IOL Solutions
for the Highest Standards

Our multifocal IOLs use innovative EPS technology. Elevated Phase Shift delivers optimised image quality with fewer visual disturbances and outstanding trifocal performance.[1] Our multifocal IOLs can provide the highest possible level of spectacle independence.

Thanks to Wavefront Linking technology, 1stQ EDOF IOLs for the capsular bag provide an extended range of focus with minimised dysphotopsia.[6,7] They also offer high visual quality with lower Light Distortion Index values than other commonly used intraocular lenses.[6,7] Our EDOF lenses can provide substantial spectacle independence, although reading glasses may be required for near vision.

Our Mono+ IOLs use an optical design optimised for depth of focus, extending the range of focus of a monofocal intraocular lens into the intermediate range, with a monofocal dysphotopsia profile. MonoPlus can offer cataract patients a clear improvement in visual comfort. However, glasses will still be needed.

The AddOn^® is an IOL implanted in the sulcus in addition to an intraocular lens in the capsular bag. It can be implanted subsequently in a pseudophakic eye to correct residual refractive error or extend the range of focus using multifocal or EDOF optics. In modern refractive lens surgery, a monofocal or monofocal toric capsular bag lens is increasingly implanted together with a trifocal sulcus lens during the same procedure.
This dual lens procedure Liberty² offers a flexible approach to presbyopia correction for greater spectacle independence. AddOn^® IOLs are atraumatically reversible and can be explanted or exchanged for another AddOn^® even many years later.[4,5] ^(4,5) In addition, AddOn^® IOLs are compatible with any commercially available capsular bag IOL.

AddOn^® IOLs feature a patented haptic design developed specifically for the sulcus. Their four flexible haptics work on a “car-jack principle”, making AddOn^® IOLs suitable for almost any sulcus shape.
Their non-torque design also provides high rotational stability.[8,9] ^(8,9) The square lens design prevents iris capture.[10]⁽¹⁰⁾ Rounded edges prevent iris chafing and pigment dispersion, while the convex–concave optical design prevents contact with the Basis IOL in the capsular bag.[10]⁽¹⁰⁾

Depending on the model, Basis IOLs for the capsular bag are available in three different haptic designs: multi-loop haptics (Basis Q), C-loop haptics (611 HPS, Basis V), also available in a fenestrated version (Basis B), and Z-haptics (Basis Z). These haptics provide secure and stable positioning within the capsular bag.

• Our intraocular lenses are manufactured from high-quality hydrophilic or hydrophobic acrylic materials that enable uncompromised visual quality.
• The IOL material has a high Abbe number (58), reducing chromatic aberration and providing high image quality.[2]⁽²⁾
• The refractive index is 1.46 for hydrophilic IOLs and 1.47 for hydrophobic IOLs, close to that of the crystalline lens. A low Tg value (glass transition temperature) of 4°C in the hydrophobic IOLs facilitates handling and gentle unfolding during implantation.
• 1stQ IOLs for the capsular bag feature a continuous 360° edge that acts as a cell barrier, providing enhanced protection against posterior capsule opacification.
• A UV filter is integrated into all 1stQ intraocular lenses as standard.
• Most of our capsular bag IOLs are also available with a Natural Yellow blue light filter to provide natural colour perception and enhanced retinal protection.

Both the hydrophobic and hydrophilic materials used in our IOLs are biocompatible. For example, uveal biocompatibility has been confirmed for our AddOn sulcus IOLs, and they have been shown not to cause inflammatory reactions.[2] ⁽²⁾

We offer capsular bag IOLs in both preloaded and non-preloaded versions.

• With the preloaded system, the injector is preloaded with a foldable hydrophobic intraocular lens. This reduces preparation time, shortens surgery and increases safety.
• Non-preloaded IOLs are supplied with a compatible injector for manual loading. A wide range of optics, materials and designs is available.

Overview and handling instructions for our preloaded IOLs and non-preloaded IOLs.

Our AddOn^® IOLs are supplied non-preloaded with a compatible injector for manual loading. Visit our service section for detailed guidance on preparing the AddOn^® intraocular lens for injection. There you will find instructions and videos on handling 1stQ AddOn^® IOLs. If required, we can also provide on-site support in the operating theatre for handling the AddOn^®. Please contact us to discuss your needs.

Match & Mix is a development of the traditional Mix & Match approach, in which a different IOL model is implanted in each eye.
The specific advantages of the individual IOL optics are intended to complement one another, providing excellent visual performance from distance to near, with further reductions in dysphotopsia and optimised contrast vision.[1–4] With Match & Mix, the innovative RALV^® device enables patients to experience selected IOL combinations before surgery,[1,2,5] setting it apart from the traditional approach.
