Tech.Sharing |Sei varwere vecataract vachifanira kuisa intraocular lenses

Pane chikamu chiri muziso chinonzi lenzi.Iyo inoonekera kaviri-sided convex lens, iyo inotamba basa rekufambisa kwechiedza uye kutarisa muziso.Pasina iyo, hatigoni kuona zvakajeka.Nekukura kwezera, iyi kristaro inoonekera inova zvishoma nezvishoma turbid, zvichikonzera kudzikira kwekufambiswa kwechiedza.Painodonha kusvika pamwero wakati, inokanganisa chiono chedu uye inova cataract.Munguva yekuvhiyiwa kwecataract, iyo turbid lens inotorwa kunze kuburikidza ne ultrasonic simba.Kana chete turbid lens inotorwa kunze, dambudziko rekufambisa kwechiedza rinogadziriswa, uye chiedza chinogona kupinda muziso zvakare.Asi dambudziko rekutarisa richiripo, saka isu tinofanirwa kuisa yakajeka intraocular lens munzvimbo yepakutanga yelens, iyo isingagone kugadzirisa chete dambudziko rekufambiswa kwechiedza, asi zvakare kugadzirisa dambudziko rekutarisa, kuti tigone kuona kunze kwenyika zvakajeka.Naizvozvo, intraocular lens inofanira kuiswa mukuvhiyiwa kwecataract, inova kuvhiyiwa kwakakwana kwecataract
