Nubwo umubare wa hydrogel uhuza lens urenze, burigihe ntiwashimishije mubijyanye na ogisijeni.Kuva kuri hydrogel kugeza kuri hydrogel ya silicone, dushobora kuvuga ko gusimbuka kuzuye byagezweho.None, nkijisho ryiza ryo guhura kurubu, niki cyiza kuri hydrogel ya silicone?
Hydrogel ya Silicone ni hydrophilique organic polymer yibikoresho bifite ogisijeni nyinshi.Urebye ku buzima bw'amaso, ikibazo cy'ingenzi intumbero yo guhuza igomba gukemura ni ugutezimbere umwuka wa ogisijeni.Inzira ya hydrogel isanzwe ihuza amazi ashingiye kumurongo nkuwitwara kugirango ogisijeni igere muri cornea, ariko ubushobozi bwo gutwara amazi ni buke cyane kandi bugahumuka byoroshye.Ariko, kwiyongera kwa silicon bigira itandukaniro rinini.Silomone monomersufite imiterere idahwitse nimbaraga nke za intermolecular, kandi gukomera kwa ogisijeni muribwo ni hejuru cyane, bigatuma ogisijeni yinjira muri hydrogène ya silicone yikubye inshuro eshanu kurenza izisanzwe.
Ikibazo cyuko umwuka wa ogisijeni ugomba guterwa nibirimo amazi byakemutse,nibindi byiza byazanywe.
Niba amazi yibigize lens yiyongereye, uko igihe cyo kwambara cyiyongera, amazi arahinduka kandi akuzuzwa amarira, bigatuma amaso yombi yumishwa.
Nyamara, hydrogel ya silicone ifite amazi meza, kandi amazi akomeza kuba meza na nyuma yo kwambara, ntabwo rero byoroshye kubyara akuma, kandi lens iroroshye kandi yoroshye mugihe yemerera cornea guhumeka neza.
Nkigisubizo
lens ya contact ikozwe muri hydrogel ya silicone ihora ihumeka kandi ihumeka, itezimbere ihumure kandi igabanye kwangirika kwamaso, ibyiza bidahuye ninzira zisanzwe.Nubwo hydrogel ya silicone ishobora gukoreshwa gusa mugukora insimburangingo ngufi kandi ntishobora gukoreshwa kumwaka na kimwe cya kabiri cyumwaka, biracyari byiza guhitamo ibicuruzwa byose.
