Kua ngoikore tō kornea? Akohia te hononga-whiti o te kornea (CXL)!

Kua kōrerotia atu rānei e tō tākuta he mate tōu e kiia nei ko Keratoconus, e angiangi ai te kornea? Kua kōrerotia atu rānei e ia ki a koe tētahi maimoatanga e kiia nei ko te Corneal Cross-Linking, ko te CXL rānei? Tērā pea ka mataku koe ina rongo koe i te ingoa. Engari kāore he take e mataku ai. He maimoatanga tino nui, he whai hua hoki tēnei hei tiaki i tō tirohanga. Me kōrero māmā noa iho tātou i tēnei rā.

He aha rawa te hononga-whiti o te kiriuhi (CXL)?

He whakarāpopototanga noa iho, ko te Corneal Cross-Linking (CXL) he maimoatanga iti e whakapakari ana, e whakakīkī ana hoki i te cornea, te paparanga angiangi, mārama hoki kei mua o tō kanohi .

Whakaarohia tō kanohi he kāmera. Ko te mahi a te kornea o tō tātou kanohi he rite ki te karāhe o taua kāmera. Mā roto i tēnei ka uru te mārama ki te kanohi. Nō reira, he mea nui te āhua tika o tēnei kornea kia mārama ai te tirohanga.

I roto i ngā āhuatanga pēnei i a Keratoconus, ka angiangi haere te kornea, ka ngoikore, ka pupuhi whakamua ki te āhua kōne. He rite ki te pōro porowhita e pupuhi ana i te wāhi kotahi ina pāngia. Ka kiia tēnei ko te kornea ectasia. He mea tēnei e piki haere ana i roto i te wā. I te hurihanga o tēnei āhua, ka tīmata te pōuriuri o tō tirohanga, ā, ka āhua totoro (astigmatism).

Ka mutu te angiangi me te pupū o te kiri mā te maimoatanga CXL. Ka taea e tēnei te aukati i te ngoikore haere o tō kornea, ā, ka ārai hoki i te kino tuturu o te tirohanga.

Me pēhea te mahi a tēnei?

He mea hanga tō tātou kornea i ngā muka pūmua e kiia nei ko te koratene. He rite ēnei ki ngā taura ririki e honoa ana tetahi ki tetahi, e horapa ana pērā i te mata kupenga, e hoatu ana ki te kornea tōna kaha. Ko tēnei tukanga o te herenga o ēnei muka ka kiia ko te "whakawhiti-hononga".

I te wā o te CXL, ka whakamahia e tō tākuta he hihi mārama UV motuhake me ngā pata kanohi kei roto ko te huaora B2 e kiia nei ko te riboflavin. Ina honoa ēnei mea e rua, ka hangaia he hononga hou, kaha ake i waenganui i ngā muka collagen i roto i te cornea. He rite ki ngā miro o te mata kua ngoikore kua mirohia ngātahi, ā, kua whakakahangia. Mā tēnei ka mutu te angiangi me te pupū ake o te cornea.

Mā wai tēnei maimoatanga e tika ana? Ā, mā wai hoki e kore e tika?

Ki te whakatauhia e tō tākuta kei te ngaro te tirohanga tuturu nā te angiangi o tō kornea, ka tūtohu pea ia i tēnei maimoatanga. Me titiro tātou ki te ripanga i raro nei kia kite ai i te wā e tika ana tēnei, ā, i te wā kāore e tika ana.

He pokanga tēnei? He aha te Epi-off?

Ae, he pokanga kanohi iti noa iho te CXL nā te mea ka mahia e te tākuta kanohi. Kaua e manukanuka, ehara i te tapahi nui.

Ko te wāhanga pokanga anake o tēnei ko te tango i te paparanga angiangi i runga i te cornea, e kiia nei ko te epithelium. He rite ki te paparanga angiangi i runga i tō tātou kiri. Ka tangohia kia taea ai te mimiti i te rongoā riboflavin e whakamahia ana e tātou ki roto i ngā paparanga hohonu o te cornea. Ko te ingoa o tēnei tikanga ko te "Epi-off" (ephelium-off). Ko tēnei tikanga te mea tino whakaaetia, ā, he tino angitu hoki i te ao i tēnei wā.

Me whakarite ahau i mua i te maimoatanga?

