Cataracts

I- cataract iwukufipha kwe-lens yamehlo, okuvamise ukuba sobala. Kubantu abane-cataracts, ukubona nge-lenses ezifiphile kufana nokubuka ngefasitela elikhazimulayo noma elikhanyayo. Ukubona okuphazamisekile okubangelwa yi-cataracts kwenza kube nzima ukufunda, ukuqhuba imoto ebusuku noma ukubona ubuso bomngani. I-cataracts eningi ithuthuka kancane futhi ayiphazamisi ukubona ekuqaleni. Kodwa ngokuhamba kwesikhathi, i-cataracts izophazamisa ukubona. Ekuqaleni, ukukhanya okukhulu nezikhombisi zamehlo zingasiza ekusingatheni i-cataracts. Kodwa uma ukubona okuphazamisekile kuchaphazela imisebenzi evamile, ukucathulwa kwe-cataract kungase kudingeke. Ngenhlanhla, ukucathulwa kwe-cataract kuyindlela ephephile, ephumelelayo.

Izimpawu ze-cataracts zifaka: Ukubona okuphazamisekile, okuphazamisekile noma okumnyama. Ukubona ubunzima ebusuku. Ukuqabuleka kokukhanya nokukhanya. Isidingo sokukhanya okukhanya ukuze ufunde nezinye imisebenzi. Ukubona “ama-halos” ezibani. Ukushintsha njalo kwelensi yezikhombisi noma yelensi yokuxhumana. Ukuphela noma ukukhanya kombala. Ukubona okubili emehlweni. Ekuqaleni, ukuphazamiseka kokubona okubangelwa yi-cataract kungathinta ingxenye encane yelensi yamehlo. Ungase ungaphawuli ukulahleka kokubona. Njengoba i-cataract ikhula, iphazamisa ingxenye enkulu yelensi yakho. Ukuphazamiseka okwengeziwe kuguqula ukukhanya okudlula ngelensi. Lokhu kungadala izimpawu ozibona kakhulu. Yenza i-aphoyintimenti yokuhlolwa kwamehlo uma uqaphela noma yikuphi ukushintsha kokubona kwakho. Uma uthuthukisa ukushintsha kokubona ngokuzumayo, njengokubona okubili noma ukukhanya okukhanya, ubuhlungu obukhulu besikhathi, noma isiphithiphithi esibuhlungu, bheka ilungu leqembu lakho lokunakekelwa kwezempilo ngokushesha.

Yenza i-aphoyintimenti yokuhlolwa kwamehlo uma ubona noma yiziphi izinguquko ekuqaleni kwakho. Uma uthuthukisa izinguquko ezingalindelekile zokubona, njengokubona okukabili noma ukukhanya okukhanya, ubuhlungu obukhulu beliso, noma ikhanda elibuhlungu ngokuzumayo, bheka ilungu leqembu lakho lokunakekelwa kwezempilo ngokushesha.

