Brief 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.
Eligibility Criteria
Inclusion Criteria: * Age ≥ 18 years. * Clinical diagnosis of retinitis pigmentosa (RP). * Bilateral cataract meeting the indications for IOL implantation. * Willingness to participate in the study and provision of signed informed consent. Exclusion Criteria: * History of intraocular surgery. * Severe zonular weakness (e.g., zonular dialysis \>90°, lens subluxation/dislocation) * Other ocular comorbidity: such as pseudoexfoliation syndrome, ocular trauma, corneal dystrophies, uveitis, etc. * Severe systemic diseases: such as severe hypertension, diabetes, heart disease, Alzheimer's, Parkinson, etc.
