He mea hoʻohana maikaʻi ʻo Plexiglass i ka lāʻau lapaʻau, ʻo ia ka hana ʻana i nā corneas artificial.Inā uhi ʻia ka ʻōniʻoniʻo o ka maka o ke kanaka me nā mea opaque, ʻaʻole hiki i ke kukui ke komo i ka maka.He makapō kēia ma muli o ka leukoplakia corneal piha, a ʻaʻole hiki ke mālama ʻia ka maʻi me nā lāʻau lapaʻau.
No laila, manaʻo ka poʻe ʻepekema lapaʻau e hoʻololi i ka cornea me nā kiko keʻokeʻo me ka cornea artificial.ʻO ka mea i kapa ʻia ʻo artificial cornea ʻo ia ka hoʻohana ʻana i kahi mea alohilohi e hana i ke kolamu aniani me ke anawaena he mau millimeters wale nō, a laila e wili i kahi puka liʻiliʻi ma ka ʻili o ka maka o ke kanaka, e hoʻoponopono i ke kolamu aniani ma ka ʻili, a me ke kukui. komo i ka maka ma ke kolamu aniani.Hiki i ka maka kanaka ke ike hou i ka malamalama.
I ka makahiki 1771, ua hoʻohana kekahi ophthalmologist i ke aniani ʻōpika no ka hana ʻana i kolamu aniani a hoʻokomo ʻia ke koʻo, akā ʻaʻole i kūleʻa.Ma hope mai, ʻaʻole i pau ka hoʻohana ʻana i ke aniani ma kahi o ke aniani optical ma hope o ka hapalua makahiki.I ke Kaua Honua ʻElua, i ka wā i hāʻule ai kekahi mau mokulele, ua puhi ʻia ka uhi cockpit i hana ʻia me ka plexiglass ma luna o ka mokulele, a ua hoʻopili ʻia nā maka o ka pilote me nā ʻāpana plexiglass.Ma hope o nā makahiki he nui, ʻoiai ʻaʻole i lawe ʻia kēia mau ʻāpana, ʻaʻole lākou i hoʻoulu i ka mumū a i ʻole nā mea ʻino ʻē aʻe i ka maka o ke kanaka.Ua hōʻike ʻia kēia hanana e pili ana ka plexiglass a me ke kino kanaka.I ka manawa like, ua hoʻoikaika ia i nā ophthalmologists e hana i nā cornea artificial me ka plexiglass.Loaʻa iā ia ka hoʻouna māmā maikaʻi, nā waiwai kemika paʻa, ʻaʻohe mea ʻawaʻawa i ke kino o ke kanaka, maʻalahi e hana i ke ʻano i makemake ʻia, a hiki ke kūpono me nā maka kanaka no ka manawa lōʻihi.Ua hoʻohana mau ʻia nā cornea artificial i hana ʻia me ka plexiglass i loko o ke keʻena.
