Ixesha elizayo kwiCataract Surgery?
Izazinzulu zaseCalifornia ziphanda i-steroid ngokwemvelo ebizwa ngokuba yi-lanosterol engasetyenziswa olunye usuku ukunyanga i- cataract . Kungenzeka ukuba olunye usuku lusetyenzise i-lanosterol ngendlela yohlahlo lwamehlo e-topical ukunciphisa uphuhliso lwe-cataract. Iindleko zeranosterol ezihlawulela ziya kuba ziphantsi kakhulu kuneendleko zokuhlinzwa kwe-cataract. Izigidi zeedola zichithelwa zizigulane, iinkampani zomshuwalense kunye nokunakekelwa kwempilo karhulumente ukuhlawula i-ophthalmologists kunye nokulawula ulawulo lwama-optometrists ukususa i-cataract.
I-Lanosterol iliso lehla liyakwazi ukuba yindlela ekhuselekileyo, engeyiyo ingavumelekanga ekusebenziseni i-cataract kwizigulane ezineendlela ezidityanisiweyo ze-cataracts
Ziyintoni iCataracts?
I-cataract i-clouding okanye ilahleko yokukhanya kwi- lens yemvelo kweso. I-lens yomntu yenziwe ngamaphrotheni e-crystalline. Xa usemncinci kwaye unempilo, ezi proteins zisebenza ukugcina ilensi icacile. I-Cataracts ithuthuka kuba njengoko sibudala, ezi proteins ziphazamiseka, zidibanise kunye kwaye ziphule. I-Cataract ithintela umbono kwaye ibangela imifanekiso ukuba ibonakale ifufayo, inobunzima okanye inqabileyo efanayo ukujonga ngefestile yefrigi. I-Cataract iyona nto ibangela ukuphosakeka phakathi kwabantu abadala kunama-55. Uphuhliso oluncinci lwe-cataract luyenzeka njengenxalenye yenkqubo yokuguga ngokuqhelekileyo kwaye akunqabile ukufumana ukungabikho ngokupheleleyo kwe-cataract kubantu abadala.
I-Cataract ingenzeka ngakumbi okanye ingaphumi kwantoni. I-cataracts ingabangelwa ukuthatha amayeza athile, afana ne- prednisone steroids .

Eyedrops kwiCataract Treatment
Iingcali zenzululwazi zithole i-lanosterol's cataract ukunciphisa amandla ngokufunda abantwana ababini abanesimo esizuze ilifa apho bahlakulela khona i-cataracts beselula. La bantwana babelana ngokuguquka kwemfuyo apho imizimba yabo inqande ukuveliswa kwe-lanosterol. Okuthakazelisayo kukuba abazali babo bebengenalo utshintsho kwaye abazange bahlakulele. Izazinzulu zenza ukuba i-lanosterol isebenze ukugcina ilensi yomntu icacile ngokuyeka ukuphazamiseka nokuqhafaza kwamaprotheni aqhelekileyo kwilensi.
Usosayensi waqala ukuvavanya imfundiso yabo kwiseli yoluntu lensile. Izifundo zibonise ukuba xa i-lanosterol isetyenziswe kwiiseli, iiprotheni ze-lens zayeka ukumisa kunye nokukhanya. Emva koko, bafundela onogwaja abanengxaki yokuguga. Emva kokulawula i-lanosterol kwiintsuku ezintandathu, i-85% yemvundla yayinciphisa ngokukhawuleza kobunzima be-cataract.
