    1. Laserov opercie oka

    2. Oko zkladn zmyslov orgn Oko je najdleitejm zmyslovm orgnom Stelesnuje najvznamnej zo vetkch zmyslov - zrak. Clovek zskava a 90% informci o vonkajom prostred pomocou zraku

    3. Stavba oka Oko (oculus) je zloen z: ocnej gule (bulbus oculi) prdavnch orgnov okohybn svaly spojivka slzn apart ocn viecko

    12. Fyziklny princp laserov Laser /Light Amplificiation Stimulated Emision Radiation/ je zdroj lca koherentnej elektromagnetickej energie svysokou intenzitou iarenia. Vlastnost laserovho svetla: energia a vkon vzkom vyarovacom zvzku monochromatickost mal rozbiehavost/divergencia/ laserovho svetla, vysok sveteln intenzita

    13. Klasifikcia laserov Podla toho ak laserujce prostredie maj lasery ich delme na: lasery spevnm laserovm prostredm lasery skvapalnm laserovm prostredm lasery splynnm laserovm prostredm Podla vyarovanej vlnovej dlky delme lasery na: infracerven lasery v oblasti viditelnho svetla ultrafialov rntgenov Podla pouitia meme lasery rozdelit na: vskumn meracie lekrske technologick energetick vojensk

    16. Vyuitie lasera pri opercich oka

    21. spenost a dostupnost korekcnch laserovch metd pre prax pravdepodobnost dosiahnutia optimlneho vsledku je pomerne vysok. Presnost laserovho prstroja je temer absoltna a pred operciami denne kontrolovan. Vsledok zkroku je do urcitej miery ovplyvnen charakterom prestavby rohovkovho tkaniva v obdob hojenia, ktor je velmi individulny a variabiln.
