EP: Getting Started with RayOne EMV


Dr Michael Endl (US) reflects on his extensive experience with RayOne EMV. Having successfully implanted RayOne EMV in nearly 100 eyes, Dr Endl notes that the lens has granted patients a wide range of independence from wearing spectacles, encompassing near, intermediate, and distance vision.

Dr Michael Endl is a partner at Fichte, Endl & Elmer Eyecare. He is also head of ophthalmology at Ambulatory Surgery Center of Western New York in Niagara Falls, NY and is the Medical Director of the Ambulatory Surgery Center of Western New York in Amherst. He is an FDA clinical trial investigator and has presented peer-reviewed papers at the American Academy of Ophthalmology and the American Society of Cataract and Refractive Surgeons (ASCRS) annually since 2001. Dr Endl has also written numerous chapters in books and peer-reviewed medical journals. He has performed over 40,000 refractive surgery procedures, and over the past ten years has expanded his corneal practice to include micro-invasive glaucoma procedures and advanced corneal grafting.

Key Takeaways:

  • 100 eyes: Dr Endl has implanted RayOne EMV in nearly 100 eyes since learning about the IOL that was developed with Professor Graham Barrett.
  • Patient expectations: Dr Endl believes that in modern society, patients are increasingly demanding a better range of vision, but without compromise.
  • Broader range of spectacle independence: Dr Endl recommends using RayOne EMV by targeting the dominant eye first for optimal distance vision, before operating on the second eye two weeks later. The period in-between bilateral implantation allows patients to provide feedback on their vision, which allows surgeons to determine the appropriate correction for the second eye, to achieve the desired visual outcome. If the patient needs some range inside of 20 inches, Dr Endl targets the non-dominant eye with -0.75 to -1.0 D.
  • Surgeons new to RayOne EMV: Dr Endl recommends using RayOne EMV at plano for the dominant eye, and a small minus for the non-dominant eye.
  • Contrast sensitivity: Dr Endl refers to a real-world patient satisfaction survey submitted to the ASCRS, with 30 patients implanted with RayOne EMV compared to 30 patients with a standard monofocal lens – the results showed no difference in reported contrast sensitivity.
  • Patient satisfaction: Dr Endl explains that patient satisfaction with RayOne EMV for intermediate and near activities, when compared with a standard monofocal lens, is almost double. Dr Endl’s patient satisfaction survey also showed no increase in visual noise or difficulty with nighttime driving.
  • Counselling patients: Dr Endl offers three package options for his patients, including tier 1: monovision, tier 2: enhanced monovision (where RayOne EMV is his lens of choice) and tier 3: Trifocal IOL.
