Selective Light Therapy
Selective Light Therapy (SLT), also known as Selective Laser Trabeculoplasty, plays a critically important role in the treatment of glaucoma. Around the world, thousands of physicians are deploying the procedure as a primary therapy tool that stimulates the eye's natural healing response to effectively manage their patients’ IOP without the burn and scar tissue associated with argon laser trabeculoplasty (ALT).
- Lowers IOP as effectively as medication when used as a first-line therapy1
- Restores the outflow pathway naturally
- Dual role in diagnosing and treating glaucoma
- Pairs seamlessly across a range of MIGS procedures
Reduce IOP — as effectively as medication
SLT is an advanced, non-thermal nanosecond laser treatment that can achieve reductions in IOP as effectively as medication, without the associated side effects or compliance problems.1 SLT is also ideally suited for glaucoma patients who are frustrated with the effectiveness of their medications; it can play a role in reducing their associated financial and lifestyle burdens.
Particularly effective with non-compliant patients, SLT works by applying selective photothermolysis of the pigmented trabecular meshwork cells. This intervention stimulates the release of proteins and cytokines and the recruitment of macrophages to improve the circulation of aqueous humor through the meshwork and the inner wall of the Schlemm’s canal without causing thermal or coagulative damage.
Equivalent Efficacy to Medication
|Baseline IOP||24.5 mm Hg||24.7 mm Hg|
|Post-Treatment IOP||18.2 mm Hg||17.7 mm Hg|
A key tool in diagnosis
You can evaluate the result of intervention with SLT to estimate the location of the pathology. If the intervention is successful, the primary region of obstruction may lie within the trabecular meshwork, but if it is ineffective, then the primary obstruction may reside elsewhere. That’s why SLT can play a key role in helping both to understand a patient’s pathology and provide key information on the potential efficacy of future treatments.
Seamless pairing with MIGS
SLT pairs seamlessly with all MIGS procedures, including ABiC™ (ab-interno Canaloplasty), as both a preoperative diagnostic aid or as a postoperative adjunct, and can be deployed synergistically to reduce the need for further medication or future filtration surgery.
Ellex’s proprietary SLT technology delivers advanced energy control, a sharp-edged aiming beam and the industry’s fastest firing rate of three shots per second*. It's a capability that's being used every day by thousands of physicians around the world to visualize the trabecular meshwork in greater detail, and to perform procedures faster and with improved accuracy, delivering better patient outcomes - reliably, accurately and safely.

“SLT has the potential to become the go-to glaucoma treatment. Not only can SLT eliminate or at least reduce the need for drops, it can help to preserve vision and delay or even prevent complicated, invasive surgical interventions.”
