Kusanganiswa kwe-astigmatism inoratidzika yakaremara kuonekwa, umo maviri hyperopia uye myopia anocherechedzwa panguva imwe chete muziso rimwe, i.e. mhando mbiri dzekuputsa kwekuregererwa dzakabatanidzwa. Panyaya iyi, hapana chinotarisa chimwe chemasikati pane retina, uye mufananidzo uri muziso rinowedzera kaviri: pamberi pe retina uye seri kwe retina. Saka, chiratidzo chinonyangadza zvikuru. Mune vanhu vanotambura nehutachiona huno, iyo cornea yeziso iri zvishoma kana kuti, zvakare, concave. Kusanganiswa kwe-astigmatism kunogona kuva mumeso maviri, uye kune imwe chete yavo.
Zvinokonzerwa neastigmatism yakavhenganiswa
Iyo yakawanda yezviitiko zveastigmatism yakavhenganiswa inobatanidza nehupenyu. Uyewo, hutachiona hunogona kuitika nekuda kwekuvhiyiwa kwemaziso kana mushure mekukuvadzwa kwemaziso, zvichikonzera kuora kwekonoa. Zvimwe zvinokonzera kukanganisa kwakadaro kungangove kuchinja kwakasiyana-siyana mumakorome anokonzerwa nezvirwere (somuenzaniso, keratonus).
Zviratidzo zveastigmatism yakavhenganiswa
Nehupenyu hwechirwere chechirwere ichi, kuratidzwa kwayo kwave kuchiratidzwa muhuduku. Kuonekwa kwakanaka uye astigmatism yakasanganiswa yakaderera, zvose zvakatariswa zvinhu zvakatsauka: vanorasikirwa nekujekesa kwavo, vanoputika, uye maonero avo chaiwo uye kureba kwavo kune zvakaoma. Mukuwedzera, varwere vane astigmatism yakavhengana vanoona kukurumidza kuneta kwemaziso, kunyanya pakushanda, izvo zvinoda nguva dzose kutarisirwa uye kusimba kwemaonero. Kakawanda vanove nemusoro weparoxysmal.
Nzira yekurapa astigmatism yakasanganiswa sei?
Nokuda kwekuongororwa, an ophthalmologic kuongorora achishandisa matafura uye magirasi emagetsi anodiwa kuti aone musiyano mukuputika kwekromnea. Computer diagnostics inoitwawo. Mushure meizvozvo, mazano ehutano anosarudzwa.
Nenzira yakanaka, kunyange istigmatism yakavhenganiswa nhasi inonyanya kunetseka kugadziriswa kwakanaka uye kurapa. Kunyatsokumbira chiremba kuna chiremba ane zviratidzo zvehutano kunobvumira kudzivisa matambudziko ( strabismus , kuderera kwakapinza muono).
Nzira dzokuchengetedza dzinoshandiswa pakurapa kweastigmatism yakavhenganiswa inosanganisira pakusarudzwa kwemaonero ekururamisa maonero: maitiro egadzirisheni kana kuti lens contact, iyo inobvumira kugadzirisa musiyano mune simba rekuona kwemeri miviri miviri yeziso. Mumagirazi ane astigmatism yakavhenganiswa, kusanganiswa kwegirasi yegicyl uye yakaoma inoshandiswa. Shandisa lenzi, izvo zvinogona kuva zvakaoma kana zvinyorova, zvine mavara. Mazuva ano lenzi dzakanaka dzinokubvumira kuti uzvishongedze kwenguva yakareba usingatombogoni kushungurudzika.
Zvisinei, lenzi kana magirasi haakubvumi kuti ubvise zvachose dambudziko racho, asi rinokubvumira kuti uwedzere maziso ako paunoapfekedza. Kugadzirisa mamiriro ezvinhu zvinongogoneka kuburikidza nekushandiswa kwekuvhiya. Iyo inogona kurongerwa mumamiriro ezvinhu apo murwere asingakwanisi retinal pathologies, hapana zvikanda pamusoro peziso reziso kana zvimwe zvirwere zvehupombwe.
Parizvino, kune maviri makuru ekurapa maitiro eokuti astigmatism yakavhenganiswa:
- Kushandisa keratotomy - iyo nzira inosanganisira zvinyorwa zvinyoronyoro pamakona eziso kune dzimwe nzvimbo. Izvi zvinoita kuti zvive nyore kugadzirisa kuputika kwekonoa mune ndege yaidiwa (pamwe chete ne-axis yemafungiro). Asi kushanda kwakadaro kune vazhinji
kushaya simba, iyo huru-iyo yakareba uye inorwadza mushure mekushanda, nguva yakadzika. - Laser mishonga (laser keratomileus) inzira yemazuva ano uye inobudirira. Inosanganisira kukonzera kwemalasiresi pane dzimwe nzvimbo dzemaviri mukati mechando chekorne mushure mekuchekwa kunokosha kwakamboitwa nechinzvimbo chakanaka. Nokudaro, iyo cornea inopiwa maitiro anogara akajeka nemamwe mapiramita, izvo zvinoita kuti munhu awedzere simba rekuona reziso mune imwe meridian uye kuideredza mune imwe.
