Ma keʻano laulā, hana ʻia ke ʻoki cataract ma ka hoʻololi ʻana i ka lens maʻi me kahi lens artificial e mālama i ka cataracts. ʻO nā hana cataract maʻamau i hoʻohana ʻia ma ke keʻena keʻena penei:
1. Extracapsular cataract extract
Ua mālama ʻia ka capsule hope a ua wehe ʻia ka nucleus lens maʻi a me ka cortex. Ma muli o ka mālama ʻia ʻana o ka capsule hope, mālama ʻia ke kūpaʻa o ka hale intraocular a hoʻemi ʻia ka pilikia o nā hoʻopiʻi ma muli o ka vitreous prolapse.
2. Phacoemulsification cataract aspiration
Me ke kōkua o ka ikehu kani ultrasonic, ua hoʻopaʻa ʻia ka capsule hope, a ua wehe ʻia ka nucleus a me ka cortex o ka lens maʻi me ka hoʻohana ʻana i ka capsulorhexis forceps a me ka pahi kīwaha nucleus. ʻOi aku ka liʻiliʻi o nā ʻeha i hana ʻia ma kēia ʻano o ka ʻoki ʻana, ʻoi aku ka liʻiliʻi ma mua o 3mm, a ʻaʻole koi ʻia ka suture, e hōʻemi ana i ka hopena o ka maʻi ʻeha a me ka astigmatism corneal. ʻAʻole wale ka pōkole o ka manawa hana, pōkole ka manawa hoʻihoʻi, hiki i nā maʻi ke hoʻihoʻi hou i ka ʻike i ka wā pōkole ma hope o ka hana.
3. Ua kōkua ʻo Femtosecond laser i ka unuhi ʻana i ka cataract
Hoʻopaʻa ʻia ka palekana a me ka pololei o ka mālama laser.
4. Hoʻokomo ʻia nā lens intraocular
Hoʻokomo ʻia kahi lens artificial i hana ʻia me kahi polymer kiʻekiʻe i ka maka e hoʻihoʻi i ka ʻike.
