A case is presented of a patient with an unexpected poor visual result and subsequent correction following cataract removal surgery via phacoemulsification and intraocular lens implantation using a toric intraocular lens implant (IOL). The initial operation resulted in an uncorrected vision of 20/100 (0.70 logMAR). Retrospective analysis of the patient’s corneal topography revealed irregular astigmatism secondary to remote trauma to the cornea. The cylinder axis on manifest refraction (MR) was significantly different from measured keratometry, so a second procedure was performed to align the cylinder axis of the IOL with the steep axis on MR. This repositioning procedure improved visual outcome to a final uncorrected vision of 20/25 (0.10 logMAR) and best corrected acuity of 20/20 (0.0 logMAR).
