Questions about the AddOn®
Yes, the AddOn is a sulcus lens that is implanted in addition to the capsular bag lens and is compatible with all commonly used IOLs, regardless of their design or material.
Thanks to their patented features(1), such as sulcus fit with 4 flexible haptics and rotational stability thanks to the non-torque design, the AddOn can be adapted to any sulcus size and shape.
(1) Patent #EP12181744
The AddOn lens can be implanted in the capsular bag any time after lens exchange. If a patient subsequently opts for increased spectacle independence, a trifocal AddOn is exactly the right solution.
The AddOn is placed in the sulcus and is therefore non-traumatically reversible at any time – even many years after the initial surgery.(1)(2)

No, the AddOn is only designed and patented for implantation in pseudophakic eyes.(1)

Yes, the AddOn lens can be implanted together with the capsular bag lens in a single surgical intervention. When it comes to achieving spectacle independence for patients, the Liberty2 dual-lens system is worth considering.
