Targeted Laser Trabeculoplasty is a treatment often used to help lower eye pressure in people with glaucoma. This procedure uses a laser to improve fluid drainage in the eye, which can protect the optic nerve. It is done in a simple and safe way, often as an outpatient treatment. This article explains the steps taken before, during, and after the SLT procedure, so patients know what to expect.
Preparing for the Procedure
Before the day of the selective laser trabeculoplasty treatment, patients usually have a consultation with their eye doctor. The doctor will ask about health history and any medications taken. Sometimes, patients must stop some medicines before the procedure. It is important to follow any instructions given by the clinic to make sure the eye is ready for treatment. Patients may be asked to come with someone to drive them home. This preparation helps make the procedure smoother and safer.
Arrival and Pre-Treatment Assessment
On the day of the procedure, patients will check in and confirm their details. The medical team will measure eye pressure and check vision to have a clear baseline. These tests help the doctor plan the treatment accurately. The patient may be asked about any changes in vision or discomfort since the last visit. This assessment sets the stage for the procedure and helps ensure safety.
Anesthesia and Eye Preparation
Before the laser treatment starts, the eye will be cleaned and numbed. Local anesthetic drops are applied to prevent pain during the procedure. The patient might feel a mild sting or cold sensation when the drops are put in. The doctor may place a small lens on the eye to focus the laser beam precisely. Patients must keep their eyes still and look at a target light during the treatment. This stage is quick and painless for most people.
The Laser Treatment Process
During SLT, the doctor uses a laser to gently open clogged drainage canals in the eye. The laser light is applied in short bursts around the edge of the iris. Patients may see bright flashes or spot lights while the laser is active. The procedure usually lasts about five to ten minutes. Patients should try to remain calm and still to help the doctor aim the laser carefully.
Sensations and Expectations During Treatment
Most patients experience little to no pain during this procedure. Some may feel slight discomfort or pressure in the eye. There is no need to worry if the eye feels a bit sensitive afterward. Vision may be blurry for a few hours after the procedure. It is normal to have mild redness or irritation too. These effects usually improve quickly without needing medicine.
Immediate Recovery and Post-Procedure Care
After the laser is done, patients rest briefly while the doctor checks the eye pressure again. Eye drops may be given to reduce inflammation and prevent infection. Patients should avoid rubbing their eyes and follow instructions for using any prescribed drops. It is best to avoid heavy activity and bright lights for a day or two. Regular follow-up visits will monitor how well the eye is healing.
Follow-Up and Monitoring After Treatment
Patients must have follow-up appointments to see how the eye responds to SLT. The doctor will measure eye pressure and check for side effects. The full benefit of the laser may take a few weeks to appear. If eye pressure is still high, additional treatments might be needed. Long-term care is important to keep eye pressure under control and protect sight.
Glaucoma patients should consider selective laser trabeculoplasty to lower eye pressure. It involves careful preparation, use of local anesthesia, and a brief laser treatment. Most patients experience minimal discomfort and recover quickly with simple care. Close monitoring after the procedure helps achieve the best results. Understanding each step can make the experience less stressful and support better eye health.
