Aberrometric outcome of customized toric IOL in cataract with very high corneal astigmatism due to pellucid marginal degeneration.

A case of pellucid marginal degeneration (PMD) with cataract where a customized high-power toric IOL was implanted is reported. The patient had preoperative corneal astigmatism of 13.96 diopters (D), and a customized toric IOL of 19 D toricity was implanted; postoperative visual acuity was 6/9 on Snellen chart. The visual quality and aberrometric outcome were assessed with a ray-tracing aberrometer. The toric IOL gave not only a better uncorrected visual acuity but also better quality of vision in this patient with corneal astigmatism due to PMD.