I-cataract eziningi zikhula lapho ukuguga noma ukulimala kushintsha inyama eyenziwe ilensi yamehlo. Amaprotheni nezinhlanzi ze-lens ziqala ukuphazamiseka. Lokhu kubangela ukubona kube buthakathaka noma kube mnyama. \n\nEzinye izifo ezidluliselwa kubazali ezingabangela ezinye izinkinga zempilo zingandisa ingozi yakho yama-cataract. Ama-cataract angabangelwa ezinye izimo zamehlo, ukuhlinzwa kwamehlo kwangaphambili noma izimo zezokwelapha ezinjengesi-diabetes. Ukusetshenziswa kwemithi ye-steroid isikhathi eside kungabangela ama-cataract ukuba akhule. \n\nA cataract iyilensi efihliwe. I-lens ihlala ngemuva kwengxenye elimele amehlo akho, ebizwa ngokuthi yi-iris. I-lens igxila ukukhanya okudlula emehlweni akho. Lokhu kwenza izithombe ezicacile, eziqine ngemuva kwamehlo, ebizwa ngokuthi yi-retina. \n\Njengoba ukhula, ama-lens emehlweni akho aba mancane, angacaci futhi abe nzima. Ukuguga nezinye izimo zezokwelapha kungabangela amaprotheni nezinhlanzi ngaphakathi kwama-lens ukuba aphazamiseke futhi ahlangane ndawonye. Yilokhu okubangela ukufiphaza ema-lens. \n\Njengoba i-cataract ikhula, ukufiphaza kuba kubi kakhulu. I-cataract isakaza futhi ivinje ukukhanya njengoba kudlula nge-lens. Lokhu kuvimbela isithombe esicacile ukuba sifinyelele e-retina yakho. Ngenxa yalokho, ukubona kwakho kuyahlwita. \n\Ama-cataract avame ukwenzeka kokubili amehlo, kodwa hhayi ngaso sonke isikhathi ngesivinini esifanayo. I-cataract elinye iso ingaba imbi kunelinye. Lokhu kubangela umehluko wokubona phakathi kwamehlo. \n\Izinhlobo ze-cataract zihlanganisa: \n\n- Ama-cataract athinta i-center yelensi, abizwa ngokuthi ama-nuclear cataracts. I-nuclear cataract iqala ingabangela izinto ezikude ukuba zihlwithe kodwa izinto eziseduze zibonakale zicacile. I-nuclear cataract ingase iphinde ilungise ukubona kwakho kokufunda isikhathi esifushane. Kodwa ngokuhamba kwesikhathi, i-lens kancane kancane iphenduka iphuzi noma imnyama futhi yenza ukubona kwakho kube kubi. Kungaba nzima ukwahlukanisa imibala. \n- Ama-cataract athinta imiphetho yelensi, abizwa ngokuthi ama-cortical cataracts. I-cortical cataract iqala njengezinda ezimhlophe, ezinjenge-wedge noma imigqa emaphethelweni angaphandle e-lens cortex. Njengoba i-cataract ikhula kancane, imigqa isakazeka e-center futhi ithinta ukukhanya okudlula nge-lens. \n- Ama-cataract athinta ngemuva kwe-lens, abizwa ngokuthi ama-posterior subcapsular cataracts. I-posterior subcapsular cataract iqala njengendawo encane evame ukwakheka eduze ngemuva kwe-lens, ngqo endleleni yokukhanya. I-posterior subcapsular cataract ivame ukuphazamisa ukubona kwakho kokufunda. Ingase iphinde inciphise ukubona kwakho ekukhanyeni okukhulu futhi ibe nomswakama noma ama-halos azungeze izibani ebusuku. Lezi zinhlobo ze-cataracts zivame ukukhula ngokushesha kunabanye. \n- Ama-cataract owazalwa nawo, abizwa ngokuthi ama-congenital cataracts. Abanye abantu bazalwa nama-cataract noma bawathuthukisa ngesikhathi sobuntwana. La ma-cataract angadluliselwa kubazali. Angase futhi ahambisane nokutheleleka noma ukulimala ngesikhathi beselubili. \n\nLa ma-cataract angase futhi abangelwe izimo ezithile. Lokhu kungafaka i-myotonic dystrophy, i-galactosemia, i-neurofibromatosis uhlobo 2 noma i-rubella. Ama-congenital cataracts awawaphazami njalo ukubona. Uma enza kanjalo, avame ukususwa ngokushesha nje uma etholakala. \n\nAma-cataract owazalwa nawo, abizwa ngokuthi ama-congenital cataracts. Abanye abantu bazalwa nama-cataract noma bawathuthukisa ngesikhathi sobuntwana. La ma-cataract angadluliselwa kubazali.

Uma enza kanjalo, avame ukususwa ngokushesha nje uma etholakala.

Izinto ezandisa ingozi yakho yama cataracts zifaka phakathi:

• Ukukhula kweminyaka.
• I-Diabetes.
• Ukukhanya okukhulu kwelanga.
• Ukubhema.
