Inaccuracy of intraocular lens power calculation after traumatic corneal laceration and cataract

A 53-year-old man sustained a perforating, central corneal injury with a na il in his right eye. After primary repair of the laceration, a traumatic ca taract was removed and a Multiflex-style intraocular lens (IOL) was inserte d. A 4.00 diopter surprise resulted, probably due to calculation of the IOL power using measurements from the contralateral normal eye. Inability to w ear a contact lens for visual correction resulted in IOL exchange surgery i n which a sulcus-sutured IOL was implanted. The IOL power was calculated us ing simulated keratometry from videokeratoscopy and axial length measuremen ts of the injured eye, This resulted in an IOL power closer to emmetropia, allowing for a best spectacle-corrected visual acuity of 20/20 and comforta ble wearing of spectacles.
