Ingabe udokotela wakho ukutshelile ukuthi unesifo esibizwa ngokuthi i-Keratoconus, esibangela ukuba i-cornea ibe mncane? Noma ingabe ukutshelile ngokwelashwa okubizwa ngokuthi i-Corneal Cross-Linking, noma i-CXL? Ungase wesabe kancane uma uzwa igama. Kodwa asikho isizathu sokwesaba. Empeleni lokhu kuyindlela yokwelapha ebaluleke kakhulu futhi ephumelelayo yokuvikela umbono wakho. Ake sixoxe ngakho konke kalula namuhla.
Kuyini ngempela i-Corneal Cross-Linking (CXL)?
Kalula nje, i-Corneal Cross-Linking (CXL) iyindlela yokwelapha encane eqinisa futhi iqinise i-cornea, ungqimba oluncane nolubonakalayo ngaphambili kweso lakho.
Cabanga ngeso lakho njengekhamera. I-cornea yeso lethu isebenza njengelensi yaleyo khamera. Ukukhanya kungena esweni ngale ndlela. Ngakho-ke, ukuma okufanele kwale cornea kubalulekile ukuze ubone kahle.
Ezimweni ezifana neKeratoconus, i-cornea iyancipha kancane kancane, iba buthaka, futhi iqhume iye phambili ibe yisimo esimise okwekhoni. Ifana nebhola eliyindilinga eliqhuma endaweni eyodwa uma lishaywa. Lokhu sikubiza ngokuthi i-corneal ectasia. Lokhu kuyinto ekhula kancane kancane ngokuhamba kwesikhathi. Njengoba lesi simo sishintsha, umbono wakho uqala ukufiphala kancane kancane futhi ubonakale unwebekile (astigmatism).
Ukwelashwa kwe-CXL kuvimbela lokhu kuncipha nokuphuma. Lokhu kungavimba i-cornea yakho ukuthi ingabi buthaka kakhulu futhi kuvimbele ukulimala kombono unomphela.
Isebenza kanjani?
I-cornea yethu yakhiwe ngemicu yamaprotheni ebizwa ngokuthi i-collagen. Lezi zifana nezintambo ezincane ezixhunywe ndawonye, zisakazeka njenge-mesh, zinikeza i-cornea amandla ayo. Le nqubo yale micu ehlangana ndawonye ibizwa ngokuthi "ukuxhumanisa okuwela phansi."
Ngesikhathi se-CXL, udokotela wakho usebenzisa ukukhanya okukhethekile kwe-UV kanye namaconsi amehlo aqukethe i-vitamin B2 ebizwa ngokuthi i-riboflavin. Uma lokhu kokubili kuhlanganiswa, kwakheka izibopho ezintsha neziqinile phakathi kwemicu ye-collagen ku-cornea. Kufana nokuthi imicu ye-mesh ebuthakathaka iyasontwa ndawonye futhi iqiniswe. Lokhu kumisa ukuncipha kanye nokuphuma kwe-cornea ngokuphelele.
Ubani ofanele lolu hlobo lokwelashwa? Futhi ubani ofanele lona?
Uma udokotela wakho ethola ukuthi ukuncipha kwe-cornea yakho kubangela ukulahlekelwa umbono unomphela, angase akuncome lokhu kwelashwa. Ake sibheke ithebula elingezansi ukuze sibone ukuthi lokhu kufanele nini nokuthi akufanelekile nini.
| Izimo lapho ukwelashwa kwe-CXL kunconywa khona | Amacala lapho ukwelashwa kwe-CXL kungase kungafaneleki |
|---|---|
| I-Keratoconus: Isimo esivame kakhulu lapho i-cornea iqhuma ibe yisimo sekhoni. | Uma i-cornea inciphile kakhulu. |
| Ukuwohloka kwe-pellucid marginal: Isimo lapho ingxenye engezansi ye-cornea iba buthakathaka khona. | Uma kukhona izibazi ezinkulu noma ukuvuleka kwe-cornea. |
| Ukonakala kwe-Terrien marginal: Isimo lapho izingxenye ezingaphandle kwe-cornea zincipha khona. | Uma uke waba nokutheleleka kwe-herpes yamehlo ngaphambilini. |
| I-ectasia yangemva kokuhlinzwa: Ubuthakathaka be-cornea ngemva kokuhlinzwa okufana ne-LASIK kanye ne-PRK. | Uma unezifo ezibangelwa amasosha omzimba . |
Ingabe lokhu kuhlinzwa? Kuyini i-Epi-off?
