What Is The iStent?

Minimally invasive glaucoma surgery (MIGS) techniques have come a long way in recent years, allowing our board-certified ophthalmologists the ability to reduce intraocular eye pressure (IOP) effectively. One of these approaches is the iStent Micro-Bypass device, the world’s smallest implantable medical piece that works by providing a pathway for drainage through the trabecular meshwork of the eye. This MIGS procedure is intended for individuals who have both cataracts and glaucoma. Patients with open-angle glaucoma usually get the best results. Get in touch with Focal Point Vision in San Antonio, TX to schedule a consultation.

What Are The Benefits Of The iStent?

The iStent offers a number of great benefits to treat glaucoma and improve overall eye health, including:

How Is The iSTENT Done?

Typically performed alongside cataract surgery, the implantation of the iStent is done as an outpatient procedure at Focal Point Vision. Before we begin the treatment, your eyes will be numbed with eye drops, and you may be given a mild sedative to ensure your comfort. For individuals who are having cataract surgery in conjunction with their iStent implant, our ophthalmologists use the same opening to perform both procedures. Its placement within the trabecular meshwork helps with the aqueous flow in the eye and lowers IOP, which can reduce a patient’s reliance on glaucoma eye drops and other medications.

iStent FAQ

Is the iStent FDA-approved?

Yes, it is. The FDA approved the iStent in 2012 to relieve intraocular pressure in glaucoma patients.

Does having an iStent placed hurt?

No, it doesn’t. Our board-certified ophthalmologists will numb your eyes with anesthetic drops and may also give you a mild sedative to keep you comfortable during the procedure.

How successful is iStent surgery?

Clinical studies have shown that as many as 68% of patients with glaucoma who were treated with the iStent didn’t need medication at the one-year mark after treatment.

What is the iStent made out of?

The iStent is made from medical-grade titanium with a heparin coating.

How long is recovery after iStent surgery?

Recovery after having an iStent placed is relatively quick. The iStent is placed in an outpatient procedure, meaning you can go home after your surgery (but you shouldn’t drive yourself). The treated eye may be covered with a shield which can be removed the next day. You will be prescribed antibiotic and anti-inflammatory drops which you are typically used for 4 – 6 weeks. Though recovery time is quick, we may recommend taking up to a week off from work as you recover. You should also avoid strenuous activities during this time.
