Minimally Invasive Glaucoma Surgery in India

MIGS covers a group of tiny devices and procedures, such as trabecular micro-stents and canal-opening techniques. Most work from inside the eye through the same small corneal cut used for cataract surgery. They improve the eye's own drainage route rather than building a new one on the outside of the eye.

Because the white of the eye is left largely untouched, recovery is quick and serious complications are less common. The trade-off is a smaller drop in pressure. For this reason, MIGS is mainly offered in early to moderate glaucoma, and some patients still need drops afterwards.

How this approach differs

Standard glaucoma surgery builds a new drain under a flap in the white of the eye, giving strong pressure lowering but needing intensive follow-up. MIGS works through a tiny corneal cut with micro-devices placed in the natural drainage angle, so the eye surface is spared and healing is faster. Pressure falls less, so MIGS suits mild to moderate glaucoma, often at the time of cataract surgery. Devices vary in availability, so confirm which one your hospital uses.

• Glaucoma SurgeryStandard approach

Who needs minimally invasive glaucoma surgery

• Mild to moderate open-angle glaucoma
• Patients having cataract surgery
• People who struggle with drops
• Those wanting lower risk surgery

How it is done

1. Local anaesthesia is given.
2. A tiny corneal cut is made.
3. A special lens views the drainage angle.
4. A micro-stent or device is inserted into the drainage system.
5. The cut seals itself.
6. Drops are started after surgery.

Before you travel to India
