RayOne® Toric

RayOne® Toric

Proven rotational stability2 and excellent centration for predictable, sustainable and accurate visual results, make the RayOne® Toric IOL the ideal choice for treating cataract patients with pre-existing corneal astigmatism.

Anti-vaulting haptic (AVH) technology offers excellent fixation within the capsular bag, and an extensive range of sphere and cylinder power combinations allow more patients to be accurately corrected, even those with high levels of corneal astigmatism.

All of this on our primary RayOne® platform with patented Lock & Roll™ technology for the smallest fully preloaded IOL incision.

 

Designed with AVH Technology® for excellent fixation within the capsular bag:1

  • Progressively taking up the forces generated within the contracting capsular bag
  • Maintaining excellent centration with rotational, torsional and directional stability

In a prospective study of 27 eyes in 22 consecutive patients with >1.5 D regular corneal astigmatism, at 3 months post-operatively, variations from intended axis were:2

3.1°
mean variation
93% of IOLs
were ≤ 10°
100%
were ≤ 12°
Percentage cylinder reduction of
81%
(-2.70 ±0.94 to -0.52 ±0.63 D)

Stability achieved through advanced haptic design

 
Outer haptics begin to take up the compressions 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
  • The low refractive index (1.46) of Rayacryl®

Reducing dysphotopsia by design8

 
  • Rayner’s Enhanced Square Edge Technology shows no general increase in glare from previous models without a square edge4
  • The low refractive index (1.46) of Rayacryl®

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 optics7
