Reka twige bike ku ikizamini cya Keratometry, gipima uburyo amaso agoramye.

Iyo wigeze gupimwa amaso, ushobora kuba warabonye muganga areba amaso yawe agakoresha ibikoresho bitandukanye kugira ngo ayasuzume. Hari igihe twibaza tuti "Ibi bireba iki nanone?" Kimwe mu bipimo by'ingenzi nk'ibyo byitwa Keratometry. Uyu munsi, turaganira ku cyo ari cyo, impamvu bikorwa, n'uko bikorwa.

Keratometry ni iki?

Mu magambo make, keratometry ni ikizamini gipima uburyo cornea igoramye , igice cy’imbere cy’ijisho ryawe kigaragara kandi gifite uruziga. Icornea imeze nk’igipfundikizo gitwikiriye amaso yacu. Igoramye ryayo rikwiye ni ingenzi cyane kugira ngo umuntu abone neza.

Iki kizamini cya keratometry gipima iki?

Iki kizamini ahanini kigena niba ufite indwara yitwa astigmatism. Astigmatism ni ikosa rikunze kugaragara cyane ritera kutabona neza.

Tekereza, ijisho rizima rikunze kuba rizengurutse nk'umupira w'amaguru. Hanyuma, iyo urumuri rwinjiye mu jisho, rwibanda ahantu hamwe maze tukabona neza. Ariko ijisho ry'umuntu ufite astigmatism, ni ukuvuga cornea, rimeze nk'umupira wa rugby, cyangwa rirerire gato nk'inyuma y'ikiyiko, cyangwa rikagira ibara ry'uruhande rumwe. Hanyuma , iyo urumuri rwinjiye mu jisho, ntirwibanda ahantu hamwe, maze kureba biba bitoroshye. Iki kizamini cya keratometry gipima imiterere y'imboni.

Iki kizamini cya keratometry gikorwa gite? Biroroshye cyane!

Iki ni ikizamini cyihuse cyane kandi kitababaza. Inzobere mu by'amaso irashobora kugikorera mu biro bye. Ntabwo ari ngombwa kugiteganya umunsi cyangwa isaha byihariye. Bishobora gukorwa mu gihe cyo gupima amaso yawe buri gihe, cyangwa bishobora gukorwa ukwabyo niba muganga wawe akeka ko ufite indwara yo kubura amaso.

Nanone, niba ugiye kwambara indorerwamo aho kwambara indorerwamo, cyangwa niba witegura kubagwa cataract, nta kabuza uzakora iki kizamini cya keratometry.

Noneho reka turebe uko ibi bikorwa. Muganga akoresha igikoresho cyitwa keratometer . Kimeze nk'icyuma gipima ikirere. Ariko, ntikireba inyenyeri ziri kure, ahubwo kireba amaso yawe hafi cyane. Dore intambwe zo gukora ikizamini:

1. Uzasabwa kwicara, kandi keratometero ifite icyuma gishyigikira akananwa kawe n'aho ushyira agahanga kawe . Uko ushyira umutwe waweho, muganga azahindura igikoresho kugira ngo gihuze neza n'ijisho ryawe.

2. Hanyuma ubwirwa kureba imbere muri icyo gikoresho. Ni nko kureba mu byuma bireba kure. Hari igihe ubwirwa gufunga irindi jisho ritari gusuzumwa.

3. Muganga akubwira ibiri muri icyo gikoresho.Saba kureba ishusho. Akenshi igira uruziga eshatu, cyangwa ikintu gisa n'intego ifite ikimenyetso cyo kongeraho n'ikimenyetso cyo gukuraho.

4. Hanyuma, umuganga akoresha igikoresho buhoro buhoro , agenda azunguza intego hirya no hino, agaragaza ibimenyetso byiza aho bikoraho.

5. Iyo umubare umaze kugerwaho, muganga yandika ibipimo. Hanyuma, ahindura irindi jisho ry'igikoresho maze agapima iryo jisho muri ubwo buryo.

Tekereza nko guhindura aho kamera iherereye. Muganga arimo kureba kugira ngo arebe neza ko amashusho ajyanye n'imiterere y'ijisho ryawe.

Urabona? Biroroshye cyane, si byo se? Ushobora kurangiza iki kizamini mu minota mike gusa.

Ese hari ingaruka cyangwa ingaruka mbi kuri ibi?

Oya, nta ngaruka zihari. Umucyo uturuka kuri keratometero ushobora kuba mwinshi cyane iyo urebye, ariko ntuzangiza amaso yawe cyangwa kureba kwawe.

Ariko hari ikintu kimwe gito. Ni ukuvuga ko iki kizamini cya keratometry gitanga igereranya ry’imboni yawe, aho kuba igipimo nyacyo. Impamvu y’ibi ni uko iki kizamini gipima imboni yawe, dutekereza ko ari uruziga rwose, uruziga rumwe ahantu hose. Ariko mu by’ukuri, amaso ya buri wese afite itandukaniro rito karemano. Kubwibyo, imboni ntabwo imeze nk’uruziga.

