This procedure works well for primary open-angle glaucoma and there are no serious concerns about its safety.
Primary open-angle glaucoma is a worsening condition whereby fluid builds up in the eye causing an increase in pressure. This damages the nerve that connects the eye to the brain (optic nerve) and can lead to loss of sight. In this procedure a tiny tube (stent) is inserted just below the surface of the eye, to create a drainage channel for excess fluid. The procedure is done during surgery for cataracts. The aim is to reduce pressure in the eye.
Is this procedure right for me?
If you’ve been offered this procedure, your healthcare professionals should discuss with you what is involved, and tell you about the risks and benefits. They should talk with you about your options, and listen carefully to your views and concerns. Your family can be involved too, if you wish. All of this should happen before you agree (consent) to have the procedure. You should also be told how to find more information about the procedure. Read more about making decisions about your care.
