Two male patients, aged 64 and 55 years old, presented at the cornea department for a Boston type 1 keratoprosthesis (Kpro I) implantation after multiple corneal graft failures. After surgery, they achieved a best corrected visual acuity of 20/200 and 20/150, respectively. However, they manifested photophobia and aesthetic complaints. Both patients underwent keratopigmentation to improve the aesthetic outcome using vegetable pigments, after mechanical corneal deepithelization, with no intraoperative or postoperative incidents or adverse events. After 1-year follow-up, the patients presented the same best corrected visual acuity with improvement of the aesthetic outcome.
