
- wherein the shielding extension comprises at least two layers;
- wherein a first layer is a proximal layer to the handpiece and the second layer is a distal layer of the shielding extension;
- and
- wherein the distal layer is configured to be in direct contact with posterior organs to be protected and the proximal layer is configured to be in contact with the eyelid;
- wherein the distal layer is configured to insulate the posterior organs from heat energy and the proximal layer is configured to conduct heat away from the posterior organs.
A method of protecting ocular tissue during application of light energy, the method comprising:
- providing a handpiece having a light energy device, the handpiece having a tip having a shielding extension configured to be inserted posterior to an eyelid;
- inserting the shielding extension behind the eyelid prior to applying light energy to the eyelid;
- applying light energy from the light energy device to the eyelid;
- wherein the light energy device comprises an LED;
- and
- wherein the handpiece further comprises a heat sink thermally coupled to the shielding extension.
