Ingabe nawe ubona izinto zingacacile? Kungenzeka ukuthi kungenxa ye-astigmatism!

Wake waphawula ukuthi ezinye izinhlamvu azicacile, zibukeka zinwebekile kancane? Noma uma ushayela ebusuku, ubona imigqa emincane ezungeze izibani emgwaqweni, noma ukukhanya kubonakala kunwebekile? Ngezinye izikhathi singase sicabange ukuthi kumane nje kukhathala kancane kwamehlo ethu. Kodwa lokhu kungaba ngenxa yesimo samehlo esincane esibizwa ngokuthi i-astigmatism . Ungakhathazeki, lokhu kuyinto abantu abaningi abanayo, futhi ingalungiswa. Namuhla, sizokhuluma ngalokhu kalula, ngendlela ongayiqonda.

Kuyini i-Astigmatism?

Kalula nje, i-astigmatism iyinkinga encane ngendlela ukukhanya okungena ngayo emehlweni ethu. Uma sikhuluma iqiniso, ibangelwa kakhulu ushintsho oluncane esimweni sengxenye esobala ngaphambili kwamehlo ethu, i-cornea . Ngezinye izikhathi, ingabangelwa noshintsho esimweni selensi ngaphakathi kweso.

Cabanga nje, iso eliphilile line-cornea eyindilinga enhle, njengebhola. Ngemuva kwalokho, imisebe yokukhanya evela ngaphandle idlula kule cornea bese igxila endaweni eyodwa ngaphakathi kweso, okuyi-retina. Yilapho-ke sibona khona konke ngokucacile.

Kodwa umuntu one-astigmatism une-cornea ebunjwe njengebhola lombhoxo, noma ende kancane njengeqanda, noma egobile ohlangothini olulodwa. Kwenzekani uma lokho kwenzeka? Lapho imisebe yokukhanya ingena esweni, ayigxili endaweni eyodwa. Kunalokho, igxila ezindaweni eziningana, noma njengomugqa owodwa. Yilapho sibona khona izinto zingacacile, zeluliwe, futhi ngezinye izikhathi sengathi zimbili. Kufana nokuthi sibheka esibukweni esiphukile.

Isibonelo, uhlamvu "D" lungase lubukeke njengo-"B", noma indilinga ingase ibukeke njenge-oval. Yilokhu okwenzeka kakhulu nge-astigmatism.

Kungani kwenzeka i-astigmatism? Ziyini izimbangela?

Kunzima ukukhomba imbangela eyodwa ye-astigmatism, kodwa kunezici eziningana eziyinhloko ezibangela lokhu:

• Ufuzo: Lokhu kuvame ukwenziwa ngofuzo. Lokhu kusho ukuthi uma abazali bakho noma othile emndenini wakho enalesi simo, kungenzeka kakhulu ukuthi ube naso. Abantu abaningi bazalwa benalesi simo esingalingani se-cornea.
• Ukulimala Kwamehlo: Uma okuthile kushaya noma kulimaze iso, ukuma kwe-cornea kungashintsha ngezinye izikhathi. Lokhu kungaba yimbangela ye-astigmatism.
• Ukuhlinzwa Kwamehlo: Ngemva kokuhlinzwa kwamehlo, njengokuhlinzwa kwe-cataract, ukuma kwe-cornea kungashintsha kancane. Kodwa-ke, lokhu akwenzeki kuwo wonke umuntu.
• Izimo Zamehlo: Ezinye izimo zamehlo ezingavamile, njengeKeratoconus , zingabangela ukuthi i-cornea ibe mncane futhi ibe yi-cone. Lokhu futhi kuyimbangela enkulu ye-astigmatism.
• Ukuhlikihla noma ukuhlikihla amehlo akho: Ukuhlikihla amehlo akho ngamandla noma ukufaka ukucindezela ezinkopheni zakho isikhathi eside kuye kwabonakala kwezinye izifundo ukuthi kushintsha isimo se-cornea. Kodwa-ke, lokhu akuyona imbangela evamile kakhulu.

Into ebalulekile ukuthi, kungakhathaliseki ukuthi izimbangela ziyini, i-astigmatism iyisimo esingalawulwa futhi silungiswe .

Wazi kanjani ukuthi une-astigmatism? Ziyini izimpawu?

