Ukuhlinzwa kwe-cataract kuwukuhlinzwa okwenziwa kakhulu emhlabeni naseFrance, cishe ngokuhlinzwa okungama-700 unyaka ngamunye. Kungumsebenzi osheshayo futhi onobungozi obuncane obuyisela ukubona ngokufaka isigxivizo sokwenziwa esweni.

Ukuhlinzwa kwe-cataract ukuhlinzwa ukuze kukhishwe ilensi esweni elihlaselwe yilesi sifo futhi, ezimweni eziningi, esikhundleni salo kufakwa ilensi yokwenziwa.

Ngokuvamile, i-lens (i-lens yeso) icacile futhi isobala. Ngakho-ke le lensi ivumela ukudlula kokukhanya kubheke ku-retina, esebenza njengesikrini futhi evumela ukubona. Lapho i-cataract ikhula, i-lens iba i-opaque futhi lokhu kuthinta ukubona. Kuyisifo esivamile esihlasela abantu abangaphezu koyedwa kwabahlanu kusukela eminyakeni engu-65 futhi cishe ababili kwabathathu ngemva kweminyaka engu-85.

Uma lesi sifo sithuthuke kakhulu futhi senza ukuphila kwansuku zonke nemisebenzi evamile ibe nzima, udokotela angase asikisele ukuhlinzwa. Ukuhlinzwa kwe-cataract yiyona ndlela kuphela yokubuyisela umbono kahle uma isifo sesingenile.

Ukuhlinzwa kwe-cataract kwenziwa yi-ophthalmologist. Kuyinqubo esheshayo evame ukuthatha imizuzu eyi-15 kuya kwengama-30 ngaphansi kwe-anesthesia yendawo, okusho ukuthi isiguli sivukile ngesikhathi senqubo.

Ngesikhathi sokuhlinzwa, udokotela ohlinzayo uzokwenza ukusika okuncane (ukusika) esweni ukuze i-lens ethintekile ikhishwe. Ngemva kokuyikhumula, ubeka ilensi yepulasitiki encane ebizwa ngokuthi i-intraocular implant.

Uma womabili amehlo ethintekile, kuyodingeka ukuhlinzwa okubili okuhlukene futhi kuzokwenziwa ngokuhlukana kwamasonto ambalwa. Lokhu kwenza kube nokwenzeka ukubuyisela ukubona okuvamile esweni lokuqala elihlinziwe ngaphambi kokuhlinzwa kwesibili.

Kwezinye izimo, udokotela angase asikisele ukuhlinzwa okusizwa nge-laser. Lokhu kunjalo, isibonelo, lapho ifuna ukulungisa i-astigmatism ngesikhathi esifanayo nokususa i-cataract. Kulesi simo, ukusika kwesikhwama esine-lens kwenziwa nge-laser.

Ngokuvamile, ukuhlinzwa kwe-cataract kuyinqubo yokulaliswa ngaphandle. Okusho ukuthi, isiguli singaya ekhaya emini. Kodwa-ke, kungcono ukuhlela ukuthi kube khona ohamba naye ngoba iso elihlinziwe lizovalwa ngebhandishi futhi lokhu kungase kuphazamise ukungaboni ngokuphelele kuye ngesimo selinye iso. Ezimweni eziningi, ukusebenza kuvumela ukubuyiswa kombono okuhle kakhulu ngosuku olungemva kokuhlinzwa noma ezinsukwini ezimbalwa. Isiguli singabe sesiqala kabusha impilo yaso evamile yansuku zonke.

Ngemuva kokuhlinzwa, i-lens yokwenziwa iba yingxenye yeso futhi ayidingi ukwelashwa okwengeziwe noma ukunakekelwa okukhethekile. Kodwa-ke, kungenzeka ukuthi uzobhekana nokungakhululeki kwamehlo ngemva kwenqubo futhi ukwelashwa kwendawo okulwa nokuvuvukala kuyodingeka amasonto ambalwa.

Izinkinga ngemva kokuhlinzwa azivamile. Uma uzwa ubuhlungu obuningi noma ukuncipha kombono ezinsukwini nasemavikini alandelayo, kufanele uxhumane nodokotela wakho noma uye esibhedlela.

Ingozi yezinkinga inkulu uma kunesinye isifo samehlo noma isifo esibucayi esihlobene, njenge-glaucoma noma ukonakala kwe-macular. Kulokhu, ukusebenza kwe-cataract kungase kungathuthukisi umbono.
