Me whakatō karāhe kanohi koe mō te katarata? Kia ako tātou i ngā mea katoa e pā ana ki ēnei karāhe kanohi (Ngā Karāhe Mata - IOL) i roto i tētahi huarahi māmā!

He kuia, he koroua rānei kei te kāinga e amuamu ana he pōuriuri ōna kanohi, ā, he pōuriuri ngā mea katoa? He uaua rānei ki a koe te pānui i te nūpepa, te titiro rānei ki tō waea i a koe e pakeke haere ana? Ko te take matua o tēnei pea ko ngā "cataracts". Nō reira, i tēnei rā ka kōrero tātou mō tētahi mea iti engari he mea tino nui ka whakaurua ki roto i ō tātou kanohi i te wā pokanga. Koia te karāhe kanohi-roto, e kiia nei e tātou i roto i te rongoā, ko ngā Karāhe Mata-roto, ko ngā IOL rānei.

He aha ēnei IOL? He māmā noa iho...

Whakaarohia tō kanohi he kāmera pai. He karāhe tūturu tō tēnei kāmera. Ko te mahi a tēnei karāhe he arotahi i te mārama e puta mai ana i ngā mea e kitea ana e tātou, me te whakarato i tētahi ahua mārama ki te retina i roto i te kanohi. I roto i te wā, ina koa ka pakeke haere tātou, ka tīmata te pōuri o tēnei karāhe tūturu, ka rite ki te miraka. Koinei te mea e kiia nei e tātou he "cataract."

Whakaarohia te mea ka tupu mēnā ka paru, ka puehu, ka rakuraku, ka pōuriuri te karu o te kāmera? Kāore ngā whakaahua e tangohia ana e koe e mārama ana, tika? Koinei te mea ka tupu ina pāngia koe e te katarata. Nō reira, ko tāu mahi ki te pokanga he tango i te karu tūturu kua pōuriuri, ka whakakapia ki tētahi karu mārama, hangai ka taea te waiho tonu ki roto i te kanohi mō ake tonu atu . Ko taua karu hangai te mea e kiia nei e tātou he IOL .

Ehara i te mea ka taea anake e ēnei karāhe arotahi IOL te whakatika i te katarata, engari ka taea hoki e koe te whakatika i ētahi atu raruraru tirohanga maha ka taea e koe te whakatika mā te whakamahi i ngā mōhiti, i ngā karāhe arotahi rānei.

• Te matapōkere: He mārama te titiro ki ngā mea i te taha tata, engari he pōuriuri te titiro ki ngā mea i tawhiti.
• Te Tirohanga Tata (Hyperopia): Ka mārama te titiro mai i tawhiti, engari he uaua ki te pānui i ngā mea e tata ana, inā koa ngā pukapuka.
• Te Matakite o te Pō: He āhuatanga e pāngia ana e te tini tāngata neke atu i te 40 tau te pakeke, e hiahia ana ki ngā mōhiti mō te tirohanga tata.
• Te Astigmatism: He āhuatanga e kore ai te mārama e arotahi ki te wāhi kotahi, ka puta he tirohanga hē, nā te paku rerekētanga o te āhua o te kanohi.

Kia mau ēnei karaihe IOL ki roto i tō kanohi, ka roa te ora. Nō reira, ka taea e koe te whakaiti i tō whakawhirinaki ki ngā mōhiti.

Ko wai e hiahia ana ki ēnei karaihe IOL?

E rua ngā rōpū matua o te tangata e tino whai hua ana i ēnei karāhe arotahi IOL.

1. Mō te hunga he katarata: Mena kua tipu te katarata ki te wāhi e whakararuraru ana i tō tirohanga, me tango ma te pokanga. Whai muri i te tangohanga, me tino whakauruhia he karāhe IOL ki roto i te kanohi. Ki te kore, kāore e taea te whakaora i te tirohanga. Koinei te take e mahia ai te nuinga o ngā whakaurunga IOL ki Sri Lanka.

2. Mō te hunga he ngoikore te tirohanga engari kāore e tika ana mō te pokanga pēnei i te LASIK:He raruraru tirohanga tō ētahi tāngata e hiahia ana ki ngā mōhiti, engari kāore pea e taea e rātou te mahi pokanga kanohi taiaho (LASIK). I roto i ēnei āhuatanga, ka taea te pokanga whakawhiti arotahi, arā, te tango i te arotahi tūturu me te whakatō i tētahi IOL.

He aha ngā momo karaihe IOL? Ko tēhea te mea tika māu?

Koinei te raruraru o te tini tāngata. He maha ngā momo IOL. He painga, he ngoikoretanga hoki o ia momo. Mō ētahi karaihe, me whai mōhiti tonu pea koe mō ngā mea pēnei i te pānui pukapuka, nūpepa rānei. Ka taea e ētahi karaihe "tino pai" te whakaiti i tō whakawhirinaki ki ngā mōhiti, engari ka taea hoki e rātou te whakaputa pānga taha pēnei i te kanapa me ngā porowhita huri noa i ngā rama i te wā e taraiwa ana i te pō.

Nō reira, he mea tino nui kia kōrero koe ki tō tākuta kanohi, kia whiriwhiria ai te karaihe e tino pai ana mō tō āhua noho, ō hiahia, me ō manakohanga.

