Thank you, Cameron, and good morning to everyone listening. Thank you for joining us on our first quarter 2022 conference call.
We have achieved an impressive start to 2022 by returning to our historical growth trends, as well as delivering on our previously-promised critical strategic milestone with the submission, and the FDA subsequent acceptance for substantive review our 510(k) filing for ALLY. Our first quarter revenue worldwide procedure volumes each increased more than 30% compared to the first quarter of 2021.
In addition to steady growth in procedure volumes, we continue to see increases in both system sales and lease placements for our current generation LENSAR Laser System with Streamline IntelliAxis Refractive Capsulorhexis by increasing systems placed on a worldwide basis to approximately 255 systems. This represents a 30-system increase from March 31, 2021.
These additional system placements and the associated year-over-year procedure increase represent a strong foundation upon which to launch ALLY, and continued validation of the core feature technology advantages of the current LENSAR System in comparison to other femtosecond lasers available in the marketplace. Furthermore, we intend to continue leading innovation by giving refracted cataract surgeons even greater technology performance and procedure efficiencies with ALLY.
Thereby, enabling them to provide highly optimized patient outcomes and provide an overall better patient experience in their cataract surgery procedures. These advancements and commitment to the continuous improvement of our device are at the heart of the reason why U.S.
based LENSAR Laser Systems performed twice as many procedures as the industry average. We have also made tremendous headway in broadening surgeon awareness of ALLY, mostly recently as measured and recognized at the ASCRS a few weeks ago.
I would like to highlight some metrics from the ASCRS meeting as it's arguably one of the largest and most relevant U.S. congresses in our field.
Attendance was significantly higher than last year with nearly 3,000 surgeons attending in person. Furthermore, LENSAR is well-represented with eight podium presentations demonstrating improved patient outcome and the management of astigmatism with reproducibility and precision that is not seen with manual and other laser technologies.
This provides LENSAR surgeons the opportunity to broaden use of their lasers to treat more patients, because they have the confidence that they can deliver on their patients' acceptance in these advanced cataract surgical procedures. We also had the opportunity to invite attendees to LENSAR experts meeting, which consisted of three comprehensive sessions covering a deep dive and the user experiences with our current LLS, new clinical data, and review of the first human cases performed with ALLY.
For the first time, we opened attendance to include a small group of non-LENSAR KOLs interested in the adoption of LENSAR with ALLY. We are thankful to the surgeons that presented their results and shared their experiences, as well to all the attendees.
The turnouts for these interactive sessions was very encouraging, and expanded awareness of LENSAR System's capabilities and the ability of our system to play a key role in facilitating better patient care. Over 140 ALLY demonstrations in total were completed.
Over 120 surgeon demonstrations were performed with 55% of these demos conducted for non-LENSAR customers. Market Scope recognized the LENSAR booth as one of the busiest at the ASCRS, as gratifying recognition of our commitment to delivering cutting-edge technology and the enthusiasm surrounding ALLY.
We also achieved a major milestone in the company's history with the submission and subsequent FDA acceptance of our 510(k) obligation for regulatory clearance of the ALLY in February. Our application is undergoing substantive review by the FDA.
And if cleared, we are on track to launch ALLY in the second-half of 2022. We look forward to continued and productive interactions with the FDA and our filing.
Now more than ever, we believe that ALLY represents a next grade innovation in refractive cataract surgery. It appears this thought is shared by a number of surgeons that were excited to demo ALLY for the first time.
ALLY has the potential to be the first platform in the market to combine a next generation dual pulse femtosecond laser with a world-leading Swiss-made phacoemulsification technology in a fully integrated system, allowing surgeons to prep the patient wants to perform a sterile flax and cataract procedure. The significantly faster scanning and laser treatment time, and not having to move and re-prep the patient, demonstrated that our patient treatment experience to-date indicated a time savings of 10 minutes per case.
