13 July 2004 Macular protection with IOLs
Author Affiliations +
The clinical outcome within one month after phacoemulsification cataract extraction with implantation of the blue-blocking SN60AT IOL was examined prospectively and compared to a retrospectively examined material of implantations of the equivalent SA30AL without blue-blocker. There was no difference in best corrected visual acuity gain between the two lenses. In addition, the subjective color perception was examined for with a questionnaire after the first implantation of blue-blocking IOL and after the second implantation of blue-blocking IOL. Only one patient noted a changed color perception. There are thus strong theoretical reasons to block blue light in IOLs and no short term clinical inconvenience. But, it remains to be proven in long term follow up studies that the blue-blocking IOL protects against macular degeneration.
