RayOne^® Trifocal

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.

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 their history and possibly the most advanced in the industry.

Improved visual outcomes designed for less pupil dependency.

RayOne^® Trifocal has fewer rings on the optic surface than many trifocal IOLs for reduced potential visual disturbances and improved night vision.

Features

16 diffractive rings / steps
4.5 mm diffractive zone
>4.5 mm monofocal, distance

Benefits

Reduces visual disturbances
Developed to be less dependent on pupil size or lighting conditions
Improves distance vision in mesopic condition

Optimised patented diffractive design

Optimised patented diffractive design is a construct of two profiles to form our patented design:

Graphical representations only of diffractive surface pattern

Exceptional light usage

89% of light transmitted to the retina with a pupil of 3 mm
Half the light allocated for distance
Remaining light divided between near and intermediate vision
Light Energy Split at 3.0 mm pupil
- 52% Distance
- 22% Intermediate
- 26% Near

Comfortable transition from near to distance activities

RayOne® Trifocal improves intermediate visual acuity enabling patients to feel more comfortable transitioning from near to distance activities.

RayOne^® Trifocal is designed with:

+3.50 D near add
37.5 cm reading plane

+1.75 D intermediate add
75.0 cm reading plane

How does RayOne^® Trifocal compare?

RayOne^® 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.

30 healthy test persons IOL simulator study

Designed as a randomised, observer and subject masked, crossover comparison study using an IOL simulator device.

Conclusions:

Visual Acuity of both RayOne^® Trifocal and AT LISA Tri are very similar.
No significant differences between the lenses in far, near and intermediate position could be defined.

Proven haptic technology for excellent stability

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 - Maximum offset of only 1.0 mm 3 months after surgery²
Excellent rotational and torsional stability - 3.1° mean IOL rotation 3 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 IOL optic and are effectively locked into position

Vacuole free material for a glistening free IOL

Single piece IOL created from Rayacryl^® a homogeneous material free of microvacuoles, resulting in a glistening free IOL5
Compressible material for delivery through a small incision
Excellent handling characteristics with controlled unfolding within the capsular bag
Low silicone oil adherence⁶
Excellent uveal biocompatibility⁹
Hydrophilic acrylic material with low inflammatory response⁷

Reducing dysphotopsia by design⁸

Rayner’s Enhanced Square Edge Technology shows no general increase in glare from previous models without a square edge⁴

360° Optimised Barrier to reduce PCO – Low Nd: YAG capsulotomy rates

Rayner's 360° Amon-Apple Enhanced Square Edge creates an optimum barrier to reduce epithelial cell migration including at the haptic-optic junction ^4,3

MEAN TIME TO ND:YAG CAPSULOTOMY⁴		ND:YAG CAPSULOTOMY RATES⁴
At 12 months	0.6%	9.3 ± 5.5 months (range 2.6 - 22.7 months) Follow-up period: 5.3 – 29 months
At 24 months	1.7%

Study of 3,461 patients receiving Rayner 570C IOLs over a 24 month period, Nd:YAG capsulotomy rates were extremely low and comparable with hydrophobic acrylic lenses with square-edge optics⁴
