Common Questions about Istent®

What is glaucoma?

In a healthy eye, ocular fluid is produced, drained, and absorbed in the bloodstream at a constant rate. The ocular fluid is what maintains a healthy eye’s shape. With glaucoma, this process is disrupted and pressure builds in the eye, causing irreversible vision loss due to nerve damage. It is the second-leading cause of blindness, affecting about 200,000 people annually. There are two main kinds of glaucoma—open-angle glaucoma and angle-closure glaucoma.

What causes glaucoma?

Dr. Kruger recommends that all patients receive a comprehensive annual eye exam, because often glaucoma does not manifest in clear symptoms. Risk factors include older age, African American, Hispanic, or Asian ethnicity, genetic history, eye trauma, inflammatory eye conditions, or elevated eye pressure.

What is iStent®?

iStent® is a tiny implant which helps to control the increased pressure in the eyeball due to glaucoma. By creating a permanent bypass from the front of the eye to the eye’s drainage pathway, iStent® is able to increase the flow of fluid and keep pressure at a healthy level.

What should I expect for my iStent® procedure?

iStent® procedures are typically performed during cataract removals, under a local anesthesia. Once the device is implanted, you will not see or feel it in your eye. Patients are able to go home the same day with anti-inflammatory and antibiotic eye drops.

How long is the recovery from an iStent® procedure?

Patients return home the same day as the iStent® procedure with antibiotic and anti-inflammatory eye drops. While recovery is usually fairly quick, it is a good idea to take a couple days off work post-operation. Patients should avoid strenuous activities post-operation to avoid increasing eye pressure.
