The CT ASPHINA family, one of the most implanted IOLs of the ZEISS IOL portfolio, offers different optical concepts to meet individual surgeon preferences. The IOLs are designed for quick unfolding and self-centering after implantation, providing the surgeon confidence in the outcome of the procedure.

Aspheric concepts of the ZEISS CT ASPHINA family
Spherical aberration is a common optical imperfection that can decrease contrast sensitivity and lead to blurred vision. In a young eye, the corneal and crystalline lens aberrations tend to cancel each other. Based on this principle, the ideal IOL does not only yield low optical aberrations, but is also able to compensate for corneal aberrations, just like the natural crystalline lens.
Aspheric, aberration-neutral IOLs
ZEISS CT ASPHINA 409M/MP
Features:
Neutral to the cornea
Does not induce spherical aberration
Less sensitive to decentration and tilt
Suitable for patients regardless of their corneal shape and pre-existing lens conditions (e.g. for post laser vision correction patients)
Aspheric, aberration-correcting IOLs
ZEISS CT ASPHINA 509M/MP
Features:
Designed to offset the positive spherical aberration of an average cornea
Induces negative aberration in order to compensate positive spherical aberration of the cornea
Improved contrast sensitivity particularly when the pupil diameter is large (mesopic & scotopic conditions)
Suitable for patients with regular corneal aberrations
Optical quality and expertise, set to achieve high tolerance in case of decentration, ensuring excellent contrast and limited impact of MTF (Modular Transfer Function).
Implantation of the ZEISS CT ASPHINA is straightforward. (…) There is little to no learning curve, and In my experience, there is no eye for which the ZEISS CT ASPHINA 409 M/MP is not suitable.2
Easy implantation to optimize your workflow
The preloaded injector System of the BLUEMIXS 180 supports a controlled and linear injection with an easy access for IOL loading.
