Q Flex


First-in-class material & unique patented design make the difference

  1. Easy and reproducible injection
  2. Through 1.8mm micro-incision
  3. Long-term axial, radial and torsional stability
  4. Precise and stable refractive results
  5. Improved PCO prevention
  6. Very low chromatic aberration

A first-in-class material for easy implantation through 1.8mm incision. Only a material with specific rheological properties is suitable for optimal micro-incision surgery (MICS). QFlex lenses are manufactured from a long-time proven 25% hydrophilic copolymer material:

  • optimally combining hydrophilic and hydrophobic monomers
  • offering rheological properties required for MICS: ELASTICITY · SOFTNESS · SHAPE MEMORY
  • creating optimal conditions for MICS

Smooth continuous gliding of the IOL inside the cartridge, low injection force. Immediate, symmetric and atraumatic unfolding inside the capsular bag. Only an IOL made of first-in-class material can offer constant optic quality & improved safety.

Q-Flex material offers permanent optic quality as a result of:

  • unequaled transparency
  • very low chromatic aberration thanks to high Abbe number

A unique & patented 360° square edge that deserves its name for improved PCO prevention. Only a real square edge can stop cells migration.

Studies have highlighted the essential role of the optics profile design – especially the existence of a square edge all around the optic – to control cell migration.

A unique & patented design for ultimate centration & long-term stability.
The Abbe number is a measure of a transparent material's dispersion in relation to the refractive index. The higher the Abbe number the lower the chromatic aberration. Q-Flex 1.8 benefits from a very high Abbe number value: 58.

A natural yellow filter for optimized protection against “blue light”. Only a natural yellow filter can offer the required protection while preserving quality vision. Violet and blue light corresponds to visible light wavelengths between 390 and 495 nanometers (nm). It is known that short wavelengths are potentially harmful to the macula. On the other hand we know that blue light is important for the scotopic vision (night driving).

Medicontur natural yellow filter cuts from 390 nm to 470 nm:

  • covering the most critical “high energy” portion of visible light
  • preserving the low energy portion of blue light to maintain scotopic vision capacity, colour and contrast sensitivity.
