●Chii chinonzi cataract?
Ziso rakafanana nekamera iyo lens inoshanda sekamera lenzi muziso.Paunenge uchiri mudiki, iyo lens inoonekera, elastic uye zoomable.Somugumisiro, zvinhu zviri kure uye zviri pedyo zvinogona kuonekwa zvakajeka.
Nezera, kana zvikonzero zvakasiyana-siyana zvichikonzera shanduko yelens permeability uye metabolic kusagadzikana, iyo lenzi ine matambudziko eprotein denaturation, edema uye epithelial hyperplasia.Panguva ino, iyo lens yaimbove yakajeka sejelly inova turbid opaque, kureva necataract.
Hazvina mhosva kuti opacity ye lens yakakura kana idiki, inokanganisa chiono kana kwete, inogona kunzi cataract.
● Zviratidzo zvecataract
Zviratidzo zvekutanga zvecataract kazhinji hazvisi pachena, chete nekunyatsoona kwakajeka.Varwere vanogona kuzviona zvisiri izvo se presbyopia kana kuneta kweziso, nyore kupotsa kuongororwa.Mushure memetaphase, kupenya kwelenzi yemurwere uye chiyero chekusaona zvakanaka kunowedzera, uye kunogona kuve nekumwe kunzwa kusiri kujairika senge kaviri strabismus, myopia uye glare.
Zviratidzo zvikuru zvecataract ndezvi:
1. Kutadza Kuona
Iyo opacity yakatenderedza lens haigone kukanganisa chiono;zvisinei iyo opacity muchikamu chepakati, kunyange kana chiyero chiri chidiki kwazvo, chichakanganisa zvakanyanya kuona, izvo zvinokonzeresa chiitiko chekusaona uye kuona kuderera.Kana iyo lenzi iine makore zvakanyanya, kuona kunogona kuderedzwa kusvika pakuona kwechiedza kana kusaona.
2. Kuderedzwa kwekusiyana kwekunzwa
Muhupenyu hwezuva nezuva, ziso remunhu rinoda kusiyanisa zvinhu zvine miganhu yakajeka pamwe nezvinhu zvine miganhu isina kujeka.Rudzi rwekupedzisira rwekugadzirisa rwunodaidzwa kuti musiyano wekunzwa.Varwere veCataract vanogona kunge vasinganzwe zviri pachena kuderera kwekuona, asi musiyano wekunzwa wakaderedzwa zvakanyanya.Zvinhu zvinoonekwa zvichaonekwa zvakasviba uye zvisinganzwisisike, zvichikonzera halo phenomenon.

3. Shandura neColor Sense
Iyo cloudy lens yemurwere wecataract inotora mwenje weblue wakawanda, izvo zvinoita kuti ziso risanzwe kune mavara.Shanduko muruvara rwe nucleus yelens zvakare inokanganisa chiono cheruvara, nekurasikirwa kwekujeka kwemavara (kunyanya blues negirinhi) mukati mezuva.Saka varwere vecataract vanoona mufananidzo wakasiyana kubva kuvanhuwo zvavo.

●Nzira yekudzivirira uye kubata sei cataract?
Cataract chirwere chinowanzoitika uye chinowanzoitika muophthalmology.Mushonga mukuru wecataract kuvhiyiwa.
Varwere vekutanga senile cataract havana simba guru pahupenyu hwechiratidzo chemurwere, kazhinji kurapwa hakuna basa.Vanogona kudzora chiyero chekufambira mberi kuburikidza nemishonga yemaziso, uye varwere vane refractive shanduko vanofanira kupfeka magirazi akakodzera kuti vavandudze maonero.
Kana iyo cataract ikawedzera uye kusaona kwakashata kunokanganisa zvakanyanya hupenyu hwezuva nezuva, zvinoda kuvhiyiwa.Nyanzvi dzinoratidza kuti postoperative vision haina kugadzikana munguva ye convalescence mukati memwedzi we1.Kazhinji varwere vanofanira kuita ongororo yeOptometry mwedzi mitatu mushure mekuvhiyiwa.Kana zvichidikanwa, pfeka magirazi (myopia kana girazi rekuverenga) kuti ugadzirise chiono chiri kure kana padyo, kuitira kuti uwane zvirinani maitiro ekuona.
