With the Artis Symbiose multifocal IOL, the image appears slightly hazier, as if foggy, compared to a monofocal IOL. As the target comes closer it gradually becomes blurrier, then becomes clear again at about 60 cm before blurring once more.
Vision through the mobile model eye
Artis Symbiose (Cristalens), day, building, pupil 3.8 mm
With the Artis Symbiose multifocal intraocular lens, distant buildings appear slightly hazy, as if in a fog, compared with a monofocal intraocular lens. This is a phenomenon typically seen with diffractive multifocal intraocular lenses.
Artis Symbiose (Cristalens), nighttime, building, pupil 4.8 mm
With the Artis Symbiose, glare around bright lights at night appears markedly more pronounced than with a monofocal intraocular lens. This is a phenomenon typically seen with diffractive multifocal intraocular lenses. The larger the pupil, the more pronounced it appears.

Artis Symbiose (Cristalens), image of the eye chart at each distance, pupil 3.8 mm
With the Symbiose multifocal IOL, at 6 meters the image appears slightly blurred, as if in a fog, compared with a monofocal IOL. As the target gets closer, it gradually becomes blurrier, then becomes clear again at about 60 cm, and then blurs again.

Artis Symbiose (Cristalens), night road, pupil 4.8 mm
This is a video of an actual nighttime road recording taken with a portable model eye. With the Artis Symbiose multifocal IOL, halos are seen around bright lights (traffic lights, vehicle headlights, taillights) compared with a monofocal IOL. This is a phenomenon typically seen with diffractive multifocal IOLs. It appears more prominent when the pupil is large.

The specifications above are based on data provided by the IOL manufacturer or its distributor.
An IOL with a higher refractive index is thinner at the same dioptric power.
Abbe number: measured for optics exposed to air; a higher value means less chromatic aberration.
