Thank you, Trip. Good afternoon. Thanks for joining us today. I'll provide updates on our business progress. Fouad will provide details on the first quarter financials. We will open the call for questions. In the first quarter of 2023, we generated 13.7 million in total revenue, growth of 2% compared to the prior year period. Growth was driven by our Cyclo G6 glaucoma laser platform. Offset by a slight decline in the retina sales. In our glaucoma business, Cyclo G6 revenue increased by 4% year-over-year to 3.7 million. We continue to experience solid adoption of the G6 technology worldwide, as 61 systems were sold in the quarter compared to 56 in the first quarter of last year.
In the U.S., we were pleased to have achieved a 19% increase in G6 probe revenue, driven by ASP increases and a 7% volume growth. Worldwide glaucoma probe revenue grew by 6% despite a decline in units to 13,800 probes in the quarter, a 6% decrease from the prior year. Quarterly, international probe volumes remain volatile. This first quarter dip following record high volumes in the fourth quarter. Embedded in this volatility is a relatively flat multi-quarter volume trend. The international opportunity for MPTLT, that's MicroPulse Transscleral Laser Therapy, adoption is very large, and we believe its safety and efficacy will drive long-term penetration. We're focused on returning to solid growth internationally through our partners. We saw the Cyclo G6 rollout in China benefit from the COVID reopening, with order activity increasing late in the first quarter.
Underlying demand in international markets remains strong, as shown by continued strength of international system sales, and we expect a return to probe growth for the rest of the year. We continue to have confidence we will execute on the significant growth opportunity for G6 in the moderate severity glaucoma patient. To propel G6 utilization and adoption, we continue to focus on 4 key initiatives. First is advancing physician education by increasing awareness of proper dosing and patient selection. Second is identifying and targeting comprehensive ophthalmologists who see most of the moderate stage pre-incisional patients. Third, adding users at surgery centers by capitalizing on those that already have G6 systems. The final initiative is expanding clinical evidence to drive adoption of MPTLT. These initiatives are targeted to address the current barriers to greater adoption and growth.
User variability in technique and procedure protocols can lead to suboptimal results, forming the perception that the technology and procedure have a limited role. Since MicroPulse TLT originally evolved from the late stage treatment methodology of cyclophotocoagulation intended to reduce production of aqueous fluid, there's still a perception that this is the appropriate patient profile. To address these views, we sponsored the clinical consensus panel and are educating the market on conclusions around dosing and applicable patient recommended by the group. Another challenge we found is that surgeons' natural inclination is to sweep too fast during procedures, which leads to underdosing and is counter to the best long-lasting outcomes. We launched and continue to roll out our Sweep Management Software for G6 systems to aid in proper and consistent technique that can be reproduced across any user.
Surgeon feedback on the simplification and clinical outcomes generated using software are very positive. We're confident improved sweep speed optimization will generate improved clinical outcomes and durability, ultimately leading to greater utilization of our procedures. We continue to focus on educating providers on the benefits of MicroPulse technology use within a broader patient volume, specifically as it pertains to pre-incisional moderate stage patients and post-cataract surgery patients who may or may not have had a concomitant MIGS device used to treat their intraocular pressures. As happens with all treatments in this progressive disease, eventually pressures rise requiring additional treatment. MicroPulse TLT durability and repeatability enables avoidance or significant deferral of more aggressive, higher risk surgical glaucoma interventions. Another opportunity for further penetration in the market is to drive G6 adoption by comprehensive ophthalmologists. This group of providers usually diagnose and treat patients with earlier stages of glaucoma.
