We present the case of a patient who experienced recurrent episodes of blurry vision and eye pain after uneventful cataract extraction and in-the-bag intraocular lens (IOL) implantation. Examination revealed a microhyphema and signs of pigment dispersion. Iris transillumination was seen overlying areas where the IOL optic was not covered by the anterior capsule. Anterior segment optical coherence tomography confirmed iris indentation by the IOL optic, which was alleviated by performing laser peripheral iridotomy. This case shows that IOLs in the capsular bag can erode the posterior surface of the iris and that an adequately sized capsulorhexis should be performed to ensure anterior capsule coverage. Laser peripheral iridotomy should be considered when significant posterior iris bowing is observed.
