Wakambozvibvunza here kuti tinoona sei nyika zvakajeka kudaro? Chikonzero chikuru cheizvi iganda rakajeka, rakatetepa riri pamberi pemaziso edu. Chikamu ichi, chinoshanda segirazi rekamera, chinonzi "Cornea". Kana chimiro chekonea iyi chikachinja zvishoma, zvatinoona zvinogona kusviba uye kukanganiswa. Muzviitiko zvakadaro, tinozvidaidza kuti 'Corneal Topography', bvunzo inokosha uye isingarwadzi yekutarisa chimiro chaicho chekonea yako.
Zvichitaurwa zviri nyore, chii chinonzi Corneal Topography?
Zita iri ringanzwika serisinganzwisisike. Tinowanzo shandisa izwi rekuti "topography" mune zvejogirafi, zvinoreva kugadzira mamepu anoratidza pamusoro penyika, chimiro chemakomo, mipata, nzizi, nezvimwewo. Saka unodhirowa sei mepu nemaziso?
Fungidzira kuti cornea yako yakaita sechitsuwa chidiki. Dzimwe nzvimbo dzepamusoro pechitsuwa ichi dzakareba, dzimwe nzvimbo dzakaderera, uye dzimwe nzvimbo dzinogona kunge dzine maburi. Asi hatigoni kuona shanduko idzi nemaziso edu. Ndosaka nzira inonzi `Corneal Topography` ichishandiswa. Chainoita ndechekuti, inoshandisa mudziyo wekombuta wakakosha kugadzira mepu ye cornea yako ine mativi matatu (3D) . Mepu iyi inoratidzwa neruvara. Nemavara iwayo, tinogona kuona chaizvo kuti cornea yakakwira kupi, kuti yakati sandara kupi, kuti yakatetepa kupi, uye kuti yakakora kupi.
Zvichitaurwa zviri nyore, izvi zvakafanana nekutorwa kwemifananidzo yemaziso ako. Hapana kurwadziwa, uye hapana chinobata maziso ako.
Sei tichida bvunzo iyi?
Bvunzo iyi inoita mabasa akakosha mukurapa maziso. Pane zvikonzero zvikuru zvitatu.
1. Ziva zvirwere zvemaziso uye tarisa kufambira mberi kwazvo
Zvimwe zvirwere zvemaziso zvinokanganisa zvakananga chimiro uye ukobvu hwe cornea. Kuongororwa uku kwakakosha pakuongorora zvirwere zvakadaro.
- Astigmatism: Chirwere chekuti cornea haina kutenderera zvakakwana, asi yakarebesa zvishoma, sezai. Izvi zvinogona kukonzera kusaona zvakanaka.
- Keratoconus: Ichi chirwere chakakomba zvishoma. Chinoitika pano ndechekuti cornea inotetepa zvishoma nezvishoma uye inobuda mberi sekoni. Kuongororwa kwe `Corneal Topography` kwakakosha zvikuru kuti zvionekwe izvi pakutanga.
- Kuora kweganda kwemaziso (PMD): Ukuwo kunovawo kutetepa kwe cornea.
- Mavanga anokonzerwa nekukuvara kana hutachiona: Kana paine vanga pa cornea, unogona kuona kuti rinokanganisa sei kuona.
- Pterygium: Chirwere chekuti kukura kwenyama kunobva paganda jena reziso kuenda ku cornea.
2. Ronga kuvhiyiwa uye tarisa mhedzisiro
Kuongororwa uku kwakakosha pakuvhiyiwa kwemaziso, kunyanya kuvhiyiwa kwe cornea.
- Kuvhiyiwa kwekugadzirisa kuona neLaser (LASIK kana PRK): Vanhu vazhinji vanoda kubvisa magirazi kana ma contact lenses nekuvhiyiwa `(LASIK)`. Asi havasi vese vanogona kuvhiyiwa uku. Kuongororwa uku kunoitwa kuti kuve nechokwadi chekuti chimiro neukobvu hwe cornea yako zvakakodzera kuvhiyiwa uku. Sezvambotaurwa, chirwere chakadai se`(Keratoconus)` chinogona kuonekwa kunyangwe chisina zviratidzo. Kana `(LASIK)` ikaitwa kuvanhu vakadaro, matambudziko akakomba anogona kuitika.
