Loose zonules in cataract surgery.

PURPOSE OF REVIEW

This review will focus on identifying causes of zonulopathy during cataract surgery and discuss various modalities for treatment.

RECENT FINDINGS

There are multiple different options for capsular bag support in the setting of zonulopathy, including capsular or iris hooks, capsular tension rings as well as capsular tension segments (CTS). Surgical techniques on how to insert these devices are many and can be customized based upon the surgeon's preference and the patient's eye anatomy.

SUMMARY

Recognizing zonular weakness is critical to achieve stable postoperative vision and avoid future complications. Depending on the degree of zonulopathy, various treatment options can be pursued, ranging from capsular tension hooks or iris hooks, capsular tension rings or sutured or scleral fixated CTS.
