Faced with growing elderly populations around the world requiring cataract and vitreoretinal surgeries, limited growth in surgeon capacity, and declining specialised staff, ophthalmic manufacturers are pushing the boundaries of engineering to develop innovative technologies.
Alcon is one of those companies. With a significant team of engineers, the global leader is focussed on addressing core challenges facing ophthalmic surgeons by developing technologies that are easier, faster, more efficient, and safer.
At Alcon’s recent Focus meeting in Sydney, mivision sat down with Seba Leoni, President International Surgical of Alcon, who was in town to officially launch Alcon’s Unity Vitreoretinal Cataract System (VCS) and Unity Cataract System (CS), the latest additions to the Alcon Vision Suite.
Mr Leoni told mivision that “the Alcon Vision Suite is terminology we use to describe the ecosystem of products, services, and digital solutions that ultimately, we put into practice to help our customers power their practice”.
He said the suite represents a significant shift in eye care’s approach to technology integration, combining products, services, and digital solutions to help practitioners power their practices while prioritising patient outcomes. This approach creates what he described as a “multiplier effect” – the more Alcon devices that are integrated into a practice, the greater the efficiency and value delivered.
“Customers very much appreciate the Vision Suite because it combines legacy technologies along with innovation, and connects them,” he explained.
Furthermore, this “open ecosystem” is capable of connecting devices from other suppliers “to help surgeons drive their practice in the way that makes sense for them, and at their own pace”.
DIGITAL CONNECTIVITY
The Alcon Vision Suite’s digital connectivity extends beyond the operating room to provide secure data transfer to clinical practices, which not only creates efficiencies, but also improves patient safety.
“Digital really comes down to connectivity in terms of connecting instrumentation within the operating room, but also from the clinic to the operating room,” Mr Leoni explained. “It minimises the risk for things like transcription error, which can ultimately lead to the wrong eye surgery or suboptimal outcomes because of a plan not being transcribed appropriately.”
For surgeons working across multiple facilities, this connectivity offers substantial benefits. “Having the ability to set your parameters on your phaco machine and by the touch of a button, having those parameters uploaded to all your phaco settings under your own personalised login, can be hugely powerful,” Mr Leoni observed.
STAFF TRAINING AND RETENTION
A significant advantage of the integrated ecosystem approach is simplifying staff training in an environment where practices face increasing turnover rates.
“We’ve seen around the world a higher turnover rate of staff members and, of course, staff training is critical,” Mr Leoni said. “The ability for us to facilitate (education) and bring more intuitiveness into the design of the technology (is essential).”
He compared the experience to consumer technology. “Think about in our daily life when the iPad was introduced; for those of us that use the iPhone, it was kind of a seamless experience to transition from the iPhone to the iPad. And that’s the kind of approach that we’re taking with our future technologies.”
UNITY VCS: SETTING NEW BENCHMARKS
The latest addition to Alcon’s Vision Suite – the new Unity VCS – was recently included in the Australian Register of Therapeutic Goods. The system represents a significant advancement, combining cataract and vitreoretinal capabilities in a single console.1
“Unity VCS is our next generation platform for vitreoretinal and cataract surgery.
Australia and Japan were the first markets outside of the US, to have the product available,” Mr Leoni said.
He said the Unity VCS “sets a new benchmark in the surgical experience across both cataract and vitreoretinal surgery”, by creating efficiencies for nurses and staff that enable “faster turnover time and faster calibration ahead of the next case”.2
The technology delivers impressive performance improvements. For cataract procedures, the system can take “half the time with almost half the energy going into theeye”.^3 For vitreoretinal surgery, surgeons are seeing “with 50% faster vitrector cutting speeds”*1,4,5 using 27 gauge technology that feels like 25 gauge technology from a stiffness and control point of view”.**6
DEVELOPMENT PROCESS
Mr Leoni has been involved with the Unity VCS since 2017, when it was “just this features and benefits set on a piece of paper”, and he said its development has involved deep engagement with eye care professionals.
“At Alcon, the way we drive innovation is by seeing the needs of the patients through the eyes of the surgeons that take care of them,” he explained.
He said continuous feedback from surgeons worldwide has resulted in multiple iterations. Even just weeks before launch, Alcon continued to optimise settings and approaches for different surgical techniques.
The Unity ecosystem will continue to expand, with more technologies under the Unity umbrella joining the VCS and CS.
FUTURE DIRECTIONS
Looking ahead, Mr Leoni outlined Alcon's vision focussed on what he calls “the three Es: emmetropia, efficiency, and economics”, each playing a crucial role in delivering better outcomes for surgeons and their practices.
“From an emmetropia point of view, we want to develop technologies that make it easier for customers and staff members to deliver great patient outcomes,” Mr Leoni explained.
He said Alcon’s focus on efficiency addresses the operational challenges practices face today, taking multiple forms, beginning with multi-functional technologies.
For example, with the new Unity VCS he said, “single footprint technology can do cataract and vitreoretinal. That was not the case before”.
Other efficiency drivers include streamlined stafftraining, faster intraoperative procedures “while maintaining a high bar of safety”, and quicker turnover between cases. As Mr Leoni noted, this “enables practices to do one or two more cases in a surgical session, which can be critical in maximising the facility’s uptime”.
Interoperability also plays a key role in efficiency. The ability to “move data from one machine to the next” and enable connectivity for “preventative maintenance and remote service” helps minimise downtime and ensure smoother operations.
The third E (economics) focusses on the business realities facing surgical practices.
“In a world where time is money,” as Mr Leoni puts it, the economic benefits of Alcon’s ecosystem approach are substantial.
Multiple functionalities in a single system reduce capital expenditure and ongoing maintenance costs. The efficiency gains translate directly to revenue opportunities: “The ability to improve efficiency within the individual technologies that we talked about earlier, enable faster procedures. There’s additional revenue that the centres can drive, just by being able to do one or two more cases in a surgical session.”
For practices struggling with staff retention and rising costs, Mr Leonie said these economic benefits can make a significant difference to profitability while still prioritising patient care.

