I-Hypermetropia ibizwa ngokuthi i-anomaly yombono, lapho, lapho ubuka izinto ezikude, isithombe asigxile ku-retina, kodwa ngemuva kwayo. Ngenxa yalokhu, umuntu ubona izinto ezingekho ngokucacile, kodwa, njengomthetho, unombono omuhle ode kakhulu (ngokuvamile obona isikhathi eside noma i-presbyopia). Ngesikhathi esifanayo, ngezinhlobo zokubeletha ze-hyperopia, umuntu angase abe nesimo sengqondo esibi ngokujwayelekile, kungakhathaliseki ukuthi ibanga lendaba ecatshangelwayo.
Izimbangela ze-hyperopia
Cishe zonke izingane ezisanda kuzalwa zihlushwa yi-hypermetropia ngenxa yokuthi i-eyeball e-axis anesimo-posterior isincane kakhulu. Njengoba ingane ikhula, umbono ujwayelekile. Kodwa uma lokhu kungenzeki, khuluma nge-anomaly yokuzalwa, okubangelwa amandla obuthakathaka okuvuvukala we-cornea noma i-lens.
Abantu asebekhulile bayazi ukuthi ukubhekwa phambili kuyinkimbinkimbi, hhayi ukushiya noma ngisho nokwazi ukukhetha izibuko ngaphandle kwemithi yendlela yokuhlolwa, ukuthembela ekuzweleni, okwenza ukuthi i-ophthalmologist ibe yinto eshaqisayo. Njengoba uneminyaka yobudala, i-lens ilahlekelwa ikhono lokuguquka ngokuguquguqukayo, ngakho-ke ngemva kweminyaka engu-45 kufanele ifunde ngenkathi ihambisa le ncwadi kude emehlweni kunokwenzeka.
Izibuko ezibheke phambili
Uma sikhuluma ngama-pluses, sisho ama-dioptries ngokubhekwa phambili-lokhu kuyigugu ehlukanisa izinga le-anomaly. Ngakho-ke, nge-hyperopia emnene, ama-lens akhethwe kuze kube yi-+2.0 diopters; idijithi ejwayelekile iboniswa ngumbonakaliso we-+5.0, futhi ophakemeyo ngaphezu kuka +5.0.
Uma umuntu engasisebenzisi ekwelapheni kwemibono engabonakali, esizoxoxa ngayo, uxhumane ne- lens ngokubhekwa phambili noma izibuko ezivamile kuzokusiza ukuba ulahlekelwe ukukhathazeka uma usebenza nezinto ezikude - zithathwa kuphela udokotela.
Indlela yokulungisa i-hyperopia?
I-microsurgery yanamuhla yeso inezindlela eziningi zokubuyisela umbono. Emashumini ambalwa eminyaka adlule ukuphumelela kule ndawo kwenziwa yindlela yokucubungula kwi-cornea (radial keratotomy). Lapho izibalo ezincane ziphulukiswa, isimo se-cornea sashintsha, okwakungenwe ukwanda kwamandla ayo optical.
Manje ukwelashwa okunjalo kubhekwa njengengozi, kungalindelekile futhi kungonakali, kusukela ukuphulukiswa sekude isikhathi eside, ngaphandle kwalokho, umuntu akakwazi ukusebenza kokubili amehlo ngesikhathi esisodwa.
Indlela ethandwa kakhulu futhi evunyelwe ngayo namuhla ukulungiswa kombono we-laser, okwenziwa ngosuku olulodwa. Igoli le-laser ilungisa ukuma kwe-cornea ngaphandle kokungena emigqeni ejulile. Ngendlela ephakeme yokubhekwa kwemvelo yayisetshenziswe ekufakweni kwe-lensi yokufakelwa noma amalensi langempela.
Odokotela babheka lezi zinqubo njengendlela ephephile futhi banikeza amaphesenti amancane ezingozi, kodwa iziguli eziningi, ngisho no-1% wamathuba okuba nomphumela omubi wokulungiswa kombono ingxabano ngokumelene nalo. Ngoba abaningi bavele bagqoke izibuko noma ama-lens ekubukeni. Imithi yokwelapha iyakholelwa ukuthi lokhu kuqhubekela phambili embukisweni.
Ukulungiswa kwe-hyperopia ngendlela engasebenzi
Imithi yendabuko ibonisa ukuthatha infusions kusuka Grasslands umvini kanye marsh sweet njengendlela yokugqugquzela umbono.
Emashumini eminyaka edlule, izindlela ezingavamile zokulwa ne-hyperopia, i-myopia ngisho ne-cataracts. Le ndlela yasungulwa udokotela wemithi engeyona yendabuko uMnu. Norbekov. Isiguli sinikezwa nsuku zonke ukwenza umzimba ohlangene , umzimba olula wamehlo, landela ukuma, ukumomotheka futhi ukholelwe ukuthi lokhu kuzosebenza. Le ndlela inokugxeka kaningi odokotela bendabuko, kodwa inethiwekhi inezinombolo eziningi zokubuyekezwa ekusebenzeni kokwelashwa okunjalo.
