Objective To study the clinical effectiveness of capsular sac relaxing surgery(CBRS) for capsular contraction syndrome (CCS). Methods In a retrospective study, 19 patients (19 eyes) who presented with CCS after cataract phacoemulsification with IOL implantation underwent CBRS. Eleven patients (11 eyes) underwent surgery for a radial incision relaxing procedure and 8 patients (8 eyes) underwent a second continuous curvilinear capsularrhexis (CCC). Uncorrected visual acuity and best corrected visual acuity of the surgically treated eyes were checked postoperatively and compared with their preoperative uncorrected vision. A slit-lamp biomicroscope was used to observe the change in the size of the transparent zone of the anterior capsule holes, the condition of the anterior and posterior capsules, and the IOL position. Patients were also assessed for whether or not they experienced subjective symptoms such as glare or simple blur. Patients were followed up for 6 months. Results There were different degrees of improvement in visual acuity postoperatively in all surgically treated eyes (Wilcoxon signed rank test, U=5.435, P<0.01). Glare or simple blur disappeared and patients could see more clearly postoperatively. Slit-lamp examination showed that the capsular sac contraction had relaxed, the sizes of the transparent zones of the anterior capsule were enlarged and the position of the IOL was stable and centered in all surgically treated eyes. Conclusion CBRS is an effective method for patients with CCS, visual acuity improved, subjective symptoms disappenred, the position of IOL stabled.
