Dzimwe nguva unonzwa sekunge nyika haina kujeka here? Paunenge uchityaira husiku, mwenje yemotokari dziri pamberi pako inoita kunge isina kujeka here? Kana kuti unonzwa sekunge hausi kuona zvakanaka kunyangwe uchishandisa magirazi ako here? Chimwe chezvikonzero zvikuru zveizvi chingave musiyano muchimiro chemaziso ako. Nhasi, tichataura nezvebvunzo iri nyore, isingarwadzi inogona kukubatsira kuwana mhinduro.
Chii chinonzi Keratometry?
Zita racho ringanzwika serakaoma, asi zviri nyore. Muchidimbu, keratometry inzira yekuyera kutenderera, kana chimiro, che cornea mumaziso ako.
Zvino ungave uchishamisika kuti cornea chii. Funga nezveziso redu sekamera yakanaka. Rutivi rwakajeka, rwakatetepa ruri pamberi pekamera iyi ndirwo rwatinoti cornea. Rwakafanana negirazi rinodzivirira riri pamusoro pelenzi yekamera pafoni yako. Chiedza chinopinda muziso redu kuburikidza necornea iyi. Saka, zvakakosha kuti chimiro checornea iyi chive chakarurama kuti uve nekuona kwakajeka. Kuongororwa kwekeratometry kunoyera chimiro ichocho.
Sei bvunzo iyi ichikosha? Chii chichawanikwa?
Dambudziko guru uye rinowanzoonekwa nebvunzo iyi iastigmatism . Iri idambudziko rinowanzoitika rinokonzera kusaona zvakanaka.
Ngatinzwisisei izvi zviri nyore.
Kazhinji, cornea yeziso rine hutano inoumbwa zvakanaka, sebaseball, kuitira kuti chiedza chinopinda muziso chitarise panzvimbo imwe chete, zvichitibvumira kuona mufananidzo wakajeka.
Asi chimiro che cornea yemunhu ane astigmatism hachisi denderedzwa rakakwana. Chinogona kunge chakarebeswa zvishoma, sebhora rerugby. Kana kuti chinogona kukombama kudivi rimwe, sekumashure kwechipunu. Kana izvi zvikaitika, chiedza chinopinda muziso hachina kutariswa panzvimbo imwe chete, asi munzvimbo dzinoverengeka. Ndosaka kuona kusina kujeka uye mifananidzo inoita seyakatambanudzwa.
Saka, chinangwa chikuru chebvunzo ye keratometry ndechekuona kana uine astigmatism, uye kana zvakadaro, kusvika padanho ripi.
Bvunzo iyi inokoshawo mune mamwe mamiriro ezvinhu akati wandei:
- Usati wapfeka magirazi ekuonana: Kuti usarudze magirazi ekuonana anokodzera ziso rako zvakakwana, unofanirwa kuziva zviyero chaizvo zve cornea yako.
- Usati wavhiyiwa cataract: Munguva yekuvhiyiwa uku, lenzi yekugadzira (IOL) inoiswa muziso. Kuyerwa uku kwekeratometry kwakakosha pakusarudza lenzi inonyatsokodzera ziso rako.
Bvunzo iyi yeKeratometry inoitwa sei?
Iyi bvunzo inokurumidza uye isingarwadzi. Inogona kuitwa panguva yekuongororwa kwemaziso nguva dzose. Hamufanirwe kusarudza zuva rakasiyana rekuongorora maziso enyu.
Mudziyo unonzi 'Keratometer' unoshandiswa pakuita izvi. Pakutanga, unotaridzika seteresikopu diki. Zvisinei, hautarise nyeredzi dziri kure, asi unotarisa maziso ako ari pedyo. Ngatitarisei nhanho nhanho kuti bvunzo yacho inoitwa sei.
| Matanho | Chii chiri kuitika? |
|---|---|
| 1. Kuzvigadzirira | Uchakumbirwa kugara pachigaro, kuisa chirebvu chako panzvimbo yakakosha pamuchina, uye kuisa huma yako padanda rakakosha. Izvi zvinoitirwa kuchengetedza musoro wako panzvimbo imwe chete panguva yekuongororwa. Chiremba achagadzirisa muchina wacho kuitira kuti ziso rako rive panzvimbo chaiyo. |
| 2. Kuona kuburikidza nemudziyo | Uchakumbirwa kuti utarise nepaburi diki riri mumuchina (eyepiece). Zvakafanana nekutarisa nepamabinoculars. Ungangodawo kuvhara rimwe ziso risiri kuongororwa panguva ino. |
| 3. Kutarisa mufananidzo uri mukati | Mukati memuchina, muchaona mufananidzo unoita semadenderedzwa matatu, kana mufananidzo une zviratidzo zvakanaka (+) uye zvakaipa (-). Munokurudzirwa kuti muutarise musingabwairi. |
| 4. Kurekodha zviyero | Paunenge uchitarisa mufananidzo iwoyo, chiremba ari kutenderedza mabhatani emuchina kuti agadzire mifananidzo iyoyo. Pane imwe nguva, zviratidzo zviviri izvozvo zvekuwedzera (+) zvinogumirana. Panguva iyoyo chaiyo, anonyora zviyero zvacho. |
| 5. Kutarisa rimwe ziso | Kana ziso rimwe rapera, rimwe ziso rinoedzwa nenzira imwecheteyo. Bvunzo yese inotora nguva pfupi, ingangoita maminetsi mashoma. |
Pane njodzi kana kuti zvakaipira bvunzo iyi here?
