Glaucoma Laser Surgery
Selective Laser Trabeculoplasty (SLT):
This laser procedure aims to improve the outflow of aqueous humor by treating the trabecular meshwork. SLT is used to treat open-angle glaucoma. It is performed in the office and is safe, painless, and non-invasive. Several clinical trials have demonstrated the safety and efficacy of SLT as a first-line glaucoma treatment.
How does SLT work?
The laser energy stimulates the cells in the drain of the eye, the trabecular meshwork, to function more effectively, which results in greater fluid outflow from the eye. This in turn lowers the pressure inside the eye.
What can I expect during an SLT treatment?
SLT is an outpatient procedure performed in our office. Anesthetic eye drops are used to numb the eye. You will sit at a laser, similar to a slit lamp, and a laser lens is placed on the eye to help focus the laser beam. The application of the laser takes only a few minutes. There is usually no pain during or after the treatment.
What can I expect after SLT treatment?
You may resume normal activities immediately. The eye may be mildly blurry or irritated for a few hours to a day after the procedure. You will use a short course of anti-inflammatory eye drops. A follow-up appointment is usually recommended in about 4 weeks to assess the effect of the laser.
How many treatments are required?
As with any medical procedure, results may vary. Unlike daily eye drops, SLT therapy is administered in a single session in a simple, fast, in-office procedure. Because glaucoma is a chronic disease, follow-up appointments are important. SLT can be safely repeated in the future if necessary
Is SLT covered by Medicare?
Yes, SLT is covered by Medicare and most insurance providers, potentially saving you thousands of dollars in prescription medication costs.
What are the side effects with SLT?
Unlike many glaucoma medications, there are no incidences of allergy or systemic side-effects with SLT. Complications are rare, but may include inflammation, a temporary increase in eye pressure, blurred vision, headache, red eye, corneal abrasion, or eye pain.
Will I need to continue using eye drops after SLT treatment?
Sometimes SLT can eliminate the need for one eye drop. It will depend on a case by case basis.
Laser Peripheral Iridotomy (LPI):
LPI is a laser procedure used for treating specific types of glaucoma, such as narrow angle and angle closure glaucoma. It involves creating a small hole in the peripheral iris to improve the flow of aqueous humor.
