C-flex & Superflex Aspheric Monofocal

Patients deserve optimal visual quality and functional visual acuity in all light conditions

Aspheric IOL with aberration-neutral technology:

• Offer improved contrast sensitivity compared with spherical IOLs^3,4
• Provide better low light level visual acuity than spherical IOLs¹⁸
• 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 IOLs¹²

Why is it important to retain depth of field?

Patients prefer a lens that retains depth of field⁶

• Retention of some positive SA can provide up to 0.5 D of pseudo-accommodation, offering preferable visual outcomes

– In a clinical trial of 80 patients where an aberration-neutral lens was implanted in one eye and an aberration-negative lens was implanted in the other eye:⁶

• 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.
