What is the different types of surgical procedure for glaucoma's patient

The three types most frequently used are:

Trabeculoplasty—This procedure is most often used to treat open-angle glaucoma. Using the laser, the surgeon will make many small microscopic burns in the drainage area of the eye. This will allow the aqueous fluid to drain more freely. The procedure takes 10-20 minutes, and you can resume normal activities right after it. It takes about 2-3 weeks before one can see the maximum effect from the surgery.

Iridotomy—This surgery is frequently used to treat angle-closure glaucoma or to prevent it in patients who have very narrow drainage angles. Using the laser, the surgeon will make a small hole in the iris. This will allow the aqueous fluid to flow more freely inside the eye and help to widen the drainage angle between the cornea and iris.

Cyclophotocoagulation—This procedure is usually reserved for more advanced or aggressive cases of glaucoma that are refractory to other treatments. Using either the laser or a freezing probe, the surgeon will destroy selected areas of the ciliary body—the part of the eye that produces fluid. This will reduce the production of aqueous fluid.
