Recently, there have been great advances in artificial lens technology. The Acrysof IQ Intraocular Lens (IOL) is an example. All currently available artificial lenses filter ultraviolet (UV) light, which is harmful to the retina in the eye. The Acrysof IQ IOL filters both UV light and high-energy blue light. Clinical studies have shown that high-energy blue light causes oxidative damage to the retina and may be a risk factor for developing macular degeneration. The Acysof IQ lens incorporates a patented chromophore that blocks harmful blue light and UV light in much the same way as our natural lens does prior to developing cataracts. The FDA clinical studies showed no adverse side effects on color vision or quality of vision. The Acrysof IQ IOL inserts through a micro-incision that requires no stitches, and it is designed to conform to the natural shape of the lens capsule. This helps it stay stable and centered in the eye. But what makes the Acrysof IQ IOL unique is its ability to filter blue light. The Acrysof IQ (Blue-Blocker) IOL enhances the benefits of advanced cataract surgery by filtering out harmful blue light and, thus providing a replacement lens that protects the retina more like your natural lens. Additionally, this lens is designed with wavefront-guided, aspheric optics that help improve contrast sensitivity and overall visual quality.