Ariko ibyo ntibivuze ko iki kizamini ntacyo kimaze. Tekereza umubumbe ufite ikarita y'isi. Tuzi ko ubuso bw'Isi bufite imisozi, inyanja, n'imiterere itandukanye y'ubutaka, bityo ntabwo ari nziza, kandi ntabwo ari uruziga rwose. Ariko umubumbe ni igikoresho cyiza cyo kudufasha gusobanukirwa aho turi. Keratometry ni imwe. Nubwo atari igipimo nyacyo cy'inyuma y'umugongo, ni ingirakamaro cyane mu kumenya vuba kandi neza astigmatisme y'abantu benshi.

Bamwe mu baganga b'amaso ubu barimo gukoresha uburyo bwo gupima cornea (buzwi kandi nka corneal topography na corneal tomography) aho gukoresha keratometry. Ibi bigezweho kandi bitanga ibipimo nyabyo. Ubu birimo gukundwa cyane nk'uburyo bwo gusuzuma astigmatism. Muganga wawe ashobora kandi gukora ikizamini cyo gupima cornea kugira ngo yemeze ibyavuye mu kizamini cya keratometry.

Iyi nyandiko ya K ni iyihe? Ese hari agaciro gasanzwe?

Ibisubizo by'ikizamini cya keratometry byitwa gusoma kwa K. Abaganga b'amaso babipima mu bipimo byitwa diopters .

Ubusanzwe, cornea nzima ihindura urumuri ku gipimo cya diopta zigera kuri 43. Iyo cornea ifite icyerekezo gihanitse (corneas ndende), iki gipimo kiriyongera. Iyo icyerekezo ari gito (corneas ndende), iki gipimo kiragabanuka.

• Niba cornea yawe ari uruziga rwose, ifite agaciro ka K ku buso bwayo bwose.
• Ariko niba ufite astigmatism, cornea yawe izagaragaza agaciro ka K ebyiri . Kimwe ni agaciro ku gice kigoramye cyane, ikindi ni agaciro ku gice kigoramye cyane, kirambuye cya cornea. Ikizamini cya keratometry kigaragaza iri tandukaniro n'aho curvature iri hejuru cyane kandi iri hasi cyane.

Ibi bipimo bya K ni ingenzi cyane kuri muganga kugira ngo yandike uburyo cornea yawe igoroka. Ibi bipimo bifasha muganga kumenya icyatera impinduka mu maso yawe. Nanone, niba ukeneye kubagwa cataract, ibi bipimo bya K binakoreshwa mu guhitamo lens yo mu maso.

Ibi bisubizo n'imibare bishobora kugorana kubyumva. Ariko ntugahangayike. Muganga wawe w'amaso cyangwa umuganga ashobora kugufasha gusobanukirwa imiti uhabwa n'amaso. Bashobora kandi kugufasha guhitamo indorerwamo nziza, lentile zo mu maso, cyangwa ubundi buryo bwo gukosora amaso yawe.

Ni ryari twagombye kubonana n'umuganga w'amaso?

Inzobere mu by'amaso izakubwira inshuro ugomba kwipimisha amaso buri gihe.

Uko tugenda dusaza, amaso yacu ahinduka mu buryo busanzwe, bityo astigmatism ishobora guhinduka. Ariko, impinduka nini kandi zitunguranye muri astigmatism zishobora kuba ikimenyetso cy'indi ndwara igomba kuvurwa vuba, nka keratoconus. Rero, niba ubonye impinduka mu maso yawe cyangwa mu kureba - cyane cyane niba kureba kwawe bisa nkaho bitameze neza cyangwa bitagaragara neza - menya neza ko ugiye kubonana n'umuganga w'amaso ako kanya.

Amaherezo, ibintu byo kwibuka

Keratometry ni ikizamini gikunze gukoreshwa n'inzobere mu by'amaso kugira ngo bapime astigmatisme. Nubwo izina rishobora kumvikana nk'irigoye, ikizamini cyoroshye cyane. Icyo ugomba gukora ni ukureba igikoresho cyihariye hanyuma ukabwira muganga wawe igihe ibimenyetso biri kuri cyo bihuye. Azakoresha ibyo bipimo kugira ngo apime imiterere y'ijisho ryawe.

Wibuke ko iki atari ikizamini cyo gutsinda cyangwa gutsindwa. Uko ububabare bwawe bwaba bungana kose, hari uburyo bwo kugikosora. Muganga wawe w'amaso azagusaba uburyo bwiza bwo gusukura amaso yawe.

Ntugatinye rero niba usabwe gukora keratometry igihe ugiye kwisuzumisha amaso. Ni ingenzi cyane ku buzima bw'amaso yawe.
