Being interventional is about using every opportunity to manage glaucoma more effectively.
Interventional glaucoma (IG) offers a proactive strategy to preserve vision and protect patients’ quality of life, making early adoption a compelling priority for forward-looking ophthalmic practices. Harvard Eye Associates, in Orange County, California, was an early adopter of IG. “We’re always asking if there’s a better way to care for our patients,” glaucoma surgeon Savak “Sev” Teymoorian, MD, MBA, explained. That mindset paved the way for a shift toward IG.
How It Started
The limitations associated with relying solely on topical medications or traditional surgery, particularly in newly diagnosed glaucoma patients, prompted the Harvard Eye Associates team to explore alternative treatment options, including procedural pharmaceuticals, selective laser trabeculoplasty (SLT), and MIGS. Well-known challenges associated with traditional glaucoma therapy include poor adherence, inconsistent intraocular pressure (IOP) control, complex dosing schedules, physical difficulty administering topical medications, medication-related side effects such as ocular surface disease, and financial burden.1 Publication of the landmark LiGHT study, which demonstrated SLT was an effective first-line therapy for open-angle glaucoma, gave the practice the clinical justification to formalize its interventional strategy.2 “It gave us the confidence to move away from starting patients on drops by default,” said Dr. Teymoorian.
Around the same time, a selection of microinvasive glaucoma surgeries (MIGS) that could be performed independently or paired with cataract surgery emerged, and procedural pharmaceuticals such as iDose® TR (travoprost intracameral implant) 75 mcg (Glaukos) and Durysta® (AbbVie) further expanded the growing glaucoma treatment toolbox.3,4 “Over the past 5 years, this shift has been evolutionary. The result is an array of non-drop-based options to manage glaucoma more proactively, and now the data supports the model. We just have to keep executing it,” said Dr. Teymoorian.
How It’s Going
Dr. Teymoorian sees IG as a philosophical shift toward proactive management. “It’s not just about earlier treatment. It’s about earlier diagnosis, improved patient education, and using technology to stay ahead of disease progression,” he explained. Glaucoma is the second leading cause of blindness.5 Rather than reacting to structural damage after it occurs, the goal is to preserve functional vision by intervening sooner. “By taking a more proactive role and shifting some treatment responsibility from the patient to the physician, we can deliver more consistent care,” he said.
Interventional strategies often align with natural milestones in a patient’s visual journey. “For example, when patients are ready for cataract surgery, we can combine that with a MIGS procedure to better manage IOP and reduce reliance on glaucoma eye drops,” Dr. Teymoorian explained. “It’s about using every opportunity to protect vision in a forward-thinking way.”
Assessing Practice Patterns
Assessing current practice patterns is essential when considering a shift toward IG. “We often think we’re practicing a certain way, but when we actually examine the data, it may tell a different story,” Dr. Teymoorian noted. A clear-eyed review of metrics can reveal gaps, highlight opportunities, and identify barriers that may be limiting adoption. “IG isn’t defined by any one product or procedure—it’s a mindset. Changing that mindset requires alignment across the care team, including providers, patients, and even payers,” he said.
To support that shift, Dr. Teymoorian emphasizes the importance of documenting an ideal treatment protocol. “Everyone involved in glaucoma care needs to be on the same page. The patient is more likely to trust the plan when the messaging is unified between the optometrist and ophthalmologist,” he explained. At Harvard Eye Associates, regular meetings between ophthalmologists and optometrists help sustain this shared approach. “That shared protocol improves efficiency, reinforces trust, and ultimately leads to better patient care.”
A recently published IG treatment consensus protocol6 provides a stepwise procession of IG treatments, including rationale behind each step, and can help guide providers seeking to incorporate IG principles into their practices.
Practice Management Perspective
Harvard Eye Associates Chief Operating Officer, Arsen Grigoryan, MBA, COE, sees IG as a strategic imperative. Mr. Grigoryan, who started at the Orange County practice as an ophthalmic technician over a decade ago and continued to serve in various roles while advancing his education, approaches the evolution and execution of IG in the way he approaches everything in the practice: define the problem, identify the solution, and execute the strategy. He describes key steps to implement an effective IG model.
- Practice Assessment
“The first step was asking: what does IG mean for our patients?” said Mr. Grigoryan. “We had to stop and assess where we truly stood, such as what our current patterns were, how we defined ‘best care,’ and where we could improve.” Having worked on the clinic side, he recognized firsthand how patients struggled with medication adherence, side effects, and cost. “Drops can be a barrier,” he noted. “When patients can’t squeeze the bottle, forget to refill it, or get hit with sticker shock at the pharmacy, we’re setting them up to fail.” - Document Your Treatment Protocol
From a management perspective, consistency is key. Mr. Grigoryan underscores the importance of codifying the glaucoma treatment protocol. “When you define the clinical standard, you empower every member of the team—from technician to optometrist—to reinforce the same message. That alignment is essential for both trust and efficiency,” he explained. - Teach Your Teams
Grigoryan also emphasizes training. “You can’t expect uniform outcomes if people aren’t taught the same approach,” he said, noting the need to build internal systems that follow clinician recommendations. - Hold Yourself Accountable
Grigoryan stresses the importance of documentation as a mechanism for accountability: “Once you write down your ideal pathway, it becomes a benchmark. You start noticing where you’re falling back into old habits and where you can improve.” - Teach Your External Partners
The protocol also facilitates collaborative care. “We share our treatment approach with referring optometrists so they can start the conversation,” he said. “It makes the handoff smoother, and the patient feels supported instead of confused.” - Streamline Collaborative Care
With alignment comes efficiency. “When internal teams and external partners are on the same page, referrals become easier to manage, and we can provide better service with less administrative friction,” Mr. Grigoryan explained.
Act Now
From a clinical perspective, Dr. Teymoorian says the ultimate rationalization for implementing an IG model sooner rather than later is that early intervention preserves quality of life. “It’s simple,” he said, “by leveraging IG techniques before optic nerve damage occurs, we can help patients avoid visual field loss and maintain functional vision.”
From a practice standpoint, Mr. Grigoryan said the IG model alleviates downstream burden. “When patients rely on chronic drops, it leads to more refill requests, more prior authorizations, and more symptom-related calls, which can overwhelm staff resources. IG solutions like SLT and iDose TR relieve that pressure and allow us to redirect time toward delivery of care,” he explained.
Mr. Grigoryan also points out: “If you’re not evolving, you risk falling behind. What might have worked yesterday becomes imperfect today and unacceptable tomorrow.”
