Selective laser trabeculoplasty, also known as SLT laser treatment, is performed in cases of open-angle glaucoma in order to improve drainage and reduce intraocular pressure (IOP).

On the day of the procedure, patients will be given anaesthetic eye drops to numb the eye and an eyelid holder will be placed between the eyelids in order to prevent blinking. A lens will be placed against the eye as the laser is used is used on the trabecular meshwork inside the eye (the area where fluid drains from the eye). Patients may see flashes of light but otherwise, selective laser trabeculoplasty is completely painless. After treatment, medicated eye drops will be used to control intraocular pressure.

Patients may need to wait for 45 to 60 minutes after treatment so that their ophthalmologist can measure their post-op IOP levels.

Selective laser trabeculoplasty only takes about 10 to 15 minutes to complete and is performed on an outpatient basis. Patients are free to return home immediately after receiving treatment. It is recommended that someone accompany patients on the day of treatment to provide them with a ride home afterwards.

Recovery after Selective Laser Trabeculoplasty | SLT

After treatment, patients will be prescribed with medicated eye drops to alleviate any irritation or swelling in the eye. Patients need to use these eye drops as directed by their retinal specialist and should avoid rubbing their eyes.

Patients can return to their normal daily routines after 2 to 3 days of rest. During this time, there be cloudiness in vision and redness but this will pass.

Any patients experiencing persistent pain or a severe decrease in vision should call Calgary Retina Consultants immediately or go to the emergency room at their nearest hospital.

A follow up examination will be scheduled within 1 to 4 weeks of undergoing selective laser trabeculoplasty to monitor the reduction in intraocular pressure and determine if any additional treatment is needed.
