Abstract

g Ved fremgangsmåten til fotoablasjon på comea (24) med en laserstråle (21), som det blir foretatt. mange delablasjonsforløp med som følger etter hverandre, blir før hvert ablasjonsforløp tykkelsen på cornea bestemt med en måleinnretning som arbeider sammen med et Michelson-interferometer.Måleinnretningen fører under anvendelse av de registrerte tykkelsesverdiene laserstrålen styrt over cornea med passende intensitetsverdier innstilt av denne, slik at under overholdelse av en forhåndsangitt comeaprofil blir corneatykkelsen ikke mindre enn en forhåndsangitt corneatykkelse. Måleinnretningen arbeider med et Michelson-interferometer med en sentrumsbølgelengde for målestrålingskilden i området fra 1310 nm og en monomode-Faser for denne bølgelengden i referansearmen, slik at den optiske veilengden i luft i målearmen er fritt