- Kuvhiyiwa kweCataract: Pakubvisa cataract uye kuisa lenzi yekugadzira, ruzivo nezve chimiro checornea rwakakosha kuti uverenge simba relenzi iyoyo nemazvo.
- Kuvhiyiwa kwekuisirwa cornea: Kuongororwa uku kunobatsira kuona mamiriro ecornea yakakuvara isati yatsiviwa neimwe itsva uye mushure mekunge yatsiviwa neimwe.
- Kuvhiyiwa kweCorneal cross-linking: Kuvhiyiwa kwekusimbisa cornea yave kushaya simba nekuda kwezvirwere zvakaita se`(Keratoconus)`. Kuongororwa uku kunodiwawo kuronga kuvhiyiwa uku.
3. Sarudza magirazi anokodzera maziso ako zvakakwana.
Kuongororwa uku hakudiwi nguva dzose kuti uise lenzi yekuonana yakajairika. Zvisinei, kana cornea yako ine chimiro chisina kujairika, senge Keratoconus, lenzi dzekuonana dzakajairika hadzishande. Kana zvakadaro, uchafanirwa kushandisa lenzi dzekuonana dzakasimba (Rigid gas-permeable - RGP lenses) . Kuti lenzi yakadaro ikwane ziso rako zvakakwana, kuyerwa kwese kwe cornea kunofanirwa kutorwa uye lenzi inofanira kugadzirwa kuti ikwane. Mepu yakawanikwa kubva kuCorneal Topography inobatsira zvikuru pane izvi.
Ndiani anoda kunyora bvunzo iyi?
Ungave uchinetseka kana uchida bvunzo iyi. Vanachiremba vanowanzokurudzira bvunzo iyi mumamiriro ezvinhu anotevera.
| Mamiriro ezvinhu | Chikonzero |
|---|---|
| Kana uri kufunga nezvekuvhiyiwa ne laser (senge LASIK) | Iva nechokwadi chekuti cornea yako yakakodzera kuvhiyiwa uye kuti hapana zvirwere zvakavanzika. Iri idanho rinosungirwa. |
| Kana uchida kuvhiyiwa kwechirwere che cornea | Zvinobatsira chiremba kuronga kuvhiyiwa nemazvo uye kuwana mhedzisiro yakanaka. |
| Kana wakambovhiyiwa maziso | Tarisa mhedzisiro yekuvhiyiwa uye kuti chimiro che cornea chakachinja sei. |
| Kana uchida magirazi ekuonana akakosha | Sarudza lenzi inonyaradza inokodzera zvakakwana cornea ine chimiro chisina kujairika. |
Bvunzo iri nyore kwazvo!
Unofanira kugadzirira bvunzo usati waitwa here?
Kazhinji, hapana kugadzirira kwakakosha kunodiwa. Zvisinei , kana ukapfeka ma contact lenses, chiremba wako achakuudza kuti urege kuapfeka mazuva mashoma, kana kunyange mavhiki, bvunzo isati yaitwa. Izvi zvinodaro nekuti kupfeka ma lenses kunogona kuchinja chimiro chechisikigo che cornea yako (corneal warpage). Saka kuti uwane zviyero zvakarurama, unofanirwa kumirira kusvika cornea yako yadzokera pachimiro chayo chechisikigo.
Chii chinoitika panguva yebvunzo?
Maitiro ese aya anotora maminetsi mashoma chete.
1. Unogara pachigaro pamberi pemuchina unoita sebhora guru.
2. Huru yako nechirebvu zvinoiswa munzvimbo dzakatarwa uye zvinoudzwa kuti zvigare zvakanaka.
3. Zvadaro vanokumbirwa kuti vatarise zvakananga pane chiedza chiri mukati mebhora.
4. Paunenge wakamirira, muchina unotora mifananidzo yakawanda yemaziso ako pasina ruzha kana kurwadziwa.
5. Mifananidzo inotorwa inoongororwa nekombiyuta yoshandurwa kuita mamepu emavara ataurwa pamusoro apa.
Ndizvozvo chete! Hauzonzwi chero chinhu. Muchina wacho hautombobati maziso ako . Zvakafanana nekutora mufananidzo.
