Glaucoma is a disease that is characterized by a particular pattern of progressive damage to the optic nerve that generally begins with a subtle loss of side vision. The type of laser surgery will depend on the form of glaucoma and how serious it is.
During the laser procedure, the eye is numbed so that there is little or no pain. The surgery is generally done with a local anesthetic and relaxing medications. Usually a limited type of anesthesia is used, called intravenous (I.V.) sedation.
Filtering surgery is an outpatient procedure that requires no overnight hospital stay. During days after surgery, the ophthalmologist will make check-up of the eye pressure. The eye doctor will also examine for any signs of infection or increase in inflammation.
At least one week after surgery patients are advised to keep water out of the eyes. You are allowed your own casual life with most of daily activities, however it is important to avoid driving, reading, bending, and doing any heavy lifting.
The eye will be red and irritated after surgery for little time, eye tearing or watering can happen. The inner eye fluid flows through the surgically-created hole and forms a small blister-like bump called a bleb. The bleb, usually located on the upper surface of the eye, is covered by the eyelid, and is usually not visible.
