The first hydrophobic lens without compromise for mini-incisions

  • First-in-class material & unique patented design make the difference
  • Easy implantation – 2.2 mm incision
  • SEMTE – An exceptional innovative hydrophobic material

Bi-Flex HB is manufactured from a long-time proven SEMTE hydrophobic co-polymer material:

  • A co-polymer with reduced tackiness compared to other hydrophobic materials
  • Improved mechanical and rheological properties at room temperature – optimal glass transition temperature (Tg) at 4°C
  • Excellent pseudo-plasticity for quick centration and positioning of the injected lens
  • Low rate of cell adhesion – enhanced PCO prevention


  • Smooth continuous gliding of the IOL inside the cartridge, low injection force
  • Gentle but quick, symmetric and atraumatic unfolding in the capsular bag (“like hydrophilic IOLs”)

First-in-class material for an excellent optic quality and improved safety - 100% glistening free:

  • Hydrophobic acrylic IOLs do not need to be packed & stored in water.
  • SEMTE’s refractive index (1.47) closer to the physiological refractive index of the aqueous humor.
  • Medicontur hydrophobic IOLs are lathe cut – not molded.

Why accept materials with a low Abbe number?

  • Bi-Flex HB material & the 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.
  • Chromatic aberration reduces image quality in visible white light because each of its color wavelengths refracts differently.
  • Excellent optical performance
  • Bi-Flex HB presents the highest Abbe number: 58
  • A unique & patented 360º square edge that deserves its name
  • A unique & patented design for perfect centration & long-term stability
  • An arc of contact as large as possible and perfectly balanced haptic forces result in long-term centration and stability.

Bi-Flex HB benefits from the Medicontur Flex-IOL platform design characteristics:

  • Reproducible centration
  • Axial, radial and rotational stability
  • 2 x 90° = 180° arc of contact

Medicontur Natural Yellow Filter
The natural yellow filter offers the required protection while preserving the quality of vision.
Violet and blue light corresponds to visible light wavelengths between 390 and 495 nanometers. 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).
