The iStent is a tiny, FDA-approved medical device that can be implanted on its own or during cataract surgery to improve the drainage of fluid from the eye, thereby reducing eye pressure and managing the progression of glaucoma. It is the smallest implantable device available for surgical use.

The iStent bypasses any blockages or resistance in the natural drainage system of the eye, facilitating a more efficient and consistent flow of fluid. This helps to lower the eye pressure, which is crucial in managing glaucoma and preventing further damage to the optic nerve.

One of the key advantages of the iStent is its minimally invasive nature. It is typically inserted through a small incision. The iStent is made of biocompatible materials that are well-tolerated by the body, reducing the risk of complications or adverse reactions.

Studies have shown that the iStent can significantly reduce IOP and decrease the need for glaucoma medications in many patients.
