AIM: To evaluate the clinical results of capsular tension ring (CTR) implantation in phacoemulsification for eyes with congenital lens subluxation. METHODS: This study comprised 18 patients (31 eyes) with congenital ectopia lentis. All patients received phacoemulsification with CTR and intraocular lens (IOL) implantation. Visual acuity before and after surgery were examined. IOL decentration were measured with Image-Pro Plus image processing software. The complications were also recorded preoperatively and postoperatively. RESULTS: Uncorrected vision of all eyes increased after surgery, and all cases had different degree of IOL decentration after surgery. Two eyes received CTR scleral fixation 3mo after surgery because the IOL decentration aggravated during the follow-up period. CONCLUSION: Phacoemulsification with CTR and IOL implantation is effective and safe for congenital lens subluxation. The implantation of CTR increase the stability of the capsular bag, improve the safety of surgery, and maintain the right position of IOL. CTR scleral fixation is a effective supplement for progressive cases.
