Ngokuthuthukiswa kwe-cataract, i-cloudiness ivimbela ukukhanya ekugxileni futhi kufinyelele ku-retina, ngezinye izikhathi okuholela ekulahlekelweni kombono enja.

Kunezigaba eziningana ze-cataract ezinjeni. Kodwa-ke, kunzima kakhulu ukunquma ukuthi lesi sifo sizothuthuka futhi size kangakanani.

Abanikazi bezinja bavame ukuqaphela inkinga lapho ungwengwezi lufika esigabeni esingavuthiwe. Lokhu kusho ukuthi isivele ihlanganisa ingxenye ephawulekayo yelensi - kusukela ngaphansi kwesigamu kuya cishe yonke indawo yayo. Kuleli qophelo, inja ngokuvamile iba nokuwohloka kombono, kodwa isengakwazi ukunxephezela kahle ngokumangalisayo. 

Isigaba sangaphambili se-cataract sibizwa ngesigaba sokuqala. Ngalesi sikhathi, i-cataract incane kakhulu futhi ayikwazi ukubonakala ngeso lenyama lomuntu ongeyena uchwepheshe. Isifo esiqhubekayo futhi simboze yonke ingxenye yelensi enempilo ibizwa ngokuthi isiteji esivuthiwe. I-cataract ekhulile kuwo womabili amehlo iholela ekuphuphuthekeni okuphelele.

Kodwa konke akulula kangako: uma amehlo enja eguqubele, lokhu akuhlotshaniswa njalo ne-cataract. Njengoba izinja zikhula, amalensi wamehlo azo aba lukhuni futhi angase abe mpunga obisi. Lolu wushintsho oluvamile oluhlobene neminyaka olubizwa ngokuthi i-nuclear noma i-lenticular sclerosis futhi akuthinti ukubona. Udokotela wezilwane uzokwazi ukuhlukanisa i-nuclear sclerosis kusuka ku-cataract, ngoba naphezu kokufana kwabo, lezi kuseyizifo ezihlukene.

Ukwelashwa kweCataract Ezinjeni

Ulwelwesi lwesikhumba lusanda kuqala ngokuvamile aludingi ukwelashwa, ngoba aluphazamisi ukubona kwenja. Nokho, njengoba ilensi ishintsha inqubekelaphambili, umbono wenja uzowohloka.

Ukwelashwa kokuhlinzwa kolwelwesi ezinjeni kube yimpumelelo amashumi eminyaka ambalwa. Njengoba izilwane ezifuywayo eziningi ezinalesi simo zikwazi ukunxephezela ukulahlekelwa umbono ngokusebenzisa ezinye izinzwa ezinamandla, ukwelashwa kwe-cataract, nakuba kunconywa, akubhekwa njengesibopho.

Udokotela wezilwane cishe uzodlulisela isilwane kudokotela wamehlo wezilwane ogunyazwe yibhodi. Uchwepheshe uzokwenza ukuhlolwa, okubizwa ngokuthi i-electroretinogram, ukuze ahlole isimo sokusebenza kwe-retina yenja, kanye ne-ultrasound yeso ukuze aqiniseke ukuthi i-retina ayihlukani.

I-cataract ezinjeni: ukuhlinzwa

Inqubo ngokwayo iwukuhlinzwa okusheshayo lapho udokotela ohlinzayo enza khona ukusika okuncane ukuze akhiphe ilensi ethintekile. Ngemva kokuhlinzwa, inja kufanele inikezwe imithi enqunywe udokotela futhi ngemva kwesikhashana iyiyise kuchwepheshe ukuze ayohlolwa ngokuqhubekayo. Ezinjeni eziningi, umbono kanye nokuphila kahle okuvamile kubuyiselwa phakathi nezinsuku ezimbalwa.

Uma ukuhlinzwa kungenakwenzeka, kubalulekile ukulawula inkambo yesifo. I-cataract ingaholela ekususweni kwe-lens noma i-glaucoma, kokubili okuzodinga ukungenelela.

Isifo esiwumphumela wesifo sikashukela singagwenywa. Into eyinhloko ukugcina inja ngesisindo esivamile, ukuyinikeza ukudla okulinganiselayo okuqukethe zonke izakhi ezidingekayo, futhi ulandele zonke izincomo zodokotela wezilwane.

Ngeshwa, i-cataract yofuzo ayikwazi ukuvinjelwa. Ngaphambi kokuba uthathe isilwane kumfuyi noma endaweni yokukhosela, udinga ukuthola ukuthi umdlwane unesifo sofuzo. Ungakwazi futhi ukumyisa kudokotela wezilwane ukuze ayohlolwa ekuqaleni kwanoma yikuphi ukuphazamiseka kwamehlo noma izinkinga zokubona. Lokhu kuzogcina amehlo enja yakho enempilo futhi ecacile eminyakeni yawo yegolide.

Bona futhi:

• Kufanele uye kangaki inja yakho kudokotela wezilwane?
• Ingabe inja yakho inezinkinga zokugaya ukudla?
• Kungani inja ingadli?
• Ukuphila kwezinja
