Intervention Details:
    Device: Cionni Modified Capsule Tension Ring
    Cionni ring was used to fixate the capsular bag to the sclera and IOL was implanted in-the-bag
Detailed Description:

The introduction of endocapsular stabilising devices have significantly improved the management of zonular weakness, allowing for in-the-bag IOL implantation. The Cionni modified capsule tension ring (M-CTR) has an anterior eyelet that provides for fixation of the capsular bag without violating its integrity. Adult and pediatric studies have shown the usefulness of the M-CTR to manage zonular weakness. However, there are very few prospective studies that show the outcomes following implantation of the M-CTR and in-the-bag IOL on a longterm basis. Therefore, the investigators decided to carry out this study to report the intraoperative performance and postoperative outcomes on a longterm basis following M-CTR and in-the-bag intraocular lens (IOL) implantation.
