New research from a CooperVision and University of Rochester Flaum Eye Institute team, in collaboration with the Instituto de Optica “Daza de Valdés” (IO-CSIC), has identified a novel marker for presbyopic accommodation that may drive future category innovation. The paper was presented at the ARVO 2025 Annual Meeting in Salt Lake City, Utah, on Wednesday, May 7.
ABOUT THE RESEARCH
OCT-Based Marker for Accommodative Effort in Presbyopes1 explores how both anterior segment and crystalline lens geometry change in relation to accommodative demand, specifically among emmetropic and myopic presbyopes with different correction needs. Using 3D optical coherence tomography (OCT), the investigators observed measurable geometric alterations across the range of subjects and presbyopia stages. Some focus ability, even though diminished, remained in presbyopes. Crystalline lens thickness emerged as a key marker for assessing focusing effort in such individuals, particularly in myopes.
“We believe this is the first in vivo study to show the evolution of physiological response of the crystalline lens as adults age,” said Percy Lazon de la Jara, Director of Research Programs for CooperVision and a paper co-author. “CooperVision’s deep commitment to advancing ocular science and care means evaluating the entire eye, including how it changes from presbyopia onset through stabilization. This latest work—employing a remarkable application of OCT to uncover previously unavailable insights—will help map optical corrections that could be incorporated into future presbyopia correction methods and devices.”
Presbyopes today make up about one-third of the world’s population, affecting those in their mid-40s.2 CooperVision manufactures a range of contact lenses for correcting the condition, including MyDay® multifocal and clariti® 1 day multifocal 3 Add.* Both feature the CooperVision Binocular Progressive System®, an innovation that caters to all levels of presbyopia to provide optimal visual acuity at all distances.3,4 The innovative technology system offers the additional advantage of a simple fitting process3 to make it easy for eye care professionals to fit patients with the right lens.
CooperVision scientists and research partners will also share additional foundational and clinical research during ARVO 2025, which is attended by thousands of ocular scientists, clinicians, educators, and students. Among several posters are topics relating to myopia management (e.g., Myopia Control Efficacy and Choroid Response with Dual-Focus Contact Lenses in Chinese Children)5 and contact lens comfort (e.g., Characterizing Sensory Adaptation in Contact Lens Wearers Experiencing Ocular Discomfort).6
