MATERIAL & DESIGN MAKE THE DIFFERENCE
First-in-class material & unique patented design make the difference
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:
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 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:
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:
A full 6mm optic
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).
