The most common drainage operation is called a trabeculectomy. The surgery is performed in an operating room
on an out-patient basis. This procedure allows your ophthalmologist to create a new drainage channel for the eye.
Trabeculectomy allows fluid from the eye to flow into a filtering area called a "Bleb". The "Bleb" is mostly
hidden under the eyelid. When successful, this procedure will lower the pressure in your eye minimizing the risk of
vision loss from glaucoma.
