iStent in Dallas / Fort Worth

Treating Glaucoma & Cataracts Simultaneously

As many as three million Americans suffer from glaucoma. This is a serious eye condition that can cause permanent and irreversible vision loss. Anyone, of any age, can have it, but it is estimated that at least 50% of glaucoma sufferers are unaware of their condition.

Extenuating risk factors for glaucoma include:

  • Diabetes
  • Eye injuries
  • Steroid / cortisone use
  • High eye pressure
  • African heritage
  • 45 years of age or older, without a history of annual eye exams
  • Nearsightedness
  • Glaucoma in your family medical history

If you suffer from mild to moderate glaucoma, the good news is that there are treatments available. Talk to our Dallas / Fort Worth Metroplex eye doctors at Key-Whitman Eye Center about iStent, an exciting and advanced glaucoma technology that works to unclog the eye’s natural drainage system and thus relieve damaging pressure within the eye. If you are scheduled for a cataract surgery and a sufferer of open-angle glaucoma, you may be able to manage your glaucoma while treating cataracts simultaneously using an exciting treatment called the iStent Trabecular Micro-Bypass Stent.

What is iStent?

iStent is the world’s smallest medical device. It is 20,000 times smaller than the intraocular lens (IOL) your surgeon will be implanting in your eye as part of your cataract procedure. Despite its small size, the results of iStent can be life changing.

Here’s how iStent works.

Glaucoma is a condition that occurs when the eye’s natural draining system is congested and blocked. This leads to high pressure within the eye that can actually cause serious and irreversible vision loss over time. iStent is designed to release that pressure by breaking the blockage. The tiny device is implanted during the cataract surgery and works to permanently open the blockage creating a path for flow, allowing pressure release.

Consult our Dallas / Fort Worth Metroplex Ophthalmologists.


IStent is not available to patients with severe glaucoma. We will discuss the available options and alternatives with you as well as any potential risks or side effects. In some cases, the implantation of the IStent is not successful. After IStent, it is important to follow the instructions of your eye doctor and to maintain follow-up visits to monitor your eye pressure and to watch for potential adverse reactions to the IStent including but not limited to edema and changes in your vision. It may take up to 3 months for healing and it is not uncommon for your pressures and your vision to fluctuate during this time. Some patients are able to reduce their use of glaucoma medicated eye drops however, some are not. We ask that you never stop using your drops unless your eye doctor has instructed you to do so.
