iStent

patient under surgery

The iStent Trabecular Micro-Bypass is a surgical device that is available for use in treating patients with mild-to-moderate open-angle glaucoma.

Glaucoma is characterized by an excessive accumulation of fluid inside the eye, which leads to an increase in the inner eye pressure (intraocular pressure). This can damage the optic nerve and lead to a gradual loss of vision.

How iStent Works

One cause of glaucoma is poor drainage of the fluid inside the eye, which, again, leads to increased intraocular pressure. The iStent device works by providing a permanent path for fluid to flow out of the eye. By restoring the flow of fluid, the pressure inside the eye is reduced.

While the device is used to treat glaucoma, it is implanted during cataract surgery. This is done as an outpatient surgery, which means you can go home after the procedure is finished.

The device is made of titanium and is very small (only 1 millimeter long). Once it is in place, you will not be able to see or feel it.

Safety and Benefits of iStent

After iStent surgery, most patients’ vision improves that day. Many are also able to stop using medicated eye drops to reduce the pressure inside their eye. Others may be able to reduce the number of eye drops they need to use to control their inner eye pressure.

The iStent device is implanted during a surgical procedure. The most common side effects after surgery are:

  • Swelling of the cornea (corneal edema)
  • Decrease in how well you can see with glasses or contacts (best corrected visual acuity)
  • Thickening of the back of the eye’s lens capsule, which causes cloudy vision
  • Blockage of the iStent device
  • Blurred vision
  • Increased pressure inside the eye

The iStent device is not recommended for people with certain conditions such as angle-closure glaucoma, certain eye tumors and thyroid eye disease.

Reviews From Our Satisfied Patients

    Dr. Candria Kryko is a wonderful OD. I was seen by Dr. Kryko in Scottsdale recently for an eye exam/contact lens fitting. She is extremely pleasant, attentive, and she took her time to give me a thorough exam and answer all of my questions. Dr. Kryko gave me recommendations on contacts and eye drops, as well, she gave me tips on how I can save on some of my contact expenses. She was professional, attentive, took the time to explain what was needed, and was simply nice to be around. I recommend Dr. Kryko.

    By far the best experience I've had. She took her time to know me, and I received education about my eyesight, and choices I had. The modern technology showed me my options with a prescription and without. The office was on time, professional and inviting. The best for the entire family.

    Dr. Krywko listens and identifies the issues with the eyes! I don’t feel like a number - the time was spent to understand what issues I was having and a comprehensive solution developed! I followed Dr. Krywko from her previous location as she’s THAT good! The team she has surrounded herself with is top notch as well! (Thank you Liz)

    I have worn contact lenses for years but due to my strong near-sighted prescription with high astigmatism could get neither the comfort nor vision very good in standard gas permeable lenses or in soft lenses. I had reverted back to wearing glasses most of the time until Dr. Krywko recommended the SynergEyes lenses. They work great for me and I can finally wear contacts again! Thank you, Dr. Krywko!

    Being new to this state, I can honestly say this is the best eye doctor and I made a good decision coming here. They took the time and patience to help!
