An IOL that filters ultraviolet and blue light has been approved for marketing in the United States, according to the company. Alcon’s AcrySof Natural is a single piece IOL “designed to approximate the light filtration properties of a healthy human lens,” the company stated in a news release.
In a clinical trial, 297 patients were randomized to bilateral implantation with either the AcrySof Natural IOL or an AcrySof lens with UV absorption only. Visual acuity outcomes were not statistically significantly different between the two types of lenses, and both types exceeded the standard Food and Drug Administration grid, according to the company. Color perception also was not statistically significantly different between the two IOLs.
“A growing body of evidence shows high frequency blue light may cause retinal damage. Knowing the AcrySof Natural IOL filters out this potentially dangerous light without negative visual consequences, I firmly believe this lens could become the standard for all future IOLs,” said Robert Cionni, MD, medical director of the Cincinnati Eye Institute.
The AcrySof Natural IOL received approval for European marketing in September 2002.
