Ngaba ugqirha wakho ukuxelele ukuba unesifo esibizwa ngokuba yiKeratoconus, esibangela ukuba i-cornea ibe buthathaka? Okanye ukuxelele ngonyango olubizwa ngokuba yiCorneal Cross-Linking, okanye iCXL? Usenokoyika kancinci xa usiva igama. Kodwa akukho sizathu sokoyika. Olu lunyango olubaluleke kakhulu nolusebenzayo lokukhusela umbono wakho. Makhe sithethe ngayo yonke into ngokulula namhlanje.
Yintoni kanye kanye iCorneal Cross-Linking (CXL)?
Ngamafutshane, iCorneal Cross-Linking (CXL) lunyango oluncinci oluqinisa kwaye luqinise i-cornea, umaleko omncinci nocacileyo ongaphambili kweliso lakho.
Cinga ngeliso lakho njengekhamera. I-cornea yeliso lethu isebenza njengelensi yaloo khamera. Ukukhanya kungena ngeli liso. Ngoko ke, imo echanekileyo yale cornea ibalulekile ukuze ubone kakuhle.
Kwiimeko ezifana neKeratoconus, i-cornea iyancipha kancinci kancinci, ibuthathaka, ize ivuthuluke iye phambili ibe yimo efana nekhowuni. Ifana nebhola engqukuva evuthulukayo kwindawo enye xa itshayiswa. Le yi-corneal ectasia esiyibiza ngokuba yi-corneal ectasia. Le yinto ekhula kancinci kancinci ngokuhamba kwexesha. Njengoko le milo itshintsha, umbono wakho uqala ukufiphala kancinci kancinci kwaye ubonakale unwebekile (astigmatism).
Unyango lwe-CXL luyayimisa le ngxaki yokuncipha nokuphuma kwayo. Oku kunokuthintela i-cornea yakho ekubeni buthathaka ngakumbi kwaye kuthintele umonakalo ongapheliyo wokubona.
Isebenza kanjani lento?
I-cornea yethu yenziwe ngeefayibha zeproteni ezibizwa ngokuba yi-collagen. Ezi zifana neentambo ezincinci ezidityanisiweyo, zisasazeka njenge-mesh, zinika i-cornea amandla ayo. Le nkqubo yezi fayibha zidibana ibizwa ngokuba yi-"cross-linking."
Ngexesha le-CXL, ugqirha wakho usebenzisa umqadi wokukhanya we-UV okhethekileyo kunye namaconsi eliso aqulethe i-vitamin B2 ebizwa ngokuba yi-riboflavin. Xa ezi zimbini zidityanisiwe, kwakheka amaqhina amatsha, aqinileyo phakathi kweefayibha ze-collagen kwi-cornea. Kufana nemisonto ye-mesh ebuthathaka ejijekileyo kunye kwaye yomelezwe. Oku kuyekisa ukuncipha kunye nokuphuma kwe-cornea ngokupheleleyo.
Ngubani olu nyango lufanelekileyo? Kwaye ngubani olungafanelekanga?
Ukuba ugqirha wakho ufumanisa ukuba ukubhitya kwe-cornea yakho kubangela ukulahleka kokubona okungapheliyo, angacebisa olu nyango. Makhe sijonge itheyibhile engezantsi ukuze sibone ukuba oku kufanelekile na ukuba akufanelekanga.
| Iimeko apho unyango lwe-CXL lucetyiswa khona | Amatyala apho unyango lwe-CXL lusenokungafaneleki |
|---|---|
| I-Keratoconus: Eyona meko ixhaphakileyo apho i-cornea idumba ibe yimo yekhowuni. | Ukuba i-cornea inciphile kakhulu. |
| Ukonakala kwe-pellucid marginal: Imeko apho inxalenye esezantsi ye-cornea incipha khona. | Ukuba kukho amanxeba okanye ukuvuleka okukhulu kwe-cornea. |
| Ukonakala kwe-Terrien marginal: Imeko apho iindawo ezingaphandle kwe-cornea zincipha khona. | Ukuba ukhe wanesifo se-herpes emehlweni ngaphambili. |
| I-ectasia emva kotyando: Ukubuthathaka kwe-cornea emva kotyando olufana ne-LASIK kunye ne-PRK. | Ukuba unezifo ezibangelwa kukuzikhusela komzimba . |
Ingaba olu lutyando? Yintoni i-Epi-off?
Ewe, i-CXL ngokwenyani lutyando oluncinci lwamehlo kuba lwenziwa yingcali yamehlo. Kodwa ungakhathazeki, ayilotyando olukhulu.
Inxalenye yotyando kuphela koku kukususa umaleko omncinci phezu kwe-cornea, ebizwa ngokuba yi-epithelium. Ifana nomaleko omncinci phezu kolusu lwethu. Isuswa ukuze amayeza e-riboflavin esiwasebenzisayo angene kwiingqimba ezinzulu ze-cornea. Le ndlela ibizwa ngokuba yi-"Epi-off" (epithelium-off). Le ndlela okwangoku yeyona ivunyiweyo kwaye iphumelele kakhulu kwihlabathi liphela.
Ngaba kufuneka ndilungiselele ngaphambi konyango?
