OphthalmologyOphthalmology always had a pioneer role in use of lasers (Light Amplification by Stimulated Emission of Radiation). A great variety of lasers have been employed since the first laser appeared within the ophthalmic armamentarium for more than 50 years. The German ophthalmologist Meyer-Schwickerath applied the first laser for photocoagulation in the retina in 1949 (Meyer-Schwickerath in Ber Dtsch Ophthalmol Ges. 55:256–9, 1949). A laser is a special surgical device which emits specific electromagnetic light via stimulated emission. Ophthalmic lasers operate at one specific fixed wavelength, pulse pattern, energy, duration, repetition rate, spot size and causing most of the time thermal effects, but photocoagulation, evaporation and non-thermal effects also important, regarding laser-tissue interaction.
