Do blue light filtering intraocular lenses affect visual function?

Conclusions: This study showed no significant effects of a blue-light filtering IOL on visual acuity and no influence on color perception and CS. After more than 2 years, there were no significant differences in macular changes between the IOL groups.

Can intraocular lens be colored?

In ophthalmologic practice, cataract surgeons can now select any one of three types of IOL, namely those that block UV, violet, or blue light. Previous studies reported that both UV- and blue-light-blocking IOLs had beneficial effects on systemic health in terms of vision-related QOL, sleep quality, and gait speed.

Do I need blue light glasses after cataract surgery?

Improved blue-light transmission after cataract surgery may enhance cognitive function in older patients, a study found. The study authors used reaction time tasks to gauge objective improvement in cognitive function after cataract surgery and IOL implantation.

Do intraocular lenses have UV protection?

Although most IOLs do reduce transmission of UV radiation, BLF IOLs are “different than typical UV-filtering IOLs because of the addition of short-wave light filtering to their absorbance profile.” Any IOLs without adequate UV absorbance could lead to retinal damage among those who received cataract surgery.

Why do I see blue after cataract surgery?

This happens due to increasing cataract. Replacing the crystalline lens with an artificial intra ocular lens increases blue light transmission. Patients often comment that everything looks ‘bluer’ after cataract surgery. This is normal and brain adapts to this in some time.

Do Cataracts block blue light?

The clear eyes of children and those who’ve had cataract surgery may be more susceptible to damaging rays. Many of the lenses placed in the eye at the time of cataract surgery now have blue light filters in the them.

Can IOL correct astigmatism?

To treat astigmatism that is more severe, the cataract lens is replaced with a special intraocular lens (IOL), called a toric IOL. These lenses correct astigmatism as well as nearsightedness or farsightedness.

Do eyes look different after cataract surgery?

After cataract surgery, expect your vision to begin improving within a few days. Your vision may be blurry at first as your eye heals and adjusts. Colors may seem brighter after your surgery because you are looking through a new, clear lens.

Can you see UV light after cataract surgery?

Even with the lens removed (a condition known as aphakia) the patient can still see, as the lens is only responsible for about 30% of the eyes’ focusing power. However, aphakic patients report that the process has an unusual side effect: they can see ultraviolet light.

What is UV with blue light filter?

Blue-light filtering intraocular lenses are purported to reduce the incidence of potentially damaging UV and blue light on the retina. This article reviews their background, the proposed benefits on long-term eye health and the possible disadvantages on circadian rhythm, scotopic vision and colour vision.

Which is an example of a blue blocker lens?

The Acrysof IQ Intraocular Lens (IOL) is an example. All currently available artificial lenses filter ultraviolet (UV) light, which is harmful to the retina in the eye. The Acrysof IQ IOL filters both UV light and high-energy blue light.

Are there any eyeglasses that block blue light?

The Acysof IQ lens incorporates a patented chromophore that blocks harmful blue light and UV light in much the same way as our natural lens does prior to developing cataracts. The FDA clinical studies showed no adverse side effects on color vision or quality of vision.

Which is the best blue blocker for cataract surgery?

The Acrysof IQ (Blue-Blocker) IOL enhances the benefits of advanced cataract surgery by filtering out harmful blue light and, thus providing a replacement lens that protects the retina more like your natural lens.

Are there any studies on blue light filtering IOLs?

And, in fact, previous to 2009, the studies were inconclusive. However, a new study by Gray and colleagues, currently in press in Journal of Cataract and Refractive Surgery, found that patients with blue-light filtering IOLs performed significantly better under driving conditions with glare compared with similar patients who had clear IOLs.
