Cracked acrylic intraocular lens requiring explantation

BACKGROUND: Intraoperative cracking of foldable acrylic posterior chamber intraocular lenses has previously been documented. However, most cracks have resulted in no significant visual impairment. METHODS: A case report of an acrylic posterior chamber intraocular lens that cracked during folding. RESULTS: The crack in the lens resulted in significant optical disturbance and required explanation and insertion of another lens. CONCLUSIONS: Acrylic intraocular lenses must be folded carefully with appropriate forceps to prevent cracking of the optic.
