Trabeculectomy is often used to treat open-angle glaucoma. It’s done in a hospital and usually takes less than an hour. It involves creating a tiny opening in the top of your eye. The opening will be under your eyelid, where no one will see it. This opening allows extra fluid in your eye to drain away, lowering pressure in your eye.
Glaucoma implant surgery is used to treat several types of glaucoma, including congenital glaucoma, neovascular glaucoma, and glaucoma caused by an injury. It’s done in a hospital and normally takes 1 to 2 hours. In this operation, the surgeon implants a tiny tube, or shunt, onto the white part of your eye. The tube helps extra fluid drain out of your eye, lowering your eye pressure.
Usually, you’ll be awake during these surgeries — but you’ll get numbing medicine and medicine to help you relax. You can usually go home the same day, but you’ll need someone to drive you home.
If you have mild glaucoma, your doctor may recommend a new approach called minimally invasive glaucoma surgery (MIGS). This also lowers eye pressure, but it has fewer risks and side effects and helps you recover faster. There are different types of MIGS, so ask your eye doctor about whether MIGS may be an option for you.
