How Do Eye Doctors Treat Glaucoma?

At Georgia Center for Sight, Dr. Dong offers a variety of glaucoma treatments, all of which aim to lower eye pressure and avoid further vision loss.

Medicated Eye Drops

Glaucoma eye drops are typically the first treatment method eye doctors use to help control glaucoma. There are many different kinds of prescription eye drops available for the treatment of glaucoma, so your eye doctor may have you try a few before finding the one that works best for you.

In some cases, you may need to use these prescription eye drops in combination with another glaucoma procedure to ensure your eye pressure is within a healthy range.

Glaucoma Laser Procedures

At Georgia Center for Sight, Dr. Gong performs glaucoma laser procedures to help treat glaucoma. 

Selective Laser Trabeculoplasty

SLT, or selective laser trabeculoplasty, is an in-office laser procedure used in patients with open-angle glaucoma. In this short procedure, your eye doctor will use the laser to create an opening in the drainage structure of the eye, called the trabecular meshwork, to improve the outflow of fluid.

When fluid is able to pass through the drainage channels more efficiently, it can lower eye pressure. 

Laser Peripheral Iridotomy

Another laser procedure performed at Georgia Center for Sight is called a YAG PI or a laser peripheral iridotomy. The LPI procedure is performed with a YAG laser for those with narrow-angle glaucoma or those at risk for angle-closure glaucoma. 

The LPI procedure is also a quick, in-office procedure where your eye doctor uses the YAG laser to create a small hole in the iris. This small hole helps fluid flow freely out of the eye and reduces pressure inside the eye.


Durysta is a tiny, tube-like device that your eye doctor can implant into your eye during a short medical procedure. Durysta works by slowly and automatically releasing medication, which helps to lower IOP. This implant is intended to be a long-term treatment option for patients with glaucoma.


Trabeculectomy is a type of glaucoma surgery that aims to reduce eye pressure by creating a new outflow pathway for the fluid in the eye. During the procedure, your eye surgeon will remove a small piece of tissue from the drainage channel of the eye. 

This will create a wider pathway for fluid to leave the eye.


MIGS stands for Minimally Invasive Glaucoma Surgery. With this type of glaucoma surgery, intraocular pressure is reduced with minimal disruption to the eye’s anatomy. A MIGS procedure can be performed in combination with cataract surgery on patients with mild to moderate glaucoma. At Georgia Center for Sight, Dr. Dong offers the following MIGS procedures:

Kahook Dual Blade

The Kahook Dual Blade is a surgical instrument used during MIGS to remove tissue from the eye’s drainage system. It features two blades, one of which is used to hold the tissue while the other cuts it. 

This design allows for greater precision and control during the procedure. Once this tissue is removed, fluid will be able to flow efficiently out of the eye, which reduces eye pressure and prevents further vision damage.


The iStent is a small medical device that is used to treat glaucoma. The device is inserted into the eye during MIGS.

It creates a small opening in the drainage channel of the eye, so that more fluid can drain out and intraocular pressure can be reduced. The iStent aims to lower intraocular pressure in adult patients with mild-to-moderate open-angle glaucoma.