• Ukukhuluphala.
• Umlando womndeni wama-cataracts.
• Ukulimala kwamehlo noma ukuvuvukala kwangaphambili.
• Ukuhlinzwa kwamehlo kwangaphambili.
• Ukusetshenziswa isikhathi eside kwemithi ye-corticosteroid.
• Ukusebenzisa utshwala ngokweqile.

Awekho ucwaningo oluye lwabonisa ukuthi ungayivimba kanjani noma uthintele ukukhula kwe-cataracts. Kodwa ochwepheshe bezempilo bacabanga ukuthi amasu ambalwa angasiza, kuhlanganise:

• Ukuhlolwa njalo kwamehlo. Ukuhlolwa kwamehlo kungasiza ekutholeni i-cataracts nezinye izinkinga zamehlo ezingeni lawo lokuqala. Buza iqembu lakho lezempilo ukuthi kufanele uhlolwe kaningi kangakanani amehlo.
• Ungabhemi. Buza ilungu leqembu lakho lezempilo ukuthi ungayekisa kanjani ukubhema. Imithi, ukwelulekwa namanye amasu ayakhona ukukusiza.
• Phatha ezinye izinkinga zempilo. Landela uhlelo lwakho lokwelashwa uma une-diabetes noma ezinye izimo zezokwelapha ezingandisa ingozi yakho ye-cataracts.
• Khetha ukudla okunempilo okuqukethe izithelo nemifino eminingi. Ukuthuthukisa ukudla kwakho ngezithelo nemifino kuqinisekisa ukuthi uthola amavithamini nezondlo eziningi. Izithelo nemifino zine-antioxidants. I-Antioxidants iyasiza ekugcineni impilo yamehlo akho. Ucwaningo aluye lwabonisa ukuthi i-antioxidants ngendlela yephukuthe ayikwazi ukuvimba i-cataracts. Kodwa ucwaningo olukhulu lwabantu luye lwabonisa ukuthi ukudla okunempilo okunamavithamini nemînerali kunciphisa ingozi yokuthuthukisa i-cataracts. Izithelo nemifino zinezibonelelo eziningi zempilo ezibonakalayo. Ukudla kwazo kuyindlela ephephile yokuthola amaminerali namavithamini anele ekudleni kwakho.
• Gqoka izibuko lelanga. Ukukhanya kwe-ultraviolet elangeni kungabangela i-cataracts. Gqoka izibuko lelanga ezivala imisebe ye-ultraviolet B uma ungaphandle.
• Nciphise ukusetshenziswa kotshwala. Ukuphila utshwala kakhulu kungandisa ingozi ye-cataracts. Khetha ukudla okunempilo okuqukethe izithelo nemifino eminingi. Ukuthuthukisa ukudla kwakho ngezithelo nemifino kuqinisekisa ukuthi uthola amavithamini nezondlo eziningi. Izithelo nemifino zine-antioxidants. I-Antioxidants iyasiza ekugcineni impilo yamehlo akho. Ucwaningo aluye lwabonisa ukuthi i-antioxidants ngendlela yephukuthe ayikwazi ukuvimba i-cataracts. Kodwa ucwaningo olukhulu lwabantu luye lwabonisa ukuthi ukudla okunempilo okunamavithamini nemînerali kunciphisa ingozi yokuthuthukisa i-cataracts. Izithelo nemifino zinezibonelelo eziningi zempilo ezibonakalayo. Ukudla kwazo kuyindlela ephephile yokuthola amaminerali namavithamini anele ekudleni kwakho.

