The Rayner RayOne EMV (Enhanced MonoVision) is a non-diffractive enhanced monofocal intraocular lens designed to stretch your depth of focus beyond a standard monofocal and to pair perfectly with a blended-vision approach, giving more freedom from glasses after cataract surgery or refractive lens exchange. UK 2026 guide cost is from around £3,200 per eye, all-inclusive of surgery, the lens and aftercare.
What the RayOne EMV is
Designed and made by Rayner in the UK, the RayOne EMV has a specially shaped, aberration-controlled optic that extends the range of clear focus without splitting light the way a diffractive multifocal does. That means good distance vision and useful intermediate vision — ideal for screens, dashboards and everyday tasks — while keeping night vision clean, with far fewer of the haloes and glare some patients notice with trifocal lenses.
It is most powerful in a blended-vision (mini-monovision) plan: the dominant eye is set for distance and the second eye is set very slightly for near, and the brain merges the two into a continuous range. It is implanted during the same gentle cataract surgery or refractive lens exchange procedure as any other lens.
Who it suits
The RayOne EMV suits people who want more spectacle freedom than a standard monofocal but who value crisp night vision and drive a lot or use screens, and who would prefer to avoid the night-time haloes that diffractive trifocals can cause. Your surgeon confirms whether a blended-vision target is right for your eyes, your prescription and the way you use your vision. If you want the maximum possible freedom from reading glasses, your surgeon will also discuss trifocal and EDOF options and the trade-offs of each.

Frequently asked questions
How much does a RayOne EMV lens cost in the UK?
As a UK 2026 guide, RayOne EMV lens surgery is from around GBP 3,200 per eye, all-inclusive of surgery, the lens and aftercare. A toric version for astigmatism is available at a small premium. Your exact quote is confirmed after a biometry assessment.
What is an enhanced monovision (EMV) lens?
It is a non-diffractive enhanced monofocal that extends the range of clear vision beyond a standard monofocal, designed to work in a blended mini-monovision plan: distance in the dominant eye and slightly near in the other, merged by the brain into a continuous range.
Will I still need glasses with the RayOne EMV?
In a blended-vision setup most patients are far less dependent on glasses for distance and intermediate tasks, though fine print or prolonged reading may still need glasses. It gives cleaner night vision than diffractive trifocals, at the cost of a little less near vision.
RayOne EMV or a trifocal lens?
The RayOne EMV prioritises clean, glare-free vision with a good everyday range; a trifocal maximises freedom from reading glasses but can cause more night-time haloes. The right choice depends on your eyes and how you use your vision, which your surgeon assesses.
