Dr. Robert Weinstock is the First Cataract Surgeon in the USA to Implant the Rayner RayOne IOL

Dr. Robert Weinstock Implants Rayner RayOne IOLDr. Robert Weinstock, Director of Cataract and Refractive Surgery at The Eye Institute of West Florida, became the first surgeon in the USA to implant Rayner’s RayOne IOL.

FDA-approved cataract lens, RayOne EMV, was developed to provide clear, crisp vision at distance and intermediate ranges of vision.

Dr. Mariano Royo, Director of Ophthalmology at the Hospital San Rafael in Madrid and Director of the Ophthalmic Institute of Madrid, shared his clinical results of 22 eyes of 11 patients implanted with RayOne EMV measured at 6 months post-op. Dr. Royo reported that 100% of his patients that received RayOne EMV achieved spectacle independence in the distance and intermediate range. The average reading aid at 33 cm was reported to be +1.5 D, and one in three patients had functional near vision without the need for spectacles.1

RayOne EMV is a cost-effective solution for patients when other IOLs may be cost prohibitive.

“Following approval of our RayOne and RayPRO platforms in 2019 we have been steadily increasing our investment in the USA to be one of our most important markets worldwide,” Tim Clover, Rayner CEO, said in a company news release. “The approval of RayOne EMV is important as it allows surgeons to offer patients a new option which has been tried and tested in thousands of patients around the world”

Being at the forefront of innovative technology has allowed our The Eye Institute of West Florida to deliver above average visual outcomes to patients undergoing cataract surgery. With many IOLs (intra-ocular lenses) to choose from, The Eye Institute of West Florida ensures you will meet your visual goals based on your particular lifestyle needs.
