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.

Testimonials

  • 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!

  • 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.

  • My entire family have been seeing Dr. Krywko for years. The professionalism, care and focus are over the top. I was told by an optician I would not be a likely candidate for contact lenses. However with Dr. Krywko's patience and wisdom she was able to fit me for contact lenses that work perfectly! I am thrilled..........Plus, I also have the most gorgeous frames (when I do not want to wear my contacts. ) I receive comments every time I wear them, " where did you get your glasses!" Dr. Kryko just received the newest styles......I'm in trouble..........
