Abanyeshuri bo mumashuri abanza nayisumbuye bazatangira ibiruhuko byabo mucyumweru.Ibibazo by'icyerekezo cy'abana bizongera kwibandwaho n'ababyeyi.
Mu myaka yashize, muburyo bwinshi bwo kwirinda no kurwanya myopiya, linzira ya defocusing, ishobora kudindiza iterambere rya myopiya, imaze kumenyekana cyane mu babyeyi.
None, nigute ushobora guhitamo lens ya defocusing?Birakwiriye?Ni izihe ngingo ugomba kumenya muri optometrie?Nyuma yo gusoma ibikurikira, ngira ngo ababyeyi bazumva neza.
Indwara ya defocusing ni iki?
Muri rusange, linzira ya defocusing ni microstructures linzira yerekana, yagenewe kubamo igice cya optique yo hagati hamwe na microstructures, bikaba bigoye cyane mubijyanye nibipimo bya optique kandi birasabwa cyane muburyo bukwiye kuruta indorerwamo zisanzwe.
By'umwihariko, agace ko hagati gakoreshwa mugukosora myopiya kugirango harebwe "icyerekezo gisobanutse", mugihe akarere kegeranye kagenewe kubyara myopic defocus binyuze muburyo bwihariye bwa optique.Ibimenyetso bya myopic defocus byakozwe muri utwo turere birashobora kubuza gukura kwijisho ryijisho, bityo bikadindiza iterambere rya myopiya.
Ni irihe tandukaniro riri hagati yinzira zisanzwe na defocusing?
Indwara isanzwe ya monofocal yibanda ku ishusho yo kureba hagati kuri retina kandi irashobora gukosora iyerekwa gusa, bigatuma umuntu abona neza mugihe ayambaye;
Indwara ya defocusing ntabwo yibanda gusa ku ishusho yo kureba hagati kuri retina kugirango itwemerera kubona neza ahubwo inerekeza kuri peripheri kuri cyangwa imbere ya retina, ikora defocus ya myopic defocus idindiza iterambere rya myopiya.
Ninde ushobora gukoresha lens ya defocusing?
1. Myopiya itarenza dogere 1000, astigmatism itarenga dogere 400.
2. Abana ningimbi bafite icyerekezo cyimbitse cyane kandi bakeneye byihutirwa mugukumira no kurwanya myopiya.
3. Abadakwiriye kwambara lens ya Ortho-K cyangwa badashaka kwambara lens ya Ortho-K.
Icyitonderwa: Abarwayi bafite strabismus, iyerekwa ridasanzwe rya binocular, na anisometropiya bakeneye gusuzumwa na muganga kandi bagatekereza ko bikwiye.
Kuki uhitamodefocusinglens?
1. Gukuraho linzira bifite akamaro mukurwanya myopiya.
2. Inzira yo guhuza lens ya defocusing iroroshye kandi nta tandukaniro rikomeye mubikorwa byo gukora ibizamini bya lens bisanzwe.
3. Indwara ya defocusing ntishobora guhura na cornea yijisho, ntakibazo rero cyanduye.
4. Ugereranije ninzira ya Ortho-K, lens ya defocusing yoroshye kubungabunga no kwambara, lens ya Ortho-K igomba gukaraba no kuyanduza igihe cyose bayikuyemo bakayambara kandi bakeneye ibisubizo byihariye byo kubitaho.
5. defocusing lens ihendutse kuruta Ortho-K.
6. Ugereranije na Ortho-K lens, defocusing lens ikoreshwa kubantu benshi.