Yebo, i-CXL empeleni iwukuhlinzwa kwamehlo okuncane ngoba kwenziwa udokotela wamehlo. Kodwa ungakhathazeki, akuyona i-incision enkulu.
Ingxenye yokuhlinzwa kuphela yalokhu ukususwa kwengqimba encane phezu kwe-cornea, ebizwa ngokuthi i-epithelium. Kufana nengqimba encane phezu kwesikhumba sethu. Iyasuswa ukuze kuvunyelwe umuthi we-riboflavin esiwusebenzisayo ukuthi umunceke ezingqimbeni ezijulile ze-cornea. Le ndlela ibizwa ngokuthi "i-Epi-off" (i-epithelium-off). Le ndlela okwamanje ivunyelwe futhi iphumelela kakhulu emhlabeni.
Ingabe ngidinga ukulungiselela ngaphambi kokwelashwa?
Lena akuyona inqubo yokulaliswa esibhedlela. Lokhu kusho ukuthi ungaya ekhaya ngalolo suku ngemuva kokwelashwa. Akukho ukulungiselela okukhethekile okudingekayo. Kodwa-ke, njengoba ungeke ukwazi ukushayela ngemuva kokwelashwa, kubalulekile ukuthi ube nomuntu ozokuthatha akuyise ekhaya.
Kwenzekani ngesikhathi sokwelashwa?
Ukwelashwa konke kuthatha cishe imizuzu engama-60.Kuleli qophelo, ulele embhedeni. Udokotela uzokwenza lezi zinyathelo ngokulandelana:
1. Ukuqeda izinhlungu emehlweni: Okokuqala, amaconsi amehlo abulala izinhlungu afakwa esweni ukuze lingazizwa ubuhlungu.
2. Ukususwa kwe-epithelium: Okulandelayo, ungqimba oluphezulu lwe-cornea, i-epithelium, lususwa ngobunono kakhulu.
3. Ukusebenzisa umuthi: Okulandelayo, kufakwa ithonsi leso eliphuzi elibizwa ngokuthi i-riboflavin (i-vitamin B2) esweni bese lishiywa cishe imizuzu engama-30 ukuze limunce kahle.
4. Ukukhanya kwe-UV: Ngemuva kwalokho, ukukhanya okukhethekile kwe-UV kuqondiswa ku-cornea yakho cishe imizuzu engama-30. Yilapho kwenzeka khona umlingo, oqinisa izibopho ze-collagen.
5. Isinyathelo sokugcina: Ekugcineni, kusetshenziswa ama-antibiotic ukuvimbela ukutheleleka, amaconsi amehlo e-steroid asetshenziswa ukunciphisa ukuvuvukala, kanye nelensi yokuxhumana yesikhashana eboshwe ngebhandeji isetshenziswa ukuvikela iso.
Yilokho kuphela. Ngemuva kwalokho ungaya ekhaya.
Yiziphi izinzuzo nezingozi zalokhu?
Inzuzo enkulu yalokhu kwelashwa ukuthi ukuphela kokwelashwa okutholakalayo okwamanje okungamisa ukuncipha nokuvela kwe-cornea. Lokhu kuzovimba ukubona kwakho ukuthi kungaboni kahle. Kungakuvimbela futhi ukuthi uhlinzwe kakhulu, njengokufakelwa i-cornea, kamuva.
