Vaya vanopfeka mavarai kwenguva yakareba vanoziva kuti vakaneta sei maziso avo manheru. Izvi zvinotanga, kutanga kwezvose, nekuda kwekusava nekusviba kwe okisijeni kune cornea. Silicone-hydrogel lens rinogadzirisa dambudziko iri zvachose - kusiyana nemagetsi echell hydrogel lenses, anobvumira maziso kunyatsopindira mukushandurwa kweokisijeni.
Mhando dzakanakisisa dzinobudisa silicone-hydrogel lenses
Mvura inogadziriswa ye hydrogel uye silicone-hydrogel contact lens inenge yakafanana, asi dk Dk / t inonzi chiyero che okisijeni chichikwanisa kuvharidzirwa kwemarara mukati-iyo yekupedzisira inogona kunge yakawanda kakawanda. Semuenzaniso: PureVision lenzi kubva kuBausch & Lomb kubva ku silicone hydrogel ine Dk 110, uye hydrogel lens yemabhizimisi mamwechete emuAmerica, asi kubva munhepfenyuro yeSofLens 59 inogona kuzvirumbidza chiyero che oxygen conductivity ye16.5 chete. Zvose izvo uye dzimwe lenzi zvakagadzirirwa kushandiswa kwegore negore.
I-high-quality lenses kubva ku-silicone hydrogel inowanikwa kubva kuvakakura makuru:
- Ciba Vision;
- Alcon;
- Bausch & Lomb;
- Cooper Vision;
- Zeiss.
Vane mutsara wezuva rimwe-silicone-hydrogel lens uye lenzi kwenguva refu. Nemhaka yepamusoro Dk maitiro, yakave yakakwanisa kuramba ichipfekedzana ma-lens kwemwedzi inoverengeka. Iye zvino haugoni kubvisa lens usiku kunze kwekukuvadza maziso. Mhinduro ye silicone-hydrogel lenses haisi yakasiyana nemazuva ose.
Ratidza silicone-hydrogel lens
Pamusana pekuti iyo yakagadziriswa yemajekiti inogadzirwa, inokwanisa kukwanisa oksijeni yakaderedzwa zvikuru. Kunyangwe kuwedzera silicone kune hydrogel, dambudziko harigoni kugadziriswa zvachose - marara lenzi haagoni kupfeka kwenguva yakareba kupfuura maawa gumi nemaviri mushure. Kunyange zvakadaro, ivo vanofadza zvikuru pamberi pedu. Inonyanya kuonekwa nemarara lenzi kubva kuSilicone hydrogel - Air Optix Muto kubva kuAmerica kambani Alcon.
