Purpose: To report the formation of the continuous curvilinear capsulorhexis (CCC) window in cases of intraocular lens (IOL)–Capsular Tension Ring (CTR) complex dislocation, determine appropriate indications for using CTRs, and evaluate surgical techniques for repositioning of the dislocated IOL–CTR complex. Methods: Four consecutive patients who underwent IOL repositioning surgery for IOL–CTR complex dislocation were followed-up postoperatively. CCC formation was analyzed using images captured during surgery and calculating software available for free. Results: IOL–CTR complex dislocation had occurred from 2 to 120 months after initial cataract surgery. Repositioning surgery was completely performed with modified capsule expander (Yaguchi hook). The mean oblateness was 0.056 ± 0.053 (range, 0.002–0.14), indicating that CCC contours of dislocated IOL–CTR complex is approximately similar to circle formation. Conclusions: CTR implantation is effective in maintaining the capsular formation postoperatively. The use of Tshaped capsule stabilization hook (Yaguchi hook) provided good centralization and stabilization of the IOL–CTR complex in eyes with severely weak zonular fibers providing a simple technique for repositioning of the dislocated complex via a corneal side port without IOL extraction.
