AddOn® toric-trifocal

clear hydrophilic non-preloaded

The AddOn toric-trifocal is a sulcus lens for post-corrections or upgrades across the entire optical spectrum for pseudophakic eyes – with a spherical equivalent of -3 D to +3 D SEQ and cylinder corrections of
+1 D to +4.5 D as well as a +3 D addition for near vision.

Single-use manual injector for the implantation of an AddOn IOL into the sulcus.

Recommended incision size

From 1.8 to 2.4 mm, depending on the cartridge size. Recommended for AddOn: 2.0 to 2.4 mm.

Packaging

Cartridge + injector in blister; 1 disposable injection kit per box.

Plunger

Silicone plunger for push injections.

Shelf life

3 years after sterilization.

Cartridge

Special click-lock system and guide rails for the easy placement of the lens.

The upgrade for
pseudophakic eyes

The patented sulcus lens for optimized refraction results or subsequent upgrades for increased spectacle independence.

What users are saying

“I use the AddOn lens frequently in clinical practice to expand my options for refractive upgrades or corrections because of its dependable stability.”

Sathish Srinivasan MD, FRCSEd, FRCOphth, FACS, United Kingdom

“I feel very comfortable and safe with planned two-stage trifocality with a Basis IOL in the capsular bag and a trifocal AddOn in the sulcus. The superindication for this technique is RLE or post-LASIK cataract surgery. Refractive surprises should thus be entirely eliminated.”

Kjell Gunnar Gundersen MD, PhD, Norway

“The AddOn can be used to bring pseudophakic patients back to their visual comfort zone at any time.”

Erik L. Mertens MD, FEBO, Belgium

“The AddOn with trifocal array is just great. In combination with the capsular bag lens it provides a high degree of adaptability to refractive situations. Handling and safety are convincing.”

Prof. Dr. Gangolf Sauder MD, Germany

“The main benefit of implanting a trifocal AddOn lens is the relative ease of reversibility at any given time […]. This is a smart option for patients who are particularly uncertain about how to handle aberrations
from multifocal IOLs.”

Brian Harrisberg MD, MBBCh, FRACS, FRANZCO, Australia

Questions about the AddOn®

Is the AddOn compatible with all customary capsular bag lenses?

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.

Can an AddOn be implanted in each sulcus?

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

How long after cataract surgery can an AddOn be implanted?

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.

How long after implantation can the AddOn be explanted again or exchanged with another AddOn?

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)

Can an AddOn also be implanted in phakic eyes?

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

Can the AddOn also be implanted in a single stage together with a capsular bag lens?

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.