ALLY is a transformative system that integrates current LLS core features, including cataract density imaging, customized fragmentation and energy settings, optimized incisions with proprietary astigmatic guidance technology to adapt to every patient condition, surgeon treatment preference in the work environment. I look forward to the remainder of 2022 at LENSAR as we have been able to build off the momentum generated in 2021, and the excitement surrounding ALLY and the SDRS, is confirmation of our beliefs that we're on the verge of revolutionizing the cataract surgery market.
We look at this excitement as a strong indicator that our commitment to delivering substantive and meaningful advancements is beginning to pay off. We look forward to updating you on our ALLY filing in the coming quarters.
And now, I'm going to turn the call over to Tom to cover our financial highlights for the quarter. Tom?
Tom Staab
Thank you, Nick. Our first quarter 2022 financial results are included in our press release issued earlier this morning, but I'd like to take this opportunity to expand on that information by adding some color to those remarks.
Revenue was $9.3 million in the first quarter of 2022, compared to $7 million in the first quarter of 2021. All individual components of revenue, product, lease, and service increased from the first quarter of 2021.
It was a very strong quarter for us with total revenue increasing 33% over the first quarter of 2021. The increase in 2022 total revenue was primarily driven by increased procedure volume.
In the first quarter of 2022, there were 38,901 procedures sold, compared to 28,122 procedures sold in the first quarter of 2021. Our procedure volume increased 38% over the first quarter of 2021.
Gross margin for the quarter was $4.7 million or a 50% gross margin percentage and represents an approximate $800,000 increase compared to the $3.9 million realized in the first quarter of 2021. By all measures, the first quarter of 2022 was a strong quarter for us, with a 33% increase in revenue and a 38% increase in procedures, both representing impressive performance.
Congratulations to our team for such an outstanding quarter. Looking to the rest of the year, 2022 represents a transition year for us and we expect our gross margin percentage for the year to approximate 50%, with the latter part of the year having a higher gross margin percentage than the first-half of the year.
The transition of our manufacturing from our first generation system to ALLY and supply chain challenges which include difficulty in obtaining inventory, and a higher cost of raw materials lead us to expect a lower gross margin percentage in 2022 than percentages achieved previously. We expect annual gross margins to begin to improve in 2023 and continue to improve in future years as we are able to realize manufacturing and purchasing economies of scale and absorb overhead more efficiently.
In addition and relatively unique to this quarter, our Q1 2022 gross margin was negatively impacted by higher service costs. Approximately $600,000 was incurred to replace expensive parts in several installed systems, the replacement of these expensive parts and the magnitude that occurred in the first quarter is considered unusual.
Total operating expense for the first quarter of 2022 was $11.4 million, compared to $9.1 million in the first quarter of 2021. The increase in operating expenses was largely due to an increase in R&D activities as we filed our 510(k) for ALLY and purchased inventory components and built ALLY prototypes for which these costs were expensed R&D and will be until we receive FDA clearance on our 510(k).
Also included in the operating expenses were non-cash stock based compensation expenses of $1.6 million and $2.3 million in the first quarter of 2022 and 2021 respectively. The increase in R&D expense for the first quarter of 2022 was related to additional cost for the continued development of ALLY as well as materials purchased for the manufacture of ALLY, which amounted to approximately $2 million.
Accordingly, our R&D expenses were somewhat inflated in the first quarter due to these inventory purchases. We expect this situation to continue in the second quarter of 2022 and up until we obtain clearance on our 501(k) filing.
Net loss for the quarter was $6.7 million or a $0.67 loss per share compared to $5.2 million or a $0.56 loss per share in the first quarter of 2021. Adjusted EBITDA for the first quarter of 2022, which excludes the effects of stock-based compensation expense mentioned earlier, was a $4.2 million loss compared to a $2.2 million loss in the first quarter of 2021.
As a reminder, we use adjusted EBITDA to evaluate our cash flow and profit from operations. When you consider or deduct R&D expense, we have a positive cash flow and profit from our operations.
