Model: Elana (Zeiss), diffractive multifocal IOL, 20D, clear

An improved version of the previous model, the At Lisa Tri, this lens is hydrophobic and has a C-loop shape that is more familiar to ophthalmologists.

 

Elena IOL (Zeiss) is a trifocal IOL. With the Elana lens, 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 75 cm. Subsequently, the clarity decreased as the distance decreased. Image became clear again at approximately 50 cm. Subsequently, the clarity decreased as the distance decreased.

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

Compared to monfocal IOLs, a distant buildings appears slightly hazy, as if in a fog with Elana IOL (Zeiss). This is a typical phenomenon seen with diffractive multifocal IOLs.

With Elana IOL (Zeiss), 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.
