Sarudzo dzakasarudzwa dzakagadzirisa zvigadziridza mufananidzo wakajeka uye uri nani pane retina yeziso, zvinobatsira kukurudzira nekuwedzera munda wekuona, kudzorera binocular chiratidzo, kuderedza kuitika kwekuona kuneta uye kuwedzerwa kuona.
Nhasi mushambadzi unopa mhando dzakawanda dzekutumira lenzi, dzakasiyana muhupenyu uye hupenyu hwehupenyu. Saka kusarudzwa kwekanakisisa kune munhu mumwe nomumwe kunogona kuva kwakaoma. Munguva iyi, ophthalmologists vakawana ruzivo rwakakwana nevarwere vakadaro uye vanopa mazano akawanda pamusoro pekuongororwa uye kusarudzwa kwema-lens anobatsira uye kushandisa kwavo kwakakodzera.
Kutanga, soft lenses inobata zvakasimba corneal epithelium, iyo inonyanya kunetseka nekushayikwa kwe okisijeni. Nharaunda yechipfuva (iyo nzvimbo yekuwana mishonga yeropa kune cornea, iyo inonzi dark groove iyo inoparadzanisa cornea kubva pachigera) ndiyo inokonzera masero ematsipa, anovimbisa kuve nekuvandudzwa kwezvigunwe. Kana mabhizinesi ekufambisa anokanganisa ne-cornea kuti atore okisijeni yakakwana, inobatsira kuvhiringidza kushandiswa kwemasabolism uye kutendeka, kuderedza kuwanda kwe epithelium nedzimwe matambudziko. Oxygen nzara ye cornea haibvumiri kuti ikwanise kumira mabhakitiriya uye inowedzera ngozi yehutachiona.
A new polymer material for soft contact lenses - silicone-hydrogel - ine yakakwirira yeakisijeni inokwana ne hydrophilic properties. Lenzi idzi dzakanaka kupfuura dzimwe kuchengetedza hutano hwemaziso.
Muzvinyorwa, nhasi kune mhando dzinotevera dze lenzi:
• kubva kune hydrogel nehupenyu hwakasiyana-siyana (kubva pa50 kusvika ku95%);
• kubva ku polymethylacrylic (PMMA);
• kubva kune copolymers of silicone.
Kwete kungoruramisa chete
Vakawanda vanodavira kuti zvinyoro zvinyorwa zvinoshandiswa zvinogona kutora girazi chete nemamoto (myopia). Zvechokwadi, huwandu hwezviratidzo zvekubatanidza maonero ekururamisa hwakawanda zvikuru:
• anisometropia kupfuura 2 dpt;
• high degree of myopia uye hypermetropia;
• aphakia;
• astigmatism (isina kururama uye yakakwirira);
• keratoconus.
Parizvino, kusanganisa lensisi zvinoshandiswa kwete chete kururamisa maonero, asiwo nezvemishonga - sechidziviriro uye bhanhire yezvirwere zvinoputira, dystrophic, zvinotambudza, munguva inotevera. Lenses rinogona kushandiswawo nokuda kwekunakisa, somuenzaniso, neais imperfections, nekunaka kwese kwekonoa.
Contraindications
Kune maviri chete avo:
• zvirwere zvinoputika zve cornea uye conjunctiva;
• kusawirirana kwemunhu mumwe nomumwe. Zvinosuruvarisa, panguva ino, nhamba yevanhu avo, nokuda kwezvikonzero izvi, havagoni kushandisa lens soft, iri kuwedzera.
