Abafundi bezikole zamabanga aphansi nezamabanga aphezulu bazoqala amaholide abo ehlobo esikhathini esingangesonto.Izinkinga zokubona zezingane zizophinde zibe intokozo yabazali.
Eminyakeni yamuva, phakathi kwezindlela eziningi zokuvimbela nokulawula i-myopia, ama-lens defocusing, anganciphisa ukuthuthukiswa kwe-myopia, aye athandwa kakhulu phakathi kwabazali.
Ngakho-ke, ungakhetha kanjani ama-lens we-defocusing?Ingabe zifanelekile?Yimaphi amaphuzu okufanele uwaqaphele ku-Optometry?Ngemva kokufunda okuqukethwe okulandelayo, ngicabanga ukuthi abazali bazoqonda kangcono.
Ayini ama-defocusing lens?
Ngokuvamile, ama-defocusing lens angama-microstructured spectacle lens, aklanyelwe ukuqukatha indawo ephakathi nendawo kanye ne-microstructured area, eyinkimbinkimbi kakhulu ngokwemingcele ye-optical futhi efuna kakhulu ngokufaneleka kunezibuko ezivamile.
Ngokucacile, indawo emaphakathi isetshenziselwa ukulungisa i-myopia ukuze kuqinisekiswe "ukubona okucacile", kuyilapho indawo ezungezile iklanyelwe ukukhiqiza i-myopic defocus ngokusebenzisa idizayini ekhethekile yokubona.Izimpawu ze-myopic defocus ezikhiqizwa kulezi zindawo zingavimbela ukukhula kwe-eksisi yamehlo, ngaleyo ndlela zehlise ukuqhubekela phambili kwe-myopia.
Uyini umehluko phakathi kwamalensi ajwayelekile namalensi asusa ukugxila?
Amalensi avamile e-monofocal agxilisa isithombe sombono omaphakathi ku-retina futhi angakwazi ukulungisa kuphela ukubona, avumele umuntu ukuthi abone ngokucacile lapho ewagqokile;
Amalensi asusa ukugxila awagxili kuphela isithombe sombono omaphakathi ku-retina ukuze asivumele ukuthi sibone ngokucacile kodwa futhi agxilise indawo ezungezile ku-retina noma phambi kwe-retina, okwenza i-peripheral myopic defocus ebambezela ukukhula kwe-myopia.
Ubani ongasebenzisa amalensi asusa ukugxila?
1. I-Myopia engeqi amadigri angu-1000, i-astigmatism engeqi amadigri angu-400.
2. Izingane kanye nentsha umbono wayo ujula ngokushesha okukhulu futhi enezidingo eziphuthumayo zokuvimbela nokulawula i-myopia.
3. Labo abangafaneleki ukugqoka amalensi e-Ortho-K noma abangafuni ukugqoka amalensi e-Ortho-K.
Qaphela: Iziguli ezine-strabismus, ukubona okungavamile kwe-binocular, ne-anisometropia zidinga ukuhlolwa ngudokotela futhi zicabange ukuthi zifanelekile njengoba kufanele.
Kungani ukhetheukuqeda ukugxilaamalensi?
1. Amalensi angagxili ayasebenza ekulawuleni i-myopia.
2. Inqubo yokufaka ama-lens e-defocusing ilula futhi awukho umehluko omkhulu enqubweni yokuhlola kuleyo yamalensi avamile.
3. Ama-lens agxilile awaxhumani ne-cornea yeso, ngakho-ke ayikho inkinga yokutheleleka.
4. Uma kuqhathaniswa namalensi e-Ortho-K, amalensi asusa ukugxila kulula ukuwanakekela nokuwagqoka, amalensi e-Ortho-K adinga ukuwashwa futhi abulawe amagciwane ngaso sonke isikhathi lapho ekhishwa futhi efakwa futhi adinga nezixazululo zokunakekela okukhethekile ukuze awanakekele.
5. amalensi asusa ukugxila ashibhile kunamalensi e-Ortho-K.
6. Uma kuqhathaniswa namalensi e-Ortho-K, amalensi asusa ukugxila asebenza kuhlu olubanzi lwabantu.
