Ngobudala, lapho izizathu ezahlukahlukene zibangela ukuguqulwa kwe-lens shintsha kanye nokuphazamiseka kwe-metabolic, ilensi inezinkinga ze-protein denaturation, i-edema ne-epithelial hyperplasia. Okwamanje, i-lens esetshenziselwa ukucaca njengoJelly izoba turmid opaque, okungukuthi nge-cataract.
Akunandaba ukuthi i-opacity yelensi inkulu noma incane, ithinta umbono noma cha, ingabizwa ngokuthi i-cataract.
● Izimpawu zeCataract
Izimpawu zokuqala ze-cataract zivame ukungabonakali, kuphela ngombono omfushane ofiphele. Iziguli zingase zingayibheka njengephutha njenge-Presbyopia noma ukukhathala kwamehlo, kalula ukuphuthelwa ukuxilongwa. Ngemuva kwesifaniso, i-opacity yelensi yesiguli kanye nezinga lombono okufiphele zikhula, futhi zingaba nemizwa ethile engajwayelekile njenge-strabismus ephindwe kabili, i-myopia ne-glare.
Izimpawu eziphambili ze-cataract zimi ngalendlela elandelayo:
1. Umbono okhubazekile
I-Opacity ezungeze ilensi ayikwazi ukuthinta umbono; Kodwa-ke i-opacity engxenyeni ephakathi nendawo, noma ngabe ubukhulu buncane kakhulu, buzothinta kakhulu umbono, obangela umbono wombono ofiphele nokusebenza okubukwayo. Lapho i-lens inamafu kakhulu, umbono ungancishiswa ukuze ubone umbono noma ubumpumputhe.
2. Ukwehliswa kokuzwela kokuhluka
Empilweni yansuku zonke, iso lomuntu lidinga ukuhlukanisa izinto ngemingcele ecacile kanye nezinto ezinemingcele eqinile. Uhlobo lokugcina lokuxazululwa lubizwa ngokuthi ukuzwela okuhlukile. Iziguli ze-Cataract zingezwa ukuwohloka okusobala okusobala, kepha ukuzwela kokuhluka kuncishiswa kakhulu. Izinto ezibukwayo zizovela zinamafu futhi zibe nzima, zibangele into ye-halo.

3. Shintsha ngomqondo wombala
Ilensi enamafu yesiguli se-cataract ithatha ukukhanya okuluhlaza okwesibhakabhaka, okwenza iso lizwele kancane ngemibala. Izinguquko kumbala we-nucleus welensi futhi zithinta umbono wombala, ngokulahleka kokucaca imibala (ikakhulukazi ama-blues kanye nemifino) phakathi nosuku.

I-Cataract yisifo esivamile futhi esivame ukwenzeka ku-ophthalmology. Ukwelashwa okuyinhloko kweCataract kungukuhlinzwa.
Iziguli zakuqala ze-Senile Cataract azinamthelela omkhulu empilweni yombono wesiguli, ngokuvamile ukwelashwa akudingekile. Bangakwazi ukulawula isilinganiso senqubekela phambili ngomuthi wamehlo, kanye neziguli ezinezinguquko ezivumayo zidinga ukugqoka izibuko ezifanele ukuthuthukisa umbono.

Ngokuvamile iziguli zidinga ukwenza ukuhlolwa kwe-optometry ezinyangeni ezi-3 ngemuva kokuhlinzwa. Uma kunesidingo, gqoka izingilazi ezimbili (i-myopia noma ingilazi yokufunda) ukulungisa umbono omude noma oseduze, ukuze uzuze umphumela obonakalayo ongcono.
