About the Study

Published in the Journal of Cataract & Refractive Surgery, the study highlights a clinically relevant application of the SimVis Gekko visual simulator in monovision planning. Conducted across five leading U.S. private practices and including 326 participants, the research evaluated a novel approach to ocular dominance assessment using SimVis Gekko and compared it with the conventional hole-in-the-card test.

Unlike traditional sighting tests, the SimVis-based method assesses dominance under binocular viewing conditions and provides a quantitative measure of both eye laterality and dominance strength, offering a more functionally relevant framework for clinical decision-making.

Key findings

• A 41% discordance between conventional and SimVis-based methods
• Rapid, masked, quantitative assessment in approximately 2.5 minutes
• Functional, binocular sensory measurement aligned with real-world visual experience

Expert perspective

“This award highlights a clinically important point: ocular dominance for monovision should be assessed under binocular viewing conditions, not inferred solely from a sighting test,” said Susana Marcos, PhD. “SimVis enables quantification of both eye laterality and dominance strength in a fast, controlled, and masked manner, bringing assessment closer to real visual experience.”

“For surgeons, the practical relevance of this work is that it moves dominance assessment from a binary classification toward a functional, binocular sensory measurement,” said Jay S. Pepose, MD, PhD. “This creates a more clinically meaningful framework for monovision planning and provides a foundation for studying how dominance strength may relate to adaptation and patient satisfaction.”

Relevance for 2EyesVision

This recognition reflects growing clinical interest in sensory and binocular approaches to ocular dominance assessment. The study, authored by leading surgeons and researchers, aligns with the company’s ongoing efforts to support more informed, sensory-based preoperative assessment and more personalized monovision planning through visual simulation technologies.

About the Obstbaum Award

Presented annually by the Journal of Cataract & Refractive Surgery at the ASCRS Annual Meeting, the Stephen A. Obstbaum Award recognizes the best original research article published in the journal during the preceding year.

The new e-learning platform enables clinicians to become certified in SimVis Gekko and integrate visual simulation into routine IOL counseling

Madrid, Spain, April 2026 – 2EyesVision announces the launch of SimVis Academy, its new e-learning platform designed to support clinicians and partners in the adoption and effective use of SimVis Gekko, the binocular visual simulator for preoperative IOL evaluation.

SimVis Academy provides structured training and certification, enabling users to learn how to integrate real-world visual simulation into preoperative consultations. The platform includes educational modules, scientific content based on published studies, and access to webinars, offering a comprehensive learning environment tailored to clinical practice. The training is designed to be flexible and efficient, allowing users to progress at their own pace and typically completed in approximately one hour. In addition, personalized tutorials can be provided to address specific questions and support individual learning needs. With SimVis Gekko, patients can experience how they would see with different intraocular lenses before surgery, viewing real-world environments rather than simulated images. This approach enhances patient understanding, supports more personalized clinical recommendations, and helps align expectations with postoperative outcomes.

“Training is key to unlocking the full value of visual simulation in clinical practice,” said Marina Martin, Profesional Education at 2EyesVision.

 “SimVis Academy is designed to ensure that clinicians can confidently incorporate this technology into their workflow, improving both patient experience and clinical communication.”

Access to SimVis Academy is available to current customers and partners through 2EyesVision. Distributors can request access for their centers by contacting the company and providing user details. Upon successful completion of the training, participants receive an official certification. The platform is currently available in English and is already accessible to customers worldwide. Additional language versions are under development to further expand accessibility and support global adoption. SimVis Academy represents a new step in 2EyesVision’s mission to make visual simulation a standard part of preoperative cataract and refractive surgery, contributing to more informed, personalized, and patient-centered care.

The Optical Society honors her outstanding contributions to understanding the eye’s optics and its impact on human vision

Rochester, New York, USA – 2EyesVision proudly celebrates the recognition of Prof. Susana Marcos, co-founder of 2EyesVision and internationally renowned vision scientist, as the recipient of the Edgar D. Tillyer Award 2025, presented by Optica (The Optical Society).

This prestigious award honors individuals who have made distinguished contributions to the field of vision — including the optics, physiology, anatomy, or psychology of the visual system. The Tillyer Award was established in 1953 to recognize the legacy of Edgar D. Tillyer and his role in advancing optical science and better vision.

Prof. Marcos receives this recognition “for contributions to our basic understanding of the effect of the eye’s optics on vision, including the passage of light through the cornea and lens and into the photoreceptors where vision begins.”

A leading figure in the field of ophthalmic optics, Prof. Marcos’ research has advanced the understanding of how the human eye forms images and how optical imperfections affect visual performance. Her work has bridged fundamental science and clinical application — from adaptive optics and ocular imaging to the development of SimVis Gekko, the first binocular, see-through simulator that allows patients to experience how they will see after surgery.

“This award not only recognizes Susana’s scientific excellence but also the transformative impact of her work on the future of ophthalmology,” said Carlos Dorronsoro, CEO and co-founder of 2EyesVision. “Her research continues to inspire new ways to connect vision science with patient care.”

The Edgar D. Tillyer Award, endowed by the American Optical Company and the Chope Family Bypass Trust, has been presented annually since 2016 to leaders in vision science who have redefined the understanding of human sight.

At 2EyesVision, Prof. Marcos’ vision and scientific rigor continue to guide the company’s mission: to translate frontier optical research into tools that empower clinicians and improve patients’ lives worldwide.

Leaded by leading researchers, 2EyesVision develops disruptive ophthalmic technologies that help surgeons and patients make more informed, personalized decisions. Discover our work and innovations

Cataract surgery remains one of the most successful medical procedures, yet many patients still experience what is known as the expectation–reality gap: even when visual outcomes are clinically excellent, up to 27% of patients report dissatisfaction because their vision does not meet their expectations.

The article shows how SimVis Gekko is addressing this challenge:

•  Previewing vision before surgery – With SimVis Gekko, patients can experience real-world vision through different intraocular lens (IOL) designs — monofocal, trifocal, and extended depth-of-focus (EDOF) — before making a permanent choice.
• Clinical validation – A study conducted by Dr. Henriques and colleagues at Centro Hospitalar Universitário de Coimbra with 51 patients demonstrated that 92% found SimVis Gekko “very useful” in guiding their lens selection.
• Reducing post-op surprises – By allowing patients to “test drive” IOLs, SimVis Gekko empowers informed decision-making, reduces post-surgery dissatisfaction, and provides surgeons with a valuable tool to align expectations with outcomes.

As Prof. Susana Marcos explained:
“Patients are not only told what to expect but actually see the real world binocularly through the simulated lens and compare across different options.”

This recognition in CAKE Magazine underlines the growing role of simulation technologies like SimVis Gekko in modern cataract surgery and their contribution to more personalized patient care.
