Qhov muag Microsurgery: laser kho

Microsurgery - phais seem, uas tseem ua hauj lwm nrog phais nyob rau hauv heev me me scale. Khiav hauj lwm ntawm no zoo yuav tsum tau tshwj xeeb precision cov khoom thiab siab kev txawj thiab ntau npaum li cas kev phais. Thaum lub sij hawm txoj kev phais siv tej yam me me phais seev thiab phais rub kom pom loj uas muaj tseeb thiab kev daws teeb meem.

Ob peb cov khej Microsurgery: Microsurgery txhuam, microsurgery ntawm lub pob ntseg thiab qhov muag microsurgery. Peb tsis txhob peb paub mus rau yav tas kev taw qhia.

Tej zaum qhov zoo tshaj plaws txoj kev uas yuav los pom laser phais, uas yog tam sim no nqa tawm nyob rau hauv ntau tshaj li 50 lub teb chaws nyob ib ncig ntawm lub ntiaj teb no, es ua lub xub ntiag mus tsheej lab ntawm cov neeg. Qhov no hom ntawm kev phais muaj ib tug xov tooj ntawm zoo:

1. Lub laser muab ib tug ntau ntau yog tshaj lub feem ntau txawj kws phais neeg txhais tes. Ua hauj lwm rau ib tug ntshiab computer kev pab cuam, laser tshuab tso uas tsis ua tsis txhaum.

2. Nyob rau hauv xyoo tsis ntev los, ua hauj lwm tej yam tau pauv los ntawm lub cheeb tsam nyob ze tus kho qhov muag qhov chaw ntawm lub qhov muag nyob rau hauv qhov chaw rau nws tus kheej.

3. Cov rov qab khiav hauj lwm ntawm lub laser txoj kev yeej tseem zoo tsis mob.

4. Duration ntawm lub lag luam yog ib tug teeb meem ntawm vib nas this.

Ib tug neeg mob nrog myopia los yog hyperopia nyob rau hauv lub tsev kho mob qhov muag Microsurgery feem ntau ua rau ib tug xaiv ntawm ob hom ntawm kev ua hauj lwm: PRK thiab LASIK. Lub essence ntawm ob haujlwm yog txo mus rau lub evaporation ntawm cov khaubncaws sab nraud povtseg ntawm cov cornea hloov nws refractive lub hwj chim. Txawm li cas los, qhov txawv nyob rau hauv lub thov yees loj loj.

PRK (los yog lus Askiv PRK.) - ib tug tsiaj ntawv ntawm sophisticated kho mob lub sij hawm "Photorefractive Keratectomy". Qhov no hom ntawm laser pom kev kho tau luam tawm ntau tshaj 20 xyoo dhau los thiab tau txij li thaum lawm siv tau ntse nyob rau hauv cov kev kho mob ntawm nearsightedness, farsightedness thiab astigmatism. Nyob rau hauv PRK corneal nto rau cov kev kho mob siv ib tug tshwj xeeb excimer laser uas cov epithelium puas - nws tej yam ntuj tso kev tiv thaiv txheej. Qhov kawg ntawm kev phais, tus neeg mob feem ntau yog kev ib co mob thiab tsis xis nyob rau hauv lub ua qhov muag. Lwm yam yuav tshwm lag luam cov sij hawm poob photophobia thiab ntau tearing. Yuav kom restore pom tseeb tseeb yuav siv sij hawm li 3 mus rau 7 hnub. Thaum zoo li no lub zeem muag yog tag nrho stabilized tom qab 3-4 lub hlis ntawm hnub tim uas lub lag luam. Feem ntau, thawj zov me nyuam tau rau ib lub qhov muag, thiab tom qab 7-14 hnub - nyob rau lwm yam. Kom tsis txhob ntog mus rau hauv lub ua qhov muag plua tshauv hais los yog av, thiab nws tsis lim lub qhov muag "ntaub" ntaub - hnav khaub ncaws. Thaum lub sij hawm rov qab lub sij hawm li nram no raws li lub qhov muag dauv mus muab zoo zoo txheej txheem.

KGF txoj kev tau proven zoo rau kev kho mob ntawm astigmatism rau -3, -6 rau myopia thiab hyperopia rau +3 diopters. Qhov no hom ntawm kev phais kev pab favorably nrog lwm txoj kev uas yuav tsum muaj ntaub ntawv mus rau ib tug neeg mob muaj yog ib tug me me thickness ntawm lub cornea, uas muaj peev xwm pab tau raws li ib tug contraindication rau LASIK phais.

Tsis zoo li KGF LASIK phais (Engl. LASIK) tsis muaj feem xyuam rau qhov chaw khaubncaws sab nraud povtseg ntawm cov cornea, uas eliminates mob thiab ua rau ceev ceev post-operative rov qab lub sij hawm. Lub lag luam yog ua nyob rau hauv ob ua sawv. Nyob rau hauv thawj mus rau lub cornea nyob rau hauv lub kho qhov muag qhov chaw ntawm lub qhov muag siv ib tug microkeratome (tej yam me me tej cuab tam) txiav nrov plig plawg, tab sis tsis tau kiag li, tawm hauv ib tug "txhais ceg." Nyob rau lub 2nd theem, qhov nrov plig plawg yog daim ntau quav tso nyob rau hauv cov kev taw qhia rau cov laser beam los muab unimpeded nkag tau mus rau hauv nruab nrab khaubncaws sab nraud povtseg ntawm cov cornea. Tom qab evaporation ntawm qhov nrov plig plawg khaubncaws sab nraud povtseg ntawm ib tug predetermined thickness yog siv rau hauv qhov chaw.

LASIK technology tso cai rau koj khiav lag luam ob lub qhov muag nyob rau hauv ib hnub thiab txaus siab rau tus ntse thiab meej lub zeem muag nyob rau hauv 2-3 xuab moos tom qab lub lag luam.
