Nekuwedzera kwechirwere chemyopia pasi rose mumakore achangopfuura, hapana kushomeka kwevarwere vanoda kurapwa. Kufungidzirwa kwekuwanda kwemyopia uchishandisa 2020 US Census kunoratidza kuti nyika inoda kuongororwa maziso kwemwana wega wega ane myopia 39,025,416 gore rega rega, paine bvunzo mbiri pagore.
Pavanachiremba vemaziso vanosvika 70,000 munyika yese, nyanzvi yega yega yekutarisira maziso (ECP) inofanirwa kubatsira vana 278 mwedzi mitanhatu yega yega kuti isangane nezvinodiwa pari zvino zvekutarisira maziso evana vane myopia muUnited States. 1 Iyoyo ivhareji yemyopia yevana vanopfuura mumwe inoonekwa uye inorapwa pazuva. Basa renyu rakasiyana sei?
SeECP, chinangwa chedu ndechekuderedza mutoro weprogressive myopia uye kubatsira kudzivirira kutadza kuona kwenguva refu muvarwere vese vane myopia. Asi varwere vedu vanofungei nezvekugadziriswa kwavo uye mhedzisiro yavo?
Kana zvasvika pakurapa kwemapfupa (orthokeratology), mhinduro dzevarwere pamusoro pehupenyu hwavo hunoenderana nekuona dzinonzwika zvikuru.
Ongororo yakaitwa naLipson nevamwe vake, vachishandisa National Institute of Eye Diseases with Refractive Error Quality of Life Questionnaire, yakaenzanisa vanhu vakuru vakapfeka malenzi ekuona nemaziso akapfava nevanhu vakuru vakapfeka malenzi e orthokeratology. Vakagumisa kuti kugutsikana kwese uye kuona kwakafanana, zvisinei, vanenge 68% vevatori vechikamu vaida Ortho-k uye vakasarudza kuramba vachiishandisa pakupera kwechidzidzo. 2 Vanhu vakanyora nezveongororo iyi vakataura kuti vaida kuona masikati asina kugadziriswa.
Kunyange zvazvo vanhu vakuru vangada Ortho-k, ko vana vanogona kuona zviri pedyo here? Zhao nevamwe vake vakaongorora vana vasati vapedza mwedzi mitatu vachipfeka orthodontic.
Vana vanoshandisa Ortho-k vakaratidza hupenyu hwepamusoro uye mabhenefiti mumabasa avo ezuva nezuva, vaive nekatsika kekuyedza zvinhu zvitsva, vaive nechivimbo, vaishingaira, uye vaive nekatsika kekutamba mitambo, izvo zvakazoita kuti vapedze nguva yakawanda vachirapwa mumugwagwa.
Zvinogoneka kuti nzira yakakwana yekurapa myopia inogona kubatsira kuramba ichibata varwere uye kubatsira zvakakwana kudzora kutevedzera kwenguva refu nzira yekurapa inodiwa pakurapa myopia.
Ortho-k yafambira mberi zvikuru mukugadzira malenzi nekugadzirwa kwezvinhu kubva pakatanga kubvumidzwa neFDA kwemalenzi ekuonana e ortho-k muna 2002. Nyaya mbiri dzinonyanya kuoneka mukurapa nhasi: Malenzi eOrtho-k ane musiyano wehupamhi hwemalenzi uye kugona kugadzirisa dhayamita yenzvimbo yekuona kumashure.
Kunyange zvazvo magirazi e meridian orthokeratology achiwanzonyorerwa varwere vane myopia ne astigmatism, sarudzo dzekuaisa dzinopfuura zvikuru dzekugadzirisa myopia ne astigmatism.
Semuenzaniso, zvichienderana nekurudziro yemugadziri, zvichienderana nekuyedzwa kwemuviri kune varwere vane corneal torcity ye 0.50 diopters (D), musiyano mumwe chete wehudzamu hwenzvimbo yekudzoserwa kweropa unogona kupihwa zvichienderana nekuyedzwa kwemuviri.
Zvisinei, diki diki re toric lens pa cornea, pamwe chete ne Ortho-k lens inotarisa musiyano we meridional depth, zvichaita kuti kubuda kwemisodzi kuende zvakanaka uye kuti jira rigare pakati chaipo. Saka, vamwe varwere vanogona kubatsirwa nekugadzikana uye kukodzera kwakanaka kunopihwa nekugadzirwa uku.
Muongororo yekiriniki ichangobva kuitwa, malenzi e-orthokeratology ane dhayamita yeBOZD (5 mm rear vision zone diameter) akabatsira varwere vane myopia. Zvakabuda zvakaratidza kuti 5 mm VOZD yakawedzera kugadziriswa kwemyopia ne 0.43 diopters pakushanya kwezuva rimwe chete zvichienzaniswa ne6 mm VOZD dhizaini (control lens), zvichipa kugadziriswa nekukurumidza uye kuvandudzwa kwekuona (Mifananidzo 1 ne2). 4, 5
Jung nevamwe vake vakaonawo kuti kushandiswa kwelenzi yeBOZD Ortho-k ye5 mm kwakaita kuti dhayamita yenzvimbo yekurapa iderere zvakanyanya. Saka, kune maECPs aivavarira kuwana huwandu hushoma hwekurapa kuvarwere vavo, 5 mm BOZD yakaratidza kubatsira.
Kunyange hazvo maECP mazhinji achinyatsoziva ma contact lenses ekuisa varwere, kungave pakuongorora kana pakuongorora, ikozvino kune nzira itsva dzekuwedzera mukana wekuwana uye kurerutsa maitiro ekuisa ma contact lenses mukiriniki.
Yakatangwa muna Gumiguru 2021, Paragon CRT Calculator mobile app (Mufananidzo 3) inobvumira vanachiremba vekukurumidzira kutsanangura maparamita evarwere vane Paragon CRT neCRT Biaxial (CooperVision Professional Eye Care) orthokeratology systems uye kuadhawunirodha nekudzvanya kushoma. Odha. Magwara ekugadzirisa matambudziko nekukurumidza anopa maturusi ekiriniki anobatsira chero nguva, chero kupi.
Muna 2022, kuwanda kwechirwere chemyopia kuchawedzera pasina mubvunzo. Zvisinei, basa remaziso rine nzira dzepamusoro dzekurapa, maturusi nezvimwe zvinhu zvinobatsira pakuita mutsauko muhupenyu hwevana vane myopia.
