The so-called refractive lens exchange is an operation from the spectrum of refractive eye surgery. Here, the lens of the eye is removed and inserted an artificial lens. The procedure is used in an extreme refractive error is used.
The most common and typical reason for a lens exchange is the disease is cataracts, a condition in which the cloudy lens. With wide and long-sightedness is the surgery only for very extreme values in question. At present astigmatism (astigmatism, astigmatism) This method is less.
The surgery typically occurs predominantly in persons from 40 years to apply. The reason given is that the eye with an artificial lens is no longer capable of accommodation, which means it is no longer able to respond strongly at distances of itself. This ability is generally worse with age, so that a lens replacement at a young age is not meaningful.
During surgery, the cornea is first cut through it and open the capsule surrounding the lens. Using ultrasound, the nucleus of the lens is broken and thus removed from the capsule. The rest of the lens is removed by suction to the eye. An artificial lens with a precisely calculated eyesight is used with the help of an instrument into the empty capsule. The refractive lens exchange is considered a very safe procedure. The artificial lens is a life-long service.
As with any surgical procedure, it can also come here to complications. These include the risk of infection during lens exchange, the detachment of the retina and swelling of the center of the retina. All of these complications are very rare.
