A 15-year-old girl with hemifacial microsomia was observed since the age of 3 years. She had left-sided amblyopia, anisometropia, exotropia, ptosis with lagophthalmos, exposure keratopathy, and retinal and iris colobomas.Previous treatment included spectacles, patching, and penalization for amblyopia, strabismus surgery, and ocular lubrication. Her Snellen visual acuity maximized at 20/60 OS at the age of 6 years. She developed a dendritic corneal lesion at the age of 11 years, which was presumed to be herpetic. She was treated with acyclovir and topical corticosteroids. The active corneal lesion stabilized, but the patient continued to have a heavily vascularized corneal scar (Figure 3) and her visual acuity decreased to 20/200 because of the opacity and irregular astigmatism. She underwent 4 treatments with a yellow dye laser, with improvement in visual acuity to 20/70, with − 1.25 + 1.5 × 90°, and markedly decreased corneal vascularization (Figure 4).
