Lenses are intraocular

Intraocular lenses are applied at treatment of a cataract. We can thank for this break in medicine the English ophthalmologist-surgeon Ridley working during World War II. He noticed that at hit and even presence some time in tissues of an eye of parts of plastic of an inflammation does not occur. This opening was an incitement to creation of materials for an artificial crystalline lens. Intraocular lenses (IOL) happen different types and have respectively various indications for treatment of these or those diseases. Usual monofocal IOL are made of biocompatible material owing to what the risk of development of a secondary cataract decreases to a minimum. There are also intraocular lenses with the yellow optical filter. With age the crystalline lens of an eye of the person gets a yellowish shade that is natural protection of tissues of retina against dangerous influence of ultra-violet radiation. Application of this type of lenses thanks to the similar mechanism of protection reduces probability of development of a makulodistrofiya. It is one of the IOL most widespread models.