There are 5 times more comprehensive ophthalmologists than glaucoma specialists, and 10 times more moderate than advanced stage glaucoma patients. This past week, we had a very productive conference at the American Society of Cataract and Refractive Surgery meeting in San Diego, engaging with key opinion leaders, customers, and prospective customers. We were encouraged by the many comprehensive ophthalmologists at our booth wet lab training sessions, where we introduced and educated them on the benefits of the IRIDEX product portfolio. The early clinical experience using appropriate treatment parameters guided by Sweep Management Software has given us confidence to design and launch a larger scale multi-center prospective trial to prove the safety and substantial effectiveness of MicroPulse TLT for moderate stage glaucoma patients.
For example, a recent single center prospective study with three arms of escalating dosing achieved very strong early results of 31%-44% intraocular pressure reduction with excellent safety in all three arms. We're looking to build on these results to generate more substantial data that can validate true clinical value proposition. We're conducting a series of meetings with our KOL guidance group to identify the preliminary study protocol and identify appropriate research centers interested in participating. Our target is to begin enrolling patients in the study by year-end and look forward to sharing the details of the study once formalized. We believe a definitive multi-center study on the right targeted moderate stage patient profile would significantly support increased G6 adoption and utilization by a broad range of clinicians treating these patients.
As we look at the remainder of 2023, we expect to improve the growth rate of our glaucoma business and increase utilization. We are reiterating our guidance and continue to expect to sell 65,000-67,000 probes, representing growth of 9%-12% compared to 2022, and expect to grow the G6 installed base by 225 to 250 systems. Turning to our retina business. In the first quarter, retina performance was largely in line with our expectations on sales of $7.2 million. A slight dip compared to the prior year, with U.S. retina growth offset by modest international weakness. Internationally, our distributors are managing inventory more tightly, which has introduced more quarter-to-quarter volatility.
As we've broadened promotion from the limited launch of our new PASCAL platform, customers are responding, and we're seeing strong interest in the new platform. Incorporating MicroPulse technology in the integrated PASCAL system with half the footprint offers clinicians expanded treatment capabilities that can fit in nearly any size office. While interest is solid, we have seen signs of lengthening decision cycles amid the challenging macro environment, causing customers to be more methodical with their capital purchasing decisions. Our plans are progressing to achieve additional international regulatory approvals throughout the year to expand the commercial launch globally. FDA clearance for our other major platform for the single spot IRIDEX 532 laser and IRIDEX 577 laser keeps us on track to commercially launch the platform mid-year in the U.S., and we look forward to sharing updates on that progress.
To summarize, the start of the year was productive for IRIDEX, highlighted by 19% first quarter year-over-year growth of U.S. glaucoma probe revenue. We continue to build the foundation for further glaucoma market adoption and sustain long-term Cyclo G6 growth. It's hard work, requires focused selling and clinical support activities, increased marketing communication of our clinical benefits in the treatment paradigm, and our investments in the larger scale multi-center prospective trial to further our clinical evidence base. Looking ahead, we expect to increase our growth rates and remain confident our current cash balance is sufficient to execute our multi-year growth initiatives. On that note, we believe cash usage in the first quarter was high watermark for the year and not reflective of quarterly cadence in 2023. Fuad will detail more specifics of cash management expectations later in the call.
Now, I'd like to turn the call over to Fouad to cover the financial results.
Thank you, Dave. Good afternoon, everyone, thank you for joining us today. I would like to begin by reviewing our financial performance for the first quarter of fiscal 2023. Starting with revenue. Our total revenue for the first quarter of 2023 was $13.7 million, representing a growth of 2% compared to the first quarter of last year. Moving on to product revenues. Total revenue from the Cyclo G6 product family in the first quarter was $3.7 million, up 4% versus the same period in 2022. We sold 13,800 Cyclo G6 probes in the first quarter, a decrease of 6% from the prior year period. Note that this decline is driven by ordering volatility of our international distributors following a record fourth quarter.
