Me ka hoʻomohala ʻana o keratoconus i ka pae mua, hiki ke hoʻoponopono i nā pilikia ʻike me nā lens contact maʻamau. Akā i ka lā ma hope, pono ke koho ʻana i nā lens keratoconus kikoʻī.
Hoʻokumu ʻia ke Keratoconus ma muli o kahi kaʻina dystrophic i loko o ka cornea, e alakaʻi ana i kona thinning, ka hoʻokumu ʻana o kahi protrusion cone. ʻOiai ua wehewehe ʻia ka pathology ponoʻī no ka manawa lōʻihi, ʻaʻole i hoʻokumu ʻia ke kumu kūpono o kona hoʻomohala ʻana a hiki i kēia lā, a ma hope o ka hana ʻana i ka maʻi, paʻakikī ke hoʻoholo i ke ʻano o ka papa.
Hōʻike nā hōʻike i ka wā ʻōpio, maʻamau ma 15-25 mau makahiki, hiki ke hoʻomohala ʻia me ka wikiwiki a me ka lohi, i kekahi manawa nalo koke ka maʻi, akā i kekahi mau manawa, hiki ke holomua me ka deformation o ka cornea.
Ma waena o nā hoʻopiʻi koʻikoʻi, hiki ke ʻike ʻelua, nā hōʻailona o ka myopia, i lilo i kumu no ke koho ʻana i nā aniani a i ʻole nā lens, akā kōkua lākou no ka manawa pōkole a hōʻike i ke kumu maoli o ka pathology i ka topography o ka cornea.
ʻO ke kumu, me ka keratoconus, myopia a i ʻole astigmatism e pili ana i ka hoʻololi ʻana i ka curvature o ka cornea, akā ʻo nā lens maʻamau a i ʻole nā aniani e lilo i "liʻiliʻi" ma lalo o hoʻokahi makahiki ma muli o ka piʻi ʻana o nā maʻi optical.
Hiki iaʻu ke hoʻohana i nā lens me keratoconus?
He mea nui e hoʻoikaika i ka hoʻohana ʻana i nā aniani a i ʻole nā lens i ka hoʻomohala ʻana i ke keratoconus ʻaʻole kōkua i ka mālama ʻana i ka pathology. ʻO nā huahana Optical wale nō ke kōkua i ka uku ʻana i nā hemahema ʻike i kēia manawa, akā hiki i ka maʻi ponoʻī ke hoʻomau i kona holomua.
Hoʻohana pinepine ʻia nā aniani no ka hoʻoponopono ʻana i nā pathologies ʻike e kūʻē i ke kua o keratoconus, ʻaʻole hiki iā lākou ke hoʻopau loa i nā aberrations. Hoʻopili pono nā leka pili i ka ʻili o ka ʻili, a no laila kōkua i ka hoʻopau ʻana i nā pilikia ʻike.
He aha nā lens maikaʻi no keratoconus?
Hiki ke hoʻohana wale ʻia nā lens maʻamau maʻamau i ka pae mua o ka pathology, inā ʻo nā loli refractive a hiki i 2,5 diopters. A laila, hiki ke loaʻa ka ʻike maʻemaʻe me ka hoʻohana ʻana i kahi lens hoʻolālā toric. Eia kekahi, pono e koho i nā hiʻohiʻona me nā mea silico-hydrogel, ma muli o ko lākou kiʻekiʻe gas permeability.
I ka hopena hope o ka maʻi, hoʻohana ʻia nā lens keratoconus kūikawā, hana ʻia lākou e kauoha e like me ka nui o kēlā me kēia o ka cornea. Hiki iā lākou ke palupalu a paʻakikī a hybrid paha.
He aha ka ʻokoʻa ma waena o nā lens keratoconus a me nā lens maʻamau?
ʻO ke koho ʻana i nā lens no ka poʻe maʻi me keratoconus e mālama wale ʻia e ka ophthalmologist. E hana ʻia kēlā me kēia, e like me ka nui o ke koʻo. Inā he mau huahana palupalu kēia i hana ʻia i kēlā me kēia, ua māhele ʻia lākou i ʻelua pūʻulu:
- axisymmetric, loaʻa ka mānoanoa i ke kikowaena - hiki i kēia mau lens ke hoʻoponopono i ka myopia, akā ʻaʻole hiki ke hoʻopau i ka astigmatism, kūpono lākou no keratoconus wale nō, kahi i emi ai ka pōʻino o ka cornea i ke kikowaena ma mua o ka periphery;
- Hiki i nā lens toric ke kōkua me ka astigmatism, ʻoi aku ka nui o kona kiʻekiʻe.
Inā he mau lens paʻakikī kēia, ua māhele ʻia lākou e ka nui a māhele ʻia i ʻelua pūʻulu:
- me kahi anawaena liʻiliʻi (a hiki i ka 10 mm), ʻo ke koʻa - ʻoi aku ka nui o nā lens like ʻole i hana ʻia e kauoha, koho iā lākou no ka hōʻoluʻolu ʻoi loa.
- me ka nui nui (mai ka 13,5 mm a ʻoi aʻe paha), corneoscleral a scleral paha, nā huahana gas-permeable i hoʻomaha ʻia i ka sclera me ka ʻole e hoʻopā i kahi o uXNUMXbuXNUMXbke keratoconus ponoʻī - ʻoi aku ka ʻoluʻolu, akā ʻoi aku ka paʻakikī. e koho.
ʻO nā huahana Hybrid kahi hui o nā hui ʻelua i hala. Hana ʻia ko lākou ʻāpana waena i kahi mea oxygen-permeable, akā ma ka periphery ua palupalu lākou, i hana ʻia me ka silicone hydrogel. He ʻoluʻolu kēia mau lens, hoʻopaʻa maikaʻi ʻia i ka cornea, hāʻawi i ka hoʻoponopono hiʻohiʻona kiʻekiʻe, akā ʻaʻole hiki ke hoʻohana i ka wā maloʻo ka cornea.
Nā loiloi o nā kauka e pili ana i nā lens no keratoconus
"Ma muli o ka astigmatism koʻikoʻi e pili ana i ke keratoconus, ma ke ʻano he lula, lilo ka hoʻoponopono hoʻopili ʻana i koho no ka loaʻa ʻana o ka ʻike ʻike maikaʻi loa," wahi a ia. ophthalmologist Maxim Kolomeytsev. - Hiki ke ʻokoʻa ka manawa a me ka pinepine o ka hoʻololi ʻana i nā lens ma muli o ke ʻano o ka lens i koho ʻia (nā lens contact soft a i ʻole nā lens permeable gas paʻa) a me ka wikiwiki o ka piʻi ʻana o ka maʻi.
Nā nīnau a me nā pane kaulana
Ua kamaʻilio mākou me ophthalmologist Maxim Kolomeytsev e pili ana i ka pilikia o keratoconus a me ka hoʻoponopono lens i loko o ia mea, i wehewehe i kekahi o nā nuances o ka lāʻau.
