LASIK flap interface deposition in limbal vernal keratoconjunctivitis.

Limbal vernal keratoconjunctivitis (VKC) is an uncommon chronic allergic eye disease. It is generally seen in young males and is characterised by limbal papillae and superficial keratitis. While the condition usually resolves with age, treatment is necessary to alleviate symptoms and reduce the risk of permanent corneal damage. A 25-year-old male presents with recurrent red, itchy eyes. He had undergone an uncomplicated bilateral LASIK procedure five years previously. Slitlamp examination shows limbal chemosis, superficial keratitis and an unusual yellow-white deposition that tracks along the superior LASIK flap interface. A diagnosis is made of limbal VKC with an altered corneal response associated with previous LASIK. Treatment with intensive topical steroids led to resolution of his limbal and corneal inflammation, leaving the deposition unchanged.
