There are two types of laser trabeculoplasty:
- Argon laser trabeculoplasty (ALT)
- Selective laser trabeculoplasty (SLT)
Argon laser trabeculoplasty (ALT)
Laser trabeculoplasty uses a very focused beam of light to treat the drainage angle of the eye. This surgery makes it easier for fluid to flow out of the front part of the eye, decreasing pressure in the eye. Laser trabeculoplasty can be done without the patient being admitted to the hospital.
SLT uses a lower-power laser than ALT does.
For laser trabeculoplasty
- The doctor will put drops in your eye to numb the eye.
- A special microscope (slit lamp) and lens (goniolens) are used to guide the laser beam to the canals (trabecular meshwork) where fluid drains from the eye.
- The doctor makes small burns in the trabecular meshwork.
- At the end of the surgery, the doctor will put drops in your eye to prevent eye pressure from rising right away.
