What is iStent®?
How does it work?
iStent bypasses these blockages, offering another channel for fluid to drain out of the eye and into the bloodstream, improving the eye’s natural flow and lowering intraocular pressure.
iStent and Cataracts…
iStent surgery and cataract surgery go hand-in-hand, oftentimes being performed at the same time. Once the IOL is placed into the eye following cataract removal, the iStent implant is then inserted through the same incision created for your cataract.
This means that no additional anesthesia or surgical materials are needed and recovery time is not prolonged.
Is iStent right for me?
- Do you have glaucoma?
- Are you currently managing your glaucoma with prescription medication(s)?
- Are you scheduled to have cataract surgery in the near future?

Glaucoma occurs from an overproduction of fluid or when the drainage system becomes blocked, causing fluid pressure to increase. The high pressure causes damage to the optic nerve, resulting in permanent vision loss. The exact reason the fluid system in the eye stops functioning properly is not completely understood. However, research is constantly being done to further our understanding of Glaucoma.
Open angle glaucoma – the most common form of the disease, has no initial symptoms. It isn’t even evident until the optic nerve becomes damaged and peripheral (side) vision is lost through the slow build up of pressure in the eyes.
Acute closed-angle glaucoma happens more suddenly when blockage occurs in the normal flow of eye fluid between the iris and the lens. This type of glaucoma is a medical emergency and if not treated immediately, blindness could occur in one to two days. Acute closed-angle glaucoma symptoms include:
- Severe pain
- Blurred vision
- Seeing halos around lights
