C-flex & Superflex Monofocal

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 C-flex IOL provides proven rotational and centrational stability, and excellent fixation in the capsular bag¹
• Superb centration
  – Maximum offset of only 1 mm three months after surgery²
• Excellent rotational and torsional stability
  – 3.1° mean IOL rotation three months after surgery²

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

• Uniquely designed loading bay with an extension “lip” to facilitate loading.
• Soft plunger tip completely fills the nozzle and offers a soft protective interface with the IOL.
• Syringe-style design for single-handed technique for smooth IOL delivery with predictable and efficient insertion, ensuring consistent IOL implantations.
• Sterile single use, ready to use.
