Purpose:
To report a new technique for safely and quickly removing a displaced capsular tension ring from the vitreous cavity.
Design:
Two interventional case reports.
Participants:
The authors retrospectively reviewed the charts of two patients with displaced capsular tension rings (CTRs).
Intervention:
Surgical removal of the displaced CTRs was performed in two patients.
Main Outcome Measures:
Visual and anatomic outcomes.
Results:
The CTRs were removed surgically, in case 1 by cutting the CTR into two pieces before removal and in case 2 by using the CTR injector to remove the CTR in one piece through a sclerotomy site. Both patients had good visual and anatomic outcomes.
Conclusions:
The described technique of removing a displaced CTR in one piece through a sclerotomy site using the CTR injector provides a safe and efficient method of CTR removal. Cutting the CTR into two or more pieces for removal is not recommended.
