Is Blue Light Special? (part 3 of 4)
Reasons why it might not be such a great idea to implant a blue-blocking IOL into the eye.

Why place a blue-blocking IOL in the eye? Does a blue-blocking IOL protect the eye from macular degeneration?
Not everyone agrees that filtering blue light is a good idea. It’s one thing to put on a pair of sunglasses with a yellow tint. But, should we really be surgically implanting these lenses in the eye after cataract surgery?
At room temperature it is shaped like a rod allowing the surgeon to easily slip it through a small incision and into the eye. As the material heats up to body temperature it transforms into a biconvex lens. Truly amazing!
Probably the most unique approach to the problem of presbyopia-correcting IOLs is the mechanism used in the NuLens®. This lens tries to mimic the natural process that occurs in some water birds such as penguins.
This IOL platform, presented by Paul Dougherty, M.D., seemed to have only one benefit over multifocal IOLs: minimal post-operative glare. However, that benefit already exists with the Crystalens® IOL.
