title: Modified capsule expander implantation to reposition and fixate the capsular bag in eyes with subluxated cataractous lenses and phacodonesis: intermediate-term results.
abstract: OBJECTIVE
  To report the intermediate-term results of capsule stabilization for scleral fixation with implantation of the Yaguchi hook, a modified capsule expander stabilization hook.
  
  
  METHODS
  Department of Ophthalmology, School of Medicine, University of Showa, Fujigaoka Rehabilitation Hospital, Yokohama, Japan.
  
  
  METHODS
  Retrospective case series.
  
  
  METHODS
  Patients with zonular dialysis and phacodonesis were followed postoperatively for at least 2 years. All eyes had phacoemulsification and aspiration using an ordinary capsule expander and in-the-bag implantation of an intraocular lens (IOL). Capsule expanders were removed after the residual cortex was removed, and the capsular bag was fixated to the scleral wall via the ciliary sulcus using the modified capsule expander stabilization hook. Preoperative findings, intraoperative complications, and postoperative courses were examined.
  
  
  RESULTS
  The mean age of the 11 patients (11 eyes) was 72.2 years ± 10.5 (SD); 5 patients were men. The mean postoperative follow-up was 48.6 ± 13.6 months. The zonular dialysis range was 90 to 180 degrees in 1 eye, 180 degrees in 4 eyes, and 180 to 270 degrees in 1 eye. In 5 eyes, severe phacodonesis was observed without obvious zonular dialysis. In all eyes, the capsular bag and IOL were well centered without severe intraoperative or postoperative complications.
  
  
  CONCLUSIONS
  The modified capsule expander stabilization hook provided good centration and stabilization of the capsule-IOL complex in eyes with severely weak zonular fibers.
