Chaizvo nemhaka iyi kunobatsira iwe kugadzirisa astigmatism panguva LEVEL zvichienzaniswa idenderedzwa kwakajairika Manyiminya zviridzwa uye magirazi.

Kune dzakaoma uye akapfava toric lenses. Sendinokuyeukai kwavari kunobva chaiyo iri mhando. Soft lenses vari vasununguka ari selection, kushandiswa uye hanya, saka vanhu vakawanda vanosarudza kwavari. Pasinei neizvi, vanachandagwinyira Manyiminya zvigadzirwa kugadzira michina mumakore achangodarika yachinja, ine pesvedzero inobatsira pamaitiro avo kunyaradzwa pamwero. Mukuwedzera, vane kwenguva refu basa, uye anonyatsorayiridzwa wakanyatsokodzera kuti rakasungwa astigmatism, nokuda kwayo mukurumari uye dzigadziridzwe Maumbirwe cornea. Kusarudza zvinoenderana zvatinoda, kwokuomerwa chiratidzo nematambudziko, uyewo vanhu vanowanzosarudza.

Features

Munguva ichangopfuura, toric kuonana izvo kugadzira michina yachinja. It kunoratidzwa kwete chete zvinhu, maitiro uye kutarisirwa kururamiswa pamwero, uye magadzirirwo. To musi, specialized makambani kupa ruvara toric lenses, izvo, kuwedzera ayo Manyiminya basa, vanewo zvizorwa nomugumisiro.

Toric lenses dzinoitwa kubva hydrogel uye silicone hydrogel, kana totaura zvinyoronyoro mhando, kana kubva gasi permeable zvinhu kwakavakirwa silicone kana totaura zvakaoma shanduro. Special nzeve akafanirwa chakafanana Manyiminya chiridzwa. Kana chinyakare embodiments kazhinji idenderedzwa, kuti vane dzinonzi toric sferotsentricheskuyu magadzirirwo runovabvumira zvakanyatsorurama yakarurama astigmatism. Nemhaka iyi zvakafanana musimboti ane panguva mbiri masimba Manyiminya, kuti ndicho chikuru zvinobatsira ainakidzwa toric izvo. How kupfeka zvokusarudza siyana, uudze mazvikokota.

Musiyano pakati idenderedzwa uye toric lenses

Idenderedzwa uye toric lenses - chii uye chii musiyano? achifananidzira yokutanga basa kururamisa myopia kana hyperopia, zvino sezvo wechipiri, nokuda chimiro chayo, panguva imwe chete kuita mbiri Manyiminya mabasa. Mumwe chakarurama rakagadzirirwa kugadzirisa astigmatism pane vamwe Meridian, apo mumwe anotonga kutarisana acuity.

Toric lenses nokuti astigmatism anofanira kutora rimwe chinzvimbo. meridians dzavo vanofanira mukanyatsoteerera dzinoenderana nzvimbo namasanhu ari kuremara wezvakaonekwa. Chete iyi, vacharamba kuita mabasa avo ose. Idenderedzwa kuonana gogorosi ane yakatsiga refractive simba pamusoro wayo pepasi, saka hazvina basa kuti pane chii nzvimbo pamusoro cornea zviri.

zvakwakanakira

Toric lenses vane zvakawanda zvinobatsira kana tichienzanisa nemakwenzi wezvakaonekwa kururamiswa.

• Nokuda chimiro chayo, ivo panguva kuita mabasa maviri: akarurama chiratidzo uye kubvisa kuremara astigmatism.
• Anopa mukana Zvakanyanya Kunaka Panguva Yepamuviri nzvimbo pamusoro cornea nokuda muchimiro uye mamwe "namano."
• dzakasiyana kwakadaro akakodzera vaya vanotambura kwete chete kubva astigmatism, asiwo vamwe corneal kurwara.
• lenses kwakadaro kunogona kuita basa izvo weziso iri chiitiko yave ichiitwa kuvhiyiwa kubvisa cataract. Nokuti chinangwa ichi, pakaitwa toric intraocular izvo.

