Lens Implants and UV Precautions

We've previously mentioned how the lens of the eye not only generates near focusing power (accommodation) it also serves as a critical lifelong UV barrier that protects the delicate the retina from these toxic light rays. Invisible ultraviolet light is blamed for postoperative retinal swelling and the progression of Age-Related Macular Degeneration.

Cataract surgery results in the removal of the lens. This leaves the retina vulnerable. Intraocular lenses (IOLs) are implanted to restore the optics of the eye and to restore protection from ultraviolet light. So-called Blu-blocker IOLs are tinted yellow and are very effective, however, like wearing yellow sunglasses all day, color perception contrast sensitivity are distorted.


Now there's a new IOL, the Smart Yellow IOL. Check out the photo. The IOL on the left is a yellow Blu-Blocker. The Smart Yellow IOL only turns yellow while it is actively exposed to UV light. The rest of the time the Smart Yellow IOL is transparent and the user is symptom free.

If cataract surgery is in your future (or someone close's future!) make sure an effective UV blocking IOL is chosen, even if you need to pay a little extra. You have the right to expect (demand) this level of care. Given that cataract surgery is offered to improve eyesight, it is only logical that every step be taken to optimize the postoperative visual outcome and to protect the eyesight in the future.


Regardless of specific product chosen, this investment will generate 'visible benefits' for the rest of your life.
