Ngatidzidzei zvishoma nezve Keratometry test, iyo inoyera kukombama kwemaziso.

Kana wakamboongororwa maziso, pamwe wakaona chiremba achitarisa maziso ako uye achishandisa zvishandiso zvakasiyana-siyana kuti aaongorore. Dzimwe nguva tinoshamisika kuti, "Chii ichi chiri kutarisa zvakare?" Imwe bvunzo yemaziso yakakosha inonzi Keratometry. Nhasi, tichataura nezvei, kuti nei ichiitwa, uye kuti inoitwa sei.

Chii chinonzi Keratometry?

Zvichitaurwa zviri nyore, keratometry bvunzo inoyera kukombama kwechisikigo kwe cornea , chikamu chakajeka, chakatenderera chepamberi peziso rako. Cornea yakaita sechifukidziro chakajeka pamusoro pemaziso edu. Kukombama kwayo kwakakodzera kwakakosha zvikuru kuti tione zvakajeka.

Chii chinoonekwa nebvunzo iyi ye keratometry?

Kuongororwa uku kunonyanya kuratidza kana uine chirwere chinonzi astigmatism. Astigmatism chikanganiso chinowanzoitika chekusaona zvakanaka chinokonzera kusaona zvakanaka.

Fungidzira, ziso rine hutano rinowanzoita rakatenderera sebhora rebaseball. Zvadaro, kana chiedza chikapinda muziso, chinotarisisa panzvimbo imwe uye tinoona zvakajeka. Asi ziso remunhu ane astigmatism, kureva cornea, rakaita sebhora rerugby, kana kuti rakareba zvishoma semusana wechipunu, kana kuti rakakombama kune rumwe rutivi. Zvadaro , kana chiedza chikapinda muziso, hachitarisi panzvimbo imwe chete, uye kuona kunova kusina kujeka. Iyi test keratometry inoyera kutenderera kwecornea.

Bvunzo iyi yekeratometry inoitwa sei? Zviri nyore kwazvo!

Iyi bvunzo inokurumidza uye isingarwadzi. Chiremba wemaziso wako anogona kuzviita muhofisi make. Hamufanirwe kuronga zuva kana nguva yakasarudzika yekuongororwa kwemaziso. Izvi zvinogona kuitwa panguva yekuongororwa kwemaziso nguva dzose, kana kuti zvinogona kuitwa zvakasiyana kana chiremba wako achifungidzira kuti une astigmatism.

Uyewo, kana uchizopfeka ma contact lenses panzvimbo pemagirazi, kana kuti uri kugadzirira kuvhiyiwa kwe cataract, zvechokwadi uchaita bvunzo iyi ye keratometry.

Zvino ngationei kuti izvi zvinoitwa sei. Chiremba anoshandisa mudziyo unonzi keratometer . Unotaridzika seteresikopu. Zvisinei, hautarise nyeredzi dziri kure, asi maziso ako ari pedyo. Heano matanho ekuyedza:

1. Uchakumbirwa kugara pasi, uye keratometer ine rutsigiro rwechirebvu chako nenzvimbo yekutsamira huma yako . Paunoisa musoro wako pairi, chiremba achagadzirisa mudziyo wacho kuti ukwane neziso rako zvakanaka.

2. Wobva waudzwa kuti utarise mukati memudziyo. Zvakafanana nekutarisa nemabhainokura. Dzimwe nguva unoudzwa kuti uvhare rimwe ziso risiri kuongororwa.

3. Chiremba anokuudza zviri mukati memudziyo.Vakumbire kuti vatarise mufananidzo. Kazhinji une madenderedzwa matatu, kana chimwe chinhu chakaita sechinangwa chine chiratidzo chekuwedzera nechiratidzo chekubvisa.

4. Zvadaro, chiremba anochinja-chinja mudziyo zvishoma nezvishoma , achifambisa zvinhu zvinonangwa, achiunza zviratidzo zvakanaka kusvika pakubatana.

5. Kana nhamba yacho yasvika, chiremba anonyora zviyero zvacho. Zvadaro, anogadzirisa rimwe ziso remuchina uye anoedza ziso iroro nenzira imwecheteyo.

Funga nezvazvo sekugadzirisa kutarisa kwekamera. Chiremba ari kutarisa kuti ave nechokwadi chekuti mifananidzo yacho inoenderana nekombamo ye cornea yako.

Waona? Zviri nyore kwazvo, handiti? Unogona kupedzisa bvunzo iyi mumaminitsi mashoma chete.

Pane zvazvakaipira here kana kuti njodzi dziripo panyaya iyi?

Kwete, hapana njodzi. Chiedza chinobva kukeratometer chingave chakajeka zvishoma paunotarisa, asi hachizokuvadzi maziso ako kana kuona kwako.

