DEFOCUS yarimo ibice byinshi bya segments byitwa kuko hari umubare muto muto ugaragara kumaso yambaye ubusa kumutwe hejuru yindege, niyo mpamvu izina. DefocUs yinjije inzira nyinshi za segmer ni ubwoko bwayo gukumira no kugenzura ibirahure, bigizwe nibice bibiri. Imwe ni agace keza keza gakoreshwa mugukosora amakosa arose (Myopia, kurema hamwe na Astigmatism), ikindi nikindi kigo cyagutse kuri peripheri ya lens. Zone nyinshi myopic defocus. Iyo uwambaye arebye ibintu muburyo butandukanye, DEFOCUS yinjije ibihugu byinshi bishobora gutanga icyerekezo gisobanutse nanyosia icyarimwe, kandi gishobora gukumira no kugenzura iterambere ryayopia mugihe dukosora iyerekwa.
Ihame nugukoresha uburyo busanzwe bwo gutanga ibitekerezo - phenomenon yo kugenga emmetropisation, kugirango iterambere ryibihure nijisho nigituba ryijisho ryihishe ryegereye ijisho rya emmetropique.
Kugeza ubu, ingimbi yukuri myopia iri ahanini myopiya, iterwa no gukura kw'ijisho. Bitewe no kurambura ijisho, umwanya wibishusho biteganijwe imbere ya retina. Mugihe cyo gukosora lens isanzwe, gukosora neza bigamije gusa icyerekezo nyamukuru, kandi igishushanyo cya lens ubwacyo cyiyongera buhoro buhoro cyangwa kigenda rwiyongera cyane murwego rwakarere hanze yumucyo wo hagati. Nyuma yo gukosorwa, ikintu kimwe gishobora guterwa na Fovea ya macula nta kibazo, akemeza icyerekezo gisobanutse. Ariko, ikintu cyakiriwe na retina ya periferique ntabwo kiri kuruhande rwa retina, ariko igatukana kuruhande rwa retina, ibi kandi bizanaganisha kubyo dutekereza ubu busuzumye Hyperopia, kuri ubu bizwi nkimwe mu mpamvu nyamukuru zitera kwishinga kwa myopia no kwiyongera nabashakashatsi. Ni ukubera ko HYperopia itandukanya uruhande rwinyuma rwa retina itera imikurire yijisho ryinyuma, biganisha ku mikurire yinyuma, biganisha ku mikurire yinyuma kandi bikarushaho kwiyongera kwa Myopiya.
Micro Lens mukarere ka defocus yateguwe bidasanzwe kugira impamyabumenyi itandukanye muri lens imwe mu gace kakosowe, bigatuma ishusho igwa imbere ya renuna, igatanga ibimenyetso kuri refocus no gutanga ibimenyetso kuri axis imbere, kugera kuri Ingaruka zo gutinza Myopia irirusha.

2.Ibisobanuro bikwiye: Inyandiko nyinshi Myopia defocus ni ubwoko bwihariye bwiminyugu yibanze, kandi ikwirakwiriye biroroshye.
3.Ihumure kigh: Ingingo nyinshi Myopia Defocus Lens idafite agace ka Astigmatism kandi ntusabe ijisho ryabantu. Bitandukanye na lens, hamagara CORNEA, ntibazatera ikibazo.
4.Ibitekerezo byinshi: ugereranije nizindi lens, nkibindi bikoresho bya orthoketology, bisaba ko hasunika intoki mugihe cyose cyakuweho hanyuma ugatunga, kandi kubungabunga ibisubizo bisaba ibisubizo byihariye.
5.Ingaruka zo gutinda zayopia ni hejuru ya 59%, kandi ingaruka zo kugenzura imikurire ya axial ni hejuru ya 60%.
