I-lens ye-contact ye-hybrid yinkalo ekhethekileyo yoqhagamshelwano enokuba yinto enokukhetha ngayo ukuba unganakulungele ukumbatha i-lens ezinobungqina be-gas . Ama-lens axhumene ne-hybrid azama ukunika abantu ubuqili obubonakalayo begesi ephosakeleyo engabonakaliyo kunye nentuthuzelo ye-lens ephathekayo. I-lens ye-lens hybrid iqukethe igalari eqinileyo yerhasi yokuxhamla enokubambisana kunye neengubo zangaphandle ezenziwe ngezinto eziluhlaza.
Ngubani ofuna iiLens zokuXhumana zamaHlathi?
Obuthelwano be-Hybrid alunabo bonke abantu. Abanye abantu banokuzuza kwi-design lens hybrid. Funda uluhlu olulandelayo uze ubone ukuba ngaba ungumviwa wee-lens zokuxilana.
- Ngaba unqwenela ukulungiswa kombono? Ngaba awuhlali ujabule nombono wakho olungiswe ngama-lens rhoqo?
- Ngaba unayo imali ephezulu ye- astigmatism ?
- Ukuba unemali ephezulu ye-astigmatism, ngaba ufuna ukugqoka i-lens ye-bifocal lens?
- Ingaba uvalelwa yi-keratoconus ?
- Ngaba uye waba nexinzelelo okanye i-corneal transplant kunye ne-distortion corneal?
- Ngaba unakho ukuhlinzwa ngokutsha kwaye awuyivuyo nemiphumo?
Abantu abanezinye iingxaki ezikhankanywe ngasentla banomnye uhlobo lwesitenxo okanye ukuphazamiseka. Amaxesha amaninzi le ngxaki ayilungelekanga kunye neeklasi zamehlo kunye noogqirha bazakuzama ukufaka i-lens eqinekileyo yokubambisa i-lens. I-lens elukhuni ibonisa imbonakalo engcono ngoba ibumba zonke iindawo eziphazamisayo, zilinganisa indawo entsha ebonakalayo ejongene nokukhanya.
Ngenxa yokuba i-lens encinci yothintana nayo ilula, i-astigmatism okanye ukuphazamiseka ngokukhawuleza kukhanya ngokukhawuleza ngelo lense ngenxa yokuba i-lens esithambileyo igqithise i-cornea.
Ngenxa yokuba i-lensi egxininisekayo yelenki iyinto enzima, ayinakho konke kubo bonke abantu. Abanye abantu banokuphazamiseka okukhulu kangangokuba kunzima kwigqirha labo kwamehlo ukwenzela ukuba i-lens ibekwe kakuhle ngokufanelekileyo kwi-cornea kunye nomfundi.
Ngomxholo we-lens oxhumene ne-hybrid, i-optics ekhethiweyo yelensi elukhuni inikwe i-lens eqinile. I-lens eqinekileyo igqithisa i-cornea ngoko ayiyikuxubha ngokubhekiselele kuyo, kubangela ukunganeliseki. Ingubo ephothileyo ithatha i-lens eqinile kwindawo yokuphepha ukuphazamiseka.
Ngaba Ngaba Unokugqoka iiLensi zeHybrid?
Ukuba unako ukugqoka i-lens yokuthintana rhoqo, unokuthi unxibe i-lens hybrid. Nangona kunjalo, awukwazi ukubona inzuzo enkulu ngaphandle kokuba unemiqathango ekhankanywe ngasentla. Izigulane ezigqoka ii-lens ze-hybrid zibonisa ukuba umbono wabo unzima ngakumbi kunokuba zilungiswe nge-lens elithambileyo. Ngamanye amaxesha, i-lens hybrid ayiyi kusebenza. Ngamanye amaxesha kwenzeka xa umntu enesi-astigmatism ye-lentic esikhundleni se-astigmatism. Ugqirha wakho uya kuqhuba iimvavanyo eziliqela ukuqinisekisa ukuba i-lens hybrid iya kusebenzela.
ILizwi
Abanye abantu bacinga ukuba ii-lens ze-hybride zidinga ixesha elongezelelweyo lokunyamekela nokucoca. Uninzi lwamalensi e-hybrid alula nje ukunyamekela njengama-lens oqhagamshelwano rhoqo. Ngamanye amaxesha, isisombululo esifanayo sinokusetyenziswa. Nangona kunjalo, into enye ekufuneka uyihlawule ngokukodwa inxalenye yesikhungo se-lens. Ngenxa yokuba inxalenye yesikhungo iyanzima, inokuphulwa ukuba ingcinezelo eninzi isetyenziswe kuyo ngelixa uhlamba okanye uhlambulula ilensi.
