Ese hari igihe wumva isi iri mu kantu gato k’umuraba? Iyo utwaye imodoka nijoro, amatara y’imodoka ziri imbere yawe asa n’aho ari mu kantu gato k’umuraba? Cyangwa wumva utabona neza nubwo waba ukoresha indorerwamo zawe? Imwe mu mpamvu nyamukuru zishobora gutuma ibi bibaho ni itandukaniro rito mu miterere y’amaso yawe. Uyu munsi, tugiye kuvuga ku ikizamini cyoroshye kandi kidatera ububabare gishobora kugufasha kubimenya.
Keratometry ni iki?
Izina rishobora kumvikana nk'aho rigoye, ariko mu by'ukuri ryoroshye cyane. Muri make, keratometry ni ikizamini gipima imiterere y'ijisho ry'amaso yawe.
Noneho ushobora kuba wibaza icyo cornea ari cyo. Tekereza ijisho ryacu nk'ishusho nziza. Urusobe rw'amaso rubonerana kandi ruto ruri imbere y'iyi kamera ni cyo twita cornea. Ni nk'ikirahure kiri hejuru y'ikirahure cya kamera kuri telefoni yawe. Umucyo winjira mu jisho ryacu unyuze muri iyi cornea. Rero, ni ngombwa cyane ko imiterere y'iyi cornea iba ikwiye kugira ngo ibone neza. Ikizamini cya keratometry gipima iyo shusho.
Kuki iki kizamini ari ingenzi? Kizagaragaza iki?
Indwara nyamukuru kandi ikunze kugaragara cyane muri iki kizamini ni astigmatism . Iyi ni indwara ikunze kugaragara cyane itera kutabona neza.
Reka tubisobanukirwe mu buryo bworoshye.
Ubusanzwe, imboni y'ijisho rizima iba ifite imiterere myiza, nk'umupira w'amaguru, ku buryo urumuri rwinjira mu jisho rureba ahantu hamwe, bigatuma tubona ishusho isobanutse neza.
Ariko imiterere y'ijisho ry'umuntu ufite ikibazo cyo kutagira ubwenge si uruziga rutunganye. Rishobora kuba rirerire gato, nk'umupira wa rugby. Cyangwa rishobora kuba rigoramye ku ruhande rumwe, nk'inyuma y'ikiyiko. Iyo ibi bibaye, urumuri rwinjira mu jisho ntirureba ahantu hamwe, ahubwo rureba ahantu henshi. Niyo mpamvu kureba biba bitagaragara neza kandi amashusho asa n'aho ari make.
Rero, intego nyamukuru y'ikizamini cya keratometry ni ukumenya neza niba ufite astigmatism, kandi niba ari yo, ku rugero rungana iki.
Iki kizamini ni ingenzi no mu bindi bihe bitandukanye:
- Mbere yo kwambara lenzi zo mu maso: Kugira ngo uhitemo lenzi ijyanye neza n'ijisho ryawe, ugomba kumenya neza ibipimo by'ijisho ryawe.
- Mbere yo kubagwa katarakte: Muri iki gikorwa cyo kubaga, hashyirwamo lenzi y'ubukorano (IOL) mu jisho. Ibi bipimo bya keratometry ni ingenzi kugira ngo uhitemo lenzi ikwiranye neza n'ijisho ryawe.
Iki kizamini cya Keratometry gikorwa gite?
Iki ni ikizamini cyihuse cyane kandi kitababaza. Kirashobora gukorwa mu gihe cyo kwipimisha amaso yawe buri gihe. Ntabwo ari ngombwa kugiteganya umunsi utandukanye.
Igikoresho cyitwa 'Keratometer' gikoreshwa kuri ibi. Ukirebye bwa mbere, gisa nka telesikope nto. Ariko, ntikireba inyenyeri ziri kure, ahubwo kireba amaso yawe hafi cyane. Reka turebe intambwe ku yindi uko ikizamini gikorwa.
| Intambwe | Ni iki kiri kuba? |
|---|---|
| 1. Kwitegura | Uzasabwa kwicara mu ntebe, gushyira akananwa kawe ahantu hihariye kuri mashini, hanyuma ugashyira agahanga kawe ku kabati kadasanzwe. Ibi ni ukugira ngo umutwe wawe ugumane ahantu hamwe mu gihe cyo gupimwa. Nyuma yaho, muganga azahindura mashini kugira ngo ijisho ryawe ribe mu mwanya ukwiye. |
| 2. Kureba ukoresheje igikoresho | Uzasabwa kureba unyuze mu mwobo muto uri muri iyo mashini (ijisho). Ni nko kureba unyuze mu bireba kure. Ushobora kandi gufunga irindi jisho ritari gusuzumwa muri iki gihe. |
| 3. Kureba ishusho iri imbere | Imbere muri mashini, uzabona ishusho isa n'uruziga eshatu, cyangwa ifoto ifite ibimenyetso byiza (+) na bibi (-). Uragirwa inama yo kuyireba udahumbya amaso. |
| 4. Gupima ibipimo | Mu gihe ureba iyo shusho, muganga arimo arazunguza udupfundo tw’imashini kugira ngo akore ayo mashusho. Hari aho ibimenyetso bibiri byongeweho (+) bikoraho. Muri ako kanya, yandika ibipimo. |
| 5. Gusuzuma ijisho ry'irindi | Iyo ijisho rimwe rimaze kurangira, irindi jisho ripimwa muri ubwo buryo. Ikizamini cyose kimara igihe gito cyane, nk'iminota mike. |
Ese hari ingaruka cyangwa ingaruka mbi kuri iki kizamini?
