Ukuhlinzwa cataract

Cataract lubonakaliswa turbidity lens, okuholela ukuwohloka okukhulu futhi sizibona ngokucacile. Lokhu kwazicasula esengqondweni iyacaca futhi Ukufiphalisa livela izinto ebonakalayo. Ngokuvamile, lapho cataract iqala umbono double futhi zenza abantu babe ukushintsha izibuko namandla. Iningi le sifo abesifazane.

Izimbangela ngwengwezi zihlukile, kwenzeka ayephuli amandla ayo ayinhloko lens ukulahlekelwa, ukuhlukumezeka, ukuphazamiseka izinqubo umzimba emzimbeni, kanye nesifo sikashukela. Yiqiniso, ngokuvamile kubonakala cataract senile noma senile. Kwakuphakathi nalesi sikhathi uqala ukwandisa kwabantu of lens, kungenxa kakhulu esinamafu. Kodwa lesi sifo kungenzeka kweminyaka eyi-50.

Kukhona cataract zenani elikhulu eziyifa kanye azalwa nako. Kungaba avele ebuntwaneni. Ngokuvamile lesi simanga lihlotshaniswa zokugula lens, okuyinto eyenzeka ngisho ukuthuthukiswa intrauterine umbungu.

ngwengwezi Obungapheli kungaba ngasiphi yobudala. It kuvela kusuka zamakhemikhali noma ukusha ezishisayo, punctures, ukusikeka noma umthelela. Isikhathi esining impela kukhona cataract ngesizathu kokunikezwa kwe-nezindlala endocrine, ezifana ukuthuthukiswa sikashukela. Le ndlela cataract e izingane nentsha. It ngokushesha futhi ngokuvamile kakhulu zamazwe amabili. It libhekene izinguquko sasivumela ekuqaleni lens ngenxa yokwephula ukuvikelwa izinyembezi.

ukuhlinzwa cataract kungenzeka kuphela emva izifundo zokuxilonga usebenzisa keratometry futhi refractometry. Sincumo ke kulinganiswa acuity ezibukwayo futhi ingcindezi intraocular, isimo retina, kanye ukuhlola emkhakheni umbono. Ngemva ekufezeni a zokuxilonga sinquma amandla optical lens yokufakelwa, ukuze abe ukusebenza kungenzeka. Cataract iyelapheka, futhi zonke lezi sivivinyo seluhlololucwaningo baqiniseka kobuhlungu futhi akabubangeli ngokuphazamiseka okukhulu.

Emva uphethwe inikezwa eyohlinzwa ukususa cataract. It kungenziwa ngokusebenzisa phaco ultrasonic. Lokhu ukususwa lens ngu sonication usebenzisa izinzwa epibulbar. Siqukethe ngalolo iso liqala iphathwa nge izinzwa imizuzu engu-20 ngaphambi ukusebenza futhi ngemva kokuba isiguli iyeke uzizwa into kulo izinqubo cataract ukususwa. Ukusebenza ihlala hhayi ngaphezulu imizuzu 12.

kokungenela Steel esiyolandelwa ngesikhathi lezitsha ekhethekile elikuvumela ukuba afeze imisebenzi, ngisho nabantu kahle uhlelo zemisipha. ukuhlinzwa cataract kungenzeka futhi ngosizo laser kanye ultrasound. Ukususwa lens wenziwa ngendlela beztravmaticheskim, okungukuthi nge wokubhoboza ezincane, okuyinto akudingi sutures ngemva kokuhlinzwa.

Izinzuzo main wokusebenza noiseless wukuthi asikho isidingo izinyanga eziyisithupha ukususa ezivuzayo, kakhulu ziyancipha astigmatism nasezinkingeni ezilandela ngemva kokuhlinzwa.

ukuhlinzwa cataract wenziwa kungakhathaliseki nokuvuthwa lens kwaso indawo Kwenziwa ngokushesha futhi ngaphandle kwemiphumela. ukuhlinzwa cataract ngale ndlela kwenza kube nokwenzeka ukuba enze operation uma isifo kuhlangene nezinye, ezifana ukucindezeleka kwangemva kwenhlekelele izinguquko subluxation lens, sokuwohloka ngwengwzi, hemophthalmus, retinopathy sikashukela, futhi khona izifo ezivamile, ezifana komzimba ahlukahlukene, izifo igazi, umdlavuza kanye izifo zezinzwa, isifo sikashukela, isifo senhliziyo nomfutho wegazi ophezulu.

ukuhlinzwa cataract wenziwa nokusebenzisa i-laser kanye isizinda lapho lens sisuswa laser amandla. Kulokhu, phezu kobuso lens labetibambile anemifantu ezimbili perpendicular. I siqala ikhenela ukugqekeza izingcezu ezine. Khona-ke la izingxenye zilandelana ubhujiswe, bese aspirated noma ukuqhuba ukuwasha kanye nezindlu zangasese. Ngemva izinzwa ukwakheka imihubhe imbobo corneal ukujikisa nucleus lens. Lonke operation iphela emva kwemizuzu eyishumi nanhlanu. Lunini harurgicheskoe kokungenela, lolu ngwengwezi zisuswe kalula ngokusebenzisa le imbobo encane, ukuze alizibonanga kuze kube manje umuntu eqala ukubona kahle.

lens Artificial (noma i-IOL) e impahla yayo iyafana lens zemvelo. Nokho, kuyinto onokwethenjelwa futhi kungaba esweni eliyingqayizivele. Okwamanje, umtholampilo has a lot of lens intraocular, kokubili ukukhiqiza ezahlukene angaphandle kanye ezifuywayo, okungase busuka iso ngokusebenzisa imbobo omncane. Okubaluleke kakhulu, ngemva ukwethulwa astigmatism lens siqedwa ngokuphelele, kanye ingozi ukuncipha cataract yesibili. Odokotela abaningi bathambekele baphikisa ngokuthi ngwengwezi beya isuswe sibi kakhulu. Futhi uma isifo sikashukela umuntu, kungaba khona yezinkinga ngenxa ithonya ultrasound kuyi-retina, ngoba kungaholela lamabutho ngwengwzi nokulahlekelwa ephelele umbono. Ngakho-ke, ngaphambi kokuqhuba ukuhlinzwa cataract kumele kuhlolwe ukuze ligweme izinkinga ezingase zivele ngokucophelela.
