In-the-bag dislocation of a hydrophilic acrylic intraocular lens.

We report a case of a dislocated hydrophilic acrylic intraocular lens (IOL) inducing astigmatism and causing chronic pain and cystoid macular edema as a result of a folded haptics, which mechanically irritated the iris. Scanning electron micrographs of the explanted IOL, including the capsular bag, showed a folded IOL haptic incarcerated in the capsular bag.
