Yellow intraocular lenses
How does the natural filter of the eye work?
The human eye has natural UV protection. In addition, the natural eye lens stores yellow pigments in the course of a lifetime. These also protect the eye from the high-energy blue components of visible light, which can lead to long-term damage to the retina (age-related macular degeneration, or AMD for short).
How can you protect your retina after cataract treatment?
In a standard cataract treatment, the natural eye lens is replaced by a colorless IOL. Although this protects the eye from UV radiation, the filter function from shortwave, aggressive blue light is lost.
Yellow intraocular lenses can counteract this adverse effect. The yellow coloration imitates the filtering function of the natural eye lens: The potentially dangerous blue component of the incident light is filtered out and does not reach the sensitive retina. Possible damage can be prevented. An intraocular lens with a blue light filter can be a sensible option, especially for young cataract patients and patients with an increased risk of AMD.
Which IOLs are available with yellow coloration?
We at HumanOptics offer both our standard IOLs and premium IOLs with yellow coloration. After consultation with your ophthalmologist, you can choose whether you prefer a clear or a yellow IOL.
The yellow coloration of the IOLs in HumanOptics imitates the absorption behavior of the natural eye lens (see figure): the harmful blue component of the incident light is filtered out and hence does not reach the retina.
