Sɔntɛnde yu kin fil lɛk se di wɔl nɔ klia smɔl? We yu de drayv na nɛt, yu tink se di layt dɛn na motoka dɛn we de bifo yu kin tan lɛk se dɛn nɔ klia smɔl? Ɔ yu kin fil lɛk se yu nɔ ebul fɔ si klia wan ivin we yu de yuz yu glas? Wan pan di men rizin fɔ dis kin bi we yu yay difrɛn smɔl. Tide, wi go tɔk bɔt wan simpul tɛst we nɔ gɛt pen ɛn we go ɛp yu fɔ no.
Wetin na Keratometry?
Di nem kin tan lɛk se i kɔmplikt smɔl, bɔt fɔ tru, i rili simpul. Fɔ tɔk am simpul wan, keratometry na tɛst we de sho aw di kɔnia kɔba ɔ shep na yu yay.
Naw yu go de wɔnda wetin na di kɔnia. Tink bɔt wi yay lɛk gud kamɛra. di transparent, tin layt we de bifo dis kamɛra na in wi kɔl di kɔnia. I tan lɛk di glas we de protɛkt yu oba di kamɛra lens na yu fon. Layt kin go insay wi yay tru dis kɔnia. so, i rili imכtant fכ di shep fכ dis kכnia fכ kכrekt fכ mek i gεt klia vishכn. Di keratometry test de mɛzhɔ da shep de.
Wetin mek dis tɛst impɔtant? Wetin i go fɛn?
di men εn mכst kכmכn kכndyushכn we dis tεst de dεtekt na astigmatism . Dis na wan sik wae kin pasmak wae kin mek yu nɔr de si fayn fayn wan.
Lɛ wi ɔndastand dis mɔ simpul wan.
Nɔmal wan, di kɔnia na di yay we gɛt wɛlbɔdi kin shep fayn fayn wan, lɛk baysbɔl, so dat di layt we de go insay di yay kin de na wan say, ɛn dis kin mek wi ebul fɔ si klia pikchɔ.
Bɔt di shep fɔ di kɔnia fɔ pɔsin we gɛt astigmatism nɔto pafɛkt sɛklɔ. I kin lɔng smɔl, lɛk rɔgbi bɔl. Ɔ i kin kɔba to wan say, lɛk di bak pat pan spun. We dis kin apin, di layt we de go insay di yay nɔ kin de na wan ples, bɔt i kin de na bɔku say dɛn. Na dat mek di vishɔn nɔ kin klia ɛn di pikchɔ dɛn kin tan lɛk se dɛn strɛch.
So, di men tin we mek yu de du keratometry test na fɔ no if yu gɛt astigmatism, ɛn if na so, to us digri.
Dis tɛst impɔtant bak pan sɔm ɔda tin dɛn:
- Bifo yu put kɔntakt lens: Fɔ pik kɔntakt lens we fit yu yay fayn fayn wan, yu nid fɔ no di rayt we aw yu kɔnia de mɛzhɔ.
- Bifo dɛn du di ɔpreshɔn pan di katarakt: We dɛn de du dis ɔpreshɔn, dɛn kin put atifishal lens (IOL) insay di yay. Dɛn keratometry mɛzhɔmɛnt ya impɔtant fɔ pik di lens we go fit yu yay fayn fayn wan.
Aw dɛn kin du dis Keratometry tɛst?
Dis na tɛst we kin rili kwik ɛn we nɔ kin mek pɔsin fil pen. Yu kin du am we yu de du yu ay ɛgzam ɔltɛm. Yu nɔ nid fɔ sɛt wan sɛpret de fɔ am.
Dɛn kin yuz wan tin we dɛn kɔl ‘Keratometer’ fɔ dis. We yu luk am fɔs, i tan lɛk smɔl tɛliskɔp. Bɔt, i nɔ de luk di sta dɛn we de fa, bɔt i de luk yu yay dɛn we rili nia. Lɛ wi tek wan step-by-step luk pan aw dɛn de du di tɛst.
| Step dɛn we yu fɔ du | Wetin de apin? |
|---|---|
| 1. Fɔ pripia yusɛf | Dɛn go aks yu fɔ sidɔm na chia, put yu chin na spɛshal ples na di mashin, ɛn put yu fɔɛd pan spɛshal ba. Dis na fɔ mek yu ed de na wan ples we yu de du di tɛst. Dɔn di dɔktɔ go ajɔst di mashin so dat yu yay go de na di rayt say. |
| 2. Fɔ si tru di divays | Dɛn go aks yu fɔ luk tru wan smɔl ol na di mashin (di aypis). I tan lɛk se yu de luk tru baynuk. Yu kin want fɔ lɔk di ɔda yay bak we dɛn nɔ de chɛk dis tɛm. |
| 3. Fɔ luk di pikchɔ we de insay | Insay di mashin, yu go si wan pikchɔ we tan lɛk tri sɛklɔ, ɔ wan pikchɔ we gɛt pɔsitiv (+) ɛn nɛgitiv (-) sayn dɛn. Dɛn advays yu fɔ luk am wit yu yay ɛn nɔ blink yu yay. |
| 4. Fɔ rikodɔ di mɛzhɔmɛnt dɛn | As yu de luk da pikchɔ de, di dɔktɔ de tɔn di nɔb dɛn na di mashin fɔ mek dɛn pikchɔ dɛn de. Wan tɛm, dɛn tu sayn dɛn de we gɛt plɛnti plɛnti (+) kin tɔch dɛnsɛf. Na da rayt tɛm de, i kin rayt di mɛzhɔmɛnt dɛn. |
| 5. Fɔ chɛk di ɔda yay | We dɛn dɔn dɔn wan yay, dɛn kin tɛst di ɔda yay di sem we. Di wan ol tɛst kin tek fɔ shɔt tɛm, lɛk sɔm minit so. |
Ɛni risk ɔ bad tin de fɔ dis tɛst?
