RayOne® Aspheric

RayOne® Aspheric

When creating RayOne®, we developed our MICS lens and unique patented Lock & Roll™ technology as part of the same design process; this combination has resulted in the smallest fully preloaded injector available (1.65 mm nozzle).

Our new RayOne® MICS lens is an enhanced version of the tried-and-tested C-flex and Superflex platform, combined into a single 6 mm optic design.

We have retained the material and design benefits of our original lenses, without compromising on proven stability or optical performance.

RayOne® Aspheric with the largest fully preloaded power range available. From -10.0 to 34.0 Dioptres.


When considering an intraocular lens, what’s important to you?

Reliable optical outcomes and a low rate of post-operative complications


Designed with Rayner’s Anti-Vaulting Haptic (AVH) Technology®. Our RayOne® IOL provides proven rotational and centrational stability, and excellent fixation in the capsular bag1

  • Superb centration
    • - Maximum offset of only 1 mm 3 months after surgery2
  • Excellent rotational and torsional stability
    • - 3.1° mean IOL rotation 3 months after surgery2

Aberration-neutral technology for optimal visual quality and functional visual acuity in all light conditions


Designed with an aspheric anterior surface that creates no spherical aberration. Studies have demonstrated that aberration-neutral technology:

  • Offers improved contrast sensitivity compared with spherical IOLs3,4
  • Provides better low light level visual acuity than spherical IOLs14
  • Can offer more depth of field than aberration-negative IOLs by retention of the patient’s natural level of corneal spherical aberration6
  • Are less susceptible to the effects of decentration than aberration-negative IOLs11
  • Twice as many patients* preferred the aberration-neutral IOL than aberration-negative6
  • Three times fewer reports of visual disturbances with the aberration neutral IOL than aberration-negative6

Reducing dysphotopsia by design12

  • Rayner’s Enhanced Square Edge Technology shows no general increase in glare from previous models without a square edge7
  • 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 7,5
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

Vacuole free material for a glistening free IOL

  • Single piece IOL created from Rayacryl® an homogeneous material free of microvacuoles, resulting in a glistening free IOL8
  • Compressible material for delivery through a micro incision
  • Excellent handling characteristics with controlled unfolding within the capsular bag
  • Low silicone oil adherence9
  • Excellent uveal biocompatibility13
  • Hydrophilic acrylic material with low inflammatory response10
