I-Astigmatism yisifo lapho isisindo se-optical iso (sphericity) sephukile, ngenxa yokuthi imilayezo ebonwa yi-system ebonakalayo ayigxile kwelinye iphuzu futhi, lapho kungekho khona ukwelashwa, umbono wehlisa futhi i-strabismus ingabonakala.
Izimpawu nokuxilongwa kwe-Eye Astigmatism
Njengoba i-astigmatism, kunezifo ezinjalo ezibukwayo:
- ikhanda kanye nobuhlungu emehlweni;
- umbono wezinto ezixhunyiwe noma eziphephile;
- umbono ongenangqondo.
Ngokusobala, lezi zimpawu zingaba izici zezifo eziningi zamehlo, ngakho-ke ukuqinisekisa ukuthi kuyadingeka ukuxilonga ochwepheshe ongakwazi ukuzihlola ngokuzimela isimo sombono lapho ebhekwa, noma esebenzisa i-computer yokuxilonga. I-last is more preferable, ngoba kanye nayo ungathola idatha enembile ngesici, lapho ukuphumelela kokwelashwa kuxhomeke khona.
Izindlela zokwelapha i-astigmatism
Ukwelashwa kwalesi sifo kungenziwa ngokusebenzisa izindlela ezahlukene, kuxhomeke kwizinga layo. Ukuhlinzwa kubhekwa njengendlela ephumelela kakhulu, kodwa kuyadingeka ukuba usebenzise kuwo kuphela ezimweni ezimbi kakhulu, uma ezinye ukwelashwa kuye kwabonakala kungasebenzi.
Ukwelashwa kwe-Astigmatism ekhaya
Ekhaya, ungenza ukuzivocavoca futhi usebenzise izindlela ezithile zomuntu ukuze ulondoloze ikhono lakho lokubona.
Ukwelashwa kwe-astigmatism namayeza omuntu kuhlanganisa ukudalwa kokudla okhethekile: kudla inqwaba ye-cherry, nokuphuza ama-decoctions we-blueberries kanye nesanqante esisha, ikhukhamba nesobho se-beet. Thatha lemithi yemvelo ephendukile, 1 ingilazi ngosuku.
Futhi, ukwelashwa kwe-astigmatism ngezinqubo zabantu kuhlanganisa inqubo enjalo: nsuku zonke lapho ugeza, uphazamisa emanzini abandayo. Lokhu kuthuthukisa ukujikeleza kwegazi futhi kunomphumela omuhle esimweni jikelele sohlelo lokubukwa.
Ukuzivocavoca amehlo nge-astigmatism kwenziwa izikhathi eziningana ngosuku, futhi ngamunye wabo unikezwa imizuzu engaphezu kwengu-10:
- Ukulungisa amehlo ezintweni eziseduze nakakhulu: hlala phambi kwewindi, uthathe ipensela bese uphonsela kude nawe u-40 cm. Gxila ezintweni ezikude ngaphandle kwefasitela imizuzwana embalwa, bese uqaphelisisa ipensela. Eminye imiqondo eseduze nasezindaweni eziseduze okungenani emizuzu emi-5.
- Kuye ngokuthi kunjani ukubukwa kunzima (okuqondile, okungaqondile, okudibeneyo), yenza ukulungiswa okuphakathi kulezi zikhombisi-ndlela.
Ukwelashwa kwe-astigmatism yeso ngosizo lwemithi esemthethweni
Imithi yokwelashwa iqukethe kuphela ukugcina izinga elikhona lesifo. Kuhlanganisa ukugqoka izibuko noma amalensi, nokuzivocavoca njalo nokugcina impilo enempilo, esebenzayo.
Ukwelashwa okuhlinzekwayo nezinhlobo zayo
Ukuze uphathe i-astigmatism ye-myopic, i-keratotomy isetshenziswa lapho kukhonjiswa okwenziwe i-cornea kuma-meridians ukuyenza buthaka.
Ukwelapha i-hypermetropic astigmatism isebenzisa i-thermokeratocoagulation, lapho inaliti yensimbi evuthayo ikwandisa ukuvinjelwa kwe-cornea,
Ukwelashwa kwe-Laser ye-astigmatism kwenziwa ngosizo lwesibhamu se-laser. Namuhla, kuyindlela yokuhlinzeka ehamba phambili kakhulu yokulungisa ukukhubazeka kwamehlo, okusheshayo futhi unciphisa izinkinga emva kokuhlinzwa. Le ndlela isetshenziselwa ukuphatha i-astigmatism eyinkimbinkimbi. Phakathi kwezinhlobo ezahlukene zokusebenza kwe-laser, i-keratomilez yabelwe: ngosizo lwayo izinhlobo ezimbili ze-astigmatism (i-myopic ne-hypermetropic) ziphathwa futhi inzuzo yukuthi ayikho umonakalo ezingxenyeni ezingenasici ze-cornea.