Le ayisiyonkqubo yokunyanga ngaphandle kwesibhedlele. Oku kuthetha ukuba ungagoduka ngosuku olunye emva konyango. Akukho lungiselelo likhethekileyo lifunekayo. Nangona kunjalo, kuba awuyi kukwazi ukuqhuba emva konyango, kubalulekile ukuba ube nomntu oza kukusa ekhaya.
Kwenzeka ntoni ngexesha lonyango?
Lonke unyango luthatha malunga nemizuzu engama-60.Okwangoku, ulele ebhedini. Ugqirha uza kwenza la manyathelo ngokulandelelana:
1. Ukuthintela amehlo ukuba angasebenzi kakuhle: Okokuqala, amaconsi eliso anokubulala iintlungu asetyenziswa esweni ukuze angaziva ntlungu.
2. Ukususwa kwe-epithelium: Okulandelayo, umaleko ongaphezulu we-cornea, i-epithelium, ususwa ngobuchule kakhulu.
3. Ukusebenzisa iyeza: Okulandelayo, faka amathontsi atyheli emehlweni abizwa ngokuba yi-riboflavin (ivithamini B2) esweni uze uwashiye malunga nemizuzu engama-30 ukuze afunxe kakuhle.
4. Ukukhanya kwe-UV: Emva koko, umqadi wokukhanya we-UV okhethekileyo ujoliswa kwi-cornea yakho malunga nemizuzu engama-30. Kulapho umlingo uvela khona, uqinisa ii-collagen bonds.
5. Inyathelo lokugqibela: Okokugqibela, kusetyenziswa amayeza okubulala iintsholongwane ukuthintela usulelo, amaconsi e-steroid emehlweni asetyenziselwa ukunciphisa ukudumba, kwaye kusetyenziswa ilensi yokunxibelelana yebhandishi yexeshana ukukhusela iliso.
Yiloo nto kuphela. Emva koko ungagoduka.
Zithini iingenelo kunye neengozi zoku?
Eyona nzuzo inkulu yolu nyango kukuba lolona nyango lufumanekayo okwangoku olunokuthintela ukubhitya nokuphuma kwe-cornea. Oku kuya kuyithintela imbono yakho ukuba ingabi mbi. Kungakuthintela nasekubeni kufuneka wenze utyando olukhulu, njengokufakelwa i-cornea, kamva.
Uphando lufumanise ukuba izinga lempumelelo yonyango lweCorneal Cross-Linking, ingakumbi kwisifo iKeratoconus, liphezulu njenge-95%.
Kakade ke, njengakwezinye iindlela zonyango, kukho iingozi ezincinci kakhulu. Kodwa kubalulekile ukukhumbula ukuba ezi azixhaphakanga kakhulu .
- Usulelo.
- Amanxeba.
- Umbono ongapheliyo ongaboni kakuhle (inkungu ye-cornea).
Ugqirha wakho uza kuthetha nawe ngezi zinto.
Linjani ixesha lokuchacha emva konyango?
Ixesha lokuchacha emva konyango lifuna umonde omncinci.
Okokuqala, kuya kufuneka unxibe ilensi yokunxibelelana ngebhandishi kangangeveki . Eli lixesha lokuba umaleko we-epithelium esiwususileyo ukhule kwakhona. Ngeli xesha, kuya kufuneka usebenzise amaconsi amehlo e-steroid aza kucetyiswa ngugqirha wakho.
Intlungu: Emva konyango, unokufumana iintlungu okanye ukutsha emehlweni akho. Abanye abantu basenokuziva kakhulu. Ugqirha wakho uza kukunika amathontsi amehlo athomalalisa iintlungu ngenxa yoku. Ukuba iintlungu azipheli nasemva kokusebenzisa la mayeza, ungoyiki ukuxelela ugqirha wakho.
Umbono: Eyona nto ibalulekileyo kukuba kwiintsuku zokuqala emva konyango, umbono wakho uya kubonakala ungacacanga ngakumbi kunangaphambili.Oku kubizwa ngokuba yi-cornea haze. Oku kuqhelekile, ungakhathazeki ngako. Umbono wakho uza kuqala ukucaca kancinci kancinci.
Le theyibhile ingezantsi idwelisa izinto onokuhlangabezana nazo ngexesha lokuchacha.
| Iimpawu eziqhelekileyo ezinokwenzeka ngexesha lokuchacha | |
|---|---|
| Ukurhawuzelela okanye ukutsha kancinci emehlweni | Uvakalelo lokukhanya |
| Ukuziva ngathi kukho into ebambeke emehlweni | Iliso elomileyo |
| Umbono ofipheleyo | Ukudumba kwe-cornea |
Kungathatha malunga neenyanga ezi-2-3 ukuba umbono wakho uzinze ngokupheleleyo. Emva koko, kuya kufuneka usebenzise iseti entsha yeeglasi okanye iilensi zoqhagamshelwano.
Kufuneka uthethe nini nogqirha?
Ukuba ubona utshintsho olukhawulezileyo embonweni wakho ngexesha lokuchacha (umz., ukufiphala okukhulu ngequbuliso, ukubona amabala amnyama) okanye ukuba intlungu ayilawulwa ngamayeza anikwe ngugqirha wakho, yazisa ugqirha wakho ngoko nangoko.
