Before the surgery
It is a prophylactic treatment performed in eyes with a narrow angle (occludable angle) to prevent acute glaucoma episodes (sharp rises in intraocular pressure due to pupillary block).
Surgery consists of making a small hole in the periphery of the iris to connect the posterior and anterior areas of the iris (posterior chamber to anterior chamber) and balance the pressure between them.
