A cataract is a term used to describe a clouding of the eye’s lens, and can be classified as: congenital, juvenile or senile (depending on the age of the patient). Even though the causes of cataracts can be well defined, in most cases the reasons for their occurrence is unclear, so they are usually simply associated with ageing. Epidemiological studies suggest their occurrence to be connected with a person’s age. The prevalence of cataracts rises by about 50% in individuals 65 to 74, to about 70% in those over 75 years of age. Cataracts may also occur due to: trauma, metabolic diseases (diabetes mellitus, galactosemia), medication (corticosteroids). Cataracts are also known to occur as a complication with other eye conditions (uveitis, glaucoma) and can appear in individuals with Down’s syndrome.
Today’s modern approach to cataract surgery significantly shortens the period a patient has to be hospitalized from seven days to a single day, which considerably reduces hospital expenses and the period the patient needs to recover. Phacoemulsification (PHACO) and intraocular lens (IOL) implantation is a highly preferred method of cataract surgery.
Every cataract surgery requires the implantation of an intraocular lens which replaces the patient’s clouded lens, that is, the cataract. To eliminate glasses you can choose among variety of multifocal lens.