Ucwaningo luthole ukuthi izinga lempumelelo yokwelashwa kwe-Corneal Cross-Linking, ikakhulukazi esimweni i-Keratoconus, liphezulu ngamaphesenti angama-95.
Vele, njenganoma yikuphi ukwelashwa kwezokwelapha, kunezingozi ezincane kakhulu. Kodwa kubalulekile ukukhumbula ukuthi lezi azivamile .
- Ukutheleleka.
- Izibazi.
- Umbono ofiphele unomphela (umswakama we-cornea).
Udokotela wakho uzokhuluma nawe ngalezi zinto.
Sinjani isikhathi sokululama ngemva kokwelashwa?
Isikhathi sokululama ngemva kokwelashwa sidinga isineke esincane.
Okokuqala, kuzodingeka ugqoke ilensi yokuxhumana eboshwe ngebhandeji cishe isonto lonke . Lesi yisikhathi sokuba ungqimba lwe-epithelium esilususile luphinde lukhule. Phakathi nalesi sikhathi, kuzodingeka futhi usebenzise amaconsi amehlo e-steroid azonikezwa udokotela wakho.
Ubuhlungu: Ngemva kokwelashwa, ungase uzwe ubuhlungu noma ukushisa emehlweni akho. Abanye abantu bangase bakuzwe kakhulu. Udokotela wakho uzokunika amaconsi amehlo aqeda ubuhlungu ngalokhu. Uma ubuhlungu bungapheli ngisho nangemva kokusebenzisa le mithi, ungesabi ukutshela udokotela wakho.
Umbono: Into ebaluleke kakhulu ukuthi ezinsukwini zokuqala ngemva kokwelashwa, umbono wakho uzobonakala ungacacile kakhulu kunangaphambili.Lokhu kubizwa ngokuthi i-cornea haze. Lokhu kuvamile, ungakhathazeki ngakho. Umbono wakho uzoqala ukucaca kancane kancane.
Ithebula elingezansi libala izinto ongase ubhekane nazo ngesikhathi sokululama.
| Izimpawu ezivamile ezingase zivele ngesikhathi sokululama | |
|---|---|
| Ukuluma okuncane noma ukushisa esweni | Ukuzwela kokukhanya |
| Ukuzizwa sengathi kukhona okunamathele esweni | Iso elomile |
| Umbono ofiphele | Ukuvuvukala kwe-cornea |
Kungathatha cishe izinyanga ezi-2-3 ukuthi umbono wakho uzinze ngokuphelele. Ngemva kwalokho, kuzodingeka usebenzise isethi entsha yezibuko noma ama-contact lens.
Kunini lapho udinga ukukhuluma nodokotela?
Uma ubona ushintsho oluzumayo embonweni wakho ngesikhathi sokululama kwakho (isib., ukufiphala okukhulu okungazelelwe, ukubona amabala amnyama) noma uma ubuhlungu bungalawulwa yimithi udokotela wakho akunike yona, yazisa udokotela wakho ngokushesha.
Umlayezo Wokuya Nawe Ekhaya
- I-Corneal Cross-Linking (CXL) iyindlela yokwelapha ephumelela kakhulu evimba ukuncipha nokuphuma kwe-cornea futhi iyiqinise ezimweni ezifana ne-Keratoconus.
- Lokhu kuyindlela yokwelapha encane, engekho ekhaya esebenzisa amaconsi amehlo e-riboflavin (i-vitamin B2) kanye nokukhanya kwe-UV.
- Kuvamile ukuba nombono ofiphele ezigabeni zokuqala ngemva kokwelashwa. Kungathatha izinyanga eziningana ukuze ukululama okuphelele kanye nombono kuzinzile.
- Lokhu kwelashwa kungavimbela ukulimala okukhulu kwamehlo kanye nokuhlinzwa okukhulu esikhathini esizayo.
- Uma unenkinga noma ungaqiniseki ngokuthile, khuluma nodokotela wakho wamehlo njalo. Ungesabi ukubuza imibuzo.
