●Kodi katarakitala ndi chiyani?
Diso lili ngati kamera yomwe lenzi imagwira ntchito ngati lenzi ya kamera m'diso. Likakhala laling'ono, lenziyo imakhala yowonekera bwino, yotanuka komanso yosunthika. Chifukwa chake, zinthu zakutali ndi zapafupi zimatha kuwoneka bwino.
Ndi ukalamba, pamene zifukwa zosiyanasiyana zimayambitsa kusintha kwa kutseguka kwa mandala ndi matenda a kagayidwe kachakudya m'thupi, mandala amakhala ndi mavuto a protein denaturation, edema ndi epithelial hyperplasia. Pakadali pano, mandala omwe kale anali oyera ngati jelly amakhala opanda kanthu, makamaka ndi cataract.
Kaya kuonekera kwa lenzi ndi kwakukulu kapena kakang'ono, kumakhudza masomphenya kapena ayi, kungatchedwe kuti cataract.
● Zizindikiro za cataract
Zizindikiro zoyambirira za matenda a cataract nthawi zambiri sizimaonekera, koma ndi maso osawoneka bwino pang'ono. Odwala angaganize molakwika kuti ndi presbyopia kapena kutopa kwa maso, zomwe zimawavuta kuzindikira. Pambuyo pa metaphase, kutseguka kwa lenzi ya wodwalayo ndi kuchuluka kwa maso osawoneka bwino zimawonjezeka, ndipo amatha kukhala ndi malingaliro osazolowereka monga double strabismus, myopia ndi glare.
Zizindikiro zazikulu za cataract ndi izi:
1. Kulephera Kuona
Kusawoneka bwino kozungulira lenzi sikungakhudze masomphenya; komabe kusakhala bwino kwa gawo lapakati, ngakhale ngati chowoneracho chili chaching'ono kwambiri, kumakhudza kwambiri masomphenya, zomwe zimapangitsa kuti kusawona bwino komanso magwiridwe antchito a masomphenya azichepa. Lenzi ikakhala ndi mitambo yambiri, masomphenya amatha kuchepetsedwa kukhala kuwala kapena khungu.
2. Kuchepetsa kukhudzidwa kwa kusiyana kwa zinthu
M'moyo watsiku ndi tsiku, diso la munthu limafunika kusiyanitsa zinthu zomwe zili ndi malire omveka bwino komanso zinthu zomwe zili ndi malire obisika. Mtundu womaliza wa kusinthika umatchedwa kusinthasintha kwa kuwala. Odwala matenda a cataract sangamve ngati akuona bwino, koma kusinthasintha kwa kuwala kumachepa kwambiri. Zinthu zooneka zimaoneka ngati mitambo komanso zobisika, zomwe zimayambitsa kusintha kwa kuwala.

3. Sinthani ndi Mtundu wa Zinthu
Lenzi yamtambo ya wodwala matenda a katarakitala imayamwa kuwala kwabuluu kwambiri, zomwe zimapangitsa kuti maso asazindikire mitundu. Kusintha kwa mtundu wa nucleus ya lenzi kumakhudzanso mawonekedwe amitundu, zomwe zimapangitsa kuti mitundu isamawoneke bwino (makamaka buluu ndi wobiriwira) masana. Choncho odwala matenda a katarakitala amaona chithunzi chosiyana ndi cha anthu wamba.

●Kodi mungadziteteze bwanji ku matenda a cataract ndi kuwachiza?
Matenda a cataract ndi matenda ofala komanso omwe amapezeka kawirikawiri m'madokotala a maso. Chithandizo chachikulu cha matenda a cataract ndi opaleshoni.
Odwala matenda a maso okalamba omwe ali ndi vuto la maso okalamba sakhala ndi mphamvu yaikulu pa moyo wa masomphenya a wodwalayo, nthawi zambiri chithandizocho sichifunika. Amatha kuwongolera kuchuluka kwa kupita patsogolo kwa maso kudzera mu mankhwala a maso, ndipo odwala omwe ali ndi kusintha kwa refractive ayenera kuvala magalasi oyenera kuti awongolere masomphenya.
Ngati matenda a cataract akuipiraipira ndipo kusawona bwino kumakhudza kwambiri moyo watsiku ndi tsiku, ndikofunikira kuchitidwa opaleshoni. Akatswiri amanena kuti masomphenya ochitidwa opaleshoni amakhala osakhazikika pakatha mwezi umodzi. Nthawi zambiri odwala amafunika kuyezetsa maso miyezi itatu pambuyo pa opaleshoni. Ngati kuli kofunikira, valani magalasi awiri (myopia kapena magalasi owerengera) kuti musinthe masomphenya akutali kapena apafupi, kuti muwone bwino.
