Capsular tension ring implantation for zonular abnormalities

Objective To evaluate the clinical results of phacoemulsification with capsular tension ring (CTR) and intraocular lens (IOL) implantation for cataracts with zonular abnormalities.Methods This prospective study comprised sixteen cataracts of 10 patient swith weakness or partially broken ciliary zonule.After insertion of a CTR,phacoemulsification with IOL implantation was performed.Results Postoperative follow-up were six months,two patients lost follow-up.At the last postoperative examination,best corrected visual acuity (BCVA) of the eiht patients(13 eyes)were all increased.In the-bag fixation of CTR was achieved in all eyes.IOL implanted was not centered only in one eye 6 months after surgery.Posterior capsular opacification was found in three eyes,Conclusions Phacoemulsification with CTR and IOL implantation iS effective and safe for subluxated lenses,M-CTR scleral fixation is necessarysupplernent for severely subluxated lenses and progressive cases.
