Why do you need laser surgery for glaucoma?
Laser surgery is a treatment to help control glaucoma (glaw-KO-muh). You may need it if your glaucoma medicines are not helping to keep your eye pressure low enough. You may also have it as a first treatment of glaucoma. Glaucoma is an eye disease. A clear fluid flows through passages inside your eye all the time.
What happens when you have glaucoma?
With glaucoma, these passages get clogged or blocked. When this happens, fluid in your eye builds up and causes too much pressure inside the eye. Too much pressure against the optic nerve can lead to damage and loss of your vision (sight). Laser surgery uses a tiny, powerful light beam to help your eye drain fluid more easily.

What is the procedure for glaucoma?
A laser iridotomy can be performed for those with angle-closure glaucoma. In this form of glaucoma, the drainage angle between the iris and the cornea (the clear front window of the eye), called the trabecular meshwork, is too small. This narrow/closed angle restricts proper drainage of fluid from the eye, leading to increased intraocular pressure (IOP) and vision loss associated with glaucoma. During a laser iridotomy procedure, a laser is used to create a small opening in your iris to widen the drainage angle and to allow fluid to flow more freely through the trabecular meshwork. This may lead to a reduction in IOP.
What is the drainage angle between the iris and the cornea called?
In this form of glaucoma, the drainage angle between the iris and the cornea (the clear front window of the eye), called the trabecular meshwork, is too small. This narrow/closed angle restricts proper drainage of fluid from the eye, leading to increased intraocular pressure (IOP) and vision loss associated with glaucoma.
How to do LPI?
Here’s what you can expect from your LPI surgery: 1 First, the eye is anesthetized. This is done using the same types of eye drops used for measuring eye pressure. Some additional preparatory eye drops may also be used. 2 Next, the patient is set up in front of the laser, which looks like the typical examination microscope. 3 Then a contact lens is temporarily placed on the eye. 4 The laser beam is aimed and multiple laser “shots” are placed into the iris. (Laser surgery is not painful although the patient may feel a “pop” in the eye or an occasional pin-prick type sensation.) 5 At the end of the laser peripheral iridotomy surgery, the contact lens is removed and the eye rinsed out. Another eye drop may then be given. 6 Your eye pressure will be checked 30-60 minutes after the procedure is completed. 7 After your iridotomy, you may notice some blurry vision, mild discomfort, or a foreign body sensation in your eye. These symptoms are usually transient and are gone within a few hours to a few days. You may also be given some anti-inflammatory medication to use for a few days to a week to prevent any significant inflammation.
