Correct more of your patients — even those with significant, corneal astigmatism
Exceptional rotational stability, ensuring effective visual performance and reliable astigmatism correction.
RayOne EMV Toric delivers immediate and reliable astigmatism correction — in a robust FDA IDE trial:¹
Patients implanted with RayOne EMV Toric had a clinically significant reduction in residual cylinder, surpassing the FDA’s recommendation of 0.4 D.
RayOne EMV Toric provided consistently precise astigmatism correction with >85% of patients within ±0.5 D from Month 1 onwards.

Clinical results with RayOne EMV
RayOne can provide spectacle independence for distance and intermediate vision.¹⁵
RayOne EMV provides improvement in intermediate vision without compromising binocular distance vision.¹²˒¹⁵˒¹⁶
Contrast sensitivity levels similar to standard monofocals in both photopic and mesopic conditions.¹⁰
Since the launch of RayOne EMV in 2020, real world clinical data has demonstrated that:
The following clinical results are from a prospective, single-center, observational, noncomparative study conducted at San Carlos Hospital, Madrid, Spain. The study aimed to evaluate visual and refractive outcomes, as well as patient satisfaction, following bilateral implantation of RayOne EMV (IOL) in 50 eyes, with emmetropia as the target refraction.¹⁶
Outcomes reveal excellent binocular CDVA and good DCIVA, with a high level of patient satisfaction.¹⁶

Comparative outcomes with RayOne EMV
At the Hospital da Luz Lisboa in Lisbon, Professor Filomena Ribeiro and Professor Tiago Ferreira led a 150 patient double-arm, non-randomised prospective case series where RayOne EMV demonstrated excellent visual outcomes for distance and intermediate vision, and good visual acuity for near vision.¹⁰
No statistical difference in contrast sensitivity from a standard monofocal and slightly better contrast sensitivity levels than extended depth of vision (EDOF) IOLs under photopic conditions.¹¹
Patients in the RayOne EMV group experienced a high level of spectacle independence and a photic phenomena profile similar to standard monofocals.¹¹
“RayOne EMV is a solution that gives patients increased satisfaction with the least compromise in their quality of vision.
I am pleased that US surgeons will now have access to the full EMV family of lenses, including a rotationally stable toric option for patients with astigmatism.”

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.²
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.
