Ngingaba Nama-Astigmatism Kokubili Amehlo?

Umbuzo: Ngingaba ne-astigmatism kokubili amehlo?

Impendulo: I- Astigmatism cishe njalo kwenzeka emehlweni womabili. Lesi simo singenzeka ngeso elilodwa kuphela kodwa ngokuvamile siwumphumela wokulimala ngokomzimba.

Kuyini i-Astigmatism?

I-Astigmatism yigama eliyinkimbinkimbi elisetshenziselwa ukuchaza ukungasebenzi kombono indlela esebenza ngayo. I-Astigmatism yinkinga yamehlo engabangela ukukhanya ukugxila kumaphoyinti amabili esikhundleni somunye.

Lesi simo singaba umphumela we-misshapen cornea. I-astigmatism ibangela abantu ukuba babe nombono ongenalutho, obuthakathaka noma obonakele. Kuyinto ingozi yombono lapho amehlo agxilisa ukukhanya kwe- retina ngamaphuzu amabili esikhundleni salunye kuphela. Abantu abane-astigmatism ngezinye izikhathi bakhononda ngombono ongenalutho, ophikisayo noma ohlangene. I-Astigmatism cishe ihlala njalo emehlweni amabili futhi ivame ukulinganisa phakathi kokubili. I-Astigmatism iningi lemali ngokuvamile izuzwe njengefa. I-Astigmatism ingabonakala kwelinye iso kodwa lokhu kuvame ukubangelwa ukulimala okubuhlungu.

Yini Ebangela I-Astigmatism?

I-Astigmatism ngezinye izikhathi ibangelwa i- cornea engavamile, i-dome ecacile efana nesakhiwo engxenyeni engaphambili yeso. I-cornea ingaba nezindawo ezithandekayo noma ezinamandla kunabanye, okuholela ekubonweni okuphambene. I- crystalline lens ngaphakathi kweso ingase iphinde ishintshwe kancane, kubangele i-astigmatism. Ngaphezu kwalokho, i-astigmatism ingabangelwa ijwabu leso elingenangqondo noma izicubu ezinzima ezicindezela phansi.

I-Astigmatism ivame kakhulu futhi ivame ukuphathwa noma ukulungiswa ngokugqoka izibuko noma contact lens. Ukuhlinzwa okuqhubekayo njengeLASIK noma i-astigmatic keratectomy kungasiza futhi ekunakekeleni i-astigmatism.

Okudingeka Ukwazi

I-Astigmatism, uma ishiywe ingalashwa, ingabangela izinkinga zombono ezicindezelayo. Uma une-astigmatism, ungaba nezimpawu ukukuxwayisa noma udokotela wakho.

Ezinye izimpawu ze-astigmatism zingenzeka zodwa, kodwa ezinye zezimpawu zingase zenzeke ndawonye ngesikhathi esifanayo. Uma ubona noma iyiphi yalezi zimpawu ezilandelayo, yenza i-aphoyintimenti nesazi sakho sokunakekelwa kweso ngokushesha ngangokunokwenzeka. (Ngokuvamile kunconywa ukuthi kube nokuhlolwa okujulile kwamehlo kanye ngonyaka ukuze kuqinisekiswe umbono omuhle kanye nokuvimbela noma ukuvula isifo se-iso.)

• Ukubukisa noma Umbono oPhambene

• Ukukhathala Kwamehlo

• Eyestrain

• Izinsizwa

• Ayikwazi ukufunda ukuphrinta okuncane

• Ukuklanywa kwamehlo okuqhubekayo

Ukuqaphela nokuphatha i-Astigmatism

Udokotela wakho wezilanga angase ahlole i-astigmatism ngokuqhuba izivivinyo ezihlukahlukene. Ezinye zezivivinyo ezisetshenziselwa ukuhlonza i-astigmatism zihlanganisa ukuhlolwa kombono okulula, ukuhlolwa okukhanyayo okukhanyayo, ukulinganisa kwe-cornea, noma ukudweba nge-elekthronikhi ebusweni beso.

I-Astigmatism iqondiswa ngokugxila emisebeni yokukhanya embonini eyodwa. Lokhu kungafezwa ngokubeka izibuko zeso noma othintana nabo, noma ukwenza i-astigmatic keratotomy.
