Understanding the Omni Surgical Procedure
OMNI® is a minimally invasive glaucoma surgery (MIGS) system that helps reduce intraocular pressure (IOP) in adults with primary open-angle glaucoma. It achieves this by targeting the eye's natural drainage system to restore proper fluid outflow. Unlike more traditional, invasive surgeries, it is performed through a micro-incision in the cornea and requires no permanent implants, contributing to its short duration and quick recovery time.
A Detailed Timeline: From Start to Finish
While the actual surgical time for an Omni procedure is remarkably short, the entire process—including pre-operative preparation and post-operative care—takes a bit longer. Knowing the complete timeline can help patients feel more prepared and at ease.
The Surgical Procedure: 10–20 Minutes
At the heart of the matter, the surgical part of the Omni procedure is very quick. During this time, the eye is numbed with topical anesthetic, and a microcatheter is used to perform two key actions:
- Viscodilation: Expanding the eye's drainage canal (Schlemm's canal).
- Trabeculotomy: Creating an incision to open the trabecular meshwork.
These two procedures effectively address the resistance points that cause pressure buildup. The efficiency of a single, specialized device and the micro-incisional approach are what allow for such a fast surgical time.
Pre-Operative Preparation: 60–90 Minutes
Your time at the surgical center begins well before the actual procedure. This preparation phase is crucial for ensuring safety and accuracy. It includes:
- Patient Check-in and Vitals: Standard intake procedures and a review of medical history.
- Dilation of the Pupil: Drops are administered to dilate the pupil, which helps the surgeon visualize the eye's internal structures. This can take 20–30 minutes.
- Topical Anesthetic: Numbing drops are applied to the eye to ensure a pain-free experience.
- Final Consultation: A final check with the surgical team to confirm the treatment plan and address any last-minute questions.
Post-Operative Recovery and Discharge: 30–60 Minutes
Following the brief procedure, patients are moved to a recovery area for observation. This time allows the effects of the anesthetic to subside and ensures there are no immediate complications. A member of the surgical team will review post-operative instructions with you and your caregiver, who is required to drive you home. The entire hospital stay, including preparation, surgery, and recovery, is typically completed within a few hours.
Factors that Influence Total Surgical Duration
While the 10–20 minute surgical time is a good general estimate, several factors can affect the total time you spend at the clinic:
- Combined Procedures: Omni is frequently performed in conjunction with cataract surgery. When combined, the total surgical time will be slightly longer, but the efficiency of performing both in one session is a major advantage for patients.
- Patient Specifics: Individual patient anatomy, the severity of the glaucoma, and other health factors can slightly alter the duration.
- Surgical Team Experience: While the Omni system is designed for ease of use, an experienced surgical team can contribute to a smooth and efficient process.
Comparison of Glaucoma Procedures
Understanding how Omni stacks up against other treatment options can provide valuable context. Here is a comparison of typical timeframes and invasiveness:
| Procedure | Avg. Surgical Time | Invasiveness | Recovery Time | Implants? |
|---|---|---|---|---|
| Omni (MIGS) | 10–20 mins | Minimally Invasive | Very quick (days) | No |
| Cataract + Omni | 20–30+ mins | Minimally Invasive | Very quick (days) | IOL only |
| Traditional Glaucoma Surgery | 45–60+ mins | More Invasive | Several weeks | Can vary |
| Glaucoma Eye Drops | Ongoing use | Non-invasive | N/A | N/A |
| Laser Therapy | 5–15 mins | Non-invasive | Very quick (hours) | No |
Long-Term Outlook: What to Expect
Following your Omni procedure, the initial recovery is fast, with most patients returning to their normal routine within a week. The ultimate goal is to achieve a consistent reduction in intraocular pressure, potentially reducing or eliminating the need for daily eye drops. Regular follow-up appointments with your ophthalmologist are crucial to monitor your eye pressure and long-term progress.

Conclusion: Fast and Effective Management
In summary, the core of the Omni surgery is a swift, 10–20 minute outpatient procedure. The total time spent at the surgical center will be longer due to necessary preparation and a brief recovery period. As a minimally invasive option, it offers patients an efficient and effective way to manage glaucoma, with the added benefit of a rapid return to daily life. Understanding the complete timeline can help you prepare for a successful surgical experience.
