Kunengxenye esweni ebizwa nge-lens.Iyilensi ye-convex enezinhlangothi ezimbili esobala, edlala indima yokudlulisa ukukhanya nokugxila esweni.Ngaphandle kwawo, asikwazi ukubona ngokucacile.Ngokukhula kweminyaka, le crystal esobala izoba ne-turbid kancane, okuholela ekwehleni kokudluliswa kokukhanya.Uma lehla ngezinga elithile, lizophazamisa umbono wethu futhi libe amakhathakhatha.Ngesikhathi sokuhlinzwa kwe-cataract, i-lens ye-turbid ikhishwa ngamandla e-ultrasonic.Uma kuphela i-lens ye-turbid ikhishwa, inkinga yokudlulisa ukukhanya iyaxazululwa, futhi ukukhanya kungangena esweni futhi.Kodwa inkinga yokugxila isekhona, ngakho-ke sidinga ukufaka i-lens ye-intraocular ebonakalayo endaweni yokuqala ye-lens, engakwazi ukuxazulula inkinga yokudlulisa ukukhanya kuphela, kodwa futhi ukuxazulula inkinga yokugxila, ukuze sikwazi ukubona emhlabeni wangaphandle ngokucacile.Ngakho-ke, i-lens ye-intraocular kufanele ifakwe ekuhlinzweni kwe-cataract, okuwukuhlinzwa okuphelele kwe-cataract
