●Kodi ng'ala ndi chiyani?
Diso lili ngati kamera yomwe lens imagwira ntchito ngati lens ya kamera m'diso. Akali ang'ono, mandala amawonekera, otanuka komanso owoneka bwino. Zotsatira zake, zinthu zakutali ndi zapafupi zimatha kuwonedwa bwino.
Ndi zaka, pamene zifukwa zosiyanasiyana kuchititsa mandala permeability kusintha ndi kagayidwe kachakudya matenda, mandala ali ndi mavuto a mapuloteni denaturation, edema ndi epithelial hyperplasia. Panthawi imeneyi, mandala ankawoneka bwino ngati odzola amasanduka opaque, monga ng'ala.
Ziribe kanthu kaya kuwala kwa lens ndi kwakukulu kapena kochepa, kumakhudza masomphenya kapena ayi, akhoza kutchedwa cataract.
● Zizindikiro za cataract
Zizindikiro zoyambirira za ng'ala nthawi zambiri sizidziwikiratu, kokha ndi kusawona bwino. Odwala angaganize molakwika ngati presbyopia kapena kutopa kwamaso, kuphonya mosavuta. Pambuyo pa metaphase, kuwala kwa mandala a wodwalayo komanso kuchuluka kwa kusawona bwino kumakulirakulira, ndipo amatha kukhala ndi kumverera kwachilendo monga double strabismus, myopia ndi glare.
Zizindikiro zazikulu za cataract ndi izi:
1. Kusawona bwino
Kuwonekera kozungulira disolo sikungakhudze masomphenya; komabe mawonekedwe apakati, ngakhale kukula kwake kuli kochepa kwambiri, kungakhudze kwambiri masomphenya, zomwe zimapangitsa kuti kusawona bwino ndi kuchepa kwa ntchito. Pamene mandala ali ndi mitambo kwambiri, masomphenya amatha kuchepetsedwa kukhala kuzindikira kopepuka kapena ngakhale khungu.
2. Kuchepetsa kukhudzika kosiyana
M'moyo watsiku ndi tsiku, diso la munthu liyenera kusiyanitsa zinthu zomwe zili ndi malire omveka bwino komanso zinthu zomwe zili ndi malire osadziwika bwino. Kusintha kwamtundu womaliza kumatchedwa kusiyanitsa sensitivity. Odwala ng'ala mwina sangamve zowoneka bwino zowoneka, koma kukhudzika kosiyana kumachepetsedwa kwambiri. Zinthu zowoneka zidzawoneka zamtambo komanso zosamveka, zomwe zimapangitsa kuti pakhale zochitika za halo.

3. Sinthani ndi Colour Sense
Lens ya mitambo ya wodwala ng'ala imayamwa kuwala kochuluka kwa buluu, zomwe zimapangitsa kuti maso asazindikire mitundu. Kusintha kwa nyukiliyasi ya lens kumapangitsanso kuwonekera kwa mtundu, ndikutayika kwa mitundu yowoneka bwino (makamaka blues ndi masamba) masana. Choncho odwala ng'ala amawona chithunzi chosiyana ndi anthu wamba.

●Momwe mungatetezere ndi kuchiza ng'ala?
Cataract ndi matenda ofala komanso omwe amapezeka pafupipafupi mu ophthalmology. Chithandizo chachikulu cha ng'ala ndi opaleshoni.
Odwala okalamba okalamba sakhala ndi vuto lalikulu pa moyo wa masomphenya a wodwalayo, nthawi zambiri mankhwalawa ndi osafunika. Amatha kuwongolera kuchuluka kwazomwe zikuchitika kudzera mumankhwala amaso, ndipo odwala omwe ali ndi kusintha kwa refractive ayenera kuvala magalasi oyenera kuti azitha kuwona bwino.
Pamene ng'ala ikukulirakulira ndipo kusawona bwino kumakhudza kwambiri moyo watsiku ndi tsiku, ndiye kuti muchitidwa opaleshoni. Akatswiri amanena kuti masomphenya a postoperative ndi osakhazikika mu nthawi ya convalescence mkati mwa mwezi wa 1. Nthawi zambiri odwala amafunika kuyezetsa ma optometry pakatha miyezi itatu atachitidwa opaleshoni. Ngati ndi kotheka, kuvala magalasi (myopia kapena kuwerenga galasi) kusintha kutali kapena pafupi masomphenya, kuti tikwaniritse bwino zithunzi kwenikweni.