We sold 61 Cyclo G6 systems in the quarter, compared to 56 in the prior year period. Our retina product revenue in the first quarter was $7.2 million, a decline of 1% from the prior year period. Other revenues, which include royalties, services, and other legacy products, increased 11% to $2.8 million in the first quarter of 2023 compared to the same period in 2022 on substantially higher revenue from our other legacy products. Our gross profit for the first quarter of 2023 was $5.9 million, relatively unchanged from the same period last year. Gross margin was 43.3% compared to 44.6% in the first quarter of 2022 on slightly lower overhead absorption in the current period.
Operating expenses for the first quarter were $8.3 million, flat compared to the same period last year. Our net loss in the first quarter of 2023 was $2.1 million, or a net loss of $0.13 per share compared to a net loss of $2.4 million or $0.15 per share for the same period in 2022. We ended the quarter with cash and cash equivalents of $11 million, representing cash usage of $2.9 million during the quarter. The cash usage in the first quarter includes inventory purchases of approximately $1 million related to the rollout of our new product launches, including our newly launched Gen M product and certain non-recurring capital expenditures.
As you may recall, last year we increased inventory by $4 million to proactively manage the tighter supply chain, thus avoiding manufacturing interruptions. This year, we plan to unwind a good portion of that inventory build into cash and onto the balance sheet. Additionally, following the completion of our new retina product development cycle, cost efficiencies in the cost of goods from the introduction of the new products and certain cost reduction programs, we expect to meaningfully reduce our quarterly cash usage. We believe the inventory reductions, along with lower quarterly expenses, should result in significantly lower cash usage through the second half of 2023.
In terms of numbers, we expect these planned cost reductions to deliver $1.5 million of savings in the second half of 2023, thereby reducing our cash usage from operations from an average of $1.3 million per quarter in 2022 to approximately $750,000 per quarter in the second half of 2023. Additionally, we also expect to release approximately $1.5 million of cash from the inventory reductions in the second half of fiscal 2023. In conclusion, we reiterate our guidance for 2023. We continue to expect total revenue for fiscal 2023 to be $57 million-$59 million. G6 probe unit sales are expected to range from 65,000-67,000, and Cyclo G6 Glaucoma Laser System install base is expected to expand by 225-250 units.
With that, Dave and I would like to turn the call over to the operator for questions. Operator?
Thank you. As a reminder, to ask a question, you will need to press star one one on your telephone if you're not already. Please stand by while we compile the Q&A roster. Our first question comes from the line of Tom Stephan of Stifel. Your question please, Tom.
Great. Hey, guys. Thanks for the questions. I'll start with G6 system shipments. Continue to post solid numbers there. Dave, can you talk about maybe the types of accounts you're selling into, their profiles, and what utilization looks like in these more recent additions to the install base?
Sure, Tom. The international sales are harder to specifically categorize in terms of those parameters. As you know, we sell to distributors first, some sub-distributors below them and then end customers. In general, to characterize, it's new capacity in a center typically sold to surgery centers, some hospitals, but probably, I'd say we're probably 80% surgery centers versus hospitals. It's new adoption in general. We are not yet seeing a significant addition of second units at a site that has a unit. The utilization is still, you know, in single digits per month on average. The capacity requirement is the capacity available is still quite high.
We do see, for example, in the United States, larger systems that might have a central primary office and then satellite offices, either in suburbs or different parts of cities, add units to put the capacity in those locations. In general, we're seeing the primary demand coming from new adopters of the technology and new sites where it hasn't been available. Just as an aside, you know, we're also focused on adding users at sites that have a laser system already, and that's a piece of our growth that doesn't show up in systems placements, but can show up in utilization.
Got it. That's helpful. If I can stick with G6, I wanted to ask about the probe growth guidance. Great to see it left unchanged and your high level of confidence. You know, U.S. probe growth in the quarter, I think you said was up only 7% year-over-year, and OUS clearly down a decent clip, and I get that there's some volatility there. Within the context.
Right.
-of your full year guidance of the 9%-12% growth, where does the US stand in that versus the OUS? You know, I'm just wondering how high above that range I'm assuming the US is, and maybe how achievable that is, given 1Q in the US only grew 7% year-over-year.
