Kuvhiyiwa kwecataract ndiko kuvhiya kwakanyanya kunoitwa pasi rose uye muFrance, nekuvhiya kunoda kusvika mazana manomwe gore rega rega. Iyo inokurumidza uye yakaderera-njodzi oparesheni inodzoreredza kuona nekuisa yakagadzirwa kudyara muziso.

Kuvhiyiwa kweCataract kuvhiyiwa kubvisa lenzi kubva muziso rinobatwa nechirwere uye, kazhinji, kuchitsiva nelenzi rekugadzira.

Kazhinji, lens (lens yeziso) yakajeka uye yakajeka. Iyi lenzi nokudaro inobvumira kupfuura kwechiedza kuenda kune retina, iyo inoshanda sechidzitiro uye inobvumira kuona. Kana cataract ikakura, lenzi inova isina kujeka uye izvi zvinokanganisa kuona. Chirwere chakajairika chinobata vanopfuura mumwe muvashanu kubva pazera re65 uye vangangoita vaviri muvatatu mushure memakore makumi masere nemashanu.

Kana chirwere chacho chakanyanyisa uye chichiita kuti hupenyu hwezuva nezuva uye mabasa emazuva ose akaoma, chiremba angaratidza kuvhiyiwa. Kuvhiyiwa kwecataract ndiyo nzira chete yekudzoreredza kuona kana chirwere chatanga.

Kuvhiyiwa kwecataract kunoitwa neophthalmologist. Iyo inokurumidza nzira iyo inowanzotora 15 kumaminitsi e30 pasi peanesthesia yemunharaunda, izvo zvinoreva kuti murwere akasvinura panguva yekuita.

Panguva yekuvhiyiwa, chiremba anovhiya achaita diki diki (incision) muziso kuitira kuti lens yakabatwa ibviswe. Kana aibvisa, anoisa lenzi diki yepurasitiki inonzi intraocular implant.

Kana maziso ese ari maviri akabatwa, maoparesheni maviri akaparadzana anozodikanwa uye achaitwa mavhiki mashoma akaparadzana. Izvi zvinoita kuti zvikwanise kudzoreredza kuona kwakajairika muziso rekutanga rakavhiyiwa pamberi pekuvhiya kwechipiri.

Mune zvimwe zviitiko, chiremba angakurudzira kuvhiyiwa kwelaser. Iyi ndiyo nyaya, semuenzaniso, kana ichitsvaga kugadzirisa astigmatism panguva imwe chete nekubvisa cataract. Muchiitiko ichi, kuvharwa kwebhegi rine lens kunogadzirwa nelaser.

Kazhinji, kuvhiyiwa kwecataract inzira yekunze. Kureva kuti murwere anogona kuenda kumba masikati. Zvisinei, zviri nani kuronga kuti munhu anenge achiperekedza ange aripo nekuti ziso rakavhiyiwa rinenge rakavharwa nebhandeji uye izvi zvinogona kukanganisa kuona kwese zvichienderana nemamiriro erimwe ziso. Muzviitiko zvakawanda, kuvhiyiwa kunobvumira zvakanakisa kuona kudzoreredza zuva mushure mekuvhiyiwa kana mukati memazuva mashoma. Murwere anobva atangazve hupenyu hwake hwemazuva ese.

Mushure mekuvhiyiwa, lenzi yekugadzira inova chikamu cheziso uye haidi kurapwa kwakawedzerwa kana kutarisirwa kwakakosha. Nekudaro, zvinogoneka kuti iwe uchasangana nekusagadzikana kweziso mushure mekuita uye emuno anti-kuzvimba kurapwa kuchadiwa kwemavhiki mashoma.

Zvinetso pashure pokuvhiyiwa hazviwanzoitiki. Kana ukanzwa kurwadziwa kwakanyanya kana kuderera kwekuona mumazuva nemavhiki anotevera, unofanira kuonana nachiremba wako kana kuenda kuchipatara.

Ngozi yematambudziko yakakura kana paine chimwe chirwere cheziso kana chirwere chakakomba chakabatana, senge glaucoma kana macular degeneration. Muchiitiko ichi, kuvhiyiwa kwecataract kunogona kusavandudza maonero.
