The Problem: Spherical Aberration

It's a little-known fact that, in spite of all the advances in eye care technology today, even healthy eyes may contain imperfections called higher order aberrations. An aberration is an irregularity in the shape of the eye's refractive surface that can distort vision.

One type of higher order aberration common to cataract patients is spherical aberration, which can lead to a gradual reduction in vision acuity and function. As you get older, your eye's lens gets thicker and rounder, causing image quality to deteriorate.

Spherical aberrations are generally associated with vision problems such as:

• Blurriness
• Halos
• Double vision
• Loss of contrast
• Poor night vision

 
The Solution: AcrySof® IQ IOL

In addition to restoring healthy, cataract-free sight to patients, the AcrySof® IQ intraocular lens (IOL) was developed with a unique aspheric design that actually helps reduce spherical aberration.

As a result, the AcrySof® IQ IOL offers a number of benefits over traditional lenses, including:

• Enhanced clarity
• Improved image quality
• Filtered blue light for rich, vibrant color

This amazing aspheric technology is now also available in the entire AcrySof® IOL family. Say goodbye to bifocals and reading glasses with the new AcrySof® IQ ReSTOR® IOL, which offers enhanced image quality and provides a full range of vision near, far and everywhere in-between. For cataract patients with astigmatism, the new AcrySof® IQ Toric IOL provides astigmatism correction with enhanced image quality.

With innovations like these, it's no wonder that AcrySof® IOLs are the most widely used in cataract surgery, with more than 40 million implanted worldwide.
