WIOL-CF®

The first bioanalogic IOL that resembles natural crystalline lens in multiple respects.

WIOL-CF® — We got inspired by nature...

Natural young crystalline lens = ideal accommodating IOL WIOL-CF® = the first bioanalogic IOL
Large-diameter optics (9-10 mm effective diameter) enables peripheral vision and vision under low-light conditions Large-diameter optics (8 to 9 mm effective diameter compared to 4,5-6 mm optics diameter for other current IOLs) enablesperipheral vision and vision under low-light conditions
Glare-free optics with antireflective surface Glare-free optics with antireflective surface
Wide accommodation range of up to 10 diopters (decreasing with age, approx. 2 Diopters at the age of 42-50) Accommodation range exceeding 2 diopters with long-term stability of the effect
Implantation through 0 mm incision (grows in situ) Implantation through 2,5 – 2,8 mm incision for most of optical powers
Filling the space between iris and vitreous body Filling the space of the posterior capsule
Hydrogel-like tissue with high negative charge density Hydrogel with high biocompatibility and negative charge
Long-lasting service (typically 40 years including accommodation) Long-lasting service (more than 12 years including accommodation by the current state of documented experience)
UV- absorption capability UV- absorption capability
