Defocus Incorporated Multiple Segment Lens yitiriwe izina kuko hariho utuntu duto duto tugaragara ku jisho ryambaye ubusa ku mpande zihariye ku buso bwa lens, zitangwa mu buryo bw'ingingo, bityo izina.Defocus Yashizwemo Ibice byinshi Lens ni ubwoko bwo kwirinda myopia no kugenzura ibirahuri, bigizwe nibice bibiri.Kimwe ni agace ka optique gakoreshwa mugukosora amakosa yangiritse (myopiya, kurebera kure na astigmatism), naho ubundi nikigo kigera kuri peripheri ya lens.Uturere twinshi myopic defocus zone.Iyo uwambaye areba ibintu ahantu hatandukanye, defocus yashizwemo ibice byinshi lens irashobora gutanga icyerekezo gisobanutse hamwe na myopia defocus icyarimwe, kandi irashobora gukumira no kugenzura imikurire ya myopiya mugihe ikosora iyerekwa.
Ihame nugukoresha uburyo busanzwe bwo gutanga ibitekerezo bwijisho - phenomenon ya emmetropisation, kugirango ijisho, iterambere ryibonekeje hamwe nishusho yijisho ryijisho ryegerejwe ningaruka ziboneka zijisho rya emmetropique.
Kugeza ubu, myopiya yukuri yingimbi ni myopiya ya axial, iterwa no gukura kwijisho ryijisho.Bitewe no kurambura ijisho, umwanya wibishusho uteganijwe imbere ya retina.Iyo ukosora lens myopia isanzwe, gukosora neza bigamije gusa icyerekezo cyo hagati, kandi igishushanyo mbonera ubwacyo cyiyongera buhoro buhoro cyangwa cyongera kuburyo budasanzwe urwego rwahantu hanze yumucyo wo hagati.Nyuma yo gukosorwa, ikintu kimwe gishobora kwerekanwa kuri fovea ya macula ntakibazo, byemeza neza.Nyamara, ikintu cyakiriwe na retina ya peripheri ntabwo kiri kuri retina, ahubwo cyashushanijwe kuruhande rwinyuma rwa retina, Ibi bizanaganisha kubyo ubu twita hyperopia defocusing, kuri ubu bikaba bizwi nkimwe mubitera nyamukuru gushinga myopiya no kwimbitse kubashakashatsi.Ni ukubera ko hyperopia defocusing kuruhande rwinyuma rwa retina itera gukura kwijisho ryijisho ryerekeza kuruhande rwinyuma, biganisha kumikurire ya axe no kurushaho kwiyongera kwa myopiya.
Lens ya micro mu gace ka defocus yateguwe byumwihariko kugirango igire urwego rutandukanye ninzira imwe mugace gakosorwa, bigatuma ishusho igwa imbere ya retina, bikaviramo myopia defocus kandi igatanga ikimenyetso kumaso yijisho imbere, kubigeraho ingaruka zo gutinza myopiya.
Ibyiza:
1.Ingaruka zo kurwanya myopiya ziragaragara: ingaruka zo gutinda gukura kwa myopiya ni hejuru ya 59%, naho ingaruka zo kugenzura imikurire ya axial ni 60%.
2.Ibikoresho byoroshye: Lens nyinshi ya myopia defocus lens ni ubwoko bwihariye bwa lens imwe yibanze, kandi guhuza biroroshye.
3.Ihumure ryinshi: lens nyinshi ya myopia defocus lens ntagace ka astigmatism kandi ntigahura nijisho ryumuntu.Bitandukanye ninzira yo guhuza, ihuza cornea, ntabwo bizatera ikibazo.
4.Ubuvuzi bworoshye: Ugereranije nizindi lens, nka lens ya orthokeratology, isaba gukaraba intoki no kuyanduza igihe cyose bayikuyemo bakayambara, kandi kubungabunga lens bisaba ibisubizo byihariye byitaweho.
5.Ingaruka zo gutinda kwa myopiya ziri hejuru ya 59%, naho ingaruka zo kugenzura imikurire ya axial ni hejuru ya 60%.
