SLT is an outpatient procedure performed in our ambulatory surgery center. Eye drops are used to numb the eye and treatment takes place in a standard exam chair with a slit lamp like the one used to examine your eye. The SLT laser is attached to the slit lamp. A contact lens is then used to hold your eye open and focus the laser energy onto the drainage area of your eye. Laser energy is released multiple times at the edge of your pupil and the procedure will take just a few minutes to complete. Most patients do not report pain during or after the treatment.
