Kana uine astigmatism , unogona kuve nekuvhiyiwa kweziso reLASIK . LASIK chiratidzo chekuvhiya kwekushandura chinoshandiswa kugadzirisa zvikanganiso zvekufuratira zvakadai seastigmatism, myopia , uye hyperopia . Kana uine astigmatism, chiratidzo chako chinogona kunge chichifuratira ari kure uye pedyo. Unogona kunzwa wakaneta mushure mokuverenga nekuwana kuti tsamba nemashoko zvinoita sezviri kuiswa.
Vanhu vazhinji vane astigmatism vakawana kurairwa kwemaziso kweLASIK kuti ive nzira yakachengeteka uye inobudirira yekururamisa maonero.
Nokuda kwechimwe chikonzero, kune "kushorwa" pamusoro peastigmatism kana zvichiuya kuLASIK. Zvisinei, vazhinji varwere vane astigmatism vanogona kuita chirwere chemalasi refractive. Zvose izvi zvinokonzerwa neicho ndicho chaiva chokutanga chekuona dambudziko rakagamuchirwa neDFA yeLASIK.
Chii chinonzi Astigmatism?
Astigmatism inowanzosanzwisiswa. Vanhu vane astigmatism, kwete astigmatism. Icho chinetso chekuona kazhinji chinokonzerwa ne cornea, yakajeka dome-seyakagadzikana sarudzo pamucheto wekutanga weziso, ine chimiro chakafanana nebhola, panzvimbo yebhaketi. Saka, pane simba rakawanda kana kupfuura kuputika mune imwe meridian, somuenzaniso pa 90 degrees, kupfuura pane kune imwe meridian pa 180 degrees. Nepo huwandu hweastigmatism inowanzonyanya kuratidza astigmatism, munhu anogonawo kuva nerantialular astigmatism.
Iyo cornea inogona kunge yakazara zvakakwana kana yakakomba, asi lens mukati meziso rine simba rinotyisa.
Maitiro Astigmatism Anoenzaniswa
Astigmatism inotaridzwa neine corneal topographer. A corneal topographer mhizha inogadzirisa dhoni rezviedza pa cornea. Dhiyabhorosi iyo inofungidzira kumashure inoratidza kuvhara pamusoro pese cornea inoshandiswa kuverenga chiyero uye kutungamirirwa kweastigmatism.
Kuwanda kwesimba rinodikanwa kugadzirisa astigmatism inotaridzwa nephoropter, chiridzwa chinoshandiswa apo chiremba anobvunza, "Ndeipi iri nani, imwe kana maviri?" Vanachiremba vanoshandisawo aberrometer pamberi pekuona kuti astigmatism inobata hutano hwekuona kwako.
Dzimwe Nzira Dzokugadzirisa Astigmatism
Kunyange zvazvo vanhu vazhinji vane astigmatism vanogona kuva neLASIK, vamwe vanhu vane astigmatism yakawandisa kuti laser iruramise. Zvisinei, dzimwe nguva, vanhu vanogona kuva nedzimwe nzira dzinonzi astigmatic keratectomy (AK) kugadzirisa chero astigmatism yakasara. Kematera inoshandiswa inoshandisa nzira yakakurumbira muma1980 inonzi RK, kana radial keratectomy. Mune chirongwa cheAA, chiremba anovhiya anyanzvi anoita zvishoma pane dzimwe nzvimbo dzinokosha mu cornea kuita kuti cornea iwedzere. Izvi dzimwe nguva zvinosanganiswa nemimwe nzira isina kukodzera inonzi "LRI", kana kuti chimbal inofadza kuvhara. I-LRI inogadzirwa pamakona akasiyana e-cornea iyo inokonzera kugadzikana zvishoma mupfungwa iyoyo.
Kuongorora kwekuona kwako kuchadiwa kuti uone kana iwe uri mukana weLASIK. Chimiro uye kuoma kwee-astigmatism yako zvichabatsira ophthalmologist yako kusarudza kana chirongwa cheLASIK chekuona chichakubatsira iwe.
Vamwe vanhu vane astigmatism havafaniri kuva neLASIK, sezvo dzimwe humwe unhu uye maitiro emeso avo anovadzivirira kubva pakuva nemigumisiro inobatsira.
