Izinqubo zokusebenza
Ukuzama ukuthuthukisa umbono ngokusebenzisa ukungenelela kokuhlinzwa kwakusasekuphakathi kwekhulu lama-20. Kodwa manje lezi zindlela ziphephile kakhulu futhi zingenabuhlungu. Uhlelo oluyisisekelo lomsebenzi wukuthi ufakwa embhedeni, ubeke ubuhlungu obubulalayo emehlweni akho bese ufaka i-expander kumajwabu amehlo akho ukuze avule ngesikhathi sokusebenza konke. Ukuzizwa ngesikhathi sokulungiswa kufana nokuhlolwa kwesilonda. Uzozwa nje umsindo womsebenzi we-laser bese ubona ukukhanya okukhulu. Uzodinga ukugxila endaweni eluhlaza bese ugcina ukungahambi kahle okuphelele phakathi nokusebenza konke. Ngemuva kokuhlinzwa, udokotela uzokutshela zonke izincomo okudingeka uzilandele. Kunezinhlobo ezintathu eziyisisekelo zokusebenza kwamehlo:
Indlela ye-PRK noma ye-PRK , okusho ngokoqobo ukuthi i-keratectomy ye-photorefractive. Le ndlela isekelwe eqinisweni lokuthi udokotela ophethe i-laser usebenza engxenyeni yangaphandle ye-cornea. Le ndlela ayithinti ukujula kweso. Ngemuva kokusebenza, i-lens ifakwa iso, eliyivikela. Kungakapheli izinsuku ezine, ungqimba lwamangqamuzana afaka ebusweni bamehlo, okuthiwa i-epithelium ubuyiselwe futhi i-lens isusiwe. Phakathi nalesi sikhathi, isiguli singase sibe nomuzwa wokuthi kukhona "ihlumela leso", angase abe nokukhala futhi ukwesaba ukukhanya. Lokhu kusebenza kuhle ngoba akukho ukungenelela okuhlinzekwayo, kanti isikhathi sokusebenza sifushane.
Inqubo ye-LASIC ihlanganisa kokubili ukungenelela kokuhlinzwa kanye ne-laser. Usebenzisa idivayisi ekhethekile ebizwa ngokuthi i-microkeratome, udokotela ukhala ungqimba olungaphezulu lwe-cornea futhi ugoqa ukugoqa okuphumela. Bese udala isimo esisha se-cornea nge-laser ngendlela ye-lens yemvelo ngokukhuphuka kwengxenye ye-cornea. Ngemuva kwalokho, ukukhanya okudlula i-cornea kuzokhishwa ngenye indlela, futhi isithombe sizocaca. Ngemuva kokusebenza, akudingeki iziqu, njengoba i-cornea e-incised, efakwe endaweni, izokhula ngokushesha.
Inqubo ye-SUPER LASIK yukuthi ngaphambi kokuba kusetshenzwe imephu yezithombe ezisobala, futhi ngesisekelo salo uhlelo lokusebenza. Khona-ke ukusebenza kuhamba kuzo zonke izinyathelo zokulungiswa okujwayelekile kwe-LASIC. Yiqiniso, lo msebenzi ubiza kakhulu kunezinye, ngoba zonke izici ezincane kakhulu zeso zicatshangelwa lapha.
Ukuqhathaniswa kwe-laser correction
Ngokungangabazeki, lokhu kusebenza kuyingozi, futhi ngaphambi kokuxazululwa, kudingekile ukuhlolwa okuphelele kokuhlolisisa. Kubalulekile ukwazi ukuthi ukulungiswa kwe-laser kunezinamba eziningi zokuphikisana:
- ubudala kuya eminyakeni engu-18;
- izifo ezizimele - ukuzivivinya umzimba;
- izifo ezithinta inqubo yokuphulukisa;
- ubukhulu be-cornea kufanele bube ngu-450 (440) μm noma ngaphezulu;
- i-glaucoma, okungukuthi ukunyuka kwe-intraocular;
- i-keratoconus, lapho i-cornea inomzimba omncane kakhulu futhi ifana nomumo;
- isebenze imishini yokubuyisela;
- isifo sikashukela;
- ukukhulelwa;
- izifo zamehlo ezingapheli;
- ukuphazamiseka kwengqondo nabanye.
