Blue light-filtering increases macular pigment, may protect against age-related vision loss
Date:10/26/2009

lue light is harmful to the retina, increased levels of macular pigment are considered a strong surrogate marker for protection against the processes that cause age-related blindness, including AMD," says Dr. Nolan.

According to the study, the potential benefits associated with increased macular pigment resulting from the use of blue light-filtering lenses for prevention and/or decreased progression of AMD would be conferred at the time of cataract surgery and are expected to continue thereafter, over a patient's lifetime.1 This is especially meaningful in the modern era of cataract surgery, which is being performed annually in millions of older persons who live for many years after the procedure, as well as certain patient subgroups, who have had the surgery at an earlier age.2 The researchers note that further studies are needed to confirm the clinical benefit of their findings.1

About the Study

Dr. Nolan and colleagues conducted a prospective study in which 42 patients scheduled for cataract surgery were randomized to implantation with a blue light-filtering acrylic IOL or a standard acrylic IOL (control), with macular pigment optical density measured by a reliable method (heterochromatic flicker photometry), and serum concentrations of the macular carotenoids were quantified by a scientific procedure known as high performance liquid chromatography, prior to surgery and then at several post-procedural time points over a 1-year follow-up period.1

Cataract surgery in older persons, where the natural diseased lens (cataract) is replaced with a clear artificial IOL, has been associated with increased subsequent risk for macular disease,4 perhaps due to increased transmission of potentially injurious short-wavelength (blue) light to the retina.3

Therefore, lens manufacturers have incorporated a blue light-filter into IOLs to help reduce photo-oxidative