Mhedzisiro yebvunzo... mamepu ane mavara!
Mushure mekuongororwa, chiremba wako achakupa mamepu ane mavara akasiyana-siyana. Kana ukaona aya, ungasakwanisa kuona kuti ndeapi. Asi ruvara rumwe nerumwe nenhamba imwe neimwe zvine zvazvinoreva.
Kazhinji, mavara anodziya akadai setsvuku neorenji anoratidza nzvimbo dzakakwirira/dzakabudikira dze cornea . Mavara anotonhorera akadai sebhuruu negirini anoratidza nzvimbo dzakati sandara/dzakaderera dze cornea .
Zvichienderana neruzivo rwunodiwa nachiremba, mhando dzakasiyana dzemamepu dzinogona kuwanikwa.
| Rudzi rweMepu | Izvi zvinotiratidzei? |
|---|---|
| Mepu yeAxial (Mepu yeSagittal) | Iyi ndiyo mepu inonyanya kushandiswa. Inoratidza kukombama kwe cornea, kureva, nzvimbo dzakakwirira nedzakaderera (semakomo nemipata). Mu cornea ine hutano, mepu iyi inowanzova yegirini. |
| Mepu Yekukwira | Izvi zvinoenzanisa cornea yako ne "chimiro chakajairika" chakagadzirwa nekombuta. Mavara anodziya anoratidza nzvimbo dzakakwirira kupfuura chimiro chakajairika. Mavara anotonhora anoratidza nzvimbo dziri pasi pechimiro chakajairika. |
| Mepu yeKukora kweCorneal (Mepu yePachymetry) | Mepu iyi inoratidza ukobvu hwe cornea. Mavara anodziya (akaita setsvuku) anoratidza nzvimbo dzakatetepa, uye mavara anotonhorera (akaita sebhuruu) anoratidza nzvimbo dzakatetepa. Mepu iyi yakakosha pakuongorora zvirwere zvakaita se keratoconus, uko cornea inotetepa. |
Usavhunduke nemamepu aya ane mavara. Ibasa rachiremba wako kuongorora ruzivo rwuri pamamepu aya nemazvo uye kupa tsananguro yechirwere chako. Mubvunze chero mibvunzo yaungave nayo.
Izvi zvakachengeteka here? Ndinofanira kutaura nachiremba riini?
Ehe. Corneal Topography bvunzo yakachengeteka zvizere. Hapana njodzi dzinozivikanwa kana migumisiro yakaipa. Ibvunzo zvakare isingarwadzi uye inokurumidza.
Kana muine mibvunzo nezvemhedzisiro yenyu yekuongororwa, kana kana zviratidzo zvemaziso enyu (zvakadai sekuona kusina kunyatsojeka, kurwadziwa) zviri zvitsva kana kuti zvichiwedzera kuipa, shanyirai chiremba wenyu nekukasika.
Mharidzo Yekuenda Nayo Kumba
- Kuongororwa kweCorneal Topography inzira isingarwadzi uye yakachengeteka inogadzira mepu ye3D yecornea (chikamu chinoonekera chiri pamberi peziso rako).
- Izvi zvakakosha pakuongorora zvirwere zvakaita se'Keratoconus' uye 'Astigmatism', uye kuona kana wakakodzera kuvhiyiwa nelaser senge 'LASIK'.
- Izvi zvinobatsira kugadzira magirazi ekuonana akasarudzika emakona asina chimiro chisina kujairika.
- Mhedzisiro yebvunzo inoratidzwa muchimiro chemamepu emavara. Chiremba wako achakutsanangurira zvinoreva izvi nemashoko akareruka.
- Kana muine mibvunzo nezvebvunzo iyi kana mhedzisiro, musatya kubvunza chiremba wenyu.
