CyPass® Micro-Stent is a way to manage glaucoma at the same time you undergo cataract surgery. It is a very small plastic tube placed just below the surface of the eye to help reduce eye pressure.

This is a way to increase the existing outflow of fluid in your eye by keeping one of the eye’s drainage pathways open. Now that the fluid has a place to go and isn’t building up, the pressure inside your eye (intraocular pressure) is reduced.

More than 500 people were included in a large clinical study of CyPass® Micro-Stent. In this study, 374 patients had CyPass® Micro-Stent placed in one eye immediately after their cataract surgery, while 131 had only cataract surgery.

Understanding glaucoma

Glaucoma is a disease that causes damage to
the eye’s optic nerve. As with many diseases, the symptoms of glaucoma can be subtle at first, such as a slight loss of peripheral vision (side vision). However, if left untreated, glaucoma may lead to vision loss that gets worse over time. Once vision is lost, you can’t get it back.

Eye pressure and glaucoma

Your eyes are constantly producing fluid. This fluid provides nourishment to the eye and is essential for normal eye function. As fluid is produced, it moves throughout your eye and eventually exits through tiny drainage channels located near the cornea (the front part of your eye). If these drainage channels become blocked, the fluid in your eye can build up, causing elevated eye pressure (also called intraocular pressure or “IOP”). This elevated eye pressure can damage your optic nerve.
A common goal of glaucoma treatment is to reduce this pressure. This is where CyPass® Micro-Stent may help.
