title: Customized ultra-high-power toric intraocular lens implantation for pellucid marginal degeneration and cataract.
abstract: I report a case of pellucid marginal degeneration (PMD) with cataract that was successfully treated with implantation of an ultra-high-power customized bitoric AT.Comfort 646TLC intraocular lens (IOL). The preoperative uncorrected distance visual acuity (UDVA) was 6/120 and the corrected distance visual acuity (CDVA), 6/24 with 10.9 diopters (D) of keratometric astigmatism on Scheimpflug imaging. After implantation of an IOL with -0.5 +16.0 x 170, the UDVA was 6/9 with a manifest refraction of +0.25 +1.25 x 150 and the CDVA, 6/6(-1). No surgical complications or postoperative problems occurred, and the patient was very satisfied with the outcome. A longer follow-up is required to confirm this favorable clinical result.
