Verifying refractive outcomes and ensuring long-term reliability


Verifying refractive outcomes and ensuring long-term reliability

Increasing patient expectations for long-term reliable outcomes

Clinical challenge

As the average age of cataract patients is declining1, surgeons need to cater to increasing patient expectations and provide long-term solutions.2

Yet, particularly after the removal of hard cataracts, higher rates of inflammation and edema can be experienced.3 In the long-run, dislocated IOLs or dysphotopsias4 may cause headaches  – both to the surgeon and the patient.

Reliability in post-op check up and long-term refractive outcomes

Clinical solution

As the extraction of hard cataracts is associated with higher post-op complications, thorough post-operative diagnostics are vital.3 Trusted technologies are slitlamp and OCT. To ensure life-long tolerability of the implant as well as an excellent patient outcome, an optimal IOL needs to be chosen. Hydrophilic IOLs have a great biocompatibility which is especially important in eyes with a damaged blood-aqueous barrier (from uveitis, glaucoma, diabetes).5

Additionally, inflammatory cells accumulate less easily on hydrophilic IOLs than hydrophobic IOLs. Dysphotopsias also occur less in hydrophilic lenses, as they have a lower refractive index compared to hydrophobic IOLs.6 Specifically IOLs with a 4-point haptic design are a trusted platform for excellent centration and stability in the bag.7

Premium optical quality – ZEISS IOL technology and post-op diagnostic device

ZEISS solution

The ZEISS CT ASPHINA family, one of the most implanted IOLs in the ZEISS hydrophilic IOL portfolio, provides predictable and stable refractive results. The SL 800 slit lamp from ZEISS equips you with an all round setup for the observation of anterior and posterior segments.



The ZEISS CT ASPHINA 409 is designed for quick unfolding and self-centering after implantation, providing you confidence in the outcome of the procedure.

  • Reliable 4-point haptic design developed to provide predictive outcomes due to its self-centering ability
  • Suitable for patients regardless of their corneal shape and pre-existing lens conditions
  • Does not induce spherical aberration
