He aha ka ʻokoʻa ma waena o nā lens maʻamau a me nā lens defocusing?

E hoʻomaka nā haumāna kula haʻahaʻa a me ke kula kiʻekiʻe i kā lākou hoʻomaha kauwela i hoʻokahi pule.E lilo hou ana nā pilikia ʻike maka o nā keiki i ka nānā ʻana o nā mākua.

I nā makahiki i hala iho nei, i waena o nā ʻano he nui o ka pale ʻana a me ka mālama ʻana i ka myopia, nā lens defocusing, hiki ke hoʻolohi i ka ulu ʻana o ka myopia, ua lilo i mea kaulana i waena o nā mākua.

No laila, pehea e koho ai i nā lens defocusing?Ua kūpono lākou?He aha nā mea e nānā ai i ka optometry?Ma hope o ka heluhelu ʻana i kēia ʻike, manaʻo wau e ʻoi aku ka maikaʻi o nā mākua.

He aha nā lens defocusing?

Ma keʻano laulā, ʻo nā lens defocusing nā lens spectacle microstructured, i hoʻolālā ʻia e loaʻa i kahi kikowaena optical area a me kahi microstructured area, i ʻoi aku ka paʻakikī ma ke ʻano o nā hiʻohiʻona optical a ʻoi aku ka koi ma ke ʻano o ke kūpono ma mua o nā aniani maʻamau.

ʻO ke kikoʻī, hoʻohana ʻia ka ʻāpana waena e hoʻoponopono i ka myopia e hōʻoia i ka "ʻike maka", aʻo ka ʻāpana peripheral i hoʻolālā ʻia e hana i ka myopic defocus ma o kahi hoʻolālā optical kūikawā.Hiki i nā hōʻailona defocus myopic i hana ʻia ma kēia mau wahi ke keʻakeʻa i ka ulu ʻana o ka axis maka, no laila e hoʻolohi i ka piʻi ʻana o ka myopia.

He aha ka ʻokoʻa ma waena o nā lens maʻamau a me nā lens defocusing?

Hoʻopili nā lens monofocal maʻamau i ke kiʻi ʻike kikowaena ma luna o ka retina a hiki ke hoʻoponopono wale i ka ʻike, e ʻae i ke kanaka e ʻike maopopo i ke komo ʻana;

ʻAʻole hoʻokuʻu wale nā ​​lens defocusing i ke kiʻi ʻike kikowaena i ka retina e ʻae iā mākou e ʻike maopopo akā e kālele pū i ka ʻaoʻao ma luna a i mua paha o ka retina, e hana ana i kahi defocus myopic peripheral e hoʻolohi i ka ulu ʻana o ka myopia.

ʻO wai ka mea hiki ke hoʻohana i nā lens defocusing?

1. Myopia ʻaʻole ma mua o 1000 degere, astigmatism ʻaʻole ma mua o 400 degere.

2. ʻO nā kamaliʻi a me nā ʻōpio ke hoʻohonu loa nei ka ʻike a loaʻa iā lākou nā pono koʻikoʻi no ka pale ʻana a me ka mālama ʻana i ka myopia.

3. ʻO ka poʻe i kūpono ʻole no ka hoʻohana ʻana i nā lens Ortho-K a i ʻole makemake e komo i nā lens Ortho-K.

'Ōlelo Aʻo: Pono e loiloi ʻia e ke kauka nā maʻi me ka strabismus, ka ʻike binocular abnormal, a me ka anisometropia a noʻonoʻo i ke kūpono inā kūpono.

No ke aha e koho aidefocusinglens?

1. He mea maika'i nā lens defocusing i ka ho'omalu 'ana i ka myopia.

2. He ma'alahi ke ka'ina hana o ka ho'oku'u 'ana i nā lens defocusing a 'a'ohe 'oko'a nui o ke ka'ina ho'okolokolo mai ka lens ma'amau.

3. ʻAʻole pili nā lens defocusing me ka ʻili o ka maka, no laila ʻaʻohe pilikia maʻi.

4. Ke hoʻohālikelike ʻia me nā lens Ortho-K, ʻoi aku ka maʻalahi o ka mālama ʻana a me ka ʻaʻahu ʻana i nā lens defocusing, pono e holoi ʻia nā lens Ortho-K i kēlā me kēia manawa e lawe ʻia a hoʻokomo ʻia a pono pū kekahi i nā hoʻonā mālama kūikawā e mālama iā lākou.

5. ʻoi aku ka maikaʻi o nā lens defocusing ma mua o nā lens Ortho-K.

6. Hoʻohālikelike ʻia me nā lens Ortho-K, pili nā lens defocusing i kahi ākea o ka poʻe.
