AcrySof® Natural - The innovative intraocular lens with blue-light-filter

Harm to the retina by blue light

Besides ultraviolet rays presumably another proportion of sun light is responsible for eye damage: the proportion of blue. Blue light is short-wave (400 to 470 nm) and therefore very energy-rich. Against this proportion of blue there is a natural shield protecting our eyes: the macular pigment (so to speak our sun glasses against blue light). Unfortunately its downside is that it disappears with the passing of the years. Still our body is able to fend for itself. Over the course of our lives - with ageing - a yellow lens pigment is developed which works as a protective filter. It narrows the proportion of the blue light and thereby reduces the risk of retinal damage.

Blue-Light-Filter

If this natural protective filter is removed during cataract surgery the eye should not be left vulnerable to the influence of the blue light without any protection. Especially young cataract-patients and patients with age-related macular degeneration (AMD symptomatology) distinctively benefit from a intraocular lens with additional blue-light-filter as e.g. the AcrySof® Natural as well as the AcrySof® IQ have it. This blue-light-filter simulates the natural lens's filtering characteristics in this way taking over the protective function for the retina.
