Cataract ndiko kudzikamisa ziso reziso.

Iyo lens yeziso inowanzo kujeka. Inoita kunge lens pane kamera, inotarisa mwenje sezvo ichipfuura kumashure kweziso.

Kusvikira munhu ave neanosvika makore makumi mana neshanu, chimiro che lens chinokwanisa kuchinja. Izvi zvinobvumira lens kuti itarise pachinhu, kunyangwe chiri padyo kana kure.

Sezvo munhu anokwegura, mapuroteni ari mu lens anotanga kuputsa. Nekuda kweizvozvo, lens inova nemakore. Izvo izvo ziso rinoona zvinogona kuoneka zvisina kujeka. Aya mamiriro anozivikanwa sekati.

Zvinhu zvinogona kumhanyisa cataract kuumbwa ndeizvi:

• Chirwere cheshuga
• Kuvhiringidza kwemaziso
• Kukuvara kweziso
• Nhoroondo yemhuri yemakona
• Kushandiswa kwenguva refu kwecorticosteroids (inotorwa nemuromo) kana mimwewo mishonga
• Radiation kuratidzwa
• Kusvuta
• Kuvhiya kweimwe dambudziko remaziso
• Kunyanya kuratidzwa kune ultraviolet mwenje (zuva rezuva)

Makaraketi anokura zvishoma nezvishoma uye asingarwadze. Kuona muziso rakabatwa zvishoma nezvishoma kunowedzera.

• Kudzikama kwakapfava kweiyo lens kunowanzoitika mushure memakore makumi matanhatu. Asi zvinogona kusakonzera chero matambudziko ekuona.
• Pakazosvika makore makumi manomwe neshanu, vanhu vazhinji vane cataract iyo inokanganisa kuona kwavo.

Zvinetso nekuona zvinogona kusanganisira:

• Kuva nehanya nekupenya
• Makore, fuzzy, foggy, kana mafirimu maonero
• Zvakaoma kuona usiku kana kupenya kwechiedza
• Kuona kaviri
• Kurasikirwa kwemavara akasimba
• Matambudziko ekuona maumbirwo akatarisana neshure kana mutsauko pakati pemumvuri wemavara
• Kuona halos dzakakomberedza mwenje
• Kakawanda shanduko mumirau yegirazi yemaziso

Makarokiti anotungamira kudzikira kwemaonero, kunyangwe masikati machena. Vazhinji vanhu vane cataract vane shanduko dzakafanana mumaziso ese, kunyangwe rimwe ziso rinogona kunge rakaipa kupfuura rimwe. Kazhinji pane kungoita zvinyoro nyowani shanduko.

Chiyero chemuedzo weziso uye kucheka-mwenje kuongororwa kunoshandiswa kuongorora kupenga. Mimwe miedzo haiwanzo kudikanwa, kunze kwekutonga zvimwe zvikonzero zvekutadza kuona.

Kune yekutanga cataract, chiremba weziso (ophthalmologist) anogona kukurudzira zvinotevera:

• Chinja mugirazi yemaziso
• Kuvhenekera zvirinani
• Magnifying lenzi
• Magirazi ezuva

Sezvo chiono chinoramba chichiwedzera, ungangoda kuita shanduko kutenderera imba kuti udzivise kuwira nekukuvara.

Mushonga chete wekati kuvhiya kuti ubviswe. Kana cataract isiri kukuomesera kuti iwe uone, kuvhiyiwa hakuwanzo kudikanwa. Kurwara kazhinji hakukuvadzi ziso, saka unogona kuvhiyiwa kana iwe nachiremba weziso ukaona zvakakunakira. Kuvhiya kunowanzo kurudzirwa kana iwe usingakwanise kuita zvakajairika zviitiko sekutyaira, kuverenga, kana kutarisa pamakomputa kana vhidhiyo skrini, kunyangwe nemagirazi.

Vamwe vanhu vanogona kunge vaine mamwe matambudziko eziso, senge chirwere cheshuga retinopathy, icho chisingakwanise kurapwa usati watanga kuvhiyiwa chirwere chekatsi

Chiratidzo hachikwanisi kuvandudzika kusvika 20/20 mushure mekuvhiyiwa kwekatsi kana zvimwe zvirwere zvemaziso, senge macular degeneration, zviripo. Chiremba weziso anogona kazhinji kuona izvi pamberi.

Kuongororwa kwekutanga uye kurapwa kwakakodzera nguva kwakakosha kudzivirira matambudziko ekuona zvachose.

Kunyangwe isingawanzoitika, chirwere chinopfuurira kuenda padanho repamberi (chinonzi hypermature cataract) chinogona kutanga kubuda mune mamwe mativi eziso. Izvi zvinogona kukonzera chimiro chinorwadza che glaucoma uye kuzvimba mukati meziso.

Shevedza musangano kuti uone neziso rako rekuchengetedza maziso kana uine:

• Kupera kwemaonero ehusiku
• Matambudziko nekupenya
• Chiratidzo kurasikirwa

Kudzivirira kwakanyanya kunosanganisira kudzora zvirwere zvinowedzera njodzi yekubatwa nemeso. Kudzivisa kuratidzwa kune izvo zvinhu zvinokurudzira cataract kuumbwa zvinogona zvakare kubatsira. Semuenzaniso, kana iwe uchisvuta, ino ndiyo nguva yekurega. Zvakare, kana uri panze, pfeka magirazi ezuva kudzivirira meso ako kubva kumwaranzi yeUV inokuvadza.