Ukunquma ngesinyathelo esinjalo akulula, futhi kubalulekile ukuqonda ukuthi, ngokuyinhloko, ukukhubazeka okubukwayo kwenzeka endaweni yezakhi zofuzo, okungukuthi, kudluliselwa kubazali. Ukulungisa umbono kulokhu ngeke kube khona. Akekho udokotela onganikeza isiqiniseko esingu-100% ukuthi umbono ngeke uphumele ngemva kweminyaka engu-15. Umkhuba womhlaba ubonisa ukuthi ukuwohloka ngemuva kokusebenza kwenzeka ngo-4-12%. Phakathi kwezizathu kungase kube ukulungiswa ngaphansi kwezinkinga, izinkinga zokuphulukisa, umzamo wokuqeda ngesikhathi sokuphambuka okukhulu okuvela esimweni esivamile.
Uma usenqume ngalesi sinyathelo, khona-ke xhumana nezikhungo ezikhethekile kuphela nezidokotela abaqeqeshiwe, nemishini yakamuva. Ngaphambi kokusebenza, uzochitha isikhathi esiningi ekuxilongweni. Okokuqala udinga ukubona udokotela - optometism. Ungumuntu osebenza ngokukhethekile emishini, ukuhlolwa kweso futhi unikeza umuthi wokwelapha olandelayo. Uzokuqondisa ku-ophthalmologist. Uma ukhetha umtholampilo, qaphela ngokwengeziwe uma ufunda imigomo yesivumelwano. Uma kunenkinga emva kokuhlinzwa, umtholampilo wekhwalithi uzokuqeda mahhala, uzokuhlola isikhathi eside uma kudingeka. Kubalulekile ukucabanga ngezinkokhelo ezifihliwe, ukuya emtholampilo, lapho ukusebenza kungabizi kakhulu kunezinye. Uma unokuphambuka okuningi ngokweqile, ukusebenza kwenziwa ezinyathelweni eziningana. Ngesinye isikhathi ngezingu-5 ngeke uthole iyunithi.
Imiphumela emibi yokulungiswa kombono we-laser
Ngakho, ukulungiswa kwe-laser yombono kuyisinyathelo esinokwethenjelwa. Emitholampilo yaseMelika bakhipha amabhulogi akhuluma ngokuphepha okuphelele kanye nokungabikho kwemiphumela emibi emva kokusebenza okunjalo. Kodwa ngokuhamba kwesikhathi, iziguli zangaphambili zaqala ukuza kubo ngezikhalazo ezinokubheka kabili emehlweni abo, imibuthano kanye nama-asterisks avela phambi kwamehlo abo. Ngokuhamba kwesikhathi, imitholampilo engabhalisi ulwazi olugcwele mayelana nemiphumela engaba khona iyobekwa ngaphansi kwezijeziso zobugebengu. Manje lokhu kungumlingisi wokuqapha.
Yonke imiphumela ayizange ifundwe okwamanje, futhi lokhu kubangela ukukhathazeka. Omunye wemiphumela emibi ingase ibe yi-conjunctivitis, amasosha okubuyisela, ukulimaza, ukukhubazeka kwe-epithelial. Ukuphumelela kokusebenza kuxhomeke ekuhlangenwe nakho kukadokotela, iziqu zakhe, ekuxilongweni okufanele futhi, ekugcineni, ngezici zenyama. Wonke umuntu uhlukile, ukuthi umzimba wakho uphendukela kanjani ekungeneni kwe-laser - akucacile.
Ngakho izigidi zabantu zihlala nezibuko nama-lens. Abaphazamisi nabo nhlobo. Ukulungiswa, okuyiqiniso, kuyoduduzeka, kodwa ngubani othi ngeke ikunikeze izinkinga eziningi?
