A Study was conducted to determine whether the use of a blue light-filtering intraocular lens (IOL) prevents the onset of wet age-related macular degeneration (AMD). More precisely, the proportion of blue light-filtering IOL in a wet AMD patients’ sample was examined and compared it with a general North American pseudophakic population sample.

Wet AMD was detected and treated in case patients, as well as those who had an IOL implanted at least three years prior to the diagnosis of wet AMD. Control patients were chosen at random from among cataract surgery patients. They were free of AMD and were matched for cataract surgery year, sex, and age. Each trial group contained a total of 196 patients.

Results:
--Among patients with wet AMD, 62.8% had a blue light-filtering IOL compared with 63.3% among control patients.

--Mean time between implantation and injection of anti-VEGF in AMD patients was 6.62 years in non-blue light-filtering IOL group and 5.76 years in blue light-filtering IOL group.

Finally, there was no evidence of a link between the presence of a blue light filter in the IOL and the development of wet AMD. Patients with AMD who did not have a blue light-filtering IOL were injected much later than those who did have a blue light-filtering IOL, contradicting the blue light filter's possible clinical advantage.
