Amalensi okuxhumana e-Scleral angase abe ikhambi lamehlo elomile elingcono kakhulu ongakaze uzwe ngalo.

Uma uye wagwema ukuxhumana namalensi esikhathini esidlule noma uhlushwa isifo samehlo esomile, ama-scleral lens angaba yisixazululo.Uma ungakaze uzwe ngalawa ma-lens akhethekile, awuwedwa.Amalensi okuxhumana e-Scleral avame ukusetshenziswa abantu abanama-cornea angalingani noma iwindi elicacile langaphambili leso, njengalabo abane-keratoconus.

Kodwa uJohn A. Moran Eye Centre Xhumana Nochwepheshe Welensi uDavid Meyer, OD, FAAO, uyachaza ukuthi bangaba inketho enhle:
Eqanjwe nge-sclera, ingxenye emhlophe yeso, amalensi makhulu kunozakwabo abaqinile.
“Lawa ma-lens akhethekile agqokwa ku-sclera futhi akhululeke kakhudlwana kunamalensi aqinile egesi angena emlonyeni agqokwa kuma-cornea azwelayo,” kuchaza uMeyer.“Ngenxa yalokhu, ama-scleral lens awasuki njengamanye amalensi.Zingena kahle esweni futhi zigcina uthuli noma imfucumfucu ingangeni emehlweni.”
Enye inzuzo: isikhala phakathi kwengemuva le-lens kanye nobuso be-cornea sigcwele saline ngaphambi kokuba sibekwe esweni.Lolu ketshezi luhlala lungemuva kwamalensi, lunikeza ukunethezeka kosuku lonke kulabo abanamehlo omile kakhulu.
"Lapho sithuthukisa ilensi ye-scleral, sacacisa ijika elithile lokulawula ukujula komgodi oketshezi ukuze kuthuthukiswe umbono nokunethezeka," kusho uMeyer.“Sineziguli eziningi ezigqoka i-sclera kuphela ngoba zinamehlo ome kakhulu.Ngenxa yokuthi zisebenza “njengezingubo eziwuketshezi,” zingase zithuthukise izimpawu nezimpawu zamehlo omile aphakathi nendawo ukuya komile.
Ochwepheshe bagcizelela ukuthi ama-contact lens ayimishini yezokwelapha egqokwa emehlweni futhi kufanele ikhethwe ngamunye esigulini ngasinye.

"Kunamashumi ezinkulungwane zezinhlanganisela zobubanzi, i-curvature, impahla, njll. ezingathinta ukulingana kwe-lens esweni," kusho uMeyer.“Kudingeka sihlole i-physiology yamehlo akho kanye nokubona okudingekayo ukuze sinqume ukuthi yimaphi amalensi akulungele.Abafake amalensi okuxhumana badinga ukunakekela okwengeziwe ukuze bagcine amehlo abo enempilo.Kungakho sincoma ukuthi ochwepheshe be-lens basebenzele iziguli ezinjalo, ukuhlolwa kwamehlo minyaka yonke.”
