Abstract

Purpose: To report a rare case of spontaneous 90° rotation of a toric intraocular lens (IOL) in a patient with congenital aniridia and highlight the importance of capsular support.
Methods: An 18-year-old female with bilateral congenital aniridia presented with cataract. The left eye underwent phacoemulsification with toric IOL implantation without a capsular tension ring (CTR).
Results: On postoperative day 1, the toric IOL showed spontaneous 90° rotation from the intended axis, resulting in significant alteration of astigmatic correction. The case highlighted capsular instability in the absence of CTR.
Conclusion: Eyes with congenital aniridia are at high risk of zonular weakness and IOL instability. Use of CTR is crucial in maintaining rotational stability of toric IOLs and optimizing postoperative outcomes.
