Blue-blocking lens performs like standard UV-absorbing model

San Francisco-The AcrySof Natural IOL (Model SB30AL, Alcon), containing a covalently bonded, blue light-filtering chromophore (ImprUV), more closely mimics the light transmission spectrum of the precataractous adult human crystalline lens compared with standard UV-absorbing IOLs without any adverse effects on vision, said Paul H. Ernest, MD, at the American Society of Cata-ract and Refractive Surgery an-nual meeting.
