DMagalasi a efocus Incorporated Multiple Segments Lenses amatchedwa chifukwa pali magalasi ang'onoang'ono angapo omwe amawoneka ndi maso pamakona enaake pamwamba pa lens, omwe amagawidwa mu mawonekedwe a nsonga, ndichifukwa chake amatchedwa. Magalasi a Defocus Incorporated Multiple Segments Lenses ndi mtundu wa magalasi oletsa ndi owongolera myopia, omwe amapangidwa ndi madera awiri. Limodzi ndi dera lapakati la kuwala lomwe limagwiritsidwa ntchito kukonza zolakwika za refractive (myopia, kuwona patali ndi astigmatism), ndipo lina ndi pakati lomwe limafikira kumalire a lens. Madera ambiri a myopic defocus. Wovala akayang'ana zinthu patali zosiyanasiyana, magalasi a defocus omwe amaphatikizidwa amatha kupereka masomphenya omveka bwino komanso myopia defocus nthawi imodzi, ndipo amatha kupewa ndikuwongolera kukula kwa myopia pamene akukonza masomphenya.
Mfundo yaikulu ndikugwiritsa ntchito njira yachilengedwe yolumikizirana ndi maso - zomwe zimachitika chifukwa cha emmetropization, kuti masomphenya, kukula kwa masomphenya ndi chithunzi cha retina cha diso zikhale pafupi kwambiri ndi momwe masomphenya a emmetropic amakhudzira.
Pakadali pano, myopia yeniyeni ya achinyamata nthawi zambiri imakhala axial myopia, yomwe imayamba chifukwa cha kukula kwa axis ya diso. Chifukwa cha kutalika kwa diso, malo a chithunzicho amaonekera patsogolo pa retina. Pokonza ma lens wamba a myopia, kukonza komveka bwino kumangoyang'ana masomphenya apakati, ndipo kapangidwe ka lens palokha kamawonjezeka pang'onopang'ono kapena mosasamala kukula kwa dera lomwe lili kunja kwa kuwala kwapakati. Pambuyo pokonza, chinthu chomwecho chikhoza kuonekera pa fovea ya macula popanda vuto lililonse, kuonetsetsa kuti masomphenya ndi omveka bwino. Komabe, chinthu chomwe retina imalandira sichili mwachindunji pa retina, koma chimajambulidwa kumbuyo kwa retina. Izi zidzathandizanso ku zomwe tsopano tikuziona ngati hyperopia defocus, zomwe pakali pano zimadziwika kuti ndi chimodzi mwa zifukwa zazikulu zomwe ofufuza amapangira myopia ndikuzama. Izi zili choncho chifukwa hyperopia defocus kumbali yakumbuyo ya retina imalimbikitsa kukula kwa axis ya maso kumbali yakumbuyo, zomwe zimapangitsa kukula kwa axial ndikuzama kwambiri kwa myopia.
Lenzi yaying'ono yomwe ili m'dera la defocus idapangidwa mwapadera kuti ikhale ndi digiri yosiyana ndi lenzi imodzi yomwe ili m'dera lowongolera, zomwe zimapangitsa kuti chithunzicho chigwere patsogolo pa retina, zomwe zimapangitsa kuti myopia ichotse focus ndikupereka chizindikiro ku axis ya diso patsogolo, zomwe zimapangitsa kuti myopia ichedwetse kukula.
Ubwino:
1. Zotsatira za kulamulira kwa myopia n'zoonekeratu: zotsatira za kuchedwa pa kukula kwa digiri ya myopia ndi 59%, ndipo zotsatira za kulamulira pa kukula kwa axial ndi 60%.
2. Kuyika kosavuta: Magalasi a myopia defocus okhala ndi mfundo zambiri ndi mtundu wapadera wa lenzi imodzi yokha, ndipo kuyika kwake n'kosavuta.
3. Chitonthozo chachikulu: Magalasi a myopia defocus okhala ndi mfundo zambiri alibe malo obisika ndipo sakhudza diso la munthu. Mosiyana ndi magalasi olumikizana, omwe amakhudza cornea, sangayambitse kusasangalala.
4. Chisamaliro Chosavuta: Poyerekeza ndi magalasi ena, monga magalasi a orthokeratology, omwe amafunika kutsukidwa m'manja ndi kutsukidwa nthawi iliyonse akamachotsedwa ndi kuvala, ndipo kukonza magalasi kumafuna njira zapadera zosamalira.
5. Kuchedwa kwa myopia kuli pafupifupi 59%, ndipo kulamulira kwa kukula kwa axial kuli pafupifupi 60%.
