Model: Zeiss, At Lisa tri 839MP, 20D, diffractive multifocal, trifocal, hydrophilic, plate haptic, clear

Lisa tri is a trifocal IOL. With the Lisa tri, 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 110 cm. Subsequently, the clarity decreased as the distance decreased. Image became clear again at approximately 52 cm. Subsequently, the clarity decreased as the distance decreased.

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 Lisa tri. 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 Lisa tri IOL. This is a typical phenomenon seen with diffractive multifocal IOLs.

With Lisa tri 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.
