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.
