Laser Procedures for Glaucoma
Quick, in-office laser treatments that can effectively lower eye pressure and reduce your dependence on glaucoma medications.
Selective Laser Trabeculoplasty (SLT)
SLT is a modern laser treatment that improves the eye's natural drainage system to lower intraocular pressure without the need for daily eye drops.
How SLT Works
SLT uses gentle laser energy to stimulate the eye's drainage channels and improve fluid outflow. This results in the lowering eye pressure.
- "Selective" targeting preserves healthy tissue
- Treats only specific cells in drainage system
The Procedure
SLT is a quick, comfortable in-office procedure.
- Takes only 5-10 minutes to perform
- Numbing drops prevent discomfort
- Return to normal activities immediately
Benefits of SLT
Reduces Medication Burden
May eliminate or reduce need for daily eye drops
Long-Lasting Results
Effects typically last 3-5 years or longer
Minimal Side Effects
Very safe with few complications
Repeatable Treatment
Can be performed again if pressure rises
What to Expect After SLT
- • Pressure may take 4-6 weeks to reach its lowest point
- • Temporary pressure spike possible in first 24 hours (monitored by your doctor)
- • Mild eye irritation or blurred vision for a day or two
- • Anti-inflammatory drops prescribed for several days
- • Continue current glaucoma medications until instructed otherwise
Laser Peripheral Iridotomy (LPI)
LPI creates a small opening in the iris to prevent or treat angle-closure glaucoma by allowing fluid to flow more freely within the eye.
Purpose of LPI
LPI prevents angle-closure glaucoma by creating an alternative pathway for fluid to move from behind the iris to the front of the eye.
- Prevents dangerous pressure spikes
- Treats narrow drainage angles
- Often performed preventively
The Procedure
LPI is a quick in-office procedure.
- Very brief procedure (5 minutes)
- Numbing and pupil-constricting drops used
- Creates tiny opening invisible to others
Who Needs LPI?
Your ophthalmologist may recommend LPI if you have:
Narrow Drainage Angles
At risk for angle-closure glaucoma
Acute Angle Closure
Emergency treatment after attack
Fellow Eye Protection
Prevent attack in other eye
Plateau Iris Syndrome
Anatomical configuration issue
Recovery After LPI
- • Vision may be blurry for a few hours
- • Mild headache or eye discomfort is common for a day
- • Anti-inflammatory drops prescribed for about a week
- • Follow-up exam in 1-2 weeks to verify opening remains patent
- • May need to continue glaucoma medications depending on your condition
