Yini i-aphakia?

I-Aphakia yisimo esibandakanya ukungabi nayo i-lens yamehlo. Ilensi yeso lakho yisakhiwo esicacile, esiguquguqukayo esivumela iso lakho ukuthi ligxile. Lesi simo sivame kakhulu kubantu abadala abane-cataract, kepha singathinta nezinsana nezingane.

Ziyini izimpawu ze-aphakia?

Uphawu oluyinhloko lwe-aphakia ukungabi nelensi. Lokhu kungaveza ezinye izimpawu, njenge:

• ukungaboni kahle
• inkinga yokugxila ezintweni
• izinguquko ekubukeni kombala, okubandakanya imibala ebonakala iphelile
• unenkinga yokugxila entweni njengoba ibanga lakho kuyo liyashintsha
• ukubona kude, noma inkinga yokubona izinto eduze

Yini ebangela i-aphakia?

Isifo senkwethu

I-cataract ingenza amehlo akho abukeke enesibindi futhi abangele umbono onamafu. Zibangelwa amaprotheni ahlangana ndawonye kwi-lens, okuvame ukwenzeka ngokukhula. Lokhu kwenza kube nzima ngelensi yakho ukukhipha ukukhanya ku-retina yakho, okuholele ekubukekeni kwesibhakabhaka. I-cataract ivame kakhulu, ithinta abantu baseMelika abangaba yizigidi ezingama-24.4 abaneminyaka engama-40 noma ngaphezulu, ngokusho kweAmerican Academy of Ophthalmology.

Ezimweni ezingavamile, izingane zizalwa zinolwelwesi lwamehlo. Lokhu kuvame ukubangelwa izakhi zofuzo noma ukuvezwa kwezifo ezithile, njengenkukhu.

Khuluma nodokotela wakho uma wena noma ingane yakho unezimpawu ze-cataract ukuze zikwazi ukukhipha noma yiziphi ezinye izinkinga zamehlo.

Izakhi zofuzo

Ezinye izingane zizalwa zingenamalensi wamehlo. Lesi sigaba se-aphakia sinezinhlobo ezimbili, ezibizwa nge-primary congenital aphakia kanye ne-apgenia yesibili yokuzalwa.

Izingane ezine-aphakia yokuzalwa eyinhloko zizalwa zingenamalensi, imvamisa ngenxa yezinkinga zokukhula noma ukuguquka kwezakhi zofuzo.

Izingane ezine-aphakia yokuzalwa yesibili zinelensi, kodwa ziyamuncwa noma zivalelwe ngaphambi noma ngesikhathi sokuzalwa. Lolu hlobo lwe-aphakia luphinde luhlotshaniswe nokuchayeka ku-virus, njenge-rubella yokuzalwa.

Ukulimala

Izingozi nokulimala ebusweni bakho kungalimaza i-lens yakho noma kuyenze ikwazi ukungena ngaphakathi kweso lakho.

Itholakala kanjani i-aphakia?

I-Aphakia ivame ukutholakala inesivivinyo esijwayelekile se-ophthalmic. Udokotela wakho futhi angahlola iris yakho, i-cornea, ne-retina.

Yelashwa kanjani i-aphakia?

Ukwelapha i-aphakia kuvame ukufaka ukuhlinzekwa kwezingane nabadala.

Kubalulekile ukuthi izingane ezine-aphakia zihlinzwe ngokushesha okukhulu ngoba amehlo azo akhula ngokushesha okukhulu. I-American Academy of Pediatrics incoma ukuthi izingane ezine-aphakia zihlinzwe lapho sezinenyanga cishe eyodwa ubudala. Bazodinga izingilazi noma amalensi wokuxhumana akhethekile abangalala kuwo futhi bawagqoke isikhathi eside ngemuva kokuhlinzwa. Bangathola ukufakwa kwelensi yokufakelwa uma sebenonyaka owodwa ubudala.

Ukuhlinzwa kwabantu abadala abane-aphakia kuvame ukubandakanya ukususa i-lens eyonakele uma kudingeka nokufaka okufakelwayo. Inqubo, evame ukwenziwa kusetshenziswa ukubulala izinzwa kwasendaweni, ingathatha ngaphansi kwehora. Udokotela wakho angakunikeza amalensi noma izibuko zokuxhumana ngemuva kokuhlinzwa ukuze uthuthukise umbono wakho.

Ingabe i-aphakia idala noma yiziphi izinkinga?

Iningi labantu lilulama kalula ekuhlinzweni kweso, kepha kunezinkinga ezimbalwa ezingaba khona.

I-glaucoma ye-Aphakic

Ukuba nanoma yiluphi uhlobo lokuhlinzwa kwamehlo kungakhuphula ubungozi bokuthola i-glaucoma. Lokhu kwenzeka lapho ukwakha ingcindezi ngaphakathi kweso kulimaza imizwa yakho ye-optic. Uma ishiywe ingalashwa, i-glaucoma ingaholela ekulahlekelweni kombono. Ngemuva kokuhlinzwa noma yiluphi uhlobo, qiniseka ukuthi ulandela izivivinyo zamehlo ezijwayelekile ukubheka i-glaucoma.

Ukuhlukaniswa kwe-retinal

Abantu abake balimala iso noma bahlinzwa nabo basengozini enkulu yokuthola i-retina ethintekile. I-retina inama-receptors abukwayo aguqula izithombe zibe yimizwa kagesi, ethunyelwa ebuchosheni. Kwesinye isikhathi i-retina iyanqamuka futhi isuke ezicutshini eziyibambile.

Izimpawu ze-retina ehlanganisiwe zifaka:

• ukubona amabala noma ukukhanya kokukhanya
• ukulahlekelwa kombono (ohlangothini) umbono
• umbala wobumpumputhe
• ukungaboni kahle

Thola ukwelashwa ngokushesha uma ucabanga ukuthi une-retina ehlanganisiwe ngoba ingaholela ekubeni ungaboni ngokuphelele ngaphandle kokwelashwa okufika ngesikhathi.

Ibutho le-Vitreous

I-vitreous humor yinto efana ne-gel egcwalisa ingaphakathi leso lakho futhi inamathiselwe ku-retina. Kokubili ukuguga nokuhlinzwa kwamehlo kungadala ushintsho kumahlaya we-vitreous. Lezi zinguquko zingadala ukuthi isuke kwi-retina, okuholele ekutholakaleni kwe-vitreous.

Ibutho le-vitreous ngokuvamile alibangeli zinkinga. Kodwa-ke, kwesinye isikhathi amahlaya we-vitreous adonsa kanzima kwi-retina ukuthi idala imbobo noma ithimba le-retina.

Izimpawu ze-vitreous detachment zifaka phakathi ukubona:

• amachashazi afana nobulembu embonweni wakho
• ukukhanya kokukhanya kumbono wakho wangaphandle

Uma une-vitreous detachment, sebenza nodokotela wakho ukuze uqiniseke ukuthi ayibangeli zinkinga ezingeziwe.

Ukuphila ne-aphakia

I-Aphakia kubo bobabili abadala nezingane ingalashwa kalula ngokuhlinzwa. Vele uqiniseke ukuthi ulandelela izivivinyo zamehlo ezijwayelekile ukubheka noma yiziphi izinkinga.
