Kangangeminyaka emininzi ngoku, abantu abanengxaki yokubona baye bakwazi ukubhenela kuyo utyando refractive ukulungisa kubo nokuphelisa iiglasi okanye contact lens ngonaphakade. Utyando lwe-refractive luquka iqela longenelelo okanye ubuchule botyando apho iingxaki ezithile ezibangela ukuguqulwa kombono zilungiswe okanye zipheliswe. Ngokomzekelo, i-myopia, i-astigmatism, i-hyperopia kunye nanamhlanje i-presbyopia nayo inokulungiswa.
Uncedo olukhulu kubantu abafuna, abanqwenela okanye abafuna ukuyeka ukunxiba iindondo, nokuba kungenxa yobungcali, ezemidlalo okanye nje izizathu zobuhle.. Ngenxa yokuba iiglasi ziyinto enhle kakhulu, i-accessory eyonwabisayo eyongeza ubuntu ebusweni, kodwa kuthi sonke ekufuneka sinxibe imihla ngemihla ayiyonto ngaphandle kokukhumbuza ukuba ngaphandle kwabo, silahlekile.
utyando refractive
Kukho iintlobo ezahlukeneyo zotyando lokuphinda lulungiswe iingxaki zombono. Kwimeko nganye, iya kuba yingcali emisela ukuba yeyiphi eyona ifanelekileyo kwaye ngaphezulu kobuchule obunye bunokusetyenziswa kwangaxeshanye kumntu omnye. Ngezantsi siza kukuxelela zeziphi iintlobo zotyando refractive, xa zisetyenziswa kunye nendlela ubuchule benziwa ngayo.
Utyando lweLaser refractive, LASIK okanye PKR
Xa i-laser isetyenziselwa ukulungisa ukuguqulwa kwamehlo okubangela iingxaki zombono, into echaphazelekayo kukuguqula imilo ye-cornea ukwenzela ukuba i-diopters ekhusela umbono ochanekileyo ingalungiswa. Ubume bunokwahluka ngokuxhomekeke kuthweso-zidanga Kwisigulane ngasinye, umzekelo, xa kusetyenziswe ubuchule be-LASIK, ukungenelela okulandelayo kwenziwa.
- Ukulungisa i-myopia: Yintoni eyenziwayo ifake i-curvature nge-laser, ngoko ukukhanya kugxininise ngokuchanekileyo kwi-cornea.
- Kwimeko ihyperopia: Kule meko imiphetho ye-cornea ibunjwe ukwenza i-curvature.
- Nge-astigmatism, into eyenziwayo ilula indawo kunye ne-curve enkulu ye-cornea ukuyishiya njengento efanayo ngokusemandleni.
Kwimeko ebizwa ngokuba yi-PKR yotyando oluhlaziyiweyo, ubuchule Kuyafana kodwa kudla ngokucaphukisa ngakumbi kumguli. Yayibubuchule bokuqala obabusetyenziswa ukulungisa iingxaki zombono, ngoko namhlanje iphuculwe kakhulu kwaye yiyo loo nto ingasasetyenziswa rhoqo.
I-lens ye-intraocular nayo ingasetyenziswa
Kwezinye iimeko, endaweni yokusebenzisa i-laser ukuguqula i-cornea kunye nokuphucula umbono, i-lens inokufakwa okanye i-lens isuswe, kuxhomekeke kwiimfuno zesigulane ngasinye. Lo bubuchule obudla ngokusetyenziswa xa isigulane sine-diopters ezininzi kunokuba zivunyelwe ukwenza utyando lwe-laser refractive. Kwimeko yokufakelwa kwe-lens, i-crystalline lens igcinwa. Kwezinye iimeko, i-lens iyasuswa kwaye i-lens aphakic ifakwe, eyona ndlela isetyenziselwa ukuphelisa i-cataract.
Njani ukwazi ukuba ndingatyandwa
Ukukwazi ukwenza utyando lokuphinda uhlaziye kwimeko yokufuna ukulungisa iziphene zombono, njenge-myopia, i-astigmatism okanye i-hyperopia, Isigulana kufuneka sihlangabezane nemilinganiselo ethile. Kwelinye icala, uthweso-zidanga kufuneka luzinzile ubuncinci iminyaka emibini. Ezinye iiparamitha zokhuseleko nazo ziyavavanywa kwaye kufuneka zivavanywe yingcali kwimeko nganye.
Eyona ndlela ingcono yokusombulula onke amathandabuzo kukuya kubona ingcali enokuthi ikuhlole kwaye ikuchazele izinto ozikhethayo. Kuba zininzi iiparameters ezivavanywayo kwimeko nganye, iimfuno zesigulane ngasinye kunye nethuba lokufumana iziphumo ezifunwayo zinokuhluka kwimeko nganye. Ngaphandle koko, Nangona ilutyando olukhuseleke kakhulu, alukhululekanga kwiziphumo ebezingalindelekanga. nayo kufuneka ixatyiswe. Hlala uzibeke ezandleni ezilungileyo, lungisa onke amathandabuzo. Shiya ixesha apho unokubonakalisa kwaye wenze isigqibo sokuba nini, njani kwaye nabani na ofuna ukwenza utyando ukuze uphelise iingxaki zombono ngonaphakade.
