EP: Balancing Quantity and Quality of Vision at the Rayner 2023 ESCRS Symposium


In this episode, we’re looking back at the 2023 Rayner Symposium at the European Society of Cataract and Refractive Surgeons in Vienna with Professor Graham Barrett, Dr Damien Gatinel, Professor Oliver Findl and Mr Allon Barsam as they discuss Balancing Quantity and Quality of Vision with Advanced Technology IOLs.


Professor Graham Barrett
Professor Graham Barrett is a consultant ophthalmic surgeon at Sir Charles Gairdner Hospital and a Clinical Professor in the University of Western Australia’s Centre for Ophthalmology and Visual Science.  Professor Barrett has made an extensive and varied contribution to ophthalmology, both nationally and internationally. He is founder and immediate past President of the AUSCRS.

Dr Damien Gatinel
Dr Damien Gatinel is among the world’s leading experts in refractive surgery and head of the Department of Refractive and Anterior Segment Surgery at the Rothschild Foundation Hospital in Paris, France. He is the author of more than 170 publications in peer-reviewed journals and also the owner of several patents for IOLs.

Professor Oliver Findl
Professor Oliver Findl chairs the Department of Ophthalmology at the Hanusch Hospital in Vienna, Austria. He has authored over 350 articles in international peer-reviewed journals and is currently the president of the European Society of Cataract and Refractive Surgeons (ESCRS).

Mr Allon Barsam
Mr Allon Barsam is a director and founding partner of OCL Vision, and recognised internationally as an expert and key opinion leader for cataract and refractive surgery.

Key Takeaways:

  • The perfect balance: Professor Graham Barrett explains how he designed the RayOne EMV and, in his opinion, created the perfect balance between range of vision and quality of vision.
  • A fully non-diffractive IOL: Dr Damien Gatinel shed light on Rayner’s optic descriptions for RayOne EMV and RayOne Trifocal and concluded that they have accurately explained their advanced technology optics.
  • Better contrast sensitivity: Professor Oliver Findl shares results from a comparative prospective study with RayOne EMV and AcrySof IQ Vivity noting that there was no significant difference for distance and intermediate vision, nor for reading speed, but that the RayOne EMV had slightly better contrast sensitivity, especially under mesopic conditions with glare, and also smaller halo size.
  • Especially suited for monovision: Professor Findl concludes that RayOne EMV is an enhanced monofocal IOL that is especially suited for a monovision strategy with 0.75 D, or slightly more being optimal to further enhance near vision.
  • Significantly better results: Mr Allon Barsam compared RayOne EMV and AcrySof IQ Vivity in a large cohort study and highlights that while the UIVA was similar for both lenses, the RayOne EMV demonstrated significantly better UDVA and CDVA, as well as a higher patient satisfaction rate with postoperative vision.
