Selective laser trabeculoplasty (SLT) is a type of laser surgery that is used to treat patients with glaucoma by lowering intraocular pressure. SLT can reduce eye pressure by 20-30%, but its efficacy varies from patient to patient and depends on the patient’s eye tissue and how long they have been on medication to control intraocular pressure.

Goals of

Pros and cons of

Selective Laser Trabeculoplasty

Pros

-SLT is suitable for patients with glaucoma that is not adequately managed by eye drops or who experience adverse effects from the eye drops.

-The effects of SLT last approximately 1-5 years and the procedure can be repeated several times without impact to the healthy tissues of the eye.

-SLT is not associated with systemic side effects.

-SLT stimulates the body’s natural healing mechanisms to enhance outflow of the fluid in your eye, thereby reducing intraocular pressure without causing any damage to the sensitive structures in the eye.

Cons

-Possible risks associated

How it works:

Selective Laser Trabeculoplasty

SLT is an outpatient procedure and does not take long Anesthetic eye drops will be administered before the procedure. It takes 15-30 minutes for them to take effect. Drops will be given to dilate the pupils. Some patients may experience a headache due to this. The procedure takes approximately 10 minutes per side. During the procedure, lens will be placed on your eyes to keep you from blinking.

Preparation before

Selective Laser Trabeculoplasty

Pre - treatment

Selective Laser Trabeculoplasty

Post - treatment

The procedure is done using anesthetic eye drops and is done at the Eye Center. Your vision will be normal after the procedure. Avoid using your eyes too much for a day or two after the procedure and wear sunglasses for a couple of days after the procedure. Do not rub your eyes for a few days after the procedure. You can wash your face and hair and wear make-up normally after the procedure. The doctor will prescribe eye drops to reduce inflammation that you will use for 7-10 days.

Risks & side effects

-Eye irritation, eye pain, light sensitivity, increased eye dryness.

-Failure of the procedure to lower intraocular pressure.

-Reports have shown that approximately 5% of patients will experience an increase of intraocular pressure (Leahy KE & White AJ, 2015), which can be prevented with eye drops after the procedure.

FAQs:

Selective Laser Trabeculoplasty

How do I know SLT has worked?

There is no sensation/feeling associated with SLT treatment. You will require follow-up visits with your doctor to monitor the success of the treatment.

‍

What is the success rate of SLT?

About 70-80% of patients will experience decrease of intraocular pressure without requiring eye drops (Leahy KE & White AJ, 2015). Success depends on how long eye drops have been used to manage intraocular pressure.

‍

What would happen if this procedure is not performed?

Intraocular pressure will not decrease and can cause further damage to the nerves of the eyes, requiring further use of eye drops or perhaps even surgery. Please talk to your doctor about your condition and all options available for you.

‍

How long is the recovery?

Your doctor may treat your eye with anti-inflammatory eye drops following treatment, but this will not affect your vision. Immediately following treatment you will be able to complete everyday activities, including driving your car.

‍

How often do I need to undergo SLT?

One application of SLT treatment typically results in pressure reduction for several years. Depending on your individual circumstances, however, another application may be needed at some point in the future.