Uma une-astigmatism, ungase ube nezimpawu ezahlukahlukene. Akuwona wonke umuntu obhekana nazo ngendlela efanayo. Abanye abantu bangase bangazizwa bengakhululekile kangako uma bezizwa kancane.

Nazi ezinye izimpawu ezivamile :

• Umbono ofiphele noma ophambene: Lolu uphawu oluyinhloko. Izinto eziseduze kanye nalezo ezikude zingase zibonakale zifiphele futhi zingacacile. Ezinye izinto, njengezinhlamvu nemigqa, zingase zibonakale ziphambene.
• Ukucindezeleka kwamehlo: Uma ufunda incwadi, ubuka ikhompyutha, noma ubuka ithelevishini isikhathi eside, amehlo akho angase azizwe ekhathele kakhulu futhi esinda.
• Ubuhlungu bekhanda: Ubuhlungu bekhanda bungaba khona, ikakhulukazi ngemva kokwenza umsebenzi odinga ukusetshenziswa kwamehlo womabili. Lokhu kungase kube ngenxa yokuthi amehlo asebenza kakhulu.
• Ukufiphaza amehlo: Ngenxa yokuthi awukwazi ukubona kahle, ungase ulingeke ukuthi ufiphaze amehlo akho ukuze ubone izinto kahle.
• Ubunzima bokubona ebusuku: Ebusuku, ikakhulukazi uma ushayela, ungase ubone ukukhanya noma ama-halo azungeze izibani. Lokhu kungenza kube nzima ukubona umgwaqo ebusuku.
• Amehlo avuthayo noma abomvu: Abanye abantu bangase bazizwe bebomvu noma bebomvu njalo.
• Ukubona kabili esweni elilodwa: Lokhu akuvamile, kodwa abanye abantu bangabona izinto ezimbili ngisho nangeso elilodwa.

Uma unesinye noma ngaphezulu salezi zimpawu, kungcono ukufuna iseluleko sezokwelapha.

Unquma kanjani ngokunembile ukuthi une-astigmatism?

Ungacabangi ukuthi une-astigmatism ngoba nje unalezi zimpawu. Kodwa uma unokungabaza, kufanele nakanjani ubonane nodokotela wamehlo noma udokotela wamehlo ukuze ahlolwe amehlo akho.

Basebenzisa izindlela ezahlukene ukuhlola amehlo akho:

• Ukuhlolwa Kokubona Okubukhali: Uzocelwa ukuthi ufunde ishadi elinezinhlamvu nezinombolo. Lokhu kungalinganisa ubukhali bakho bokubona.
• I-Keratometer noma i-Corneal Topography:Lawa madivayisi angalinganisa ngokunembile ukugoba, noma ukuma, kwe-cornea yakho. Lokhu kungasiza ekunqumeni ukuthi une-astigmatism nokuthi inzima kangakanani.
• I-Autorefractor: Lena futhi idivayisi esebenzisa ukukhanya ukuthola umbono oqondile wokuthi hlobo luni lwelensi iso eliyidingayo.
• I-Phoropter kanye ne-Retinoscope: I-phoropter umshini obamba ubuso bakho phambi kwakho bese ushintsha amalensi ngalinye ngalinye, ubuza, "Ingabe lokhu kucacile? Ingabe lokho kucacile?" Udokotela ukhanyisa iso lakho nge-retinoscope bese ebheka ukuthi ukukhanya kuphenduka kanjani ngaphakathi kweso. Yile ndlela othola ngayo umuthi ofanele wena.

Zonke lezi zivivinyo azibuhlungu, ngakho-ke asikho isizathu sokwesaba.

Yiziphi izindlela zokwelapha i-astigmatism?

Izindaba ezinhle ukuthi i-astigmatism yisimo esingalungiswa cishe ngokuphelele . Udokotela wakho uzokhetha ukwelashwa okufanele kakhulu ngokusekelwe ezicini ezifana nezinga le-astigmatism yakho, iminyaka yakho, kanye nendlela yakho yokuphila.

Kunezindlela ezintathu eziyinhloko zokwelapha:

1. Izibuko (Izibuko)

Lena indlela yokwelapha evame kakhulu futhi elula kakhulu. Abantu abane-astigmatism banikezwa izibuko ezinamalensi ayisilinda aklanywe ngokukhethekile. Lawa malensi agxila imisebe yokukhanya engahlangani endaweni eyodwa ngenxa yokuma okungalingani kwe-cornea endaweni eyodwa ku-retina. Ngemuva kwalokho ungabona kahle.

