Understanding Selective Laser Trabeculoplasty (SLT)
If you have been diagnosed with glaucoma or high eye pressure, Selective Laser Trabeculoplasty (SLT) is a gentle and highly effective option to protect your vision. Unlike traditional surgery, SLT is a quick, in-office procedure that uses a precise laser to stimulate the eye’s natural drainage system. By improving fluid outflow, SLT safely lowers intraocular pressure, which is critical for preventing long-term damage to the optic nerve.

Many patients prefer SLT because it is non-invasive and often reduces or eliminates the need for daily eye drops, which can be difficult to manage. The treatment is virtually painless and requires no downtime, making it an excellent choice for adults who wish to maintain an active lifestyle while ensuring their ocular health. Dr. Mihok and our team will guide you through every step, ensuring you feel comfortable and remain informed throughout the process.
Key Benefits: Non-invasive, quick recovery, and effective pressure management for long-term vision protection.
Benefits and Outcomes of SLT
Selective Laser Trabeculoplasty (SLT) is a gentle treatment designed to lower eye pressure and protect your vision with minimal impact on your daily routine.
- Lowering eye pressure effectively to prevent vision loss.
- Reducing or eliminating the need for daily eye drops in some patients.
- Quick recovery with most patients returning to activities immediately.
- Performed as a comfortable outpatient procedure in our office.
- Please note that results and the duration of the treatment effect can vary by patient.
What to Expect: Your SLT Treatment Journey
1. Preparation & Check-In
When you arrive, we will verify your clinical information and prepare you for the procedure. Dr. Mihok’s team will apply special numbing drops to ensure you remain completely comfortable. You may also receive drops to temporarily constrict your pupil, which helps the laser target the drainage tissue more effectively. There are no needles and no general anesthesia required.
2. The SLT Procedure
The treatment itself is remarkably quick, typically taking only 5 to 10 minutes. You will sit at a machine similar to the one used during a standard eye exam. A special lens is placed on your eye to direct the laser light. During the treatment, you may see flashes of green light and hear a soft clicking sound. Most patients describe the sensation as a minor pressure or a small 'tap' on the eye, but no sharp pain.
3. Recovery & Results
Following the procedure, your eye pressure will be checked before you go home. Your vision may be briefly blurry from the drops, but this clears quickly. There are no restrictions on your activity—you can return to reading, watching TV, or gentle exercise immediately. We will schedule a follow-up visit in a few weeks to measure the full effect of the treatment. Most patients see a significant drop in pressure within 1 to 3 months.
Frequently Asked Questions
Why do I need SLT (Laser Surgery)?
SLT is recommended to lower high eye pressure that can cause damage to your optic nerve. It is often used as a direct alternative to daily eye drops or when drops aren’t providing enough pressure control.
Does the procedure hurt?
The treatment is virtually painless. We use special numbing drops before we begin. Most patients feel very little sensation, perhaps a slight 'tap' or mild pressure on the eye during the laser flashes.
How long does the treatment take?
The actual laser procedure typically takes only 5 to 10 minutes per eye. You should plan to be in our office for about an hour total to allow for preparation and a brief pressure check afterward.
What will my vision be like afterward?
Your vision may be slightly blurry immediately after the treatment due to the drops we use, but this usually clears within an hour or two. Most patients see normally by the time they get home.
Can I drive myself home?
We recommend having a driver for your appointment. While your vision clears quickly, the drops can cause temporary light sensitivity or mild blurring that makes driving uncomfortable right away.
Are there risks or side effects?
SLT has an excellent safety profile. The most common side effects are mild eye irritation or a brief 'scratchy' feeling for a day. Significant complications like infection or inflammation are very rare.
How long do the results last?
The pressure-lowering effect typically lasts for 1 to 5 years. Because SLT is a 'cold' laser and does not cause scarring, it can often be repeated safely if the eye pressure begins to rise again in the future.
When should I call the office?
Please call us if you experience a significant decrease in vision, severe pain, or heavy discharge. While mild redness is normal, any sudden changes should be reported to Dr. Mihok immediately.
