Zusammenfassung
Ein Keratokonus führt zu einer progressiven Vorwölbung und Verdünnung der
Hornhaut. Um dies aufzuhalten, kann ein Crosslinking durchgeführt werden. Dabei
ist eine Behandlung nach dem „Dresdener Protokoll“ eine effektive und sichere
Behandlungsmöglichkeit, aber auch zahlreiche neue Anwendungsprotokolle
(akzeleriertes Crosslinking, transepitheliales Crosslinking) und sogar weitere
Indikationen (refraktive Eingriffe, infektiöse Keratitis) wurden in den letzten
Jahren veröffentlicht.
Abstract
Keratoconus leads to a progressive protrusion and thinning of the cornea. In
order to stop this, corneal crosslinking can be performed if the progression of
the disease is proven. Crosslinking according to the “Dresden protocol” includes
abrasion of the corneal epithelium, application of riboflavin eye drops and
irradiation with UV-A light of an intensity of 3 mW/cm² for 30 minutes. The
efficacy has been shown in several prospective randomized studies. One of the
more recent developments is accelerated crosslinking, which allows a shorter
irradiation time. On the other hand, the possibility of transepithelial
crosslinking was presented, which does not require an abrasion of the cornea.
This should reduce the occurrence of postoperative pain. The range of
indications has also been expanded. Corneal crosslinking is used for post-LASIK
keratectasia as well. It is also being considered for use in infectious
keratitis. Topographically controlled crosslinking can likewise be used to try
to positively influence the refractive power of the cornea. The risks of
crosslinking include the occurrence of pain, haze or scarring, endothelial cell
damage and, rarely, the occurrence of keratitis.