An educational dinner event during the Alcon Focus Symposium provided ophthalmologists with the opportunity to hear all about the evolution of, and early experience with, the Unity VCS and CS surgical platform.
The moderators were Professor Andrew Chang AM and Dr Tanya Trinh (both surgeons at the Sydney Eye Hospital), who engaged the audience while educating surgeons on technologic innovations and reinforcing their significance for patients. Mr Leoni spoke about Australia’s role as the first international market to have Unity VCS available, describing it as “technology that will be with us for years to come and redefine cataract and vitreoretinal surgery around the world”.
Underscoring Alcon’s commitment to innovation, he said the company invests nearly a billion dollars annually in eye care research and development.

PIONEERING FOUR-DIMENSIONAL PHACO TECHNOLOGY
Dr Ivo Ferreira, joining virtually from Mexico in the early hours of his morning, shared his expertise on the Unity VCS system’s groundbreaking fluidics and fourdimensional (4D) phaco technology.1,7 With infectious enthusiasm, he described his journey working alongside the research and development team to test the system in extreme conditions.
“Our Unity came as a revolution,” Dr Ferreira declared, detailing how the system’s intelligent hydraulics outperform existing technologies with sensors positioned closer to the surgical site, enabling faster responses to changes. He said the system’s 4D phaco technology creates a pattern that increases the emulsification area while optimising timing for maximum efficiency.
Dr Ferreira said the system delivers results “two times faster with 41% less energy and 48% less CDE (cumulative dissipated energy)”, and said that once a surgeon experiences Unity, “there’s no wayback”.^3
“The ultimate aim is to empower surgeons to perform more efficient and safer surgery in more patients with complex eye conditions, and to achieve better outcomes”
TRANSFORMING SURGICAL EFFICIENCY AND SAFETY
Associate Professor Smita Agarwal (NSW) – a self-confessed enthusiastic adopter of innovative technologies – presented on the “new kid on the block”, tracing the evolution from Charles Kelman’s introduction of phacoemulsification in 1967 to the current Unity VCS system. She also spoke about the suite’s phaco technology stating that along with improvements in speed, energy usage, and CDE, the phaco handpiece with built-in temperature sensors regulate ultrasonic power to prevent corneal burns.1,3,7
She said the Unity VCS promises improved workflow efficiency with its intuitive graphic user interface, 25% faster system setup, and streamlined inventory management.2

For day surgeries, the combined functionality for both cataract and vitreoretinal procedures means nurses need only learn one system, reducing theatre turnover time significantly.2†,††,‡,§
“Who would not want it?” Assoc Prof Agarwal asked enthusiastically. “I loved it when I tried it.”
UNIFYING ANTERIOR AND POSTERIOR SEGMENT SURGERY
Australian vitreoretinal surgeons were chosen to conduct the first in human trial of the Unity VCS System and new ancillary instrumentation in April 2024. Prof Chang, a trial investigator performing the first surgery in the world with this new technology, highlighted new pump technology, which forms the fundamental basis of efficiency and safety, in both vitreoretinal and cataract surgery. He shared surgical cases and video from the clinical trial demonstrating how technological innovations in fluidics, control of intraocular pressure, including 27 gauge cutter technology, illumination, and instrumentation have addressed the unmet need for vitreoretinal surgeons.
A concluding panel discussion featuring Prof Chang, Dr Trinh, Assoc Prof Agarwal, and Mr Leoni explored the “unification of the anterior and posterior segment” that the Unity VCS platform creates for future development.
Dr Trinh discussed the implications for ‘middle segment surgery’, where collaboration between anterior and posterior segment specialists can improve patient outcomes.
Patients with complex conditions, such as dislocated intraocular lenses combined with anterior segment trauma or disease, require specific instrumentation and specialised skills of corneal, cataract, anterior segment reconstruction, refractive and retinal surgery – and where surgery can be safely combined, is better for the patient. “This is really about patient-driven outcomes and also having a higher standard of safety,” she noted, suggesting Alcon could lead in establishing standards and training for this emerging surgical special interest.
The panel also discussed the system’s physiological intraocular pressure (IOP) settings, with Assoc Prof Agarwal suggesting that “logical IOP is that IOP which is good for that person’s eye,” reminding surgeons of the principle to “do no harm” by reducing IOP where possible.
Mr Leoni shared the commitment of Alcon to continue development of the Unity platform and the panel discussed the importance of surgeon and industry collaboration and partnerships. The ultimate aim is to empower surgeons to perform more efficient and safer surgery in more patients with complex eye conditions, and to achieve better outcomes.
