Undercorrection after photorefractive keratectomy in Wilson's disease

A 34-year-old woman with Wilson’s disease and prominent Kayser–Fleischer rings had uncomplicated photorefractive keratectomy (PRK) in both eyes. Her preoperative refraction was −3.25 −2.50 × 180 in the right eye and −3.25 −1.50 × 180 in the left eye. The corneal topographic pattern showed symmetric bow tie with-the-rule astigmatism, and central corneal thickness was 550 μm in both eyes. Three months postoperatively, her refraction was −1.00 −1.25 × 180 in the right eye and −1.50 −1.00 × 180 in the left eye. The following enhancement surgery resulted in a stable and satisfactory refraction in 2 years. We conclude that Wilson’s disease might not be a contraindication for PRK.
