Instead of conventional phacoemulsification, the lens nucleus underwent hydrodis-section and extracted manually; then an aspiration device was used to remove the cortex through the auxiliary incision.
Nuclear cataracts are the most common type of cataracts and involve the yellowing of the lens nucleus. Along with various mechanisms, each type of cataract has different associated risk factors [102].
