Selective Laser Trabeculoplasty (SLT) is a non-invasive laser treatment used to lower intraocular pressure (IOP) in patients with glaucoma.
SLT targets the trabecular meshwork—the eye’s natural drainage system—to improve fluid outflow and reduce pressure.
SLT uses low-energy laser pulses to selectively target pigmented cells in the trabecular meshwork.
This process:
Unlike other laser treatments, SLT does not cause thermal damage to surrounding tissue
Often used as:
| Feature | SLT | Eye Drops |
|---|---|---|
| Compliance | High | Variable |
| Side Effects | Minimal | Possible |
| Duration | Long-lasting | Ongoing |
| Convenience | One procedure | Daily use |
Many modern systems combine both SLT and YAG in one platform
Popular for clinics needing both glaucoma and capsulotomy capabilities
Designed specifically for glaucoma treatment workflows
SLT is increasingly being used as a first-line treatment for glaucoma, especially in patients who struggle with medication compliance.
This shift is driving increased demand for SLT-capable systems
What is SLT laser used for?
SLT is used to lower intraocular pressure in patients with glaucoma.
Is SLT better than eye drops?
For many patients, SLT offers a more convenient alternative to daily medication.
How long does SLT last?
The effects can last several years but may vary by patient.
Can SLT be repeated?
Yes, SLT can often be repeated if needed.
