Glaucoma

Glaucoma is a condition of increased intraocular pressure because of obstructed aqueous humor outflow.

Possible instruments and equipment needed for the procedure include a basic eye set, an operating microscope, and a shunt.

A brief description of the procedure follows:

1. A Lancaster speculum is placed to retract the eyelids.

2. A Beaver knife handle with blade is used to incise the conjunctiva.

3. A Jameson muscle hook is used to isolate the rectus muscles.

4. The device plate is sutured to the sclera using the Barraquer needle holder and Kelman-McPherson tying forceps.

5. A Kelly-Descemet membrane punch is used to create a tunnel into the anterior chamber.

6. The device tube is inserted into the anterior chamber and anchored with suture.
