Monovision

Monovision is a popular surgical technique that can expand your range of clear vision compared to some lens options. With monovision, your surgeon will work with you to determine two different IOL powers that work together to provide you with more everyday vision, especially for near activities.

 

  • 97% of monovision patients are satisfied with their visual outcomes1
  • Over 80% report little to no continued use of their glasses2

 

While monovision will often give you excellent vision for distance and intermediate activities, you may still need to wear glasses for some fine print.

Enhanced monovision
with RayOne EMV

Monovision is a trustworthy and proven technique performed on millions of patients around the world each year,3 but when performed with traditional monofocal IOLs rather than RayOne EMV, you could experience reduced visual quality at distance and a smaller range of intermediate vision.

 

Traditional monofocal IOLs may even cause a small gap between the areas with crisp vision (sometimes referred to as the ‘Not Sharply Focused Zone’) in which you may have reduced visual clarity. However, as demonstrated in the illustrative image below, RayOne EMV is designed to solve these problems.4

 

RayOne EMV has a unique optical design that provides uninterrupted vision throughout its focal range, diminishing the Not Sharply Focused Zone (NSFZ).5 It is also designed to offer clearer vision in low-light conditions4 and has the potential to increase your quality of vision for near activities compared to traditional monofocal lenses.5

If you have some astigmatism in your eye, then your surgeon may be able to correct this at the same time with RayOne EMV Toric.

“I have recently had bilateral eye surgery with RayOne EMV Toric, at the age of 46. I am thrilled with my range of vision 3-weeks post-op and am largely spectacle independent, only needing glasses for activities involving small print.”
