Our practice now uses AcrySof ® Natural IOLs in cataract surgery. These state-of-the-art lenses not only block ultraviolet light like other IOLs but also filter blue light. Research suggests that blue light may contribute to Age-Related Macular Degeneration (AMD), a progressive, irreversible disease that is one of the leading causes of blindness. Previously, patients lost the ability to filter blue light after cataract surgery, possibly increasing their risk for AMD. AcrySof lenses reduce this risk without affecting color perception or the ability to see in dim light.
