A leading Swiss clinic embracing modern glaucoma care
Located in the heart of Geneva, Genève Ophtalmologie is a modern, state-of-the-art private eye care center that has quickly established itself as a reference since opening in 2023. The clinic is designed around a patient-centered model and brings together a highly specialized team of ophthalmologists, orthoptists, and diagnostic technicians to provide comprehensive, cutting-edge care. Its areas of expertise include glaucoma and pediatric ophthalmology. The clinic is led by Dr. Kevin Gillmann, Medical Director and an internationally recognized expert in glaucoma.
With more than 50 peer‑reviewed publications, book chapters, and editorial work on glaucoma guidelines, Dr. Kevin Gillmann has trained and practiced at world‑renowned institutions including Moorfields Eye Hospital in London, Kingston University, Harvard Medical School, and the Swiss Glaucoma Research Foundation. He was ranked among the top 0.5 % of glaucoma specialists worldwide by Expertscape, reflecting his international recognition and expertise in the field. His clinical practice places strong emphasis on precision diagnostics, longitudinal monitoring, patient quality of life, and evidence‑based decision‑making.
Genève Ophtalmologie’s team also relies on the expertise of their head orthoptist, Athena Lallouette, who manages the majority of the clinic’s functional assessments and plays a key role in ensuring a smooth diagnostic workflow.
Like many modern ophthalmology practices, the clinic faced growing pressure to perform visual field tests that were faster, more comfortable, and easier to integrate into daily patient flow. Traditional bowl perimeters often required dedicated dark rooms, significant technician time, and lengthy preparation for each exam. The devices were bulky, uncomfortable for elderly patients, and frequently led to unreliable or incomplete tests due to fatigue or difficulty maintaining fixation.
In a busy private clinic managing high volumes of glaucoma and at-risk patients, these constraints were increasingly at odds with the need for efficient, patient-friendly, and scalable diagnostics.
Challenge: The limitations of traditional visual field testing
Before VisionOne™, Genève Ophtalmologie relied on traditional bulky bowl perimeters that required dark rooms, eye patching, and long technician-supervised sessions. Many elderly patients found repeated room changes tiring, leading delays and clinic flow disruption, as head orthoptist Athena Lallouette highlighted. With rising patient volumes, the clinic needed a faster, more flexible, patient-friendly solution that reduced burden for staff and patients without compromising diagnostic quality.
Implementing VisionOne™ at Genève Ophtalmologie
Dr. Kevin Gillmann first encountered VisionOne™ almost four years ago, during the earliest stages of its development. At the time, he approached the technology with healthy skepticism, unsure whether a VR-based perimeter could match the clinical reliability of traditional devices. After receiving a prototype for preliminary evaluation, he personally tried and tested it, first on himself, then among his staff, and finally with patients as part of a small-scale clinical study, before considering broader adoption.
These first hands-on trials quickly shifted his perspective. VisionOne™ eliminated several long-standing barriers in visual field testing: no dark room, no eye patch, and no need to maintain a rigid head position. Importantly, beyond the form factor, VisionOne™ is not simply a VR headset replicating conventional perimetry: its AI-driven SORS testing strategy is designed to dramatically shorten test time while maintaining (and in published evaluations, improving) test consistency compared with gold standard algorithms. The guided test flow allowed patients to follow the procedure intuitively, reducing stress and improving cooperation.
Patient acceptance rapidly became one of the strongest arguments for integration into the clinic. According to Athena and Dr. Gillmann’s peer-reviewed study, 96% of patients rated their experience as good or very good. In routine clinical use, the clinic has also observed similarly high acceptance among very elderly glaucoma patients, including individuals in their nineties, who adapted to the headset with surprising ease. Technicians also welcomed the transition, appreciating the reduced setup time and the smoother workflow compared with conventional perimeters.
As a result, VisionOne™ became a natural fit for Genève Ophtalmologie’s glaucoma practice, offering both the clinical rigor required by specialists and the comfort and efficiency needed for today’s patient volumes.
