Apparatus and method for treatment of dry eyes
A disposable/removable tip attachable on a distal end of a fiber bundle, allowing transmitting light energy from the fiber bundle to an eyelid and comprising a contact surface made of bio-compatible material, which allows to contact the eyelid and in addition an add-on device, comprising a fiber bundle, having a distal and proximal end, wherein a disposable/removable tip is attachable to the distal end, while the proximal end is connected to an optical coupler, designed for optical and/or energy coupling with a lightguide of a Meibomian gland expression (MGX) treatment device.
1. A method of treating ocular tissue by application of energy for treating dry eye, the method comprising:
providing an energy generating device, the device comprising:
(i) a tip, the tip being generally U-shaped and having two portions, one portion being configured to be inserted anterior to an eyelid, the other portion being configured to be inserted posterior to an eyelid,
(ii) an energy element configured to provide energy to the anterior portion and to the anterior of the eyelid, and
(iii) a highly reflective layer within the posterior portion of the tip and configured to reflect energy back to the posterior surface of the eyelid;
inserting the U-shaped tip anteriorly and posteriorly of the eyelid prior to applying energy to the anterior portion of the eyelid; and,
applying energy from the energy element directly to the anterior portion of the eyelid and by reflection to the posterior surface of the eyelid.
2. The method of claim 1 , wherein a shielding extension is provided on on the posterior portion of the tip 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.
3. The method of claim 1 , wherein the U-shaped tip extension is configured to be inserted posterior to an eyelid between the ocular conjunctiva and palpebral conjunctiva.
4. The method of claim 1 , wherein the tip is a removable tip.
5. The method of claim 1 , wherein the energy generating device is a light energy generating device.
6. The method of claim 5 , wherein the light energy device is one or more of: LED energy or IPL.
7. The method of claim 1 , wherein the energy device is one or more of: RF energy or ultrasonic energy.
8. A method of treating ocular tissue during application of energy for treating dry eye, the method comprising:
providing an energy generating device, the device further comprising:
(i) a tip, the tip being generally U-shaped, and being configured to be inserted both anterior and posterior to an eyelid,
(ii) an energy elements on the tip and being configured to provide energy directly to both the anterior and to the posterior of the eyelid, and
inserting the tip anteriorly and posteriorly of the eyelid prior to applying energy to one or more of the anterior and posterior surfaces of the eyelid; and,
applying energy from the energy device directly to the anterior and to the posterior surfaces of the eyelid.
9. The method of claim 8 , wherein a shielding extension is provided on the posterior portion of the tip and 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.
10. The method of claim 1 , wherein the energy generating device further comprises a shaft having a distal end portion;
the shaft being movable being movable toward and away from the anterior of the eyelid;
the energy generating device being mounted on the distal end portion of the shaft;
the method comprising the steps of:
moving the shaft distally to contact the anterior of the eyelid;
activating the energy-generating device to provide energy to the anterior of the eyelid; and,
moving the shaft further distally to apply pressure to the eyelid positioned between the distal portion of the shaft and the tip portion posterior of the eyelid.
11. The method of claim 8 , wherein the energy generating device further comprises a shaft having a distal end portion;
the shaft being movable being movable toward and away from the anterior of the eyelid;
the energy generating device being mounted on the distal end portion of the shaft;
the method comprising the steps of:
moving the shaft distally to contact the anterior of the eyelid;
activating the energy-generating device to provide energy to the anterior and to the posterior of the eyelid; and,
moving the shaft further distally to apply pressure to the eyelid positioned between the distal portion of the shaft and the tip portion posterior of the eyelid.
