MINIMALLY INVASIVE GLAUCOMA SURGERY (MIGS) – ISTENT INJECT

Minimally Invasive Glaucoma Surgery using the iStent inject is an advanced surgical service designed to help lower eye pressure in patients with glaucoma. The procedure improves the natural outflow of fluid inside the eye by implanting tiny drainage devices into the eye’s natural drainage pathway. As a result, eye pressure decreases and the risk of glaucoma progression may be reduced.

WHAT THIS SERVICE TREATS

This procedure treats open-angle glaucoma, a chronic condition that damages the optic nerve due to elevated eye pressure. Glaucoma often progresses silently and can lead to permanent vision loss if not controlled. Therefore, ophthalmologists recommend MIGS as part of a pressure-lowering strategy when medications alone do not achieve target pressure or cause side effects.

HOW THE PROCEDURE WORKS

During surgery, the surgeon places one or more microscopic iStent inject devices into the eye’s natural drainage channel. These implants create a direct pathway for fluid to exit the eye more efficiently. The surgeon commonly performs this procedure through a small incision and often combines it with cataract surgery when appropriate. Consequently, surgical trauma remains minimal and recovery is usually faster than with traditional glaucoma surgery.

WHO MAY BENEFIT

MIGS with iStent inject may benefit patients with mild to moderate open-angle glaucoma. For example, it may help the following individuals.

1. Glaucoma and coexisting cataracts
2. Requiring better pressure control despite medications
3. Experiencing medication intolerance or poor compliance
4. Seeking a less invasive surgical option
5. Suitable for angle-based glaucoma surgery

RECOVERY AND AFTERCARE

Most patients resume normal activities within days. Vision may fluctuate briefly as the eye heals. However, discomfort is usually mild. Therefore, patients follow prescribed eye drop regimens and attend scheduled follow-up visits to monitor eye pressure and implant position. The surgeon adjusts medications based on response and healing.

SAFETY AND CLINICAL CONSIDERATIONS

MIGS procedures have a strong safety profile when surgeons select patients carefully. Still, risks include inflammation, temporary pressure changes, bleeding, or the need for additional treatment. Thus, comprehensive evaluation and long-term monitoring remain essential for glaucoma care.