Ehara tēnei i te tikanga o waho. Ko te tikanga ka taea e koe te hoki ki te kāinga i taua rā anō i muri i te maimoatanga. Kāore he whakaritenga motuhake e hiahiatia ana. Heoi, nā te mea kāore e taea e koe te taraiwa i muri i te maimoatanga, he mea nui kia whai tangata koe hei kawe i a koe ki te kāinga.

He aha ngā mea ka tupu i te wā e rongoatia ana?

E ono tekau meneti te roa o te maimoatanga katoa.I tēnei wā, kei te takoto koe i runga i te moenga. Ka mahi te tākuta i ēnei mahi i runga i te raupapa:

1. Whakangoikore kanohi: Tuatahi, ka pania he rongoā whakangoikore kanohi ki te kanohi kia kore ai e mamae.

2. Te tango i te epithelium: Muri iho, ka tangohia marietia te paparanga o runga o te cornea, te epithelium.

3. Te paninga o te rongoā: Muri iho, tāpirihia he pata kanohi kōwhai e kīia nei ko te riboflavin (huaora B2) ki roto i te kanohi, ka waiho mō te 30 meneti kia pai te mimiti.

4. Mārama UV: Kātahi ka tukuna he hihi mārama UV motuhake ki tō kornea mō te 30 meneti pea. Koinei te wā ka puta te mahi makutu, ka whakapakari i ngā hononga collagen.

5. Te taahiraa whakamutunga: Hei whakamutunga, ka whakamahia ngā paturopi hei ārai i te mate, ka whakamahia ngā pata kanohi steroid hei whakaiti i te pupuhi, ā, ka whakamahia he takai arotahi rangitahi hei tiaki i te kanohi.

Koinā katoa. Kātahi ka taea e koe te hoki ki te kāinga.

He aha ngā painga me ngā mōrearea o tēnei?

Ko te painga nui o tēnei maimoatanga koia anake te maimoatanga e wātea ana i tēnei wā ka taea te aukati i te angiangi me te pupū o te kornea. Mā tēnei ka aukati i te kino haere o tō tirohanga. Ka taea hoki e ia te ārai i a koe kei mate koe i te pokanga nui, pērā i te whakawhitinga kornea, ā muri ake nei.

Heoi anō, pērā i ngā maimoatanga hauora katoa, he iti noa iho ngā tūponotanga. Engari he mea nui kia mahara he tino onge ēnei.

• Te mate urutā.
• Te whara.
• Te tirohanga pōuri tuturu (te kohu o te kornea).

Ka kōrero tō tākuta ki a koe mō ēnei mea.

He pēhea te roa o te wā whakaora i muri i te maimoatanga?

Ko te wā whakaora i muri i te maimoatanga e hiahia ana ki te manawanui.

Tuatahi, me mau koe i tētahi takai karaihe whakapā mō te wiki pea . Koinei te wā e tupu ai anō te paparanga epithelium i tangohia e tātou. I tēnei wā, me whakamahi anō hoki koe i ngā pata kanohi steroid ka tohua e tō tākuta.

Mamae: Whai muri i te maimoatanga, tera pea ka pāngia koe e te mamae, te wera rānei i ō kanohi. Tērā pea ka tino pāngia ētahi e te mamae. Ka hoatu e tō tākuta he pata kanohi hei whakamamae i te mamae. Ki te kore te mamae e memeha ahakoa te whakamahinga o ēnei rongoā, kaua e wehi ki te kōrero ki tō tākuta.

Tirohanga: Ko te mea nui , i ngā rā tōmua i muri i te maimoatanga, ka pōuri haere tō tirohanga i tō mua.Ko te kohu o te kornea tēnei e kiia nei he kohu. He mea noa tēnei, kaua e manukanuka. Ka tīmata te mārama haere o tō tirohanga.

Kei te ripanga i raro nei ngā mea ka pā ki a koe i te wā e ora ana koe.

E rua, e toru rānei ngā marama e toe ana kia tino mārama ai tō tirohanga. Whai muri i tēnā, me whakamahi koe i tētahi huinga mōhiti hou, i ētahi karaihe whakapā rānei.

Āhea koe me kōrero ki te tākuta?

Ki te pā mai he panoni ohorere ki tō tirohanga i a koe e ora ana (hei tauira, te pōuri ohorere, te kite i ngā ira pango) , ki te kore rānei e taea te whakahaere i te mamae e te rongoā kua tohua e tō tākuta, me whakamōhio tonu atu ki tō tākuta.
