Abstract

A method fo performing dacryocystorhinostomy is provided in which the surgeon inserts a video endoscope into a punctum, through the associated canaliculus and into the lacrimal sac. The surgeon passes a bone cutting laser, connected to a fiber optic bundle, through the other punctum, through the associated canaliculus and into the lacrimal sac. The laser is illuminated through the fiber optic bundle and visualized through the video endoscope. The laser is properly positioned sometime with the help of a transnasal videoendoscope to confirm optimal position relative to nasal structure. The laser is then activated so as to form a full thickness tear draining fistula through the sac and the nasal bone. A tube or stent may be placed to keep the fistula patent or from closure.

Claims

1. A method for performing ophthalmological surgery comprising the steps of:

making a first punctum through the upper eyelid margin to attain access to a first canaliculus;

passing a video endoscope through the first punctum and through the first canaliculus;

passing said video endoscope into a lacrimal sac;

making a second punctum through the lower eyelid margin to attain access to a second canaliculus;

passing a bone cutting laser through the second punctum and through the second canaliculus;

passing said bone cutting laser into said lacrimal sac;

visualizing said laser through said video endoscope;

positioning said laser towards an inferior turbinae bone;

activating said laser; and

forming a full thickness fistula through said lacrimal sac and through said inferior turbinate bone.

2. The method of claim 1 further using the translacrimal laser to remove dacryoliths or perforate a soft tissue obstruction in the nasolacrimal duct to achieve normal drainage.

3. The method of claim 1 wherein the step of passing a video endoscope through a first punctum and through a first canaliculus further comprises a step of passing a FVS 1000 video endoscope through a first punctum and through a first canaliculus.

4. The method of claim 1 wherein said step of passing a laser through a second punctum and through a second canaliculus further comprises the step of passing a laser which has been connected to a fiber optic bundle through a second punctum and through a second canaliculus.

5. The method of claim 1 wherein said laser is a YAG laser.

6. The method of claim 1 further using the translacrimal laser to revise a failed DCR.

7. The method of claim 1 wherein said laser is a Holmium laser.

8. The method of claim 3 wherein said step of visualizing said laser through said video endoscope further comprises the step of illuminating said laser through said fiber optic bundle.

9. A method of performing a translacrimal laser dacryocystorhinostomy comprising the steps of:

creating a first punctum in the upper eyelid margin to attain access to the canaliculus;

passing a video endoscope through the first punctum;

passing said video endoscope through the first canaliculus;

passing said video endoscope into the lacrimal sac;

creating a second punctum through the lower eyelid margin to attain access to the second canaliculus;

passing a bone cutting laser through the second canaliculus;

passing said bone cutting laser into said lacrimal sac;

illuminating said laser through a fiber optic bundle;

visualizing said laser through said video endoscope;

positioning said laser towards an inferior turbinate bone;

activating said laser;

forming a full thickness fistula through said lacrimal sac and through said inferior turbinate bone.

10. The method of claim 9 wherein said laser is a YAG laser.

11. The method of claim 9 wherein said laser is a Homium laser.

12. The method of claim 9 further including the step of placing a stent in said full thickness fistual.
