Patient expectations from lens surgery are changing, with an increasing desire to be spectacle free as they continue to lead highly active and social lifestyles until much later in life.
Whether your patients are having cataract surgery or visiting you for refractive enhancement, our complete family of trifocal IOLs are clinically proven to provide them with the best visual outcomes.
As a surgeon, you always want to provide your patients with the best possible visual outcomes. However, patients that desire spectacle independence are not always suitable candidates for diffractive trifocal IOLs. To overcome these challenges, many surgeons turn to monovision as an affordable way of delivering some extended depth of vision with reduced dysphotopsia.
RayOne EMV was developed in collaboration with world renowned surgeon, Professor Graham Barrett, to specifically enhance patient outcomes achieved with monovision.
RayOne EMV uniquely extends a patient’s range of vision with a patented non-diffractive optic profile, enabling the depth of field of many presbyopia-correcting IOLs but with reduced dysphotopsia, short neuroadaptation, reliable outcomes, high patient satisfaction, and improved affordability.
Offered on a superior hydrophilic optic platform through the RayOne fully preloaded two-step injector, RayOne EMV is an IOL solution unlike any other.

RayOne EMV provides a smoother, blended transition between the dominant and non-dominant eyes when compared to monovision achieved with standard monofocals, maintaining binocular stereoacuity and reducing asthenopia.
The patented optic provides high quality spectacle-free distance vision as well as reduced pupil dependency for optimised performance under low light conditions.
FEATURES & BENEFITS
The Modulation Transfer Function (MTF) graph below shows the binocular optical performance for RayOne EMV and a competitor’s negatively aberrated aspheric IOL, targeted for a monovision offset of +1.0 D.
• Good performance at distance
• 2.25 D extended depth of vision with +1.0 D offset
• Greater imaging capability in the non-dominant eye than the competitor lens, providing binocular distance vision and a smooth, blended transition zone between lenses
• Due to the extended depth of vision, the dominant eye will also be more forgiving of post-operative myopic shift when compared to aberration negative aspheric IOLs.
• Increased range of functional vision
• Minimal dysphotopsia
• High patient satisfaction
RayOne EMV is designed with an aspheric anterior surface and unique inner optic zone which induces controlled positive spherical aberration to extend depth of field without compromising visual acuity under low-light conditions.
RayOne EMV provides up to 2.25 D of extended depth of vision with a 1.0 D offset, improving intermediate vision compared to monovision achieved with standard monofocals and reducing dysphotopsia compared to diffractive IOL designs.
