Omni Glaucoma Surgery
Schlemm’s Canal Glaucoma Treatment with Omni
MIGS with the Sight Sciences Omni System in Austin, Kyle, Killeen & New Braunfels
When managing glaucoma, restoring the eye’s natural outflow system can reduce intraocular pressure (IOP) without the risks of traditional surgery. That’s exactly what the Omni Surgical System offers—a comprehensive MIGS approach that enhances multiple outflow pathways using one minimally invasive device.
At Westlake Eye Specialists, we proudly offer Omni Schlemm’s Canal-based MIGS to patients in Austin, Kyle, Killeen, and New Braunfels. These innovative procedures are performed by Harvard-trained glaucoma specialist Dr. Zarmeena Vendal, MD, who specializes in preserving vision with the most advanced techniques available.
What Is the Sight Sciences Omni System?
The Omni Surgical System is a single-use, handheld device that can perform three essential MIGS procedures within one session:
- Canaloplasty – To dilate Schlemm’s canal and improve aqueous outflow
- Trabeculotomy – To remove resistance in the trabecular meshwork
- Viscodilation – To gently expand both Schlemm’s canal and the collector channels
By targeting the eye’s natural drainage system in multiple areas, Omni can significantly reduce IOP—often without the need for daily eye drops or more invasive surgery.
How Omni Enhances Schlemm’s Canal
Schlemm’s canal is a circular drainage channel located in the front of the eye. In glaucoma, blockages within this canal or its nearby pathways can cause fluid buildup and elevated IOP.
The Omni procedure:
- Creates better access to Schlemm’s canal
- Dilates the canal and collector channels using a microcatheter
- Optionally performs a trabeculotomy to excise part of the trabecular meshwork
- Encourages natural fluid outflow through multiple resistance points
It’s a comprehensive yet gentle solution—especially for patients who may not yet need filtering surgery like trabeculectomy or tube shunts.
Who Is a Candidate for Omni MIGS?
Omni is best suited for patients who:
- Have mild to moderate open-angle glaucoma
- Are undergoing cataract surgery and want MIGS performed at the same time
- Want to reduce or eliminate their reliance on eye drops
- Prefer a non-implant approach (Omni does not leave a stent or device in the eye)
- Have had limited success with prior drop-based or laser treatments
A detailed evaluation with Dr. Zarmeena Vendal will help determine if Omni is your best next step in managing glaucoma.
What to Expect During the Omni Procedure
Omni MIGS is often performed alongside cataract surgery, though it can also be done independently in some cases.
Procedure Steps:
- The eye is numbed with topical anesthetic
- A microcatheter is inserted through a tiny corneal incision
- The catheter is guided through Schlemm’s canal to deliver viscoelastic fluid
- If trabeculotomy is included, a segment of trabecular meshwork may be removed
- The entire procedure usually takes 15–20 minutes
- No stents or permanent devices are left in the eye
Post-Procedure Recovery and Results
- Rapid recovery with minimal discomfort
- Vision returning to baseline within a day or two
- Significantly lowered IOP, often measurable within the first few weeks
- Reduced or discontinued use of glaucoma drops
- Fewer complications than with traditional surgery
You’ll return to Westlake Eye Specialists for follow-up visits to ensure healing and continued IOP control.