Nɔto so i bi atɔl. Dis na 100% sef tɛst . I nɔ de mek yu gɛt ɛni risk ɔ pen . Pan ɔl we di layt we de kɔmɔt na di mashin brayt smɔl, i nɔ go ambɔg yu yay ɔ yu yay.
Bɔt wan smɔl tin de. Bifo yu kɔl dis "disadvantage," tink bɔt am as fɔ no di kayn we aw dis tɛst tan. Kεratometri tεst nכto 100% akכrd mכsu fכ yu kכnia, bכt na rili gud εstimat.
A go ɛksplen wetin mek simpul wan. Tink bɔt wan glob. I fayn fayn wan rawnd ɛn i smol. Bɔt wi no se wi Wɔl nɔ rili smol so, ay ay mawnten dɛn de lɛk di Himalayas, dip si dɛn lɛk di Mariana Trench, ɛn bɔku ɔda tin dɛn lɛk vali dɛn. Ɛn di Wɔl nɔto pafɛkt sfɛra sɛf. Bɔt wan glob na big ɛp fɔ ɔndastand usay Sri Lanka de ɛn usay Amɛrika de, nɔto so?
Di keratometry test na di sem tin. I de mɛzhɔ di shep we wi kɔnia gɛt, ɛn i de tek am se na pafɛkt sfɛra. Fɔ tru, wi yay nɔto pafɛkt sfɛra dɛn, ɛn natin nɔ de we kin mek wi yay dɛn difrɛn. Bɔt na wan tin we rili yusful ɛn valyu fɔ no kwik ɛn fayn fayn wan if yu gɛt astigmatism.
Naw, sɔm dɔktɔ dɛn we de mɛn di yay kin yuz mɔ advans tɛst dɛn bak, lɛk fɔ mek di kɔnia map, we kin mek dɛn ebul fɔ mɛzhɔ mɔ kɔrɛkt wan.
Wetin na dɛn keratometry ridin ya (K ridin)?
di rizulεt dεm fכ dis tεst dεn kכl dεm ‘K ridin dεm’ . Di yunit we dɛn de mɛzhɔ fɔ dɛn tin ya na in dɛn kɔl diɔpta .
Nɔ fred fɔ dɛn nɔmba ɛn di ditel dɛn ya. Dɛn tin ya na fɔ mek yu dɔktɔ ɔndastand. I go luk dɛn rizɔlt ya ɛn no di rayt tin we mek yu si chenj.
| Di kɔndishɔn na di yay | Di kayn we aw K ridin de |
|---|---|
| Wan kɔnia we gɛt wɛlbɔdi ɛn rawnd (Nɔmal Kɔnia) . | di כl kכnia gεt di sem, kכnstant K valyu. Dis valyu kin de arawnd 43 diopta. |
| Wan yay we gɛt astigmatism | Yu go si tu K valyu dɛn. Wan fɔ di pat we stip pas ɔl na di kɔv, ɛn di ɔda wan fɔ di pat we flat pas ɔl. di difrεns bitwin dεn tu valyu ya de sho yu lεvεl fכ astigmatism. |
Dis K ridin go gayd yu dɔktɔ fɔ pik di rayt glas, kɔntakt lens, ɔ, if nid de, di rayt lens fɔ ɔpreshɔn.
Ustɛm a fɔ go to mi dɔktɔ?
Yu dɔktɔ go tɛl yu aw ɔltɛm yu fɔ chɛk yu yay. I impɔtant fɔ fala da schedule de.
di shep fכ wi yay kin chenj nכmal wan as tεm de go, so di lεvεl fכ astigmatism kin chenj. Bɔt if yu notis wan chenj we de apin wantɛm wantɛm na yu yay, mɔ if i nɔ klia pas aw yu kin si am, nɔ ignore am. E kin bi sayn fɔ wan sik lɛk keratoconus wae nid fɔ trit kwik kwik wan. So if yu notis se yu de si sɔntin we rili chenj wantɛm wantɛm, go to yu dɔktɔ wantɛm wantɛm.
Mɛmba se dis nɔto tɛst we yu go ebul fɔ pas ɔ we yu nɔ ebul fɔ pas. Na jɔs tɛst fɔ si aw yu yay de du fayn. I nɔ mata aw yu astigmatism bad, yu kin stil si klia wan wit di rayt glas, kɔntakt lens, ɔ ɔda tritmɛnt.
Mɛsej we dɛn kin kɛr go na os
- Keratometry na simpul, nɔ gɛt pen, ɛn sef tɛst fɔ no aw yu kɔnia kɔba.
- Dis kin mεnli no di kכmכn vishכn we dεn kכl astigmatism.
- Di rizɔlt fɔ di tɛst (K ridin) go ɛp yu dɔktɔ fɔ pik di bɛst glas, kɔntakt lens, ɔ lens we yu go yuz afta yu dɔn ɔpreshɔn.
- If yu si chenj wantɛm wantɛm ɔ big chenj na yu yay, nɔ ignore am ɛn go to ay dɔktɔ wantɛm wantɛm.
