How many of your cataract patients would benefit from a T-flex Aspheric Toric IOL?
Prevalence of pre-operative corneal astigmatism in a cross-sectional study of 746 patients (1230 eyes):13
- Over 40% presented with >1.0 D of astigmatism
- More than 20% presented with >1.5 D of astigmatism
Why leave your post-operative patients with residual astigmatism?
Vision with cataract and astigmatism
Post-operative - conventional IOL
Post-operative - T-flex Aspheric IOL
Proven rotational stability2 with predictable, sustainable and accurate visual results
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

(-2.70 ±0.94 to -0.52 ±0.63 D)
Stability achieved through advanced haptic design
Outer haptics begin to take up the compression forces of post-operative capsular contraction
Outer haptics engage the inner haptics
Haptic tips gently meet the IOL optic and are effectively locked into position

Manually Loaded Primary IOL Platform
The importance of a high-performance platform.
For over sixty years Rayner has created IOLs with a simple guiding design principle; that our products do not just restore clear vision, but go further - to exceed the expectations of both cataract patient and surgeon.
Characterised by accurate, predictable, and sustainable refractive outcomes supported by 10 years of positive clinical data and the world’s longest commercial history of IOL design & manufacturing, the C-flex platform is one of the highest quality and best-designed monofocal IOLs on the market.
Today, the Rayner primary IOL range continues to deliver on our promise, with an innovative portfolio of monofocal, toric and multifocal IOLs based on this single, proven platform

Peace of mind with low rates of posterior capsular opacification (PCO)
Rayner's 360° Amon-Apple Enhanced Square Edge creates a physical barrier to prevent epithelial cell migration7
| ND:YAG CAPSULOTOMY RATES7 | MEAN TIME TO ND:YAG CAPSULOTOMY7 | |
