Ingabe ugqoka amalensi okuxhumana? Noma ungumuntu ogqoka izibuko ngenxa yokungaboni kahle ? Sonke siyazi ukuthi lezi zivamile kangakanani. Kodwa ngezinye izikhathi, kunezinkinga zamehlo eziyinkimbinkimbi kakhulu ezingenakuxazululwa ngezibuko ezivamile noma amalensi okuxhumana athambile esiwaziyo sonke. Namuhla sikhuluma ngohlobo oluhlukile kancane lwelensi olusiza ezimweni ezinjalo ezikhethekile. Lawa abizwa ngokuthi ama-Scleral Lenses.
Kalula nje, ayini amalensi e-scleral?
Amalensi e-Scleral nawo uhlobo lwelensi yokuxhumana egqokwa esweni. Kodwa-ke, lawa makhudlwana kunamalensi okuxhumana esivame ukuwabona. Cabanga ngale ndlela, kuyilapho ilensi yokuxhumana evamile ifana nesoso elincane elihlala kuphela ku -cornea yeso, ilensi ye-scleral ifana nesoso elikhulu elimboza ingxenye emhlophe yeso (i-sclera). Yingakho ibizwa ngokuthi 'i-Scleral'.
Lezi zenziwe ngezinto ezibizwa ngokuthi 'i-Rigid Gas-Permeable' (RGP) . Lokhu kusho ukuthi la malensi ajiyile kancane, awagobeki kalula uma uwabamba, futhi awashintshi ukuma kwawo. Kodwa futhi okukhethekile ukuthi igesi yomoya-mpilo ingangena esweni ngala malensi. Lokhu kubaluleke kakhulu empilweni yeso.

- Ngisho nokuhlinzwa okuthile kungahlehliswa: isibonelo, i-KeratoconusEzimweni ezimbi kakhulu, ukuhlinzwa kungadingeka. Kodwa-ke, amalensi e-scleral ngezinye izikhathi angagwema noma abambezele isidingo sokuhlinzwa .
Ingabe kukhona okungalungile? Yiziphi izinselele okufanele uziqaphele?
Njengakho konke, la malensi anezinkinga zawo kanye nezinselele, kodwa iningi lawo liyalawuleka.
- Kuthatha isikhathi ukujwayela: Ukufaka, ukususa, nokuhlanza la malensi kuthatha isikhathi ukujwayela. Kungazwakala kungavamile ezinsukwini ezimbalwa zokuqala. Ngakho udokotela wakho uzokutshela ukuthi uwagqoke amahora ambalwa ekuqaleni bese wandisa isikhathi kancane kancane.
- Kubiza kancane: Ngenxa yokuthi lawa amalensi akhethekile futhi kumele enziwe afanele umuntu ngamunye, abiza kancane kunamalensi okuxhumana avamile.
- Kudingeka ukulungiswa: Uma zigqokwa usuku lonke, izinhlayiya ezincane zokungcola nothuli zinganqwabelana oketshezini olungaphakathi kwelensi. Lokhu kungabangela ukufiphala okuncane kokubona.
