(A) Corneal findings of the patient’s OD at first presentation in our clinic in 2014. Subepithelial and stromal depositions and opacities are typical in macular corneal dystrophy. BCVA was 20/50 in the OD and 20/40 in the OS. (B) Status of the cornea of the OD in February 2020 before penetrating keratoplasty. In 2019, the patient had a PTK performed in Turkey. Lesions appear to have increased in the area of the PTK and corneal opacity was present. The patient reported a severe vision loss and blurry vision as well as a burning sensation of the eyes. BCVA was decreased to 20/400 in the OD and 20/320 in the OS. (C) Cornea of the OD in June 2020, 4 months after penetrating keratoplasty. The graft was clear, fine neovascularisations were visible on the upper corneal rim. BCVA had restored to 20/40 in the OD. In the OS, BCVA was 20/80. (D) Cornea of the OD in September 2021, 19 months after penetrating keratoplasty. The two sutures had been removed after 15 and 16 months. BCVA was 20/25 in OD and 20/200 in OS