2. Amalensi Okuxhumana

Ama-contact lens ayindlela enhle kubantu abangafuni ukugqoka izibuko noma abadlala imidlalo. Kukhona ama-contact lens e-toric aklanyelwe ngqo i-astigmatism. Lawa ahlukile kancane kuma-contact lens avamile. Angena kahle ngaphakathi kweso futhi alungisa i-astigmatism. Kwezinye izimo ezinzima ze-astigmatism, kusetshenziswa uhlobo olubizwa ngokuthi ama-Rigid Gas Permeable (RGP) lens .

3. Ukuhlinzwa Kokuvuselela Umzimba

Lokhu kuhilela ukusebenzisa ama-laser ukuze kulungiswe kabusha i-cornea unomphela, kuqedwe i-astigmatism. Ngemva kwalokhu, ngeke kusadingeka ukuthi ugqoke izibuko noma ama-contact lens.

Kunezinhlobo eziningana ezidumile zokuhlinzwa:

• I-LASIK (I-Laser-Assisted In Situ Keratomileusis): Kule nqubo, kwakheka i-flap encane ku-cornea bese kuthunyelwa i-laser beam ngaphansi kwayo ukuze ibumbe kabusha i-cornea.
• I-PRK (i-Photorefractive Keratectomy): Kule nqubo, ungqimba oluphezulu lwe-cornea luyasuswa bese kusetshenziswa umsebe we-laser.
• UKUMOMOTHEKA (Ukukhishwa Kwe-Lenticule Encane): Lena futhi indlela entsha yokuhlinzwa nge-laser.

Lokhu kuhlinzwa akufanele wonke umuntu. Udokotela uzonquma ukuthi uyakufanelekela yini lokhu noma cha ngokusekelwe ezicini eziningi, njengesimo samehlo akho, ubudala, kanye nempilo.

Ingabe izingane ezincane zithola i-astigmatism?

Yebo, i-astigmatism yisimo esibonakala ezinganeni ezincane. Ezinye izingane zizalwa zinalesi simo. Kubaluleke kakhulu ukuqaphela izinto ezinjalo kusenesikhathi ukuze ukubona kwezingane kukhule kahle. Ngaphandle kwalokho, kungathinta ukusebenza kwazo kwezemfundo, ukudlala, kanye nemisebenzi yansuku zonke.

Njengomzali, ungaqapha ingane yakho:

• Ingabe ingane ivame ukufiphaza amehlo?
• Ingabe usondeza ubuso bakho kakhulu lapho ufunda izincwadi noma ubukela i-TV?
• Ingabe uvame ukukhuluma ngekhanda elibuhlungu?
• Ingabe amehlo akho abomvu futhi anamanzi?
• Uzama ukubona ngeso elilodwa uvale?

Uma ubona into efana nale, into engcono kakhulu ongayenza ukuyisa ingane yakho kudokotela wamehlo ngokushesha okukhulu. Uma ubona lezi zimpawu kusenesikhathi, zingelashwa ngezibuko nje.

Umyalezo okufanele siwuthathe kulokhu

Kulungile, ngakho-ke ngicabanga ukuthi manje usunombono ongcono nge-astigmatism.

Into ebalulekile ukuthi i-astigmatism akuyona into okufanele uyesabe. Yisimo esivame kakhulu futhi esingalungiseka.

• Uma uvame ukubona izinto zingacacile, ukucindezeleka, ukucindezeleka kwamehlo, noma ikhanda elibuhlungu, ungakushayi indiva futhi nakanjani bonana nodokotela wamehlo ukuze ahlolwe amehlo akho.
• Kubaluleke kakhulu ukuhlolwa kwamehlo akho njalo ngezikhathi ezithile. Lokhu kuzokusiza ukuthi ungagcini nje ngokubona izimo ezinjengalezi, kodwa futhi nezinye izinkinga ezihlobene namehlo kusenesikhathi.
• Sebenzisa izibuko noma ama-contact lens owanikezwe udokotela wakho ngendlela efanele futhi njalo.
• Nakekela ngokukhethekile umbono wezingane ezincane. Kubaluleke kakhulu ngekusasa lazo.

Amehlo akho angenye yezinto eziyigugu kakhulu onazo, ngakho-ke kungumthwalo wakho ukuwanakekela.