Kana kushandiswa chiratidzo kururamiswa Manyiminya nyaya dzakaoma mhando, vane zvimwe zvazvakanakira, ramakagadzwa zvinotevera zvinofanira kucherechedzwa: wakakwirira pamwero okisijeni kuti cornea, yakarurama chiratidzo kururamiswa, kusavapo mugumisiro "ziso yakaoma" uye kuramba mapuroteni deposition. Mukurumari uye yakareba kushandiswa - zvinokoshawo zvakanakira kuti vanachandagwinyira toric lenses. Mutengo mikana yakadaro zvishoma kupfuura munyoro, uye kazhinji anoda kubatsira kubva 300 kusvika 3000 rubles.

kutadza

Toric lenses vane zvazvakashatira sezvo kwakajairika vanachandagwinyira nyoro kana mhando. Panyaya wokutanga mhando Manyiminya mano, zviri pakutanga:

• nguva pfupi kushandiswa;
• kudziviswa kuwana reokisijeni kuti cornea, iyo nyoro izvo nokuti anenge chose anofukidza;
• Inosimudzira ziso yakaoma, izvo dzimwe nguva zvinoda kushandiswa anokosha Madonhwe kana gel;
• nzvimbo pamusoro izvo mapuroteni deposits kubva ziso, izvo zvingaita kuti munhu sema maitiro uye nevamwe.

Panyaya vanachandagwinyira zviridzwa, zvinotevera payakaipira ndiwo:

• zvakaoma zvikuru uye dzakareba pakusarudza toric lenses;
• Low pamwero nyaradzo uye kudiwa kuchinja cornea.

Zvakakosha kuziva imwe yakawanda nguva. Pasinei mhando mutengo - imwe drawback, vane toric lenses. Mutengo mikana yakadaro yakakwirira zvikuru, pasinei nokuti vari nyoro kana dzakaoma. Izvi imhaka yokuti vari vaviri kutambura nezvinetso nearsightedness kana Kuona zviri mberi, uye astigmatism urema panobviswa.

How kusarudza?

Pakusarudza toric lenses kunofanira kuitwa ane ruzivo ophthalmologist, nekuti zvakakodzera kufunga masimba maviri Manyiminya. Zvinokoshawo kuziva mhando - rakaoma nyoro kana. Tsanangudzo yokutanga ndiyo iri vasununguka, asi wechipiri ane zvimwe zvinhu. Kana munhu anoda izvozvo pfungwa zvakaoma, zvakakosha kuyeuka kuti chigadzirwa iri kugadziridzwa kuti cornea, saka pashure nechirwere zvakafanira kumirira kusvikira vanachandagwinyira izvo vachaitwa nomumwe.

Kuwedzera kwaro Manyiminya kushanda, dzomutauro vakadaro vanewo decoration nomugumisiro. Zvinangwa izvi, unogona kushandisa chitsvuku toric lenses. Havazosimudzirani chete zvakaratidzwa echokwadi, asi zvishoma kuchinja chitarisiko chavo.

nokukiya zvigadziriswe

Kusiyana idenderedzwa, toric izvo achaita zvinobudirira zvikuru chete kana zvakarurama papi. Pakadaro ari cylindrical zvinoriumba achaita chinangwa panguva optimum aspherical cornea wongoramba.

• Prismatic kutsigisa igwa. Kuvapo kuzvimba duku yepazasi nzvimbo izvo. Vakadhakwa regiravhiti Manyiminya mudziyo achipinda yakarurama nzvimbo.
• Periballast. Panyaya iyi, kuti izvo ine denser nharaunda pamusoro uye pasi, izvo dziri pasi namafungiro. Izvi zvinobvumira kuti irambe panzvimbo.
• Rakanga. Nokuti chinangwa ichi pasi izvo rwagurwa nechimwe chikamu, uye pamwe ichi zvidimure wanamatira mu yepazasi chikamu remakore.

Kuti tiwane yakarurama zvikuru Kuda kutamba panguva vagadziri vakawanda vanoshandisa vanoverengeka nzira idzi.
