Ophunzira akusukulu za pulaimale ndi sekondale ayamba tchuthi chawo chachilimwe mkati mwa sabata.Mavuto a maso a ana adzakhalanso chidwi cha makolo.
M'zaka zaposachedwapa, mwa njira zambiri za kupewa myopia ndi kulamulira, defocusing magalasi, amene akhoza m'mbuyo chitukuko cha myopia, akhala otchuka kwambiri pakati pa makolo.
Choncho, kusankha magalasi defocusing?Kodi ndizoyenera?Ndi mfundo ziti zomwe muyenera kuziwona mu optometry?Ndikawerenga zotsatirazi, ndikuganiza kuti makolo amvetsetsa bwino.
Kodi defocusing lens ndi chiyani?
Nthawi zambiri, magalasi opumira ndi magalasi owoneka bwino a microstructured, opangidwa kuti azikhala ndi malo apakati owoneka bwino komanso malo opangidwa ndi microstructured, omwe ndi ovuta kwambiri potengera magawo owoneka bwino komanso ofunikira kwambiri pakuyenerera kuposa mawonedwe wamba.
Mwachindunji, malo apakati amagwiritsidwa ntchito kukonza myopia kuti awonetsetse "masomphenya omveka", pamene dera lozungulira limapanga kupanga myopic defocus kupyolera mu mawonekedwe apadera a kuwala.Zizindikiro za myopic defocus zomwe zimapangidwira m'maderawa zimatha kulepheretsa kukula kwa diso, motero kumachepetsa kupitirira kwa myopia.
Kodi pali kusiyana kotani pakati pa magalasi abwinobwino ndi ma lens ofooketsa?
Ma lens wamba a monofocal amayang'ana chithunzi chapakati pa retina ndipo amatha kuwongolera masomphenya, kulola munthu kuwona bwino atavala;
Magalasi osayang'ana samangoyang'ana chithunzi chapakati pa retina kuti titha kuwona bwino komanso kuyang'ana mbali zonse za retina kapena kutsogolo, ndikupanga peripheral myopic defocus yomwe imachepetsa kukula kwa myopia.
Ndani angagwiritse ntchito magalasi ofooketsa?
1. Myopia osapitirira madigiri 1000, astigmatism osapitirira madigiri 400.
2. Ana ndi achinyamata omwe masomphenya awo akukulirakulira kwambiri komanso omwe ali ndi zosowa zachangu za kupewa ndi kuwongolera myopia.
3. Amene sali oyenera kuvala magalasi a Ortho-K kapena safuna kuvala magalasi a Ortho-K.
Zindikirani: Odwala omwe ali ndi strabismus, masomphenya osadziwika bwino a binocular, ndi anisometropia ayenera kuunika ndi dokotala ndikuwona kuti ndi koyenera.
Chifukwa chiyani kusankha?defocusingmagalasi?
1. Magalasi ofooketsa amathandizira kuwongolera myopia.
2. Njira yopangira ma lens opumira ndi yosavuta ndipo palibe kusiyana kwakukulu pakuwunika kuchokera ku magalasi abwinobwino.
3. Magalasi ofooketsa samalumikizana ndi cornea ya diso, kotero palibe vuto la matenda.
4. Poyerekeza ndi ma lens a Ortho-K, magalasi ochotsa chidwi ndi osavuta kusamalira ndi kuvala, ma lens a Ortho-K amafunika kutsukidwa ndi kupha tizilombo toyambitsa matenda nthawi zonse pamene akuchotsedwa ndi kuvala komanso amafunikanso njira zothandizira kuti asamalire.
5. magalasi ofooketsa ndi otsika mtengo kuposa magalasi a Ortho-K.
6. Poyerekeza ndi magalasi a Ortho-K, magalasi osayang'ana akugwira ntchito kwa anthu ambiri.
