Summary

This is a self-controlled randomized clinical trial to investigate the effect of capsular tension ring (CTR) implantation on intraocular lens (IOL) position in cataract patients with retinitis pigmentosa(RP). Each patient will receive CTR implantation in one eye, with the fellow eye serving as control. Postoperative outcomes, including visual acuity, IOL position, and postoperative complications will be compared between eyes.

Conditions

  • Cataract
  • Retinitis Pigmentosa (RP)

Interventions

PROCEDURE

CTR implantation

Device: CTR (275001G, OPHTEC BV, Netherlands) All patients undergo uneventful phacoemulsification by a 2.2 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 (J\&J Tecnis DCB00) is implanted.
