PROBLEM & UNMET NEED
Presbyopia is a non-preventable, gradual, and irreversible eye condition characterized by the loss of the ability to focus on near objects. It causes significant visual symptoms in over 80% of the population above the age of 50—more than 2 billion people by 2024. Similarly, cataracts are age-related opacifications of the eye’s natural lens. As of 2025, they affect
over 50% of individuals over 75 years old—approximately 110 million people. Cataract surgery is among the most frequently performed procedures worldwide, with around 30 million surgeries conducted annually (second only to childbirth).
Surgery is the standard treatment for both conditions. It involves replacing the eye’s crystalline lens with an artificial intraocular lens (IOL). There are over 100 different IOL models available from more than 30 manufacturers, each offering a distinct visual experience. However, the effect of each lens is difficult to convey, and patients cannot preview their
postoperative vision. As a result, lens selection is typically made through a simple conversation between doctor and patient, without incorporating the patient’s feedback or preferences.
This suboptimal selection process leads to reduced postoperative satisfaction and poses a significant barrier to the adoption of multifocal lens corrections.
OUR TECHNOLOGY & SOLUTION
SimVis technology is based on temporal multiplexing using tunable lenses (TLs), which change optical power in response to electric signals. 2EyesVision’s proprietary technology allows presbyopic and cataract patients to experience the real world through simulations of existing intraocular lenses—enabling them to “try on” different visual corrections prior to
surgery and provide feedback that informs the selection of the most appropriate IOL.
Our product, SimVis Gekko2, is a visual simulator for presbyopia and cataract surgery that, for the first time, enables patients to test multifocal corrections before implantation. It is a binocular, head-mounted, see-through optical device that provides a natural visual experience.
