ABSTRACT

As an in-bag filling device, capsular tension ring(CTR)has played an important role in cataract surgery. Maintaining the circular contour of the capsular bag and improving the safety of surgery is the original intention of CTR design, and then it was found to have better effects in inhibiting posterior capsular opacity and capsular bag shrinkage, and enhancing the stability of intraocular lenses. After nearly 30a of improvement and development, CTR has been derived into a variety of types, and its clinical application has gradually expanded. In particular, CTR can be used in complex cataract surgery to reduce intraoperative risk and improve postoperative outcomes. In the present paper, the implantation timing, indications and complications of CTR were summarized, and the progress in clinical application in recent years was briefly reviewed.