Oya rwose. Iki ni ikizamini cyizewe 100% . Nta ngaruka cyangwa ububabare bigutera . Nubwo urumuri rw'imashini rumurika gato, ntabwo ruzangiza amaso yawe cyangwa kureba kwawe.
Ariko hari ikintu kimwe gito. Aho kwita ibi "ibibi," tekereza ko ari ukumenya imiterere y'iki kizamini. Ikizamini cya keratometry si igipimo nyacyo 100% cy'ishusho y'amaso yawe, ahubwo ni isuzuma ryiza cyane.
Ndasobanura impamvu mu buryo bworoshye. Tekereza ku isi. Ifite uruziga rwiza kandi rurerure. Ariko tuzi ko Isi yacu idasesuye cyane, hari imisozi miremire nka Himalaya, inyanja ndende nka Mariana Trench, n'ibindi bintu byinshi nk'ibibaya. Kandi Isi nayo si uruziga rutunganye. Ariko isi ni ingirakamaro cyane mu gusobanukirwa aho Sri Lanka iri n'aho Amerika iri, si byo se?
Ikizamini cya keratometry gisa n'icyo. Gipima imiterere ya cornea yacu, dutekereje ko ari uruziga rutunganye. Mu by'ukuri, amaso yacu si uruziga rutunganye, kandi hari itandukaniro rito muri yo. Ariko ni igikoresho cy'ingirakamaro cyane kandi cy'agaciro mu kumenya vuba kandi neza niba ufite astigmatism.
Muri iki gihe, bamwe mu baganga b'amaso bakoresha ibizamini bigezweho, nko gukoresha ikarita y'ishusho y'amaso, bishobora gutanga ibipimo nyabyo.
Ibi bipimo bya keratometry (ibipimo bya K) ni ibihe?
Ibisubizo by'iki kizamini byitwa 'ibipimo bya K' . Igice cyo gupima ibi byitwa diopters .
Ntugahangayikishwe n'iyi mibare n'ibisobanuro birambuye. Ibi ni ibyo muganga wawe agomba gusobanukirwa. Azareba ibi bisubizo maze amenye impamvu nyayo y'impinduka mu maso yawe.
| Indwara y'amaso | Imiterere y'isomwa rya K |
|---|---|
| Imboni nziza kandi izengurutse (Cornea isanzwe) | Kornea yose ifite agaciro ka K kamwe kandi kadahinduka. Ubusanzwe, iki gipimo ni diopta zigera kuri 43. |
| Ijisho rifite astigmatism | Uzabona agaciro ka K kari hagati y’igice kinini cyane cy’umurongo, n’ikindi hagati y’igice giteye neza kurusha ibindi. Itandukaniro riri hagati y’aka gaciro kari hagati y’aka gace k’umurongo n’igice cy’umurongo rigaragaza urwego rw’uburangare. |
Iyi nyandiko ya K izafasha muganga wawe guhitamo indorerwamo zikwiye, lenzi zo mu bwoko bwa contact lenses, cyangwa se, nibiba ngombwa, lenzi ikwiye yo kubagwa.
Ni ryari ngomba kubonana na muganga wanjye?
Muganga wawe azakubwira inshuro ugomba gusuzumwa amaso yawe. Ni ngombwa gukurikiza iyo gahunda.
Imiterere y'amaso yacu irahinduka mu buryo busanzwe uko igihe kigenda gihita, bityo urwego rwa astigmatism rushobora guhinduka. Ariko, niba ubonye impinduka zitunguranye kandi zikomeye mu kureba kwawe, cyane cyane niba zidasobanutse neza kurusha uko bisanzwe, ntubyirengagize. Bishobora kuba ikimenyetso cy'indwara nka keratoconus isaba kuvurwa vuba. Niba rero ubonye impinduka zitunguranye kandi zikomeye mu kureba kwawe, hita ubonana na muganga wawe.
Wibuke ko iki atari ikizamini ushobora gutsinda cyangwa gutsindwa. Ni ikizamini cyo kureba uko amaso yawe ameze. Uko astigmatisme yawe yaba ikomeye kose, uracyashobora kubona neza ukoresheje indorerwamo zikwiye, lentile zo mu bwoko bwa contact, cyangwa ubundi buryo bwo kuvura.
Ubutumwa bwo kujyana mu rugo
- Keratometry ni ikizamini cyoroshye, kidatera ububabare, kandi cyizewe cyo gupima imiterere y'ijisho ry'umura wawe.
- Ibi ahanini bigaragaza ubumuga busanzwe bwo kutabona bwitwa astigmatism.
- Ibisubizo by'ikizamini (ibipimo bya K) bizafasha muganga wawe guhitamo indorerwamo nziza, lentile zo mu bwoko bwa contact, cyangwa lentile zo mu bwoko bwa nyuma yo kubagwa.
- Niba ugize impinduka itunguranye cyangwa ikomeye mu kureba kwawe, ntubyirengagize ahubwo hita ubonana na muganga w'amaso.