Asi pane chinhu chimwe chidiki. Kureva kuti, bvunzo iyi yekeratometry inopa fungidziro yekufungidzira kwe cornea yako, kwete chiyero chaicho. Chikonzero cheizvi ndechekuti bvunzo iyi inoyera cornea yako, tichifunga kuti yakatenderera zvakakwana, yakatenderera zvakafanana kwese kwese. Asi muchokwadi, maziso emunhu wese ane shanduko diki dzechisikigo. Saka, cornea haina kufanana nebhora.

Asi izvozvo hazvirevi kuti bvunzo iyi haina zvainobatsira. Fungidzira pasi rose rine mepu yenyika. Tinoziva kuti pamusoro peNyika pane makomo, makungwa, nenzvimbo dzakasiyana-siyana, saka harina kutsetseka, uye harina kutenderera chaiko. Asi pasi rose chishandiso chakanaka chekutibatsira kunzwisisa kuti tiri papi. Keratometry yakafanana. Kunyangwe isiri chiyero chaicho che cornea, inobatsira zvikuru pakuona nekukurumidza uye nemazvo astigmatism yevanhu vazhinji.

Vamwe vanachiremba vemaziso vava kushandisa corneal mapping (inozivikanwawo se corneal topography uye corneal tomography) pachinzvimbo che keratometry. Izvi zvave zvemhando yepamusoro uye zvinopa zviyero zvakarurama. Iye zvino zvava kufarirwa senzira yekuongorora astigmatism. Chiremba wako anogonawo kuita corneal mapping test kuti asimbise mhedzisiro ye keratometry test.

Kuverenga uku kwaK chii? Pane kukosha kwakajairika here?

Mhedzisiro yebvunzo yekeratometry inonzi kuverenga kweK . Vanachiremba vemaziso vanoyera izvi muzvikamu zvinonzi diopters .

Kazhinji, cornea ine hutano inochinja chiedza nehukuru hwema diopters angangoita 43. Kana cornea ine curve yakakombama (steep corneas), kukosha uku kunowedzera. Kana curve iri shoma (flatter corneas), kukosha uku kunoderera.

• Kana cornea yako yakatenderera zvakakwana, ine kukosha kwakafanana kweK pamusoro payo yese.
• Asi kana uine astigmatism, cornea yako icharatidza ma K maviri . Imwe ndiyo kukosha kwechikamu chakakombama zvakanyanya, uye imwe ndiyo kukosha kwechikamu chakakombama zvishoma, chakati sandara checornea. Kuongororwa kwekeratometry kunoratidza musiyano uyu uye kuti curvature iri pakakwirira uye pasi.

Kuverengwa kweK uku kwakakosha kuti chiremba anyore kukombama kwe cornea yako. Kuyerwa uku kunobatsira chiremba kuziva chiri kukonzera shanduko mukuona kwako. Zvakare, kana uchida kuvhiyiwa cataract, kuverenga uku kweK kunoshandiswawo kusarudza lenzi yemukati meziso.

Mhedzisiro iyi nenhamba zvinogona kukuomera kunzwisisa. Asi musazvidya moyo. Chiremba wemaziso kana chiremba vanogona kukubatsirai kunzwisisa mushonga wemaziso enyu. Vanogonawo kukubatsirai kusarudza magirazi akanakisisa, magirazi ekuona, kana imwe nzira yekugadzirisa maziso enyu.

Tinofanira kuona chiremba wemaziso rini?

Chiremba wemaziso achakuudza kuti unofanira kuongororwa maziso kangani nguva nenguva.

Sezvatinokura, maziso edu anochinja chimiro, saka astigmatism inogona kuchinja. Zvisinei, shanduko huru, dzinongoerekana dzaitika mu astigmatism dzinogona kuva chiratidzo cheimwe chirwere chinoda kurapwa nekukurumidza, senge keratoconus. Saka, kana ukaona chero shanduko mumaziso ako kana kuona kwako - kunyanya kana kuona kwako kuchiita sekusina kunaka pane zvakajairika kana kusina kujeka - iva nechokwadi chekuona chiremba wemaziso nekukasika.

Pakupedzisira, zvinhu zvekurangarira

Keratometry inzira inoshandiswa nevanyanzvi vemaziso kuongorora astigmatism. Kunyange zvazvo zita racho ringanzwika serakaoma, nzira yacho iri nyore. Chaunongofanira kuita kutarisa mudziyo chaiwo woudza chiremba wako kana zviratidzo zviri pairi zvakabatana. Iye achashandisa zviyero izvozvo kuyera kutenderera kwe cornea yako.

Yeuka, iyi haisi bvunzo yekupasa kana kukundikana. Kunyangwe astigmatism yako yakanyanya sei, kune nzira dzekugadzirisa. Chiremba wemaziso ako achakurudzira nzira dzakanakisa dzekuchenesa kuona kwako.

Saka, usatya kana ukakumbirwa kuti uite keratometry paunenge uchienda kunoongororwa maziso. Zvakakosha zvikuru pahutano hwemaziso ako.
