Abstract:

Background: We present a case of intraoperative rotation of a toric lens during cataract surgery in a patient with high irregular astigmatism as a result of keratoconus.Case
Presentation: Despite numerous attempts to stabilise intraoperatively, the intraocular lens (IOL) continued to rotate until a capsular tension ring (CTR) was inserted. Good centration and rotational stability was achieved and remained at follow-up.Conclusions: We propose the possibility of an irregularly shaped capsular bag in some patients with keratoconus and high astigmatism, potentially causing the IOL to rotate to a position that better accommodates the conformation of the capsular bag. Preoperative assessment of the shape of the capsular bag in patients with keratoconus may be beneficial in preventing intraoperative rotation of IOLs.
