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). Bi-Flex lenses are manufactured from a long-time proven 25% hydrophilic copolymer material, which delivers smooth continuous gliding of the IOL inside the cartridge with low injection force. Only an IOL made of first-in-class material can offer constant optic quality & improved safety.

Bi-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.

Specific polish-free process manufacturing and patented design characterize all Bi-Flex IOLs with:

    • a sharp square edge
    • all over 360° including the optic-haptic junction zone

A highly protective “edge effect“ against lens epithelial cell migration.

Comparative scanned images of IOLs marketed with „sharp edge” at the optic-haptic junction
Medicontur Bi-Flex IOL is the only lens which has a real square edge over 360° even at the optic-haptic junction.

A unique & patented design for ultimate centration & long-term stability.
Only a specific design offering a large contact angle and adequate haptics resistance can provide long-term centration and stability. Bi-Flex lenses benefit from all assets of the Bi-Flex platform design characteristics:

  • for reproducible centration of the IOL
  • for axial, radial and rotational stability.

These unique characteristics are the largest contact angle between haptics and capsular bag equator among all IOLs 2 x 90° = Total 180°contact angle.

A 0° angulation to easily remove all viscoelastic gel from behind the IOL after the surgery to improve refraction stability.

An aspheric optical design:

  • to limit optical aberrations
  • to improve patients’ visual comfort.

A first-in-class material with a high Abbe number
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.
Bi-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.