As of March 31st, 2022, we had cash and cash equivalents of $29 million as compared to $31.6 million at December 31st, 2021. Cash utilized in the quarter was $2.6 million.
With $29 million in cash at March 31st, a cash burn of less than $10 million for fiscal 2021 in our ALLY 510(k) accepted for review by the FDA, we have a strong balance sheet in which to launch ALLY and have positive momentum going into the second quarter. Now, I'd like to turn the call back over to our Operator, Jerome, and we look forward to taking your questions.
Operator
[Operator Instructions] Your first question comes from the line of Ryan Zimmerman with BTIG. Your line is open.
Ryan Zimmerman
Good morning. Thanks for taking the questions.
I just wanted to start with talking about installed base and utilization a little bit. And it continues to grow really nicely, and the procedure volumes are very encouraging to see.
I am just curious, Nick, if you could kind of talk about -- I mean, some of your users have been with the system for a while, kind of how their utilization looks on their system relative to newer users? And kind of what it takes for those newer users to ramp up?
I think would be helpful to understand. And if you could also just comment on kind of -- I mean the procedure volume is again very encouraging, how is that trending in the April and early May?
Nick Curtis
Yes. Thanks, Ryan.
Those are really good questions. So, we kind of look at things like once a customer has had a system for, let's just call it, six months because there is a ramp up period.
And the ramp up period usually consists of getting into a new account, getting the staffs trained -- support staff is very important, getting the clinical operators trained, getting people comfortable with the system, getting the doctors trained to the point where they understand the features and the differences primarily between the LENSAR System and the system that they may have been using prior to the LENSAR [IN] [Ph]. And so, there is sort of ramp up period, which in that first 90-day period where we look at going from very little revenue to where we were generating good procedure volumes.
After that 90-day, they start to get to the procedure volumes that they were at prior to putting LENSAR in there, and then by the time we are in that about four to six month -- four to six months out, we're usually operating very efficiently within the practice and beginning to see procedure growth. As we continue to evolve the system by adding preoperative surgical devices, and adding other efficiencies, and whatnot, we see that existing accounts as they continue to be more comfortable.
They grow within that as well. They either grow organically through the 3% growth rate annually that comes just from cataract surgery in general.
And then, what's been happening is that conversion rates to these types of procedures and particularly in the area of management of astigmatism continues to grow within the practice as they continue to optimize their nomograms and whatnot. You know, given any real shutdown, to your second question, any real slowdown as a result of any COVID variances or something unusual that we can't predict, we see that procedure volumes will continue to be strong, particularly as there -- it appears that there still is a backlog from COVID in just surgical -- available surgical time for doctors to be able to do their cases.
So, we would expect that at least from a surgical procedure perspective that we will continue to be strong there.
Ryan Zimmerman
And very encouraging -- all right.
Tom Staab
And Ryan, just one other thing to add to Nick's comments is, outside the United States, procedure volume was really, really strong in the first quarter. As you go into May or April and early May, outside the United States is backed off a little bit, but the U.S.
has picked up a little bit and the U.S. is 50% of our volume.
All in all, you're seeing a slight downtick from the first quarter, but it's still a very robust procedure volume, and you'll see procedures increase from the second quarter, or we would expect you'd see that they would increase from the second quarter of '21.
Ryan Zimmerman
Very helpful, thanks for taking my questions.
Tom Staab
No problem, Ryan. Thank you.
Operator
And your next question comes from the line of Danielle Antalffy with SVB. Your line is open.
Danielle Antalffy
Hey, good morning, guys. Thanks so much for taking the question.
Congrats on a really strong quarter and a strong showing at ASCRS. Nick, I was wondering as you think about ALLY, thank you guys so much for the data on number of demos and particularly new or non-current users, so, as we think about that and think about the upcoming FDA approval of ALLY, how do we think about the rollout there?
I spent some time at the [booth] [Ph], I can see that the anticipation is high. So, I'm guessing a lot of these doctors are just asking, "When can we get one?"
