Ngaba unxiba iilensi zokunxibelelana? Okanye ungumntu onxiba iiglasi ngenxa yokungaboni kakuhle ? Sonke siyazi ukuba zixhaphake kangakanani ezi glasi. Kodwa ngamanye amaxesha, kukho iingxaki zamehlo ezinzima ngakumbi ezingenakulungiswa ngeeglasi eziqhelekileyo okanye iilensi zokunxibelelana ezithambileyo esizaziyo sonke. Namhlanje sithetha ngohlobo olwahlukileyo kancinci lwelensi oluza kunceda kwiimeko ezikhethekileyo ezinjalo. Ezi zibizwa ngokuba yiScleral Lenses.
Ngamafutshane, zithini iilensi ze-scleral?
Iilensi zeScleral nazo luhlobo lwelensi yokunxibelelana enxitywa elisweni. Nangona kunjalo, ezi zinkulu kancinci kuneelensi zokunxibelelana esihlala sizibona. Cinga ngale ndlela, ngelixa ilensi yokunxibelelana eqhelekileyo ifana nesosi encinci ehlala kuphela kwi -cornea yeliso, ilensi yescleral ifana nesosi enkulu egubungela inxalenye emhlophe yeliso (i-sclera). Yiyo loo nto ibizwa ngokuba yi-'Scleral'.
Ezi zenziwe ngezinto ezibizwa ngokuba yi -'Rigid Gas-Permeable' (RGP) . Oku kuthetha ukuba ezi lensi zityebile kancinci, azigobi lula xa uzibamba, kwaye azitshintshi imo. Kodwa okukwakhethekileyo kukuba igesi yeoksijini inokungena elisweni ngezi lensi. Oku kubaluleke kakhulu kwimpilo yeliso.
Eyona nto ibalulekileyo apha kukuba le lensi ayichukumisi ngqo i-cornea. Kudalwa indawo encinci phakathi kwelensi kunye ne-cornea. Njengebhulorho encinci. Xa sibeka le lensi esweni, le ndawo izaliswe lulwelo olukhethekileyo (isisombululo se-saline ). Emva koko i-cornea yeliso ihlala imanzi kwaye ikhuselekile.
Kutheni kusetyenziswa iilensi ze-scleral? Ngubani obaluleke kakhulu kuzo?
Iingcali zamehlo zicebisa ezi lensi ze-scleral kwizifo ezahlukeneyo zamehlo kunye neemeko ezahlukeneyo. Zinokuba luncedo olukhulu, ingakumbi kwabo banengxaki yokufumana umbono ocacileyo ngeeglasi okanye iilensi eziqhelekileyo.
Jonga itheyibhile engezantsi ukuze ubone ukuba zeziphi iimeko ezisetyenziswa kakhulu.
| Imeko/Isizathu | Ingcaciso elula |
|---|---|
| Izifo ze-cornea | Ingakumbi iimeko ezifana neKeratoconus , apho i-cornea yeliso ivuvukala phambili ngendlela efana nekhowuni, nto leyo ebangela ukubona okufipheleyo. |
| Iimpazamo ezinkulu zokuchasana nokukhanya | Kwabo banengxaki enkulu yokubona abangenakulungiseka ngeeglasi okanye iilensi eziqhelekileyo. |
| Iliso elomileyo kakhulu | Ulwelo oluphakathi kwelensi neliso lugcina iliso limanzi kwaye luthintela umonakalo ekubeni wome. |
| Amanxeba okanye umonakalo kwi-cornea | Xa umphezulu we-cornea ungaba mhle emva kokwenzakala kweliso okanye usulelo, ukuze ulusulule kwaye ubone ngokucacileyo. |
| Ezinye iimeko zonyango ezintsonkothileyo | Ukulawula umonakalo kumphezulu weliso obangelwa zizifo ezifana neGraft vs. Host Disease (GvHD) kunye neStevens-Johnson Syndrome . |
Ziziphi iingenelo zokusebenzisa ezi lensi?
Iilensi ze-scleral zinezibonelelo ezininzi ezizenza zahluke kwezinye iintlobo zeelensi.
- Umbono ocacileyo nobukhali kakhulu: Abantu abaninzi bathi umbono wabo ucacile kwaye ubukhali kakhulu xa benxibe ezi lensi. Abanye bathi kuvakala ngathi bajonge umfanekiso ocacileyo (HD).
- Aziwi lula: Ngenxa yokuba ezi lensi zinkulu kwaye imiphetho yazo ihlala phantsi kwejwabu leso, azishukumi okanye ziwe njengeelensi eziqhelekileyo. Oku kuzenza zikhululeke kakhulu, kwanakwabo badlala imidlalo.
- Ukhuseleko olukhulu lwamehlo: Ekubeni ilensi igubungela indawo enkulu, uthuli nezinye izinto azingeni kakhulu elisweni. Ikwabonelela ngokhuseleko olungcono kwi-cornea eyonakeleyo.
- Ukugcina iliso limanzi: Njengoko besitshilo ngaphambili, ulwelo olungaphakathi kwilensi lugcina iliso limanzi. Oku kuluncedo kakhulu kwabo banesifo samehlo esomileyo.
- Kwanotyando oluthile lunokurhoxiswa: umzekelo, iKeratoconusKwiimeko ezinzima kakhulu, utyando lunokufuneka. Nangona kunjalo, iilensi ze-scleral ngamanye amaxesha zinokuthintela okanye zibambezele isidingo sotyando .
Ngaba kukho iingxaki? Zeziphi iingxaki ekufuneka uzazi?
Njengayo yonke into, ezi lensi zineengxaki zazo kunye nemingeni, kodwa uninzi lwazo luyakwazi ukulawuleka.
- Kuthatha ixesha ukuqhela: Ukufaka, ukususa, nokucoca ezi lensi kuthatha ixesha ukuziqhela. Kungavakala kungaqhelekanga kwiintsuku zokuqala ezimbalwa. Ngoko ugqirha wakho uza kukuxelela ukuba uzinxibe iiyure ezimbalwa ekuqaleni uze wongeze ixesha kancinci kancinci.
- Ibiza kancinci: Ngenxa yokuba ezi ziilensi ezikhethekileyo kwaye kufuneka zenziwe zilingane nomntu ngamnye, zibiza kancinci kuneelensi eziqhelekileyo zokunxibelelana.
- Ukugcinwa kuyimfuneko: Xa zinxitywa imini yonke, amasuntswana amancinci othuli nothuli anokuqokelelana kulwelo olungaphakathi kwilensi. Oku kunokubangela ukufiphala okuncinci kombono. Ke ngoko, abantu abaninzi kufuneka basuse, bacoce, baze baphinde bafake iilensi zabo ubuncinane kanye ngemini.
- Kungathatha iinzame ezininzi ukuze ufumane ukulingana okufanelekileyo: Usenokungakwazi ukufumana ukulingana okufanelekileyo kwangoko. Kungathatha iinzame ezimbini okanye ezintathu ukuze ufumane ukulingana okufanelekileyo. Oku kuqhelekile, ngoko ungakhathazeki.
Uzifaka njani ezi lensi uze uzikhuphe?
