Medicontur ELON Wavefront Linking


Bi-Flex ELON

ELONgated Depth of Focus

Wavefront Linking

Central concentric refractive zones varying in curvature linked by specially designed linking zones. Continuous light energy is distributed along the optical axis with connected focal points, delivering singular elongated focus across the entire range of vision.

Bi-Flex Platform

The ELON lens is equipped with the proprietary Bi-Flex design for long-term stability and centration. The large contact angle between the lens haptics and the capsular bag wall ensures long-term stability and visual comfort.

Hydrophobic Material

SEMTE hydrophobic copolymer material, ensuring high uveal biocompatibility and low levels of glistening.

Excellent visual quality

The Medicontur Bi-Flex ELON lens provides excellent contrast sensitivity along the whole defocus range.

Presbyopia correction

Preliminary clinical experience suggests that Medicontur Bi-Flex ELON can be used in presbyopia correction in patients with mild ocular pathologies or previous ocular surgeries.

Continuous range of vision

Patients can lead an active lifestyle independent of spectacles. ELON delivers high-quality vision for far and intermediate distances. Glasses may be required for near vision.