Clinical validation: Proven accuracy in real-world use
VisionOne™ has undergone extensive validation across leading clinical centers, confirming its equivalence to conventional perimetry while offering faster and more consistent testing.
At Bern University Hospital, VisionOne™ showed a 0.91 correlation with the Octopus perimeter, demonstrating strong agreement with a gold-standard device. Inter-specialist comparison revealed that clinicians agreed more closely on VisionOne™ results than on traditional visual fields, reinforcing its reliability in real-world interpretation.
Further evaluations with NHS Lothian and the University Hospital Bern using the SORS testing strategy confirmed the performance benefits already seen in glaucoma clinics (see research):
• 60–70% faster than SITA Standard
• Markedly lower variability (0.09 dB test–retest vs 1.0–2.0 dB)
• Equivalent clinical decisions compared with Octopus fields
As Dr. Gillmann notes: “Visual field algorithms have traditionally involved a trade-off: speed versus reliability. With VisionOne’s SORS, it’s the first time I’ve seen both - without compromise.”
These results demonstrate that VisionOne™ provides clinically actionable data and is suitable not only for routine practice but also for remote or at-home monitoring settings.

Workflow impact: Transforming efficiency for doctors, technicians, and patients
Since adopting VisionOne™, Genève Ophtalmologie has experienced a profound shift in how visual field testing fits into daily clinical operations. What used to be a slow, room-dependent, and staff-intensive process has become one of the clinic’s most streamlined workflows.
With traditional perimeters, a single visual field exam required 20 to 25 minutes, including preparing the device, escorting the patient to the dark room, patching one eye, adjusting positioning, and supervising the test. Today, VisionOne™ allows head orthoptist Athena Lallouette to manage the full process in about 10 minutes, from seating the patient to reviewing the cloud-synced results. This efficiency gain alone has dramatically improved patient flow, freeing clinicians and technicians for other tasks.
The removal of the dark-room bottleneck has had one of the biggest impacts. VisionOne™ can be used anywhere in the clinic, which immediately increased throughput by around 40%. Instead of waiting for the dark room to become available, tests can now be performed directly in examination rooms, imaging rooms, or even communal diagnostic spaces. This flexibility has also improved scheduling, allowing staff to adapt quickly to urgent visits or unexpected delays. In practical terms, many patients can now complete their glaucoma testing within a standard 30-minute appointment, rather than returning for a second visit or requiring extended slots.
The benefit is especially clear for elderly glaucoma patients, who often struggle with repeated transitions between rooms. Athena notes that before VisionOne™, many frail patients had to be helped out of their chairs, guided down the hall, and repositioned multiple times just to complete a single visual field test.
With VisionOne™, “patients can stay exactly where they are — even the very elderly — and the entire test happens from the same chair.” This reduces fatigue, improves cooperation, and makes the overall visit easier for both the patient and the clinician.
For technicians, the system has brought meaningful relief from repetitive manual tasks. There is no longer a need to adjust chin rests, position fixation targets, or continuously supervise the test. There are no eye patches to apply or remove, no rooms to darken, and no touchscreen calibration to perform. Instead, VisionOne™ offers a guided test flow that allows Athena and her colleagues to focus on patient interaction rather than mechanical setup.
Once the test is complete, results are immediately uploaded to the secure cloud, giving Dr. Gillmann access to the visual field in seconds, a considerable improvement over the slower, often manual export processes of legacy systems. VisionOne™ can also operate offline, allowing the team to maintain full testing capabilities even during network interruptions or external deployments.
Finally, the portability of the headset opens possibilities beyond the clinic. Genève Ophtalmologie sees VisionOne™ as a practical tool for hospital visits, satellite offices, or humanitarian missions, where reliable, quick, and accurate perimetry is needed but traditional equipment is impractical.
Overall, VisionOne™ has become a catalyst for a more efficient, patient-friendly, and flexible workflow, one that supports the realities of modern glaucoma care while reducing the operational burden on staff.
