iStent inject trabecular micro-bypass stent for the treatment of mild-to-moderate open-angle glaucoma
The most common form of glaucoma is primary open-angle glaucoma. In open-angle glaucoma, the aqueous fluid that normally circulates in the front portion of the eye is blocked from flowing back out of the eye through a tiny drainage system. As a result, the pressure in the eye begins to increase. Consequently, this can damage the optic nerve and lead to vision loss.
The iStent inject trabecular micro-bypass stent, one of the smallest known implants (0.36 mm long x 0.23 mm wide) used in humans. It helps increase the outflow of fluid by creating an opening in the resistant drainage eye layer so that the fluid can flow through, thereby decreasing eye pressure.
Medical-Grade, FDA-Approved Technology
The iStent inject is the FDA-approved, second-generation device of iStent.
Proven Treatment Results
Notably, clinical trials* have shown that most patients with mild-to-moderate open-angle glaucoma implanted with iStent inject have decreased eye pressure and medication. use compared with their previous treatment regimen for at least one year. Moreover, some patient were able to maintain their eye condition without medications.
Traditional glaucoma medication involves the instillation of various eye drops. As consequence, some patients may feel that having to eye drops often is cumbersome and time consuming. Comparatively, iStent Inject is a long-term solution implanted into the eye.
One iStent inject applicator implants two stents into one eye. It can be implanted during a cataract surgery or as a standalone procedure. In a standalone procedure, the doctor will create the same single micro-incision as done in the common cataract procedure.
The doctor will tilt your head slightly. He will place a gonioscope onto your eye which is like a magnifying glass so that he can see the layers of the eye through the microscope. The iStent inject applicator which contains the stents will be inserted into the eye through the tiny incision, and the doctor will gently implant one stent into the resistant layer, move two-clock hours over and implant the other stent into the same layer. The applicator is then withdrawn.
Above all, iStent is a good treatment option for patients with mild-to-moderate open-angle glaucoma who need to lower eye pressure. Additionally, it is a convenient choice for those who wish to reduce medication burden, find it difficult to comply with medical therapy or have side effects from traditional glaucoma medication.
Clinical trials have shown iStent inject procedure and implant to be a safe and effective treatment option alternative for patients with mild-to-moderate open angle glaucoma. The few minor adverse events reported were treatable or resolved on their own.
