Effect of Capsular Tension Ring Implantation on Postoperative IOL Position in Retinitis Pigmentosa Patients With Cataract: a Single-center, Randomized, Self-controlled Study
Status: Recruiting
Location: See location...
Intervention Type: Procedure
Study Type: Interventional
Study Phase: Not Applicable
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.

Target number of participants: 88
Treatments
Experimental: Treatment Group: IOL Plus CTR implantation
Patients will undergo phacoemulsification combined with IOL and CTR implantation
No_intervention: Control Group: IOL implantation Only
Patients will undergo phacoemulsification combined with IOL implantation. 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, IOL (J\&J Tecnis DCB00) is implanted in the capsular bag.
