Tiyeni tiphunzire pang'ono za mayeso a Keratometry, omwe amayesa kupindika kwa maso.

Mukayesedwa maso, mwina mwawonapo dokotala akuyang'ana maso anu ndikugwiritsa ntchito zida zosiyanasiyana kuti awayang'ane. Nthawi zina timadzifunsa kuti, "Kodi ichi chikuyang'ananso chiyani?" Chimodzi mwa mayeso ofunikira kwambiri a maso chimatchedwa Keratometry. Lero, tikambirana za chomwe chili, chifukwa chake chimachitidwa, komanso momwe chimachitikira.

Kodi Keratometry ndi chiyani?

Mwachidule, keratometry ndi mayeso omwe amayesa kupindika kwachilengedwe kwa cornea , gawo lowonekera, lozungulira la kutsogolo kwa diso lanu. Kornea ili ngati chophimba chowonekera pamwamba pa maso athu. Kupindika kwake koyenera ndikofunikira kwambiri kuti maso athu aziona bwino.

Kodi mayeso a keratometry awa amazindikira chiyani?

Kuyezetsa kumeneku kumakuthandizani kudziwa ngati muli ndi vuto lotchedwa astigmatism. Astigmatism ndi vuto lofala kwambiri la refractive lomwe limayambitsa kusawona bwino.

Tangoganizirani, diso labwino nthawi zambiri limakhala lozungulira ngati mpira wa baseball. Kenako, kuwala kukalowa m'diso, kumalunjika pamalo amodzi ndipo timaona bwino. Koma diso la munthu amene ali ndi vuto la astigmatism, kutanthauza kuti cornea, limakhala ngati mpira wa rugby, kapena lotalika pang'ono ngati kumbuyo kwa supuni, kapena limapindika kwambiri kumbali imodzi. Kenako , kuwala kukalowa m'diso, sikulunjika pamalo amodzi, ndipo masomphenya amakhala osawoneka bwino. Mayeso a keratometry awa amayesa kupindika kwa cornea.

Kodi mayeso a keratometry awa amachitika bwanji? Ndi osavuta kwambiri!

Iyi ndi mayeso achangu komanso osapweteka. Katswiri wanu wa maso akhoza kuchita izi mu ofesi yake. Simukuyenera kupatula tsiku kapena nthawi yapadera. Izi zitha kuchitika panthawi yoyezetsa maso nthawi zonse, kapena zitha kuchitika padera ngati dokotala wanu akukayikira kuti muli ndi vuto la astigmatism.

Komanso, ngati muvala ma contact lens m'malo mwa magalasi, kapena ngati mukukonzekera opaleshoni ya cataract, mudzayesedwa ndi keratometry iyi.

Tsopano tiyeni tiwone momwe izi zimachitikira. Dokotalayo amagwiritsa ntchito chipangizo chotchedwa keratometer . Chimawoneka ngati telesikopu. Komabe, sichimayang'ana nyenyezi zakutali, koma maso anu kuchokera pafupi kwambiri. Nazi njira zoyesera:

1. Mudzapemphedwa kuti mukhale pansi, ndipo choyezera chili ndi chothandizira pachibwano chanu komanso malo oti muyikepo mphumi yanu . Mukayika mutu wanu pamenepo, dokotala adzasintha chipangizocho kuti chigwirizane bwino ndi diso lanu.

2. Kenako umauzidwa kuti uyang'ane mkati mwa chipangizocho. Zili ngati kuyang'ana kudzera m'magalasi owonera kutali. Nthawi zina umauzidwa kuti utseke diso lina lomwe silikufufuzidwa.

3. Dokotala amakuuzani zomwe zili mkati mwa chipangizocho.Afunseni kuti ayang'ane chithunzi. Nthawi zambiri chimakhala ndi mabwalo atatu, kapena china chake chonga chandamale chokhala ndi chizindikiro chowonjezera ndi chizindikiro chochotsera.

4. Kenako, dokotalayo pang'onopang'ono amayendetsa chipangizocho , akusuntha zomwe zili mkati, ndikubweretsa zizindikiro zabwino pamalo pomwe zimagwirizana.

5. Dokotala akangofika pa nambala, amalemba muyeso. Kenako, amakonza diso lina la chipangizocho ndikuyesa diso limenelo mwanjira yomweyo.

Taganizirani izi ngati kusintha momwe kamera ikuyang'anira. Dokotala akuyang'ana kuti atsimikizire kuti zithunzizo zikugwirizana ndi kupindika kwa cornea yanu.

Mukuona? N'zosavuta kwambiri, sichoncho? Mutha kumaliza mayeso awa mumphindi zochepa chabe.

Kodi pali kuipa kapena zoopsa zilizonse pa izi?

Ayi, palibe chiopsezo. Kuwala kochokera ku keratometer kungakhale kowala pang'ono mukayang'ana, koma sikungawononge maso anu kapena maso anu.

Koma pali chinthu chimodzi chaching'ono. Ndiko kuti, mayeso a keratometry awa amapereka kuyerekezera koyerekeza kwa cornea yanu, osati muyeso weniweni. Chifukwa cha izi ndikuti mayesowa amayesa cornea yanu, poganiza kuti ndi yozungulira bwino, yozungulira mofanana kulikonse. Koma kwenikweni, maso a aliyense ali ndi kusiyana pang'ono kwachilengedwe. Chifukwa chake, cornea siili ngati mpira.

