Spontaneous disinsertion of a haptic from a 3-piece acrylic foldable intraocular lens after surgery

A 49-year-old man with cataracts had uneventful phacoemulsification, continuous curvilinear capsulorhexis, and implantation of an MA30BA acrylic foldable intraocular lens (IOL) in the bag. One week later, 1 haptic spontaneously dropped off and the optic dislocated into the anterior chamber. The IOL was surgically removed and replaced with a new acrylic foldable IOL. Examination of the explanted IOL revealed that the loop hole was not created in the middle of the side face, leading to in vivo detachment of the haptic postoperatively.
