The iStent® implant is the smallest, FDA approved medical
device often recommended for patients with mild to moderate Open-Angle Glaucoma
who are going to have cataract surgery.
Your eyes use an intricate fluid outflow system to keep them
balanced and healthy. At the center of
this system is a drainage network called the “Trabecular Meshwork,” which is
the anatomy through which fluid exits the eye.
Most of the fluid in your eye naturally drains through this meshwork and
into the bloodstream through a structure called Schlemm’s Canal.
In patients with Open-Angle Glaucoma, a blockage in the
trabecular meshwork is the primary cause of keeping the fluid in your eye from
draining properly. When this happens,
fluid backs up and pressure in your eye rises.
High Intraocular Pressure of IOP, can lead to blindness, which is why
controlling this pressure in the eye is extremely important.
Most people with Open-Angle Glaucoma take one to three
powerful medications to reduce their IOP.
While these drugs are effective, they are expensive and often have
undesirable side effects. As a result,
some patients choose not to use their medications as prescribed, which can lead
to permanent vision loss.
The iStent® is implanted during your cataract surgery,
without the need for additional incisions or anesthesia. After the cataract is removed and the
Intraocular Lens of your choice is positioned, the iStent is inserted through
the trabecular meshwork and into Schlemm’s Canal. This creates a permanent opening that
increases the outflow of fluid and safely lowers intraocular pressure. After the procedure, Dr. Bogart may recommend
a reduction in the number or the amount of glaucoma medications you are
currently using.
