Removal of giant vernal papillae by CO₂ laser

Background: We report our experience in removing giant papillae in cases with severe vernal keratoconjunctivitis using CO₂ laser. Methods: Five cases with conjunctival giant papillae due to severe vernal keratoconjunctivitis were treated with CO₂ laser. All cases were resistant to conventional treatment. In 4 eyes, there was also an associated corneal shield ulcer. Results: In all 5 cases the procedure was uneventful. Retreatment was performed in only 2 cases because of recurrence of the papillae. No intra- or postoperative complications were observed. Interpretation: CO ₂ laser seems to be a safe method for removing conjunctival giant papillae in cases with severe vernal keratoconjunctivitis. It is also a repeatable method that enables a rapid conjunctival and corneal recovery.
