Namuhla, sizokhuluma ngohlobo oluhlukile kancane, olukhethekile lwe-lens olungasiza ezimweni ezinjalo. Lawa abizwa ngokuthi ama-scleral lens.
Ngakho-ke ziyini lezi lensi ze-scleral?
Kalula nje, amalensi e-scleral nawo awuhlobo lwelensi yokuxhumana egqokwa esweni. Kodwa-ke, makhulu kancane kunamalensi okuxhumana athambile esivame ukuwabona. Futhi umehluko omkhulu ukuthi awahlali ngqo engxenyeni emnyama ezwelayo yeso (i-cornea).
Cabanga ukuthi i-cornea yeso lakho ifana negquma elincane eliyindilinga. Ilensi evamile ihlala phezu kwaleli gquma. Kodwa ilensi ye-scleral ihlala phezu kwaleli gquma futhi iphumule engxenyeni emhlophe ezungezile yeso (i-sclera). Yingakho ibizwa ngokuthi ilensi "ye-scleral".
Kudalwa isikhala esincane phakathi kwale lensi ne-cornea. Lesi sikhala asishiywa nje lapho. Ngaphambi kokuba sifake le lensi esweni lakho, sigcwalisa ngesisombululo esikhethekile se-saline (i-saline engenazo izithiyo). Okwenzekayo ukuthi sonke isikhathi osigqoka, i-cornea yakho icwiliswa kulesi sixazululo. Kufana nenhlanzi encane emanzini. Lokhu kunikeza impumuzo emangalisayo, umswakama, kanye nesivikelo esweni.
Lezi zenziwe ngezinto ezikhethekile eziqinile kancane, kodwa ezivumela umoya-mpilo ukuthi udlule. Ngokwezokwelapha, lezi zilensi sizibiza ngokuthi 'i-Rigid Gas-Permeable' (RGP). Ngenxa yokuthi azishintshi isimo, zinganikeza umbono ocacile ngisho nakubantu abane-cornea engakhekile kahle.
Enye into ukuthi ngenxa yokuthi la malensi makhulu, imiphetho yawo iphansi nje kwamehlo. Ngakho-ke mancane amathuba okuthi awe kalula njengamalensi avamile, futhi mancane amathuba okuthi uthuli nezinye izinto zingene esweni.
