Interventions
phacoemulsification combined with IOL and CTR implantation
Device: CTR (276001G； OPHTEC BV, Netherlands) Device: IOL (920H; Rayner Intracular Lenses Limited，Hove，East Sussex，UK) All patients undergo uneventful phacoemulsification by a 3.0 mm temporal transparent corneal incision using Centurion Vision System (Alcon Laboratories, Fort Worth, TX, USA). After the nucleus and cortex are removed, a capsular tension ring is implanted in the capsular bag and then IOL is implanted.
