I-Astigmatism isifo apho i-optical system yelihlo (i-sphericity) iphukile, ngenxa yokuba imilayezo ebonwa yinkqubo ebonakalayo ingagxininisa kwelinye iphuzu kwaye, ekungabikho kwonyango, umbono unganciphisa kwaye umonakalo ungabonakala.
Iimpawu kunye nokuxilongwa kwe-Eye Astigmatism
Nge-astigmatism, kukho iziphene ezibonakalayo:
- intloko kunye nentlungu emehlweni;
- Umbono wezinto ezixhamliweyo okanye eziphambeneyo;
- mbono o
Ngokucacileyo, le miqondiso ingabonakalisa izifo ezininzi zamehlo, ukwenzela ukuba kuqinisekiswe ukuba kuyimfuneko ukuxilonga oyingcali onokuzimela ngokuzimeleyo isimo sombono xa sibhekwa, okanye sisebenzisa i-computer diagnostics. Olu hlobo lokugqibela lukhethwa, kuba kunye nayo unokufumana iinkcukacha ezichanekileyo kwisiphene, apho ukusebenza kwonyango kuxhomekeke khona.
Izindlela zokonyangwa kwe-astigmatism
Ukunyangwa kwesi sifo kungenziwa ngokusetyenziswa kweendlela ezahlukeneyo, kuxhomekeke kwisiganga sayo. Ugqirha uthathwa njengesona siphumelele, nangona kubalulekile ukuba sisebenzise kuwo kuphela kwiimeko ezimbi kakhulu, xa kukho unyango olungenakusebenza.
Ukwelashwa kwe-Astigmatism ekhaya
Ekhaya, unokwenza umzimba kwaye usebenzise iindlela ezithile zokugcina ubuchule bakho bokubona.
Ukwelashwa kwe-astigmatism kunye nezilwanyana ezibandakanya ukudalwa kokutya okukhethekileyo: ukutya ukutya okuninzi, nokuphuza i-decoctions ye-blueberries kunye ne-carrot entsha, ikhukhamba kunye ne-beet juice. Thatha la mayeza angokwemvelo, u-1 ingilazi ngosuku.
Kwakhona, unyango lwe-astigmatism kunye neendlela eziqhelekileyo ziquka inkqubo enjalo: yonke imihla xa uhlamba, uphakamise amehlo emanzini abandayo. Oku kuphucula ukujikeleza kwegazi kwaye kunemiphumo emihle kwiimeko eziqhelekileyo zeenkqubo ezibonakalayo.
Ukuzivocavoca kwamehlo kunye ne-astigmatism kwenziwa maxesha amaninzi ngemini, kwaye ngamnye wabo unikwe ngaphezu kwemizuzu eyi-10:
- Ukulungiswa kwamehlo afutshane nakwizinto ezikude: yima phambi kwefestile, uthathe ipensela uze uyikhuphe kude nawe u-40 cm. Gxila kwizinto ezikude ngaphandle kwefestile imizuzwana embalwa, kwaye ngokukhawuleza ugxininise ingqalelo kwipensile. Eminye iindawo ezikude kunye neendawo ezikufutshane ubuncinane emizuzu emi-5.
- Kuxhomekeke kukuphi uhlobo lokubukela kunzima (ukutshintsha, ukulandelana, ukudibanisa), yenza ukulungiswa okuphakathi kwezi zikhokelo.
Unyango lwe-astigmatism yeso ngoncedo lwamayeza aseburhulumenteni
Unyango olulondolozayo luquka kuphela ukugcina iqondo elikhoyo lesi sifo. Iquka ukugqoka iiglasi okanye iilensi, kunye nokuzivocavoca rhoqo nokugcina impilo ephilileyo, esebenzayo.
Unyango oluphandwayo kunye neentlobo zalo
Ukunyanga i-astigmatism ye-myopic, i-keratotomy isetyenziswe xa kutywelwa kwi-cornea kwi-meridians ukuyenza buthathaka.
Ukuphatha i-hypermetropic astigmatism isebenzisa i-thermokeratocoagulation, apho inaliti yensimbi evuthayo ikwandisa ukukhawuleka kwe-cornea,
Ukwelashwa kwe-Laser ye-astigmatism kuqhutywa ngoncedo lwesithwathwa se-laser. Namhlanje, yindlela ephuculweyo yokucwangcisa ukukhubazeka kwamehlo, okukhawuleza nokunciphisa iingxaki emva kokuhlinzwa. Le ndlela isetyenziselwa ukuphatha i-astigmatism enzima. Phakathi kweentlobo ezahlukeneyo zokusebenza kwe-laser, i-keratomilez yabelwe: ngoncedo lwazo ezimbini i-astigmatism (i-myopic kunye ne-hypermetropic) zonyango kwaye inzuzo yayo kukuba akukho monakalo kwizinto eziqhelekileyo ze-cornea.
