RayOne Trifocal has a new patented diffractive profile that has been designed in partnership with a leading European technology institute. Over the last four years Rayner has developed the most advanced optic in our history and possibly the most advanced in the industry.
RayOne Trifocal is the newest member of the RayOne family of preloaded IOLs, based on the well-known high performance Rayner platform that performs again and again.
Any rotation, tilt or decentration of a multifocal lens could affect patient outcomes and cause phototopic disturbances. Our anti-vaulting haptic technology gives proven rotational and centrational stability, plus excellent fixation in the capsular bag1:
• Superb centration – Average offset of only 0.08 mm 3 to 6 months after surgery2
• Excellent rotational and torsional stability – 1.83° mean IOL rotation 3 to 6 months after surgery2
Outer haptics begin to take up the compression forces of post-operative capsule contraction
Outer haptics engage the inner haptics
Haptic tips gently meet the optic corners and are effectively locked into position
RayOne Trifocal has a new patented diffractive profile that has been designed in partnership with a leading European technology institute. Over the last four years Rayner has developed the most advanced optic in our history and possibly the most advanced in the industry.
The diffractive profile is a construct of two profiles to form our patented design:
Graphical representations only of diffractive surface pattern.
RayOne Trifocal has fewer rings on the optic surface than many trifocal IOLs for reduced potential visual disturbances and improved night vision.
Features
Patient benefits
Our patented diffractive step trifocal technology reduces light loss to only 11%
RayOne Trifocal Toric improves intermediate visual acuity enabling patients to feel more comfortable transitioning from near to distance activities.
RayOne Trifocal Toric is designed with:
| +3.50 D near add 37.5 cm reading plane | +1.75 D intermediate add 75.0 cm reading plane |
RayOne Trifocal offers excellent performance across Near, Intermediate and Distance vision, and with the retained light energy through the diffractive profile providing excellent contrast sensitivity. In low light conditions when compared to other diffractive trifocal technologies the RayOne Trifocal maintains its performance across the three foci points.
