title: [The Use of Polymers for Intraocular Lenses in Cataract Surgery].
abstract: According to the World Health Organization, cataract remains the leading cause of the curable visual impairment worldwide. Cataract can only be cured by surgery during which the cloudy lens is replaced with an artificial intraocular lens. It is one of the most common surgeries being performed worldwide. There are age-related, congenital, traumatic and metabolic types of cataract which have been distinguished. Age-related cataract is the most common one and it affects people over 60 with the greatest frequency. In reference to patients whose cornea does not fulfill the requirements for a standard refractive surgery, the number of refractive intraocular lens replacement is increasing. Manufacturers aim to enhance materials in order to minimize surgical complication while increasing the patient’s eyesight. The increase in average lifespan along with patients’ expectations stimulate competition among manufacturers who bring new products and solutions into to the market. There is an augmented demand for premium lenses such as toric, multifocal or accommodating. These lenses bring patients the promise of life without the need for wearing glasses. As far as the main materials used in the production of intraocular lens are concerned, there are hydrophobic, hydrophilic, acrylic and silicone lenses in use. In this paper the author discusses characteristics as well as advantages and disadvantages of the above-mentioned materials. The associated surgical complications and the new areas of development regarding the materials used in lenses manufacturing are also examined.
