In cataract surgery for eyes with weak zonules, it is commonly assumed that a capsular tension ring (CTR) cannot prevent late subluxation or dislocation. But is this belief entirely accurate? Utilizing high-resolution intraocular endoscopy, we have shown that, in select cases, a CTR inserted into the capsular bag can engage with the ciliary sulcus, effectively stabilizing the capsule and IOL.