Ukuze kutholakale ukuthi ukhona yini isifo se-cataract, udokotela wakho weziso uzobuyekeza umlando wakho wezokwelapha kanye nezimpawu. Bazokwenza futhi ukuhlolwa kwamehlo. Udokotela wakho angenza amavivinyo amaningana, okuhlanganisa: Ukuhlolwa kobona. Ukuhlolwa kobona, okuthiwa futhi ukuhlolwa kokubona okuqondile, kusebenzisa i-eye chart ukulinganisa ukuthi uyakwazi kangakanani ukufunda uchungechunge lwamagama. Ilinye iso lihlolwa ngesikhathi, kuyilapho elinye iso livalwe. Kusetshenziswa i-chart noma idivayisi yokubuka enamagama amancane. Ngale, udokotela wakho weziso uqonde ukuthi unobona lwe-20/20 noma unezinkinga zokubona. Ukuhlolwa komsungulo wamehlo. Ukuhlolwa komsungulo wamehlo, okuthiwa futhi i-slit lamp, kuvumela udokotela wakho weziso ukubona izakhiwo eziphambili zeso sakho eduze. Kubizwa nge-slit lamp ngoba kusebenzisa umugqa onamandla wokukhanya, i-slit, ukukhanyisa izakhiwo emehlweni akho. I-slit ivumela udokotela wakho ukubona lezi zakhiwo ezingxenyeni ezincane. Lokhu kwenza kube lula ukuthola noma yini engaba yiphutha. Ukuhlolwa kwe-retina. Ukuhlolwa kwe-retina kubheka emuva kwamehlo akho, okuthiwa yi-retina. Ukuze ulungiselele ukuhlolwa kwe-retina, udokotela wakho weziso ubeka amaconsi emehlweni akho ukuze avule abafundi bakho kabanzi, okuthiwa yi-dilation. Lokhu kwenza kube lula ukubona i-retina. Usebenzisa i-slit lamp noma idivayisi ekhethekile ebizwa nge-ophthalmoscope, udokotela wakho weziso angahlola ilensi yakho ngezimpawu ze-cataract. Ukuhlolwa kokucindezela kwe-fluid. Lo mvivinyo, okuthiwa futhi i-applanation tonometry, uqapha ukucindezela kwe-fluid emehlweni akho. Kunezinhlobo eziningi zamadivayisi ezikhona ukwenza lokhu.

Uma izibuko zakho zokubhalwa zingakwazi ukuqeda ukubona kwakho, ukwelashwa kuphela okuphumelelayo kwe-cataracts yiyona opharetha. Nini kufanele ucabangele ukucutshungulwa kwe-cataracts Xoxa nodokotela wakho wamehlo mayelana nokuthi ukucutshungulwa kulungele yini wena. Odokotela abaningi bamehlo bacebisa ukucatshangelwa kokucutshungulwa kwe-cataracts uma i-cataracts yakho iqala ukuthinta ikhwalithi yokuphila kwakho. Lokhu kungafaka ikhono lakho lokwenza imisebenzi yansuku zonke, njengokufunda noma ukuqhuba ebusuku. Kubantu abaningi, akukho luvalo lokukhipha i-cataracts ngoba ngokuvamile azilimazi amehlo. Kodwa i-cataracts ingaba mbi ngokushesha kubantu abanezinqubo ezithile. Lokhu kufaka i-diabetes, igazi eliphezulu noma ukukhuluphala. Ukulinda ukwenza ukucutshungulwa kwe-cataracts ngokuvamile ngeke kuthinte ukuthi ukubona kwakho kuphulukana kangcono kangakanani. Thatha isikhathi sokucabangela izinzuzo nezingozi zokucutshungulwa kwe-cataracts nodokotela wakho. Uma ukhetha ukungabi nokucutshungulwa kwe-cataracts manje, udokotela wakho wamehlo angase acebise ukuhlolwa okuqhubekayo kokulandelela ukuze abone ukuthi i-cataracts yakho iyaba mbi yini. Ukuthi uzombona kangaki udokotela wakho wamehlo kuncike esimweni sakho. Kwenzekani