Here at Cascadia Eye, you know our doctors are always looking for the newest and best technologies available for every aspect of your vision. From custom, bladeless iLASIK to advanced testing equipment and more, this forms one of the three cornerstones of our commitment (providing comprehensive service, care that is personal and local, and investing in proven technologies).
Which is why we’re excited to tell you about the iStent (full name: iStent Trabecular Micro-Bypass), a new piece of technology that our surgeons can add to cataract surgery for patients who also have glaucoma. Our surgeons have been using this tiny device for about a year now, and its results are amazing.
How the iStent Works
If you’ve heard of the stent used in surgeries to prevent heart attacks and strokes, the iStent works much the same for eye pressure. A stent helps with vessel flow when blood vessels get clogged, and the iStent does the same for the eye’s drainage system when a patient has glaucoma. As we explain on our glaucoma page, if the eye is unable to drain properly, pressure within the eye mounts.
The iStent is placed in the area of blockage, creating a permanent opening that keeps the outflow going, and therefore lowering the eye pressure. If you and your eye surgeon agree that the iStent is right for you, it can be easily placed during cataract surgery, where it will begin working right away.
Depending on the severity of glaucoma and other individual factors, the iStent may not fix the pressure problem entirely or remove the need for glaucoma medications. But it does safely relieve pressure in a permanent way, regardless of the extent.
Also interesting to note: according to Glaukos, the makers of the iStent, it is also “the smallest medical device ever approved by the FDA” – 20,000 times smaller than the (already tiny) intra-ocular lens used in cataract surgery. You can read more details about this amazing micro-device on the Glaukos website.
