Hyperopic astigmatism. Laser chiono kururamiswa

Haasi wose anozvikudza kuti ane chiratidzo chakanaka. Kazhinji kacho pane abnormality. Somuenzaniso, kungava hypermetropic astigmatism, inova yakatsauka pana hyperopia.

Muzvimwe zviitiko zvinogona kuitika zvachose asymptomatic, asiwo zvinoitika kuti zvokurwara kunokonzera nomusoro uye kwakawedzera kugumbuka. Izvi mhando astigmatism zvikuru kusingawanikwi meso ose, kazhinji bata chete chete. Ngatiedzei kunzwisisa zvinokonzera chirwere chacho kurapwa.

zvikonzero

The cornea uye izvo ziso kwomuzvarirwo chiono vari idenderedzwa mu chimiro. Refracted danda chiedza pamusoro the retina ndee panzvimbo imwe. Asi kana ziso pamwe astigmatism, danda muchiitiko ichi, uye kuumba mbiri pfungwa pane chimwe. Somugumisiro, chiono kaviri zvinova blurry uye kunaka.

Saka, hyperopic astigmatism kunoitika nokuda kwezvikonzero zviviri:

• gogorosi deformation;
• kuchinja pezvakaita cornea.

Panguva ino hazvina zvakazara yakasimbiswa nokuti chii chiri kuitika. Masayendisiti zvinoratidza kuti deformation of izvo - iri vachiberekwa anomaly okukura uye kwoupenyu zvinonzi kuumbwa chaizvo kashoma. Uyewo Maumbirwe cornea dzinosiyana nokuda scarring Somuenzaniso pashure kukuvara kana kuvhiyiwa.

Kakawanda ine zvishoma mwero hyperopia kusvika 0.5 diopters. Hazvina kufungwa kutyorwa, hapana kusagadzikana, munhu asingadi kunzwa zvakanaka uye haina chokuita unhu wezvakaonekwa.

zvokurwara mhando

• Simple astigmatism - iyi nyaya imwe Meridian ane kuipa ziso kuona, uye mumwe kunoitika hyperopia.
• Astigmatism - mune zvose meridians ziso kunoitika Kuona zviri mberi, kuti, ainyanya kukoshesa pfungwa dziri seri the retina.

Uye nesimba-hyperopic astigmatism, uye mano simukai kubva ndechokuti cornea ane asiri idenderedzwa chimiro. Zvikuru kashoma Chinokonzera zvemamiriro curvature pamusoro izvo.

Uyewo, iyo astigmatism zvinogona zvakananga kana Ivan Kuchin mhando. Hwaro weboka iri nyaya iri inobva refractive simba iri huru meridians. Kana zviri kwasimbiswa hunyambiri Meridian iri yakarurama mhando. Asi kana wakasimba refraction kunoitika yakatambarara, izvozvo hyperopic astigmatism harungashandurwi mhando.

zviratidzo

Izvi kutadza kuona zvakanaka kungazviratidza nenzira dzakasiyana, uye kunoenderana mwero kwayo zvakaoma.

Kana hyperopic astigmatism ari munyoro, zviratidzo zviri anenge imperceptible. Murume haadi kuteerera chokwadi kuti chiratidzo chake anotanga kudzikira. Kakawanda, munhu munyoro mwero zvokurwara padzakacherechedza panguva dzose inspections.

Avhareji mwero astigmatism kunoratidzwa sezvinotevera: pane madzerere, icho pamwe chete kaviri chiratidzo, kutemwa kana dzungu. Munhu haagoni kunyanya basa chokuita eyestrain. Panguva iyoyo uye vanhu vanomanikidzwa kwachiremba.

Zvakakomba astigmatism kunoratidzwa kwazvo zviratidzo. Kakawanda hunotanga zvikuru achiona kaviri, uye madzerere hunowedzera raidudzwa. Pane kurwadziwa mumaziso, kutemwa nomusoro, uye dzimwe nguva nokushatiriswa svoto. Panguva yokuongorora, chiremba anoti simba kwakakura kutarisana acuity.

Hyperopic astigmatism kurapwa

zvokurwara Izvi kurapwa nenzira mbiri:

• kuchinja;
• operative.

