High quality natural vision

Developed in collaboration with world renowned surgeon, Professor Graham Barrett, RayOne EMV is a highly versatile lens that meets the visual needs of a large population of cataract and refractive patients3 looking for greater spectacle independence than offered by standard monofocal lenses.

  • Increased range of focus: >1.5 D1,4,6 with an emmetropic target.
  • High quality natural vision: Truly non-diffractive IOL with monofocal levels of contrast sensitivity1, dysphotopsia2 and high levels of patient satisfaction.3
  • Optimised for monovision: Positive spherical aberration design and the resulting hyperopic tail provides a more natural range of vision with a smoother transition between distance and near eyes.2,4
  • Easy to integrate: A similar surgeon experience to your monofocal IOLs,5 and now available on the RayOne Toric Platform.

 

 

“For many years I have worked on optimising a lens for monovision, given that it accounts for nearly 30% of all surgeries. I collaborated with Rayner on bringing this lens to market as RayOne EMV, an exciting new product for all surgeons looking to treat presbyopia reliably”

How does RayOne EMV work?

RayOne EMV is a truly non-diffractive IOL which does not use light splitting technology like many IOLs which increase depth of focus, resulting in low levels of dysphotopsia, similar to standard monofocal lenses.1

RayOne EMV is the only patented aspheric IOL 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 over 1.5 D of depth of focus (per lens on the spectacle plane). 

Below shows an illustration of a lens with zero aberration and a small focal range (Figure 1), shown together with RayOne EMV with positive spherical aberration and a larger focal range (Figure 2).

 

Why is positive spherical aberration good for extending depth of focus?4

The positive spherical aberration induced by RayOne EMV complements the natural spherical aberration of the human cornea and gently increases depth of focus into the intermediate range – see illustrative Figure 3.

An equivalent negative spherical aberration IOL needs to first negate the positive spherical aberration of the cornea, then add even more negative spherical aberration to induce any required depth of focus improvements.

The total spherical aberration used on the RayOne EMV is therefore designed to be significantly less than for equivalent negative spherical aberration extended depth IOLs, and the RayOne EMV optical surface remains closer to spherical in form, thus making performance more consistent under normal tilt and decentration conditions.

KEY INFORMATION

  • >1.5 D increased range of focus with an emmetropic target.1,4,6
  • Low levels of contrast sensitivity1 and dysphotopsia2, similar to standard monofocal lenses.
  • Positive spherical aberration design provides a natural range of vision.2,4

DESIGNED TO PROVIDE

  • Smoother, blended transition between the eyes when compared to monovision with standard monofocals, maintaining binocular stereoacuity and reducing asthenopia. 
  • High quality spectacle-free distance vision.
  • Reduced pupil dependency, for optimised performance under low light conditions.
  • Reduced sensitivity to decentration and tilt compared to other IOL designs. 
  • Complements the eye’s natural level of spherical aberration.
  • Fully preloaded across the entire power range.

Clinical results with RayOne EMV

Since the launch of RayOne EMV in 2020, clinical data from across Europe has demonstrated that:1,2,3,6,7

  • RayOne EMV can provide spectacle independence in the distance to intermediate vision.
  • RayOne EMV provides improvement in intermediate vision without compromising the binocular distance vision.
  • RayOne EMV can help to improve your patients near vision.

 

The following clinical results are from patients in the UK, Spain and Portugal during the months leading up to the commercial launch of RayOne EMV.2

 

 

“RayOne EMV can easily be the lens that helps surgeons go from being a standard lens surgeon to a premium lens surgeon. It is a natural, easy transition for most surgeons to make, and it provides patients with good quality distance and intermediate vision along with useful near vision for many, particularly
with a mini-monovision approach.”

Mr Allon Barsam, Consultant Ophthalmic Surgeon & Director at OCL Vision
