Developed in collaboration with Professor Graham Barrett, RayOne EMV’s truly non-diffractive optic uses positive spherical aberration to uniquely extend vision.
RayOne EMV’s range of focus can be extended further with a customisable offset for enhanced monovision outcomes.
Unlike many intraocular lenses (IOLs), RayOne EMV does not use light splitting technology. This increases depth of focus, resulting in low levels of dysphotopsia, similar to standard monofocal lenses. RayOne EMV has a unique patented aspheric optic that induces controlled positive spherical aberration. Compared to a lens with zero spherical aberration, the carefully controlled positive spherical aberration induced by RayOne EMV spreads light along the visual axis, elongating the focal range from far into intermediate with up to 1.5D depth of focus (per lens on the spectacle plane).