Patient experience: Comfort, acceptance, and loyalty
One of the most striking impacts of VisionOne™ at Genève Ophtalmologie has been the transformation of the patient experience. Feedback collected in routine use shows that over 96 percent of patients rate the experience as good or very good, a level of acceptance rarely seen in visual field testing.
Patients who previously struggled with the discomfort of traditional perimetry, the chin rest, the eye patch, the dark room, and the long periods of fixation, now feel noticeably more at ease. The VR format reduces anxiety and physical strain, which in turn lowers the risk of fatigue, loss of fixation, or test abandonment.
Many patients describe the exam as “far less stressful” and “surprisingly comfortable.”
This comfort directly affects clinical behavior. Patients are increasingly willing to test more frequently, allowing for closer monitoring without resistance or frustration. The difference is particularly clear among older adults with glaucoma. Even patients in their eighties and beyond adapt quickly to the guided VR workflow, following instructions naturally and completing the exams without difficulty.
The improved experience has had a visible effect on patient loyalty and clinic reputation. Several individuals have shared with the staff that they chose to continue their care, or even switched to Genève Ophtalmologie, because they heard the clinic uses VisionOne™. The combination of comfort, modern technology, and efficiency reinforces a sense of trust and reinforces long-term patient engagement.
By making visual field testing easier, calmer, and more accessible, VisionOne™ improves not only diagnostic quality but also the overall patient journey, a meaningful advantage in glaucoma care, where repeated testing is essential.
Results: A transformed glaucoma care model
Since adopting VisionOne™, Genève Ophtalmologie has undergone a profound shift in how glaucoma diagnostics are delivered. Dr. Kevin Gillmann has largely replaced his Humphrey perimeter with VisionOne™, making it the clinic’s primary visual field testing platform for both routine and complex glaucoma cases.
The impact on clinic operations has been clear and immediate in day-to-day use. The diagnostic pathway is now faster, allowing many patients to complete their glaucoma assessment within a single visit. Without adding staff or rooms, the clinic estimates it increased functional testing capacity by ~40%, while also improving patient comfort and satisfaction. This throughput gain is driven by a simpler workflow: technicians spend less time moving patients between rooms and setting up complex equipment, and results are available instantly via the cloud. In practice, the clinic has observed meaningful efficiency gains for technicians and shorter waiting times for patients.
Test reliability has also improved. The guided VR workflow reduces fatigue and fixation losses, leading to more consistent and usable visual fields. These improvements contribute to clearer clinical decisions and more effective long-term monitoring.
From the patient perspective, VisionOne™ has become a welcomed part of the exam. Satisfaction scores remain consistently high, and several patients have commented on how much more pleasant and less stressful the VR test feels compared to traditional perimeters.
Reflecting on the change, Dr. Gillmann explains: “Many patients used to dread visual fields, and it showed in the results. Now testing is quicker and calmer, the fields are more consistent, and the conversation can shift from ‘getting through the test’ to interpreting something meaningful.”
VisionOne™ has enabled a more efficient, patient-friendly approach to glaucoma monitoring, integrating more smoothly into real-world clinic workflows while improving the usability of results for clinical decision-making.
A practical model for modern glaucoma care
Genève Ophtalmologie illustrates how glaucoma care can evolve when visual field testing becomes faster, more intuitive, and truly patient-friendly. By integrating VisionOne™ into daily workflows, the clinic has shown that a portable, guided VR platform with AI-driven algorithms can support clinical decision-making comparable to conventional perimetry, while significantly reducing operational friction and improving patient acceptance.
By pairing a guided VR experience with an AI-driven testing strategy, VisionOne™ brings together speed, reliability, comfort, and real-world usability, without forcing the traditional trade-off between them.This makes VisionOne™ a strong candidate for a new standard in glaucoma functional testing.
Genève Ophtalmologie’s experience demonstrates that meaningful progress in eye care will come not only from incremental device upgrades, but from redesigning how testing is delivered: smarter, more accessible, more workflow-friendly, and better aligned with the needs of today's patients and clinical teams.
