RayOne^® Aspheric

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 IOLs^3,4
• 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

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

For Contact Ultrasound, the estimated A-constant is 118.0 Please note that the constants indicated for all Rayner lenses are estimates and are for guidance purposes only. Surgeons must always expect to personalise their own constants based on initial patient outcomes, with further personalisation as the number of eyes increases.
