Okuqukethwe
I-glaucoma ithinta inzwa yamehlo, ethola amasignali ku-retina, izisebenze, futhi izidlulisele ku-visual cortex yobuchopho. Ngaphandle kokwelashwa, imicu yezinzwa iyafa, futhi ngeke kwenzeke ukubuyisela umbono.
Inkinga eyinhloko ku-glaucoma ukunqwabelana koketshezi oluningi lwe-intraocular, olunomzila wokuphuma ovimbile. Ngokumelene nesizinda sokuqoqwa koketshezi, ingcindezi ye-intraocular iyakhuphuka, okuholela ekubambeni kwenzwa ye-optic, ukubhujiswa kwayo kancane kancane. Uma le nqubo ingamiswa, izoholela ekuphuphuthekeni, okungabe sekuqedwa.
Nakuba ukulungiswa kwamehlo kungenye yezindlela zokwelapha i-glaucoma, kusetshenziswa kuphela ngokuhambisana nezinye izindlela zokwelapha. Yonke inkambo ikhethwa udokotela ngamunye, umgomo oyinhloko ukunciphisa umthwalo embonweni, ukubuyisela ukucaca kwawo nokuthuthukisa izinga lokuphila. Kodwa ingabe ama-contact lens angasetshenziswa ukulungisa amaphutha e-refractive?
Ngingakwazi ukugqoka amalensi okuxhumana nge-glaucoma?
Ukulungiswa ngezibuko akuzifanele zonke iziguli. Lokhu kungenxa yendlela yokuphila, ezemidlalo ezisebenzayo noma izici zobungcweti. Ngakho-ke, ukulungiswa kwelensi kuthathwa njengendlela elula kakhulu yokulungisa amaphutha e-refractive. Kodwa kuphakama umbuzo wemvelo, ingabe kuvunyelwe ukugqoka amalensi okuxhumana e-glaucoma ukuze kulungiswe amaphutha e-refractive?
Impendulo yalo mbuzo izonikezwa kuphela yi-ophthalmologist, kucatshangelwa izici eziningi ezizocaciswa ngemuva kokuhlolwa okuningiliziwe nokuphelele.

Kepha imvamisa izinto zamalensi okuxhumana azihlangani kahle namanye amaconsi e-glaucoma, udokotela angasho ukuthi alungise i-pathology. Ezinye izixazululo zokwelapha i-glaucoma zingathinta ukubonakala kwe-lens, izici zayo zomzimba, ngakho awukwazi ukusebenzisa amaconsi ngesikhathi sokugqoka imikhiqizo.
Uma udinga ukukhetha izindlela zokulungiswa kokuxhumana ezizokwenza ngcono umbono ku-glaucoma, kodwa ngesikhathi esifanayo ngeke zilimaze amehlo, udinga ukuxhumana ne-ophthalmologist.

Ngaphandle kokwelashwa, kuyathuthuka, futhi iziguli ezine-glaucoma zibona kabi kakhulu kunalezo ezinenkinga yokubona eduze noma ukubona kude. Futhi ngokufanele, badinga ukulungiswa okuphelele kokuphazamiseka okubukwayo. Ubukhulu bokukhubazeka kokubona bunqunywa ngokuyinhloko izinga lokulimala kwenzwa ye-optic, ngoba yiyona edlulisela amasignali esuka kuyi-retina kuya ebuchosheni.
Ama-contact lens, uma ekhethwe kanye nodokotela, angakwazi ukuxazulula ezinye zezinkinga ze-refraction, athuthukise i-acuity ebonakalayo futhi anciphise ukucindezeleka kwamehlo. Ungasebenzisa kokubili ama-lens athambile, akhululekile ukugqoka, futhi aqinile, angena kumagesi, kodwa i-ophthalmologist enolwazi ngesikhathi sokuqokwa ingakhetha uhlobo lomkhiqizo.
Uzonquma ubukhulu bephutha le-refractive, ahlole isimo sezicubu zamehlo bese ekhetha amamodeli athile.
Uyini umehluko phakathi kwamalensi e-glaucoma namalensi ajwayelekile?
Ngokuvamile, cishe zonke izinhlobo zamalensi zifanelekile, imikhiqizo ayinazo izici eziqondene nalesi sifo. Kubalulekile kuphela ukunquma kusengaphambili ukuthi yiziphi izidakamizwa okufanele zisetshenziswe esigabeni sokuqala sesifo.
