Summary

This is a randomized controlled trial to investigate the effect of capsular tension ring (CTR) implantation on intraocular lens (IOL) tilt and decentration in cataract patients with high myopia.

Conditions

  • Cataract
  • High Myopia

Interventions

PROCEDURE

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.