Kwete zvachose. Iyi bvunzo yakachengeteka 100% . Haikukonzere njodzi kana kurwadziwa . Kunyangwe chiedza chinobva mumuchina chakajeka zvishoma, hachizokuvadzi maziso ako kana kuona kwako.
Asi pane chinhu chimwe chete chidiki. Pane kuti izvi zvinzi "kushata," funga nezvazvo sekuziva rudzi rwebvunzo iyi. Kuongororwa kwekeratometry hakusi kuyera cornea yako zvizere, asi kufungidzira kwakanaka kwazvo.
Ndichatsanangura chikonzero nei zviri nyore. Funga nezvepasi. Rakatenderera zvakanaka uye rakatsetseka. Asi tinoziva kuti Pasi redu harina kunyatsotsetseka, kune makomo marefu seHimalayas, makungwa akadzika seMariana Trench, nezvimwe zvinhu zvakawanda zvakaita semipata. Uye Pasi harisi bhora rakakwana futi. Asi pasi rinobatsira zvikuru pakunzwisisa kuti Sri Lanka iri kupi uye kuti America iri kupi, handiti?
Kuongororwa kwekeratometry kwakafanana. Kunoyera chimiro che cornea yedu, tichifunga kuti ibhora rakakwana. Muchokwadi, maziso edu haasi mabhora akakwana, uye mune misiyano midiki maari. Asi chishandiso chinobatsira zvikuru uye chinokosha chekuona nekukurumidza uye nemazvo kana uine astigmatism.
Mazuva ano, vamwe vanachiremba vemaziso vanoshandisawo bvunzo dzepamusoro-soro, dzakadai se corneal mapping, izvo zvinogona kupa zviyero zvakanyatsonaka.
Ndezvipi izvi zvinoverengwa nekeratometry (K readings)?
Mhedzisiro yebvunzo iyi inonzi 'K readings' . Chiyero chezviyero izvi chinonzi diopters .
Usavhunduke nenhamba idzi neruzivo urwu. Izvi ndezvekuti chiremba wako azvinzwisise. Achatarisa mhinduro idzi obva aona chikonzero chaicho chekuchinja kwemaonero ako.
| Matambudziko eziso | Hunhu hwekuverenga kweK |
|---|---|
| Cornea ine hutano, yakatenderera (Normal Cornea) | Kornea yese ine kukosha kwakafanana kweK. Kazhinji, kukosha uku kunosvika ma diopters makumi mana nematatu. |
| Ziso rine astigmatism | Uchaona ma K maviri. Rimwe rechikamu chakanyanya kudzika che curve, uye rimwe rechikamu chakati sandara. Musiyano uripo pakati pema K maviri aya unoratidza kuti une astigmatism yakawanda. |
Kuverenga uku kweK kuchatungamira chiremba wako pakusarudza magirazi akakodzera, magirazi ekuonana, kana, kana zvichidikanwa, lenzi yakakodzera yekuvhiyiwa.
Ndinofanira kuona chiremba wangu rini?
Chiremba wako achakuudza kuti unofanira kuongororwa maziso ako kangani. Zvakakosha kutevedzera purogiramu iyoyo.
Chimiro chemaziso edu chinoshanduka nekufamba kwenguva, saka huwandu hweastigmatism hunogona kuchinja. Zvisinei, kana ukaona shanduko huru mukuona kwako, kunyanya kana isina kujeka kupfuura zvakajairika, usazviregeredza. Inogona kunge iri chiratidzo chechirwere chakaita sekeratoconus chinoda kurapwa nekukasika. Saka kana ukaona shanduko huru mukuona kwako, enda kuna chiremba wako nekukasika.
Yeuka, iyi haisi bvunzo yaunogona kupasa kana kukundikana. Ingori bvunzo yekuona kuti maziso ako ari kushanda zvakanaka sei. Kunyangwe astigmatism yako yakakura sei, uchiri kukwanisa kuona zvakajeka nemagirazi akakodzera, ma contact lenses, kana mamwe marapirwo.
Mharidzo Yekuenda Nayo Kumba
- Keratometry inzira iri nyore, isingarwadzi, uye yakachengeteka yekuyera kukombama kwe cornea yako.
- Izvi zvinonyanya kuratidza dambudziko rekuona rinowanzoonekwa rinonzi astigmatism.
- Mhedzisiro yebvunzo (K readings) ichabatsira chiremba wako kusarudza magirazi akanakisa, ma contact lenses, kana ma lenses epashure pekuvhiyiwa.
- Kana ukaona shanduko huru kana kuti isingatarisirwi mukuona kwako, usazviregeredza wobva waona chiremba wemaziso nekukasika.
