Derzeitiger Stand der refraktiven Chirurgie an Hornhaut und Linse

Refractive surgery includes all procedures which are primarily targeted at changing the refractive power of the eye. Currently laser-assisted in situ keratomileusis (LASIK) is indicated to correct myopia of up to ??8 D, hyperopia up to +?3 D and astigmatism up to 5 D. Photorefractive keratectomy (PRK) and laser epithelial keratomileusis (LASEK) are primarily recommended for myopia up to ??6 D and for greater refractive errors, phakic intraocular lenses (IOL) are the first choice (myopia greater than ??6 D and hyperopia greater than +?3 D). If presbyopia is present in addition to the high refractive error, refractive lens exchange is another alternative.
