A 40-year-old woman experienced recurrent granular corneal dystrophy in the left eye 18 years after undergoing penetrating keratoplasty (PK). Her uncorrected visual acuity was 20/4000 while her best-corrected visual acuity was 20/200 with manifest refraction of −12.00-2.25 × 100. Slitlamp microscopy and anterior-segment optical coherence tomography results demonstrated superficial corneal stromal opacities (Figure, A). Phototherapeutic keratectomy with photorefractive keratectomy was performed, and the ablation zone of the corneal graft became transparent. At 4 months, no haze was observed (Figure, B). Her uncorrected visual acuity improved to 20/100; her best-corrected visual acuity reached 20/33. The manifest refraction was −4.0-3.50 × 100.