Kana kuduku mwero hyperopia, uye pasina concomitant zvirwere (asthenopia, strabismus) kurapwa haigoni kuitwa kubva muna iyi unhu zvaakaratidzwa asiri kuipa. Panoongororwa zvirwere izvi kururamisa fanira. It iri ndechokuti munhu akagadzwa chaiwo magirazi pamwe lenses fillister. Kudzipfeka kuva zvachose kana chete chokupika chero basa. muripo kunosanganisirawo kwokupfeka kubatana lenses.

Asi zvinofanira kutaurwa kuti astigmatism havagoni kurapwa chero lenses kana magirazi. Vanobatsira chete kuti adzokorore nayo kuti kubvisa kunetseka chokuita kutadza kuona zvakanaka. Astigmatism ikarapwa surgically, uye zvikurukuru iri Laser chiratidzo kururamiswa.

The nzira kushanda pakurapwa

Modern ophthalmology anobvisa astigmatism pamwe pakuvhiya.

• Laser thermokeratoplasty. Izvi mhando kutsiurwa kuti mune peripheral mapazi ari cornea pane dzimwe pfungwa yacho Laser akashandisa pachivara kutsva. Izvi zvinobatsira kuti kuderera kwemitambo collagen fibers, zvokuti cornea inoshanduka chimiro. In arikunze, zvinova zvikuru sandara, uye pakati - a convex, zvichiguma nani zvaakaratidzwa.
• Termokeratokoagulyatsiya. Voitakura kunze saizvozvo sezvo Laser thermokeratoplasty chete kutsva apo aishanda aine tsono tembiricha yakakwirira.
• Hyperopic Laser mu-situ keratomileusis. Pari, nzira iyi yokurapa ichaongororwa kwazvo yakachengeteka uye inobudirira zvikuru. Laser chiratidzo ichi kururamiswa kunobatsira kubvisa astigmatism, mwero uye yakanyanya siyana. It rinoitwa sezvinotevera: mune chapamusoro pamusoro cornea unotemwa uye duku piece jira inodedera parutivi. Kuburikidza incision ichi isu tisvike pakati akaturikidzana ari cornea panguva yayo arikunze. Achibatsirwa Laser Ipwa chikamu chiduku pakati layer uye kurova-rova adzorerwa panzvimbo yaro. nzira iyi anoranga pezvakaita cornea, kuchinja curvature kwayo, uye kuona anomutswa nokukurumidza.

Kana paine zvikonzero nokuramba kushandisa nzira iyi yokurapa, rinoitwa kwacho sezvo nokubviswa izvo, ivo muchibereko phakic intraocular lenses, keratoplasty.

Hyperopic astigmatism muvana

Izvi vanotaura ziso muvana pasi gore rimwe anonzi romuzvarirwo (vasiri) chinonakidza. Asi vana vakura, zvokurwara ichi kunooneka pacharo saizvozvo sezvo nedzevakuru. Zvichemo mwana uyu nyaya hadzinzwisisiki: kutekenyedzwa ichipfuta mumaziso, kurukutika, kutemwa nomusoro, kusada kuzochera, kuverenga nokunyora.

Kazhinji hosha iri vachiberekwa zvakasikwa uye wabva mubereki mwana. Naizvozvo, kana mhuri ine munhu achitambura astigmatism, iva nechokwadi kuratidza mwana wenyu ophthalmologist nokukurumidza sezvingabvira. Kana kukurumidza kurapwa pashure pechinguva mwana anogona kuva squint.

Nokururamiswa zvokurwara muvana

Kana hyperopic astigmatism ari munyoro, hakufaniri kuva kururamiswa chaiyo. Kakawanda, mwana ari kupfeka chiremba nyaya ndinonongera anokosha muviri ziso.

Kana chirwere zvakawanda raidudzwa, chiremba otora shoma dzinokosha magirazi murefu kana lenses. Pfungwa vanofanira kusarudza chiremba chete ane ruzivo, lenses dzavo vanofanira kuva zvakasiyana mwero refraction, saka, zvinoitwa nomumwe.

Hyperopic astigmatism muvana zvinogona kudziviswa sezvo mangwanani sezvinobvira kuvadzidzisa kuti zvakanaka kuparadzira mutoro pamusoro ziso.

mhedziso

Hyperopic astigmatism - chakakomba chirwere ziso kuti inogona kurapika expeditious nzira chete. To hosha haina mberi nyanzvi prescribes kwokupfeka anokosha magirazi kana kuonana lenses, saka zvakakosha kuti muone chiremba nguva.
