Long-standing, UK-based intraocular lens (IOL) designer and manufacturer Rayner has unveiled its latest monovision IOL evolution, the RayOne EMV, designed in collaboration with Professor Graham Barrett, president of the Australasian Society of Cataract & Refractive Surgeons.
The RayOne EMV is a fully preloaded, non-diffractive IOL designed to uniquely extend a patient’s range of vision with a patented, non-diffractive aspheric optic profile providing up to 2.25D of extended depth of vision (with 1.0D offset) and superior intermediate vision, said Rayner CEO, Tim Clover. “RayOne EMV was created specifically for surgeons who currently utilise standard monofocal IOLs to achieve monovision but would like to see better intermediate visual outcomes without increasing the frequency of challenges experienced with other premium IOLs such as dysphotopsia and patient affordability.”
Rayner’s new lens is the world’s first IOL designed specifically for monovision treatment, said Christian Oster, group marketing manager for Australasian distributor Designs for Vision (DFV). “RayOne EMV gives patients extra depth of focus that they wouldn’t experience with monofocals (and) offers a smoother transition between the dominant and non-dominant eye, reducing any asthenopia caused by the dioptre power offset.”
Following European CE mark approval earlier in 2020, Rayner conducted a multi-surgeon, multi-site evaluation of its new IOL in Portugal, Spain and the UK. Surgeons performing first-in-eye implantations reported high levels of satisfaction with RayOne EMV performance, reported the company. “Visual acuity data indicated favourable results at both distance and intermediate at one month. Uncorrected bilateral distance visual acuity was reported as -0.08 ± 0.09 and intermediate -0.05 ± 0.17. Patients implanted with RayOne EMV were highly satisfied with their postoperative refractive outcomes and were completely dysphotopsia-free.”
Rayner’s new IOL should be available from DFV from November this year.
