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.
Claims20
A light energy delivery system comprising:
- a console comprising a power supply and control electronics;
- and
- a handpiece coupled to the console, the handpiece configured to produce light energy based on power and control signals provided by the console;
- wherein the handpiece includes a removable tip having a shielding extension configured to be inserted posterior to an eyelid between the ocular conjunctiva and palpebral conjunctiva;
- and
- wherein the shielding extension is comprised of a thermally insulative material such that energy not absorbed by a target tissue is prevented from reaching ocular tissue located posterior to the eyelid.
A removable tip for a light energy handpiece, the removable tip comprising:
- a hollow conduit/cavity configured to surround a light guide in the handpiece;
- a support extension having a length longer than a length of the hollow conduit/cavity;
- and
- a shielding extension coupled to the support extension at an angle less than 180 degrees and located distal to the hollow conduit;
- and
- the shielding extension configured to be inserted behind an eyelid and extend to the fornix, the shielding extension comprised of a thermally insulative material.
A method of protecting ocular tissue during application of light energy, the method comprising:
- attaching a removable tip to a handpiece of an light energy device, the removable tip having a shielding extension configured to be inserted behind an eyelid and comprised of a thermally insulative material;
- and
- inserting the shielding extension behind the eyelid to the fornix prior to applying light energy to an anterior surface of the eyelid.
