IDEAL Defocus Yashizwemo Ibice byinshi

Ugereranije na myopiya idakosowe kandi mugihe ukoresheje lens imwe isanzwe yo kureba: Kubijyanye na myopiya idakosowe, ishusho yikintu nyamukuru cyumurima wicyerekezo izaba iri hagati muri retina, mugihe ishusho ya ibintu bya periferi bizagwa inyuma ya retina. Gukosora hamwe ninzira zisanzwe zihindura indege yerekana amashusho kuburyo iba hagati mukarere ka foveal, ariko ibintu bya periferique bigereranwa ndetse bikagera inyuma ya retina, bikavamo periferique hyperopic defocus ishobora gutera uburebure bwa axial.

Igenzura ryiza rya optique rishobora kugerwaho hifashishijwe defocus-point nyinshi, ni ukuvuga ko ikigo kigomba kuba gishobora kubona neza, kandi amashusho ya peripheri agomba kugwa imbere ya retina, kugirango ayobore retina gutera imbere cyane bishoboka aho kwaguka inyuma. Dukoresha igipimo gihamye kandi cyiyongera cya defocus kugirango tugire agace ka myopia defocus. Mugihe umutekano uhagaze neza hagati yinzira, ibimenyetso bya myopia defocus bikozwe imbere ya retina, bikurura ijisho ryijisho kugirango bidindiza imikurire, kugirango bigere ku ngaruka zo gukumira myopiya mu rubyiruko.