So, help us understand how you guys are approaching the rollout of ALLY once it's approved.
Nick Curtis
Hi, Danielle. Thanks for getting on the call today, and thanks for coming by at ASCRS and seeing the system as well.
So, we obviously are excited, and we know that surgeons are very enthused to want to see ALLY in their practices sooner rather than later. That said, it would be imprudent on our part, particularly with a brand-new piece of technology that's moved from an R&D into a full [indiscernible] manufacturing, that we're cautious and that we control our launch.
And so, we're planning on what we refer to as 10 friends and family sites when we begin the rollout with ALLY shortly after the clearance. And that will consist of, of course, some existing LENSAR users, and a few of new KLL users that we've been working with, along with our current user KLLs in sort of this whole process to begin with as we move forward.
And so, we're looking at putting those 10 sites in place, and then following those sites for a few months in order to be comfortable that everything is performing exactly how we expected that we understand what we're doing from a training perspective, that the surgeons are adapting to it, that we're getting what we advertise, so to speak. And then, we'll expand into in additional phase, which from there looks to be another somewhere between 10 and 20 systems, and so, before we get into sort of full launch mode in 2023.
Danielle Antalffy
Got it. Okay.
So, that was my next question. So, right to think about this as 2022 will be more measured, '23, you can let the [indiscernible].
Nick Curtis
Yes. Assuming that we don't have continued issues as it relates to to supply chain force, but yes.
Danielle Antalffy
Sure. Okay, okay.
And then, when thinking about utilization, just following up on Ryan's question there, utilization on the current system versus how we should think about utilization on ALLY. And I know it hasn't launched yet, so I guess TBD, but theoretically, you have to think that utilization could move significantly higher with ALLY, given the improved efficiencies on the system.
So, just how are you guys thinking about it, even theoretically or qualitatively would be helpful? Thanks so much for taking the questions.
Nick Curtis
Hey, no problem. Those are great questions, and obviously things that we're very keen on wanting to get answered as quickly as possible as well.
So, we're working in a couple of different situations here, because you may recall that in past, I've said that most of these systems today, no matter what company they're from, sit outside of the operating room. And that with ALLY, you have the opportunity to move into the operating room, if you want to take advantage of full efficiency of the system to perform a sterile procedure to be able to switch even if you weren't using the LENSAR phaco system and you're using whatever phaco system, you're using today to switch from the Femto to the phaco in a sterile environment, certainly, from a flow perspective becomes much more efficient and faster.
And so, we see this happening in part of what we're going to be doing in these 10 accounts is that, you'll likely have a few accounts that will continue to put the laser where they have the laser today in order to just really become comfortable with the system. And the fact that it is that much faster and efficient.
And then, you'll have a few of these accounts that will put them right into the operating room. And we have a private equity group, one of the private equity groups that we're working with actually wants to study and to do some flow analysis with us, because they're interested in ALLY on a much broader basis for more of their practices, and on ORs if you will, so we'll have an experiment where we put one in each of two operating rooms.
And we'll see how much faster and more efficient and better use of the human resource as well, in terms of transporting patients and whatnot that we do. I alluded to the fact that in our first clinical patients that we had done, the doctor was reporting that we were saving in the treatment time, about two minutes, and in the transport time and prepping the patient another eight minutes, or about 10 minutes with each patient in their cataract journey there, and so really, the next months are going to be in those three scenarios, really testing those things out.
Does that answer your question?
Danielle Antalffy
It sure did. Thank you, Nick.
That was so helpful. Thanks, guys.
Operator
Thank you. I'll hand the call back to Nick Curtis.
Nick Curtis
Thank you, everybody for joining our call today. As you can tell, we're quite enthusiastic about what's going on here at LENSAR.
We certainly appreciate the fact that you're interested as well, and we look forward to continuing to update you as we make further progress.
Operator
All right, thank you. And that concludes today's conference.
Thank you all for joining. You may now disconnect.