ngesikhathi sokucutshungulwa kwe-cataracts Ukuhlinzwa kwe-cataracts Khulisa isithombe Valela Ukuhlinzwa kwe-cataracts Ukuhlinzwa kwe-cataracts Uhlobo oluvamile kakhulu lokucutshungulwa kwe-cataracts lubizwa ngokuthi yi-phacoemulsification. Ngalesi sikhathi, iphuzu elithuthumela ngokushesha le-probe ye-ultrasound liqhekeza i-cataract. Odokotela bakho bese beyisusa i-lens, njengoba kubonakala esithombeni esiphezulu. Indlu yangaphandle ye-cataract, ebizwa ngokuthi yi-lens capsule, ngokuvamile ishiywa endaweni. Ngemva kokususa i-lens, udokotela wakho ubeka i-lens implant endaweni engenalutho ngaphakathi kwe-capsule lapho i-lens yemvelo yayisekhona khona, njengoba kubonakala esithombeni esingezansi. Ukuhlinzwa kwe-cataracts kuhilela ukususa i-lens efihliwe nokuyibeka nge-lens yemvelo. I-lens yemvelo, ebizwa ngokuthi yi-intraocular lens, ibekwe endaweni efanayo ne-lens yakho yemvelo. Ihlala iyinqobo ehlala njalo yamehlo akho. Kwabanye abantu, i-lenses yemvelo ayikwazi ukusetshenziswa. Kulezi zimo, uma i-cataract isiqediwe, ukubona kungalungiswa ngama-eyeglasses noma ama-contact lenses. Ukuhlinzwa kwe-cataracts ngokuvamile kwenziwa ngaphandle kwesibhedlela. Lokhu kusho ukuthi ngeke kudingeke uhlale esibhedlela ngemva kokucutshungulwa. Ngesikhathi sokucutshungulwa, udokotela wakho wamehlo usebenzisa imithi yokuthambisa indawo ezungezile amehlo akho. Uhlala uvukile ngesikhathi senqubo. Ukuhlinzwa kwe-cataracts kuphephile ngokuvamile. Noma kunjalo, kuhlanganisa ingozi yokutheleleka nokugqwala. Ukuhlinzwa kwe-cataracts futhi kukhuphula ingozi yokuthi i-retina ikhishwe endaweni. Lokhu kubizwa ngokuthi yi-retinal detachment. Ngemva kwenqubo, ungase ube buhlungu izinsuku ezimbalwa. Ukuphulukisa ngokuvamile kwenzeka emavikini ambalwa. Uma udinga ukucutshungulwa kwe-cataracts kuwo womabili amehlo, udokotela wakho uzohlela ukucutshungulwa ukususa i-cataract elinye amehlo ngemva kokuba uphulukile ekucutshungulweni lokuqala.

Thatha ukubona kwakho, isibonelo. Ungalwa nalo, kodwa ngemva kweminyaka engama-40, umbhalo omncane kwimenyu yendawo yokudlela uba nzima ukufunda. Njengoba uqhubeka ukhula, i-cataracts ingakha. Kepha manje, odokotela bafaka ama-lenses angalungisa lezi zinto nokuningi. Nansi into yakamuva evela eMayo Clinic. U-Edyth Taylor une-cataract surgery. Ukubona kwakhe kunjalo kangangokuthi kunzima kuye ukufunda izinombolo ezikhathini. U-Edyth Taylor, isiguli sokucutshungulwa kwe-cataracts: Ngingaqagela. Cishe ngemuva kwesikhathi esingu-1:00. UDharmendra Patel, M.D.