Yintoni i-Astigmatism, indlela yokuchonga nokunyanga

Umxholo

I-Astigmatism yingxaki emehlweni ekwenza ukuba ubone izinto ezingacacanga kakuhle, zibangela iintloko kunye nokuqaqamba kwamehlo, ngakumbi xa inxulunyaniswa nezinye iingxaki zombono ezinje nge-myopia.

Ngokubanzi, i-astigmatism ivela ekuzalweni, ngenxa yokujika kwe-cornea egoso, erhangqileyo kwaye engeyo-ovali, ibangela imitha yokukhanya ijolise kwiindawo ezininzi kwi-retina endaweni yokugxila kwindawo enye, yenza umfanekiso ongacacanga , njengoko kubonisiwe kwimifanekiso.

I-Astigmatism iyanyangeka ngoqhaqho lwamehlo olunokwenziwa emva kweminyaka engama-21 kwaye edla ngokubangela ukuba isigulana siyeke ukunxiba iiglasi okanye iilensi zonxibelelwano ukuze sikwazi ukubona ngokuchanekileyo.

Uguquko oluncinci kwi-cornea luqhelekile emehlweni, ngakumbi njengoko usiba mdala. Ke ngoko, kuqhelekile ukufumanisa ukuba une-astigmatism emva kovavanyo lombono oluqhelekileyo. Nangona kunjalo, uninzi lwamatyala aneqondo elincinci kuphela, elingaguquki umbono kwaye, ke ngoko, alufuni nyango.

Uyazi njani ukuba yi-astigmatism

Ezona mpawu zixhaphakileyo ze-astigmatism zibandakanya:

• Jonga imiphetho yento ingajoliswanga;
• Bhidanisa iisimboli ezifanayo ezinonobumba H, M, N okanye amanani 8 no-0;
• Ukungakwazi ukubona imigca ethe tye ngokuchanekileyo.

Ke, xa unayo nayiphi na kwezi mpawu kuyacetyiswa ukuba uye kugqirha wamehlo wenze uvavanyo lombono, ufumanise isifo se-astigmatism kwaye uqalise ngonyango, ukuba kukho imfuneko yoko.

Ezinye iimpawu, ezinje ngamehlo adiniweyo okanye intloko, zinokuvela xa isigulana sinengxaki ye-astigmatism kunye nenye ingxaki yombono, njenge-hyperopia okanye i-myopia, umzekelo.

Uvavanyo lwe-Astigmatism lokwenza ekhaya

Uvavanyo lwasekhaya lwe-astigmatism luquka ukujonga umfanekiso ongezantsi ngeliso elinye livaliwe kwaye elinye livulekile, emva koko utshintshe ukufumanisa ukuba ngaba i-astigmatism ikhona kwiliso elinye okanye zombini.

Kuba ubunzima bombono kwi-astigmatism bunokuvela kufutshane okanye kude, kubalulekile ukuba uvavanyo lwenziwe kwimigama eyahlukeneyo, ukuya kuthi ga kwi-6 yeemitha ubuninzi, ukuchonga ukuba ngowuphi umgama i-astigmatism echaphazela umbono.

Kwimeko ye-astigmatism, isiguli siya kuba nakho ukujonga utshintsho emfanekisweni, njengemigca ekhaphukhaphu kunabanye okanye imigca egoso, ngelixa umntu onombono oqhelekileyo kufuneka abone yonke imigca yesayizi efanayo, inombala ofanayo kunye nomgama .

Unyango lwenziwa njani

Unyango lwe-astigmatism kufuneka luhlale lucetyiswa ngugqirha wamehlo, njengoko kufuneka kuchongwe inqanaba elichanekileyo le-astigmatism ukwazi ukuba zeziphi ezona zibuko zibalaseleyo okanye iilensi zonxibelelwano.

Ukongeza, njengoko kuqhelekile ukuba i-astigmatism ifunyaniswe kunye ne-myopia okanye i-hyperopia, kunokuba yimfuneko ukusebenzisa iiglasi kunye neelensi ezilungiselelwe zombini ezi ngxaki.

Unyango oluchanekileyo, olona khetho lufanelekileyo kukuhlinzwa ngamehlo, njengeLasik, esebenzisa i-laser ukuguqula ubume be-cornea kunye nokuphucula umbono. Funda ngakumbi malunga nolu hlobo lotyando kunye neziphumo zalo.

Nini ukubona ugqirha

Kuyacetyiswa ukuba uqhagamshelane nodokotela wamehlo xa ujonga utshintsho kumfanekiso xa usenza uvavanyo lwe-astigmatism ekhaya, ukuba ubona izinto ezingacacanga okanye ukuba uziva unentloko ngaphandle kwesizathu.

Ngexesha lokubonisana kubalulekile ukwazisa ugqirha ukuba:

• Kukho ezinye iimpawu, ezinjengeentloko okanye amehlo adiniweyo;
• Kukho iimeko ze-astigmatism okanye ezinye izifo zamehlo kusapho;
• Elinye ilungu losapho linxiba iiglasi okanye iilensi zonxibelelwano;
• Wayekhathazwa yinto ethile emehlweni, ezinje ngokubethwa;
• Unengxaki yesifo esithile seswekile okanye uxinzelelo lwegazi.

Ukongeza, kuyacetyiswa ukuba abaguli abanesifo seswekile okanye ezinye iingxaki zamehlo, ezinje nge-myopia, ukubona kude okanye i-glaucoma, mabenze idinga no-ophthalmologist unyaka nonyaka.