Yeah. Well, in our guidance, formulation, we anticipated that we would build that usage over the course of the year. While it would have been nice to have had a higher, number than the 7% growth in the U.S., we feel like we will build over the course of the year. There, you know, there's some degree of back-end loading to that we build over the course of the year and we see significantly higher, usage in the, in the later quarters. International volatility is, you know, it's a little frustrating, but it is what it is. It's a little harder to predict. There are no core issues with usage or end customers. We feel like the, you know, the challenge there has been the varying levels of inventory at distributors.
You know, for example, one of our largest distributor as their fiscal year-end at the end of the first quarter. Most companies, them included, target, you know, minimizing inventories, receivables, maximizing cash, and that can lead to kind of the kind of volatility that we see. The short answer is, we think all of the elements that we're focusing on to drive adoption and growth are progressing, and we think we can hit those numbers.
Got it. That's helpful. Last one for me. I wanted to ask just about competition. Maybe Dave, can you discuss your view on the competitive landscape in glaucoma, most notably the MIGS space? You know, now there's a standalone stent out there on the market, and a drug delivery implant potentially coming. How are you thinking about the potential long, I guess, longer-term impact on G6, if any? Thanks.
Yes. First of all, there are a lot of different companies selling a variety of MIGS devices. You know, from what we've seen and heard from our customers, the vast majority remains in the concomitant with cataract procedure, where there's no new incision needed for the MIGS device. We're not hearing an increase in standalone usage. We know that companies are out promoting it, in that sense, it's competitive because they're asking customers to use their device in a patient where we think we're more appropriate. You know, the difference between making an incision and not making an incision is significant, both to the patients as well as to the physicians.
You know, we continue to hear a strong preference, you know, for the same safety and efficacy to end up with a non-incisional approach. We're comfortable with that positioning. The competitive information flow in this space is intense. There's a lot of companies, they have, on average, more reps than us. You know, the number of reps speaking about some type of a MIGS device versus the contacts from our group is quite large. That's a challenge, and we address that by focusing on our specific cohort of targets per territory and taking them down their pathway and working with them through their process of gaining confidence and adopting the procedure.
We think with those kinds of targeted execution and the increases that we should be able to achieve with those customers, that leads us to the pro-growth guidance that we settled on for the year.
Makes sense. Thanks.
Thank you. Please stand by for our next question. Our next question comes from the line of Scott Henry of Roth Capital. Your question, please, Scott.
Thank you. Good afternoon, guys. A 2 questions. I'll start with G6. Dave, we've talked about this before, but I think it's a good time to bring it up again. You're getting a good number of systems out there, to get to the kind of compounded growth rates of, you know, to get to double-digit and high double-digit, we need to see probes per system. That metric, you know, has to go up because then you get the compounding of new systems, plus the current systems are being utilized more. Yeah, obviously it didn't go up in Q1, some noise there, and it looks like it's going to trend upward in the rest of the year.
How you think of that probes, probe utilization per system, and do you feel like you can get that going in a positive direction? Lately, it's been going kind of flat, which still grows, but not to the hyper levels that we've seen in the past.
Right. Our focus is on the adoption by doctors across the appropriate patient base. I commented a bit about how, you know, the initial, I'll say the initial application is a smaller group of patients in the later stages, and then people gain confidence in the procedure, the safety profile, and can expand toward more moderate stage where there are many more patients. In combination, adding a higher cohort of comprehensive ophthalmologists who see most of those moderate stage patients is the avenue to grow the average usage. We also have seen, I'll say, some frustration from customers if they're not following the parameters and effectively conducting the procedure that they're not getting the outcomes or the durability.