—Mayo Clinic ophthalmology: Kepha ku-hazy? U-Edyth Taylor: Kepha ku-hazy. UDharmendra Patel, M.D.: Futhi lokhu kucace kakhulu? U-Edyth Taylor: Oh yebo. Lokho kucace kangangokuthi. UDharmendra Patel, M.D.: Kulungile. Kuhle, sizama ukuyilinganisa ukuze ukubona kwakho kufane kuwo womabili amehlo. Vivien Williams: U-Edyth usevele enze olunye uhlangothi. Manje sekuyisikhathi solunye. UDkt. Dharmendra Patel uthi ama-lenses amasha afakaza azoqeda ubukhulu obubangelwa yi-cataract, futhi azoqeda okuningi. UDharmendra Patel, M.D.: Ama-implants amasha atholakalayo, anika amandla amaningi. Ngakho-ke, uzothola ukulungiswa kokubona okude, okufana ne-LASIK, kepha uthola futhi ukulungiswa kokubona okusedlule noma ukufunda, futhi lokho kuyinto ehlukile kulezi zinto. Vivien Williams: Omunye isiguli, uJoyce Wisby, uthole ama-intraocular implants amasha ezinyangeni ezimbalwa ezedlule. UJoyce Wisby: Umsebenzi wami weqhubeka ekhuluma nami, 'Udinga ukwenza lokhu, awukwazi ukubona.' Vivien Williams: UJoyce uthi, ngemva kokuphila kokubona okubi okwenziwe kubi yi-cataracts, ekugcineni angabona umbhalo omncane ngaphandle kwama-eyeglasses noma ama-contact lenses. UJoyce Wisby: Uma izinombolo zincinyane kakhulu, kufanele ngiyocela usizo noma ngisebenzise i-magnifying glass ngisho nama-eyeglasses ami. Manje ngingafunda konke futhi wonke umuntu uza kimi futhi ucela ukuba ngibasize ngezinombolo. Vivien Williams: Ngesikhathi senqubo, uDkt. Patel uthambisa iso ngamaconsi. Bese, ngokusika okuncane e-cornea, ukhumula i-lens nge-cataract. Okulandelayo, ufake i-implant, evula endaweni. U-Edyth usanda kuphuma ekucutshungulweni. U-Edyth Taylor: Ngibona iwashi. Vivien Williams: Ukusebenza kwemizuzu engama-15 kokubona okuhle impilo yonke. UDkt. Patel uthi la ma-lenses asebenziswa kakhulu kubantu abane-cataracts, kepha abantu abasebancane abafuna ukulungiswa kokubona okude bangazuza futhi. Nge-Medical Edge, nginguVivien Williams. Yebo, Izingane Nezinsana Zithola I-Cataracts, Futhi Dlala Dlala Buyela kuvidiyo 00:00 Dlala Sesha imizuzwana eyi-10 emuva Sesha imizuzwana eyi-10 phambili 00:00 / 00:00 Thulisa Izilungiselelo Isithombe esisesithombeni Isikrini esigcwele Khombisa umbhalo wevidiyo Yebo, Izingane Nezinsana Zithola I-Cataracts, Futhi Sawubona. Igama lami linguEric Bothun. Ngingumhlinzeki wezokwelapha wamehlo ezinganeni eMayo Clinic eRochester, eMinnesota, enakekela izingane zazo zonke izinsuku nezifo zamehlo. Izikhathi eziningi, izingane zidinga nje ama-eyeglasses ukuqondisa amehlo azo, kepha abanye banezimo ezibuhlungu zamehlo. Ezinye zezinto ezijabulisayo kakhulu neziphezulu zomsebenzi wami ziye zafika ekuxilongeni, ucwaningo nokuphatha i-cataracts yabantwana. Yebo, izingane nezinsana zithola i-cataracts, futhi—kungaba yisifo esiyinkimbinkimbi se-genetic, ukulimala kwe-firecracker engwaneni endala, noma isifo sokuzalwa esitheni elisha. I-Cataracts ingase ihlanganise ukubona kwezingane kakhulu. Futhi njengoba ukuthuthukiswa kokubona ebuchosheni kuthatha iminyaka ukuyihlela, ukuba ne-cataract ngisho nesikhathi esifushane kuzoba nethonya lokuphila konke. Lapha eMayo Clinic, ngifuna ukuxilonga i-cataracts yabantwana ngokushesha—ngethemba ngisho kuleyo ntombazane entsha—futhi kunqume uhlelo lokusebenza olufanele nohlelo lokwelapha. Ukunakekela lezi zingane ngokuvamile kuhilela ukucutshungulwa okunzima kwe-cataracts, ngisho