Intensity IOL (Hanita lenses)

Model: Hanita lenses (Israel), Diffractive multifocal, 20D, hydrophobic, pentafocal, clear

Intensity IOL, USAF resolution target image at each distance (pupil 3.0 mm)

Intensity lens (Hanita lenses) is known for its pentafocal lens (five foci). At 6 meters, USAF resolution target appears slightly hazy compared to a monofocal IOL. Blurring was observed as the model eye got closer. From about 70 cm to about 40 cm, resolution target becomes clear. Subsequently, the clarity decreased as the distance decreased. It’s difficult to clearly distinguish the five focal points.

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 Intensity IOL (Hanita lenses). 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 Intensity IOL (Hanita lenses). This is a typical phenomenon seen with diffractive multifocal IOLs.

With Intensity IOL (Hanita lenses), 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.