Safety profile has been excellent, but if they're not getting the outcomes or the durability, then they back away from usage. Those crosscurrents lead to a net lower usage rate, and that's what we think we can combat. We focus on those accounts who may have declined and understand what may have driven that. We focus on our target accounts to grow and really drive that adoption in a broader set of patients than really the late stage, well, what else are we gonna do with this patient? We think the combination of those two things will get us up into these higher growth rates. It's a process. It takes time. It takes time for them to do enough patients and then follow them for a period of time to gain confidence in outcomes and durability.
We focus on that, recognizing that, you know, that it's not a step function. That's going well in terms of the responsiveness of the customer base, but it takes time to build.
Okay. Thank you for the color on that. Shifting gears to retina. When you think about that segment, I guess two-part question. One, how do you think about the long-term growth? I mean, is it a 5% category growth, or how do we think about that? Then in the short term, might it be a little slower with the economic environment and perhaps some challenges in capital equipment? Do you see the short term a little tougher than the long term? You know, where is that long term?
Yeah. We think long term, Well, the industry growth rate worldwide is some of the research publications that look at that kind of thing, they keep it in the kind of the low single digits, mid to low single digits. We think we can grow at that rate and potentially a little higher as we get our new platform proliferated across the worldwide market opportunity. You know, we're in the U.S. with the platform and the PASCAL scanning laser. About to get the second platform into the U.S. Then second half of the year, we'll start receiving some of the clearances on the PASCAL platform to broaden that usage. We think that there are opportunities to grow maybe above market rate.
You know, we're a substantial share, and leader in that marketplace, so, you know, that's generally governed by the just the overall growth of the marketplace. Then in terms of the the short term economic we'll call it uncertainties, I think we are seeing people be more deliberate in their process, you know? What we are not seeing is people saying, "Yeah, we've changed our capital budgeting for the year and, you know, we're not gonna buy as much as we had intended before." That's not happened yet. We're just seeing the cycles, the selling cycle expand and people being a bit more thorough and deliberate in how they how they do their purchasing.
Internationally, we're seeing the distributors really try to lean out on inventory, and so that kind of puts a bit of a dampener if you've got some inventory, drawdown in the distributor base, along with, their sales to end customers maybe being a little slower.
Okay. Great. You know, you talked about that other line and about we were gonna get this kind of hit. The numbers look pretty good. I mean, it looks about as strong as it's ever been. Should we expect that to roll over at some point, or how do we think about that?
Yeah, that's more of a second half of the year phenomenon. You're referring to the reference we made in the guidance portion of?
Yeah
revenue, where we do have royalty income, and that patent is expiring and the royalties will go down. That will happen in really more in the second half of this year. We included that comment because the guidance is annual, so we that's obviously gonna be a component of the annual result. That's the nature of that. Then, in the other category, we did see some strength there in our other products, which are the, you know, there's a number of things that are either legacy that we expect to subside over time or, you know, some items that are discontinued and those are the kinds of products that are in other, in addition to the royalties and the deferred revenue recognition items.
we did see some strength in some of those products, which is quite encouraging. one of those products is a probe that's actually used in glaucoma. you know, we think that really offsets somewhat the significant disappointment that we had in total units of OUS glaucoma probes. in general, that's a, you know, relatively stable external category to the glaucoma business. this happened to, you know, have a positive divergence on that one, you know, maybe slightly offsetting the negative in the inventory shifts that were experienced in the first quarter.
Okay, great. Final question. It looked like G&A was a little high in the quarter. Any trend there or any noise? How should we think about that?
Yeah, no, there was certain one-time legal expenses just on the corporate side, you know, proxy related stuff to get ready for that and some IP related expenses that usually come in at the beginning of the year. Essentially that I don't expect that trend to continue. I think we should be closer to a $2 million run rate on G&A going forward.
Okay, great. Thank you for taking the questions.
Thank you. I would now like to turn the conference back to David Bruce for closing remarks. Sir?
Thank you, operator. Thank you, for the questions. Thanks to everyone for participation in the call this quarter. Thank you.
This concludes today's conference call. Thank you for participating. You may now.
