Accommodating intraocular lens Crystalens®

astigmatismpresbyopiapolydimethylsiloxane

Highlights
Crystalens® AO and Trulign® Toric intraocular lenses provide surgeons options to restore a functional range of vision for near, intermediate and distance tasks while addressing astigmatism where indicated. These lenses use distinct optical and mechanical features to deliver clinical outcomes relevant to cataract patients.

Accommodation
Sharp vision at distances that matter
Crystalens® AO is an accommodating IOL that maintains one distinct point of focus by changing position and functional power within the capsular bag rather than splitting light. This approach supports distance, intermediate and some near vision with reduced risk of diffractive-type positive dysphotopsias.

Nighttime Vision
Clear nighttime vision
The Crystalens® AO optic focuses 100% of incoming light to a single point of focus and provides consistent performance in low-light conditions, contributing to minimized starburst and glare compared with diffractive multifocal optics.

AO Optic Design
Exceptional contrast sensitivity

• The aberration-optimized (AO) optic focuses 100% of light while maintaining one distinct point of focus.
• AO design delivers uniform power center-to-edge for consistent acuity, improved low-light visual performance and reduced sensitivity to decentration.

Astigmatism and Presbyopia
Treat astigmatic cataract patients and provide a natural range of vision
Trulign® Toric IOL corrects corneal astigmatism and addresses presbyopia effects to provide intermediate and distance vision useful for everyday activities. The lens offers rotational stability, predictable astigmatism correction and effective centration for combined astigmatic cataract correction in a single procedure.

Excellent Intermediate and Distance Vision Results (Study data)

• Uncorrected intermediate visual acuity ≥20/25: 86.6% | Uncorrected distance visual acuity ≥20/25: 72.4%
• Uncorrected intermediate visual acuity ≥20/32: 94.1% | Uncorrected distance visual acuity ≥20/32: 86.6%
• Uncorrected intermediate visual acuity ≥20/40: 97.8% | Uncorrected distance visual acuity ≥20/40: 97.8%