Hei whakamāmā ake i te mārama, me titiro tātou ki ngā momo matua o ngā karu arotahi i roto i tētahi ripanga.

Ētahi atu momo arotahi motuhake

• Ngā karāhe ka taea te whakarite mārama (LAL): He rerekē paku ēnei. I muri i te pokanga, ka taea e tō tākuta te whakamahi i ētahi maimoatanga mārama ultraviolet (UV) motuhake hei whakarerekē mārire i te kaha o ēnei karāhe kia whiwhi ai koe i te tirohanga e hiahiatia ana e koe. He karāhe monofocal anō hoki ēnei, nō reira me hiahia koe ki ngā karāhe mō te tirohanga tata.
• Ngā Arotahi Phakic: Ko te tikanga ka whakamahia ēnei mō ngā taiohi. Kāore te arotahi tūturu e tangohia. Engari, ka whakatōkia tēnei arotahi ki mua i te arotahi tūturu. Ka whakamahia hei whakatika i te tirohanga tata o te hunga kāore e tika ana mō te maimoatanga taiaho.

Ko te mea nui, kāore he mea e kiia nei ko "te karāhe arotahi pai rawa atu." Ko "te karāhe arotahi e pai ana ki a koe" anake. Kei te hauora o ō kanohi, o ō mahi o ia rā, me ō tumanakohanga te mea e hiahiatia ana.

Whakaarohia i mua i te kōrero ki tō tākuta.

I mua i tō haerenga ki te kite i tō taote kanohi, pātai atu ki a koe anō i ēnei pātai. Kātahi ka mārama koe ki tāu e hiahia ana.

• He pai ki ahau te mau mōhiti i ētahi wā? Mena koinā, mō ngā take aha? (hei tauira, te pānui pukapuka noa? I ngā wā katoa rānei?)
• He aha te momo tirohanga e hiahiatia ana e au mō taku mahi? Kei te titiro au ki te rorohiko i te rā katoa? Nō reira, he pai ki ahau te mau mōhiti mō taua mahi?
• He maha tonu taku taraiwa i te pō?Nō reira, ka taea e au te taunga ki te kite i ngā mowhiti e tiaho ana i te taha o ngā rama?
• He aha aku mahi whakangahau? He tangata mahi uaua ahau, pērā i te tuitui, te tuhi rānei? He tangata tākaro hākinakina rānei ahau, he tangata pai rānei ki te noho ki waho? Ki tehea te nui o te whakararuraru a ngā mōhiti i ēnei mahi?
• He aha taku tahua mō te pokanga? I roto i te hōhipera kāwanatanga, ka tukuna noa ngā karāhe arotahi kotahi-kanohi. Heoi, me utu pea koe i ētahi atu mō ngā karāhe arotahi motuhake pēnei i ngā karāhe arotahi maha-kanohi. I roto i te hōhipera tūmataiti, he rerekē ngā utu i runga i te momo karāhe arotahi. Kia mōhio koe ki tēnā i mua i te wā.

He aha ngā raruraru pea e pā ana ki te whakaurunga IOL?

He tino angitu te whakaurunga IOL i ētahi wā. Heoi, pērā i ngā pokanga katoa, tera pea ētahi raruraru onge ka puta. Kāore he mea hei wehi i ēnei, engari he mea pai kia mōhio ki ēnei.

• Te Whakapōuritanga o te Kapu o Muri: Ka kiia hoki tēnei ko te "katarata tuarua." I muri i ngā marama, i ngā tau rānei i te pokanga, ka puta he paparanga angiangi o te pōuri i muri i tō IOL. He mea tino noa tēnei. Ka taea e tēnei te whakapōuri anō i tō tirohanga. He tino ngāwari te rongoā i tēnei. I te nuinga o te wā, ka taea te tango i te paparanga i roto i ngā meneti torutoru i te whare hauora mā te whakamahi i te hihi laser, hei whakamārama i tō tirohanga.
• Te nekenekehanga o te IOL: Ka neke te karāhe kua whakatōkia ki waho o tōna tūranga. He mea tino onge tēnei. He nui ake te mōrearea mō te hunga whai mate kanohi, mō te hunga rānei kua pāngia e te whiunga kino ki te kanohi.
• Te mate UGH (Uveitis-glaucoma-hyphema syndrome): He mate tino onge tēnei e pā ana ki ngā wāhanga o te kanohi, pērā i te iris, nā te mea ka pā te karāhe IOL ki te karu.
• Te whakapōuri i te IOL: Te pōuri o te karāhe horihori tonu. He tino onge tēnei i roto i ngā karāhe o ēnei rā.
• Te Ohorere Tirotiro: Whai muri i te pokanga, tērā pea kāore tō tirohanga e tino mārama pērā i tā kōrua ko tō tākuta i tumanako ai. I tēnei wā, ka whakamāramahia e tō tākuta ō kōwhiringa, pērā i te whakaae ki te tirohanga e tū ana, te whakamahi rānei i ngā mōhiti, te whiwhi maimoatanga taiaho, te whakakapi rānei i tētahi IOL.

Mena he āwangawanga āu mō tētahi o ēnei mea, kōrero ki tō tākuta i mua i te pokanga. Māna e whakamārama ki a koe ngā mōrearea i runga i tō hītori hauora me te hauora o ō kanohi.
