Thank you, Cameron, and good morning to everyone listening. Thank you for joining us on our fourth quarter and full year 2021 conference call.
2021 was a year of continued progress and execution for LENSAR, and I'm proud of all that we've accomplished since becoming a public company in the fall of 2020, despite facing the lingering challenges associated with the global COVID-19 pandemic.
2021 represented a return to our historical growth trends as well as meeting our development milestones leading up to our 510(k) filing for ALLY in the first quarter of 2022.
Our full year revenue increased 31%, and procedures sold were up 37% over 2020. It's also an important metric to note, procedures were up approximately 22% in 2021, as compared to pre-pandemic levels in 2019, signifying a return to our historical trend of delivering 20-plus percent growth on an annual basis.
In addition to steady growth in procedure volumes, we saw increases in both system sales and lease placements for our current product offering, LENSAR Laser System with Streamline and IntelliAxis Refractive Capsulorhexis. This is yet another indication reflecting our continued demand and confidence from the surgeon community and the value of our leading-edge cataract surgery technology.
Even with the difficulty of placing capital equipment in new accounts, including the more time-consuming operating procedures and controls our surgeons and site space in the backdrop and uncertainty of the pandemic, we were successful in increasing our worldwide installed base of systems over 10% in 2021.
One of the key benefits to the gradual easing of COVID-related restrictions has been our ability to engage in more direct in-person sales and marketing activities with physicians as well as industry events. Even though we were successful in adapting our operations to whatever situation the pandemic presented, face-to-face interactions and the ability to visit with existing and prospective customers is beneficial to the process of demonstrating and realizing the benefits of our more highly evolved current femtosecond laser as well as to engage in more productive discussions regarding the substantial benefits and enhancements of the ALLY system.
As we entered the fourth quarter, our team scheduled several meetings and presentations around the AAO conference in New Orleans and ASCRS sponsored Aegean Cornea. LENSAR was able to leverage the growing appreciation of our current LENSAR system with our core feature technologies as well as the enhanced features and advancements in technology of our next-generation ALLY Adaptive Cataract Treatment System that we are planning to bring to femtosecond laser cataract surgical procedures.
Turning to ALLY. We recently achieved a major milestone with the submission and FDA acceptance of our 510(k) application and regulatory clearance of ALLY, as promised. Our application is now undergoing substantive review by the agency, and we are on track to launch ALLY in the second half of 2022 if cleared by FDA.
As we discussed in our press release announcing FDA acceptance of the 510(k), the submission is the first phase of a planned 2-step commercial release strategy. The ALLY Adaptive Cataract Treatment System, if cleared by the FDA, will be launched as the next-generation femtosecond laser.
This launch will be followed by an additional 510(k) application seeking clearance of the phacoemulsification features contained within the integrated ALLY system later this year.
LENSAR will begin commercialization of ALLY as planned with a controlled launch. ALLY will have the phacoemulsification device integrated as part of the system. However, the features will not be enabled for use until we receive FDA clearance on this aspect of the combined system.
We believe the staged approach allows for the most efficient, expeditious and clear pathway to commercialization for ALLY and, more importantly, puts the most advanced and most contemporary femtosecond laser in the hands of surgeons in 2022.
The majority of competitive femtosecond lasers currently in use are nearing the end of their useful life and are clearly vulnerable to replacement. Ophthalmic surgeons demand the most contemporary and advanced technology, not systems that lack substantive relevant enhancements that are based on technology more than a decade old. They want access to the most efficient and best tools in their hands because it provides the opportunity to deliver best practice outcomes for their patients and their practices.
Other than our current LLS, the first femtosecond lasers for cataract surgery entered the market as early as 2010, and they haven't evolved much from their initial state. These lasers lack the key features that are at the core foundation in the current generation LLS and in the ALLY Adaptive Cataract Treatment System.
LENSAR's laser system has been evolutionary to include a suite of 6 significant upgrades in the past 6 years, providing better technology to assist the surgeon in delivering consistently better efficiencies and outcomes, improving both the patients and surgeons' experience in cataract surgery.
Now we are moving to ALLY. ALLY is revolutionary, having the potential to address many of the limitations of current technology through its small footprint, significantly increase laser speeds in both the cornea and lens treatments that are part of the cataract procedure, enhanced ergonomics, superior imaging capabilities and includes advanced astigmatism management features. We believe that Ally sets a new standard for femtosecond laser-assisted cataract surgery with the potential to improve surgeon efficiency and enable them to deliver optimal outcomes for patients.
The first in-market dual-pulse laser is designed to significantly reduce the duration of treatments, cutting procedure time by up to 2/3. We look forward to the FDA review process and updating you on all of our progress as we move closer to a potential clearance decision.
While 2021 presented challenges, I believe we're on the verge of revolutionizing the cataract treatment market. We're at this juncture, thanks to the commitment, teamwork and support of the entire LENSAR team in working toward our collective objectives of continuing to be the technology leader in the industry.
Now let me turn the call over to Tom to cover our financial highlights for the quarter and year. Tom?
