Glaucoma is a progressive eye disease that can lead to blindness if not treated properly. It is caused by increased intraocular pressure (IOP) that damages the optic nerve. One of the most effective ways to manage this condition is through glaucoma laser surgery, a minimally invasive procedure designed to reduce IOP. If you are wondering what is glaucoma laser surgery, this article will provide a thorough explanation, explore the different types of procedures, and discuss the benefits.
What is Glaucoma Laser Surgery?
What is glaucoma laser surgery? Simply put, it is a medical procedure that uses laser technology to enhance the drainage of aqueous humor (the fluid in the eye) or to reduce the production of this fluid, helping to lower the eye's internal pressure. By reducing the IOP, the surgery helps to slow down or prevent damage to the optic nerve, which is crucial for maintaining vision in glaucoma patients.
There are two primary types of glaucoma laser surgery commonly performed:
Selective Laser Trabeculoplasty (SLT): This is typically used to treat open-angle glaucoma, which is the most common form of the disease. In SLT, a laser targets specific cells in the trabecular meshwork (the eye's drainage system), improving the outflow of fluid and lowering IOP. SLT is favored because it can be repeated if necessary without causing damage to the surrounding tissue.
Laser Peripheral Iridotomy (LPI): This procedure is primarily used to treat angle-closure glaucoma, which occurs when the iris blocks the drainage angle of the eye. During LPI, a small hole is created in the iris with a laser, allowing fluid to flow more freely and relieving pressure.
Both types of glaucoma laser surgery are outpatient procedures that take 10 to 20 minutes to perform, and they are minimally invasive. The eye is numbed with drops before the procedure, making it relatively painless. Most patients can return to normal activities within a day or two.
The Benefits of Glaucoma Laser Surgery
Now that you understand what is glaucoma laser surgery, let's explore why it is such a beneficial treatment option:
Non-invasive and Quick Recovery: One of the main advantages of glaucoma laser surgery is that it is less invasive than traditional surgery. This means there is a shorter recovery time, and patients can resume their regular activities within 24 to 48 hours.
Effective in Reducing IOP: Clinical studies show that laser surgeries like SLT and LPI can effectively lower IOP by 20-30%, which significantly reduces the risk of further optic nerve damage and vision loss.
Repeatable: Another benefit of SLT is that it can be repeated if the initial results wear off over time. Since it causes minimal damage to surrounding tissues, patients can undergo the procedure again if needed, making it a sustainable option for long-term glaucoma management.
Reduced Dependence on Medications: Many patients find that after undergoing glaucoma laser surgery, they can reduce or even stop using daily glaucoma eye drops. This is a significant benefit for people who struggle with the side effects of medication or find it challenging to stick to a strict dosing schedule.
Who is a Candidate for Glaucoma Laser Surgery?
What is glaucoma laser surgery best suited for? Not every glaucoma patient will be a candidate for laser surgery. Typically, your doctor may recommend laser treatment if:
You have open-angle glaucoma that has not responded well to medication
You have angle-closure glaucoma where the drainage canals are blocked by the iris
You are experiencing side effects from glaucoma medications or are unable to follow a daily regimen of eye drops
Your ophthalmologist will assess your specific situation to determine if glaucoma laser surgery is the right treatment for you.
What to Expect Before, During, and After Surgery
Before undergoing glaucoma laser surgery, your ophthalmologist will give you medicated eye drops to reduce eye pressure and numb the eye. On the day of the surgery, you should expect to spend several hours at the clinic due to pre- and post-operative evaluations.
During the procedure, you will be seated in a chair, and a special contact lens will be placed on your eye to guide the laser. Depending on the type of laser surgery being performed, the doctor will use the laser to either improve fluid drainage (SLT) or create a small hole in the iris (LPI). The procedure usually takes less than 20 minutes.
After the surgery, your doctor will check your eye pressure before you leave. You may experience mild discomfort, such as blurry vision or slight soreness, but these symptoms generally resolve within a day or two. Anti-inflammatory drops may be prescribed to prevent inflammation. A follow-up appointment is typically scheduled a week after surgery to monitor your eye pressure.
Risks and Side Effects
While glaucoma laser surgery is generally considered safe, there are potential risks and side effects. These may include:
Mild discomfort or soreness
Temporary blurred vision
In rare cases, elevated eye pressure following the procedure
Post-operative inflammation
Most of these side effects are temporary and manageable with medications. Serious complications are rare but can include long-term damage to the drainage system or a permanent increase in intraocular pressure.
Long-Term Effectiveness of Glaucoma Laser Surgery
The effects of glaucoma laser surgery can last between one and five years. While the surgery is highly effective in reducing IOP, it is not a permanent cure for glaucoma. Many patients will need repeat treatments or additional therapies over time to maintain optimal eye pressure control. However, the procedure provides significant relief and reduces the need for medication in most cases.

FAQs About Glaucoma Laser Surgery
Q1: Is glaucoma laser surgery painful?
No, the procedure is generally not painful. Numbing eye drops are applied before the surgery, and most patients report only mild discomfort.
Q2: How long does glaucoma laser surgery take?
The procedure itself typically takes between 10 and 20 minutes, though you should plan to spend a few hours at the clinic for pre- and post-operative checks.
Q3: Will I still need to use eye drops after the surgery?
Many patients find that they can reduce or stop using eye drops after glaucoma laser surgery, though some may still need them depending on their individual case.
Q4: How soon can I return to normal activities after glaucoma laser surgery?
Most patients can resume normal activities the day after surgery, though it’s advised to avoid heavy lifting or strenuous activity for a few days.
In conclusion, glaucoma laser surgery is a safe and effective method for managing intraocular pressure and preventing optic nerve damage in glaucoma patients. Whether you are dealing with open-angle or angle-closure glaucoma, understanding what is glaucoma laser surgery can help you make informed decisions about your treatment options.
