Crystalens AO Intraocular Lens

Crystalens Logo

Crystalens AO Lens is an artificial lens implant that can treat both a person's cataracts and presbyopia —the clouding or hardening of your lenses, and the loss of near and intermediate vision, respectively. Crystalens was modeled after the human eye. Like the natural lens, it is a lens implant that uses the eye muscle to flex and accommodate in order to focus on objects in the environment at all distances. Crystalens dynamically adjusts to your visual needs. Many patients hardly, if ever, need glasses after surgery.

Outstanding Vision Quality

The Crystalens AO brings together Bausch + Lomb’s innovative accommodating lens technology and its proven aspheric lens design. The accommodating aspheric IOL is designed to deliver premium vision at all distances without any compromise in intermediate vision. Additionally, because the Crystalens AO is aberration free, patients can enjoy best-potential visual quality with enhanced contrast sensitivity.


The Benefits of an Aspheric Design

The Crystalens AO is designed to be free of spherical aberration for better visual quality relative to standard spherical IOLs.1 More predictable and repeatable refractive outcomes with a broader patient population can be expected.2


Uniform Centre-to-Edge Power

Optical performance is unaffected by pupil size or location of the optic due to uniform centre-to-edge power.1,2


Excellent Contrast Sensitivity

Patients should experience their best-potential postoperative visual quality with enhanced contrast sensitivity; particularly important in low light or night time conditions.


Uncompromised Intermediate Vision

The Crystalens AO is optimised for lifestyle vision, so objects at intermediate distances are as clear as objects that are near or far.


Outstanding Vision Quality

The Crystalens AO accommodating, monofocal lens delivers 100% of available light rays at all distances, which means patients can see near, intermediate and distant objects with equal clarity. The IOL, like the natural crystalline lens, creates accommodation from distance to near vision by moving along the visual axis. Both the natural lens and the Crystalens AO also arch, or change their radius of curvature, to increase their accommodation. They both move anteriorly and flex or arch to increase their focusing power in intermediate and near ranges.