nangezincane kakhulu, nendlela yeqembu ekuvuseleleni nemindeni iminyaka njengoba zikhula. Konke kuqala ngokuqonda nokuqondisa izinkinga ezihlukile zomzimba noma amehlo nezimo ezihlobene njenge-glaucoma. Izikhathi eziningi, ngihlanganisa iqembu lochwepheshe lokusiza ezinhlangothini ezihlukahlukene zalowo mncele. Lokhu yisibonelo sokucutshungulwa okunzima kwe-cataract yabantwana. Izici zamehlo kule simo esisodwa zihlanganisa iso elincane ngokungavamile, ukuba nobukhulu obungavamile be-iris kanye ne-cataract efana ne-membranous nge-vessel stalk ehlanganisa leyo cataract emuva kweso. Uyakwazi ukubona leyo stalk kule vidiyo yokucutshungulwa. Amehlo anjalo ngokuvamile anampumelelo engcono ngoba abamba ingozi enkulu ye-glaucoma ne-retinal detachment. Ama-lenses e-intraocular ajwayelekile ngokuvamile awukhetho, futhi ngakho-ke, ama-contact lenses ngokuvamile asebenziswa ukulungisa ukubona ngemuva kokucutshungulwa. Kepha okubaluleke kakhulu ukunika ingane umbono oqondile ezweni. Ngihlala ngiqhathanisa i-lens e-hazy ne-chocolate M & M candy. Futhi ukucutshungulwa kwami kwe-cataract kuhilela ukuvula leyo shell ye-candy, ukususa ngokucophelela i-chocolate nokufaka i-lens entsha ekhethekile kuleyo shell ye-candy esele. Lapho, leyo lens yemvelo ihloniphekile ukunikeza ubuqili emehlweni nengane, impilo yonke. Kunezinkinga ezihlukile kweminye imibono nakweminye izingane. Ngiyajabula ukulungiselela izinketho ezaziwayo zokwelapha nokuhlinzwa ngenye ingane, ukuvakasha ngokuvakasha, njengoba zikhula. Futhi ngocwaningo nokufundisa, ngiyaqhubeka ngithola izindlela ezinhle zokusiza lezi zingane ezine-cataracts. Lokhu yisibonelo sendlela esanda kuthuthukiswa yokucutshungulwa kwe-cataract yabantwana engwaneni eneminyaka eyi-9 kuya kweminyaka emibili. Lapha, i-capsule ye-cataract ivuliwe ngesixhobo esikhethekile se-vitrector. Kunezindlela ezihlukahlukene, kuye ngokwakheka nobudala bengane, ukwenza lokhu. Okuqukethwe kwe-lens, okungase kuhluke ekuqineni nasekuqineni, kuususwa ngokuphelele. Futhi lokhu kushiya leyo nqobo yemvelo yekhapsili endaweni ngemuva kwe-iris yokufakwa kwe-lens yemvelo nokuzinza isikhathi eside. Amanye amehlo awakwazi ukubamba i-lens ejwayelekile endaweni evamile. Ngiye ngaba neqhaza ekufundeni ukuklama okusha kwe-lens okuhlanganisa nje i-lens yemvelo eceleni kwe-iris. Le ndlela ifanele kuphela kwamehlo athile kepha iye yaba ithuluzi elibalulekile lokuvuselela ukubona iziguli ezikhethekile. Ngenkonzo yami nokunakekelwa okuhlangene eMayo Clinic, sinikezela imiphumela yekhwalithi ye-cataracts yabantwana. Izithombe zangaphambi nangemva zihlaba umxhwele. Kepha imizwa yangempela enhle nobusiso bangempela kukubuka amehlo ephulukisa nokubona kuphuculwa njengoba izingane zikhula zibe ngabantu abaphelele. Uma wazi umuntu onecataract yabantwana—noma isimo esimbeka engozini yokuba nayo—sicela uze eqenjini lethu eMayo Clinic. Ulwazi Olwengeziwe Ukuhlinzwa kwe-cataracts Cela i-aphoyintimenti
