Transmission of 308 nm Excimer Laser Radiation for Ophthalmic Microsurgery — Medical, Technical and Safety Aspects - Übertragung gepulster 308 nm Excimer-Laser-Strahlung für mikrochirurgische Anwendungen in der Augenheilkunde - medizinische, technische und Sicherheitsaspekte

Abstract

A surgical system using 308 nm excimer laser radiation transmitted by quartz fibers is described. In-vitro surgery has been performed on the cornea, in the anterior chamber angle, on the lens and in the vitreous with a special application tip for each procedure. Possible damage of ocular structures by 308 nm radiation is discussed. In-vitro experiments showed that UV exposure of intraocular structures sensitive to 308 nm radiation can be reduced by appropriate design of the application tips and by the application of UV absorbing drugs.