Koma sizikutanthauza kuti mayesowa ndi opanda ntchito. Tangoganizirani dziko lapansi lokhala ndi mapu a dziko lapansi. Tikudziwa kuti pamwamba pa Dziko lapansi pali mapiri, nyanja, ndi malo osiyanasiyana, kotero si losalala, komanso lozungulira kwenikweni. Koma dziko lapansi ndi chida chabwino chotithandiza kumvetsetsa komwe tili. Keratometry ndi yofanana. Ngakhale kuti si muyeso weniweni wa cornea, ndi yothandiza kwambiri pozindikira mwachangu komanso molondola astigmatism ya anthu ambiri.

Akatswiri ena a maso tsopano akugwiritsa ntchito njira yowunikira maso (yomwe imadziwikanso kuti corneal topography ndi corneal tomography) m'malo mwa keratometry. Izi ndi zapamwamba kwambiri ndipo zimapereka miyeso yolondola kwambiri. Tsopano zikutchuka ngati njira yodziwira astigmatism. Dokotala wanu angachitenso mayeso owunikira maso kuti atsimikizire zotsatira za mayeso a keratometry.

Kodi kuwerenga kwa K kumeneku ndi kotani? Kodi pali phindu labwinobwino?

Zotsatira za mayeso a keratometry zimatchedwa kuwerenga kwa K. Akatswiri a maso amayesa izi m'mayunitsi otchedwa diopters .

Kawirikawiri, cornea yathanzi imasiya kuwala pamlingo wa pafupifupi diopta 43. Ngati cornea ili ndi curve yolimba (corneas yotsetsereka), mtengo uwu umawonjezeka. Ngati curve ndi yochepa (corneas yosalala), mtengo uwu umachepa.

• Ngati cornea yanu ndi yozungulira bwino, imakhala ndi K yofanana pamwamba pake ponseponse.
• Koma ngati muli ndi astigmatism, cornea yanu idzawonetsa ma K awiri . Chimodzi ndi mtengo womwe uli pagawo lopindika kwambiri, ndipo china ndi mtengo womwe uli pagawo lopindika pang'ono, lathyathyathya la cornea. Mayeso a keratometry akuwonetsa kusiyana kumeneku ndi komwe kupindika kuli kwakukulu komanso kotsika kwambiri.

Kuwerenga kwa K kumeneku n'kofunika kwambiri kuti dokotala alembe kupindika kwa cornea yanu. Kuyeza kumeneku kumathandiza dokotala kudziwa chomwe chikuchititsa kusintha kwa masomphenya anu. Komanso, ngati mukufuna opaleshoni ya cataract, kuwerenga kwa K kumeneku kumagwiritsidwanso ntchito posankha lenzi yamkati mwa maso.

Zotsatira ndi manambala awa zingakhale zovuta kuti mumvetse. Koma musadandaule. Dokotala wa maso kapena dokotala wanu angakuthandizeni kumvetsetsa mankhwala anu a maso. Angakuthandizeninso kusankha magalasi abwino kwambiri, magalasi olumikizirana, kapena njira ina yowongolera maso anu.

Kodi tiyenera kupita kwa dokotala wa maso liti?

Katswiri wanu wa maso adzakuuzani kuchuluka kwa nthawi yomwe muyenera kuyezedwa maso nthawi zonse.

Pamene tikukalamba, maso athu amasintha mawonekedwe mwachibadwa, kotero kuti astigmatism imatha kusintha. Komabe, kusintha kwakukulu, mwadzidzidzi kwa astigmatism kungakhale chizindikiro cha vuto lina lomwe liyenera kuchiritsidwa mwachangu, monga keratoconus. Chifukwa chake, ngati muwona kusintha kulikonse m'maso mwanu kapena m'maso mwanu - makamaka ngati maso anu akuwoneka kuti sakuwoneka bwino kapena osawoneka bwino - onetsetsani kuti mwawonana ndi katswiri wa maso nthawi yomweyo.

Pomaliza, zinthu zoti muzikumbukira

Keratometry ndi mayeso ofala kwambiri omwe amagwiritsidwa ntchito ndi akatswiri a maso kuti adziwe matenda a astigmatism. Ngakhale kuti dzinalo lingamveke lovuta, mayesowo ndi osavuta. Chomwe muyenera kuchita ndikuyang'ana chipangizo chapadera ndikuuza dokotala wanu nthawi yomwe zizindikiro zomwe zili pamenepo zikugwirizana. Iye adzagwiritsa ntchito miyeso imeneyo kuti ayesere kupindika kwa cornea yanu.

Kumbukirani, iyi si mayeso oti munthu apambane kapena alephere. Kaya vuto lanu la astigmatism ndi lalikulu bwanji, pali njira zolithetsera. Dokotala wanu wa maso adzakulangizani njira zabwino kwambiri zoyeretsera maso anu.

Choncho, musachite mantha ngati mwapemphedwa kuti muchite keratometry mukapita kukayezetsa maso. Ndikofunikira kwambiri pa thanzi la maso anu.
