Under the generic term lambulatorio eye refractive summarizes the operations that you want to change the total rupture force and replace the eye like conventional optical corrections such as glasses or contact lenses, or significantly reduces the resistance of at least. Loftalmologia know several methods of operation for the correction of ò Ametropien, which can differ about the exact measure of pi ù, persistence and potential side effects. From the thirteenth century, the glasses are used to correct the view difficult.
Refractive began at the beginning of the Lambulatorio of the 20th century. The first clinical studies on surgical methods sullindagine of the cornea began in the 1930s with experiments on radi. Up to sixteen oriented radially or star-shaped cut into the surface of the cornea should flatten them with destabilisation, and increase its radius of curvature to correct Kurzsichtigkeiten. However, this procedure has encountered complications from scarring of the cornea. Only in 1978, the radial Keratotomy è been sighted people always pi ù and applied mainly in the USSR and in the United States with initial successes.
When you open the door to the radi. Initially impressive successes were put into perspective by the so-called studio PERK in the United States. There ò shown in between the other cos ì as a significant decline in the medium term a nelleffetto operating prevedibilit ì cos à difficult and has ensured that the radial Keratotomy loses its significance. Rather than face a weakening of the cornea with direct cuts deep, Spaniard Jose Iganacio Barraquer that followed the decline by two-dimensional tissue removal of corneal interior from 1963 (Keratomileusis). Stephen Trokel and others.
1983 first described the method of correcting refractive excimer laser with a.
in 1987, by Theo Seiler allospedale Department à Department à free Berlin with photorefractive Keratectomy (PRK), this procedure è was followed for the first time in humans. In the 1990s, the PRK pi ù è been developed further to LASEK.
in 1989, the first Keratomileusis was combined with the Excimerlaserverfahren and described by Pallikaris and other. how laser-in-situ-Keratomileusis (LASIK). This laser procedure today used primarily and largely supplanted other m é all such as radial Keratotomy.
