LISA tri trifocal

(Zeiss)

139 views

LISA tri is a trifocal intraocular lens. At 6 meters, compared to a monofocal intraocular lens, it appears slightly blurry, as if foggy. As the target gets closer, it gradually becomes blurry, then becomes clear again at about 110 cm, blurs again, becomes clear at about 52 cm, and then appears blurry again.

Vision through the mobile model eye

LISA tri, Day, Building (pupil 3.8 mm)

Compared to a monofocal intraocular lens, distant buildings appear slightly hazy, as if covered in fog. This is a phenomenon typically seen in diffractive multifocal intraocular lenses.

LISA tri, Night, Building (pupil 4.8 mm)

At night, the glare around bright lights appears prominent compared to a monofocal intraocular lens. This is a phenomenon typically seen with diffractive multifocal intraocular lenses. It appears more prominent when the pupil size is larger.

The LISA tri is a trifocal intraocular lens.
At 6 meters, compared with a monofocal intraocular lens, it appears slightly blurred as if foggy.
As the optotype gets closer, it gradually blurs, then becomes clear again at about 110 cm, blurs again, becomes clear at about 52 cm, and then blurs again.

LISA tri, nighttime road, pupil (4.8 mm)

This is a video actually filmed on the road at night while carrying a portable model eye.
Compared with a monofocal intraocular lens, halos are seen around bright lights (traffic lights, vehicle headlights, tail lights).
This is a phenomenon typically seen with diffractive multifocal intraocular lenses.
It appears more prominent when the pupil is large.

The specifications above are based on data provided by the IOL manufacturer or its distributor.
An IOL with a higher refractive index is thinner at the same dioptric power.
Abbe number: measured for optics exposed to air; a higher value means less chromatic aberration.
