Bilateral big-bubble deep anterior lamellar keratoplasty for vascularised corneal opacity in a patient with xeroderma pigmentosum.

A 16-year-old male patient diagnosed with xeroderma pigmentosum developed bilateral vascularised corneal opacities after treatment for ocular surface squamous neoplasia. The patient underwent an uneventful big-bubble deep anterior lamellar keratoplasty in both eyes. The grafts remained clear and the corrected distance visual acuity was 20/30 in both the eyes at the final follow-up visit.
