- Multifocal IOL Lab.

Model: Artis Symbiose (Crystalens, France), diffractive multifocal IOL, 20D, clear, 4 haptics

Artis Symbiose (Crystalens) USAF resolution target image at each distance, pupil 3.8 mm

With the Artis Symbiose, the image was hazy compared with that of the monofocal IOL at 6 m. Blurring was observed as the model eye got closer and the image became clear again at approximately 60 cm. Subsequently, the clarity decreased as the distance decreased.

Artis Symbiose (Crystalens), night street, pupil 4.8 mm

This video was taken at night, using a mobile model eye. Compared to a monofocal IOL, halos are visible around bright lights (traffic lights, headlights, taillights) with Artis Symbiose This is a typical phenomenon seen with diffractive multifocal IOLs. The larger the pupil, the more pronounced the halos are.

Compared to monofocal IOLs, a distant buildings appears slightly hazy, as if in a fog with Artis Symbiose IOL. This is a typical phenomenon seen with diffractive multifocal IOLs.

With Artis Symbyose IOL, halos around bright lights are more noticeable than with a monofocal IOL at night. This is typical of diffractive multifocal IOLs. Larger pupils make it even more noticeable.
