Ho: YAG - Uburyo bwiza bwo kubyara 2.1-μm Laser

Laser thermokeratoplasty (LTK) yateye imbere byihuse mumyaka yashize.Ihame shingiro nugukoresha ingaruka zifotora ya laser kugirango fibre ya kolagen ikikije cornea igabanuke kandi kugabanuka hagati ya cornea guhinduka kurtose, kugirango ugere ku ntego yo gukosora hyperopiya na astigmatism ya hyperopique.Lazeri ya Holmium (Ho: YAG laser) ifatwa nkigikoresho cyiza kuri LTK.Uburebure bwa Ho: YAG laser ni 2.06μm, ikaba ari ya lazeri yo hagati.Irashobora kwinjizwa neza nuduce twa corneal, kandi ubuhehere bwa corneal burashobora gushyuha kandi fibre ya kolagen irashobora kugabanuka.Nyuma yo gufotora, diameter ya corneal surface coagulation zone igera kuri 700μm, naho ubujyakuzimu ni 450μm, ni intera itekanye gusa na endotelium ya corneal.Kuva Seiler n'abandi..Ho: YAG laser LTK yakoreshejwe mubikorwa byubuvuzi.Uburyo busa bwo gukosora hyperopiya harimo radiyo keratoplasty na excimer laser PRK.Ugereranije na keratoplasti ya radial, Ho: YAG isa nkaho ihanura LTK kandi ntibisaba kwinjiza probe muri cornea kandi ntibitera na corneal tissue necrosis mukarere ka thermocoagulation.Excimer laser hyperopic PRK isiga gusa hagati ya corneal hagati ya 2-3mm nta gukuraho, ibyo bikaba bishobora gutuma uhuma amaso nijoro kuruta Ho: YAG LTK isiga hagati ya corneal hagati ya 5-6mm.Ho: YAG Ho3 + ion zashyizwe mumashanyarazi. kristu yerekanye imiyoboro 14 ya interineti ihuza abantu benshi, ikora muburyo bwigihe gito kuva CW kugeza gufunga uburyo.Ho: YAG isanzwe ikoreshwa nkuburyo bunoze bwo kubyara imyuka ya lazeri 2,1-μm iva mu nzibacyuho ya 5I7- 5I8, kubisabwa nka laser remote sensing, kubaga kwa muganga, no kuvoma Mid-IR OPO kugirango bigere kuri 3-5micron.Sisitemu ya pompe ya diode itaziguye na Tm: Sisitemu ya pompe ya fibre Laser [4] yerekanye imikorere ya hi hahanamye, bamwe begera imipaka.
