title: Postoperative rotation of supplementary sulcus-supported toric intraocular lenses.
abstract: We describe 7 cases in which supplementary sulcus-based toric intraocular lenses (IOLs) rotated postoperatively, requiring surgical realignment. The initial rotation was identified clinically between 3 months and 36 months postoperatively. All eyes had keratoconus, with and without prior keratoplasty, and 6 had longer than average axial lengths. No preceding trauma could be identified for 5 of the eyes. One eye had 3 episodes of postoperative IOL rotation, eventually requiring suture fixation to stabilize the IOL. This series indicates that postoperative rotation of a supplementary sulcus-based toric IOL may occur in eyes with or without preceding trauma. Eyes with keratoconus are at risk for postoperative rotation of the IOL, and suture fixation may be required to obtain stability.
