Model: Symfony, Johnson&Johnson, diffractive, extended depth of focus, one piece, c-loop
Symfony IOL is a type of extended depth of focus (EDOF) intraocular lens (IOL) developed by Johnson & Johnson Vision (JNJ).
Symfony IOL (Johnson & Johnson) appear like biifocal IOLs. At 6 meters, USAF resolution target appears slightly hazy compared to monofocal IOLs. Blurring was observed as the model eye got closer and the image became clear again at approximately 90 cm. Subsequently, the clarity decreased as the distance decreased. This showed that this lens functions like a bifocal IOL.
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 Symfony IOL (Johnson & Johnson) . This is a typical phenomenon seen with diffractive multifocal IOLs. However, compared to other diffractive multifocal intraocular lenses, the halo around the lights appear to be slightly less.

Compared to monofocal IOLs, a distant buildings appears slightly hazy, as if in a fog with Symfony IOL (Johnson & Johnson). This is a typical phenomenon seen with diffractive multifocal IOLs.

With Symfony IOL (Johnson & Johnson), halos around bright lights are more noticeable than with a monofocal IOL at night. This is typical of diffractive multifocal IOLs. However, compared to other diffractive multifocal intraocular lenses, the halo around the lights appear to be slightly small.
