Reactive lymphoid hyperplasia one month after LASIK surgery

Background: To describe a case of reactive lymphoid hyperplasia following laser assisted in situ keratomileusis (LASIK). Methods: This observational case report describes a 31-year-old man who underwent LASIK and presented 1 month later with a fleshy, conjunctival (plical) tumour in the left eye. An excisional biopsy of the tumour was performed. Results: Histopathology of the excised tumour revealed reactive lymphoid hyperplasia involving the left conjunctiva. Discussion: Conjunctival lymphomas can masquerade as chronic conjunctivitis and can be preceded by reactive lymphoid hyperplasia. It is important to identify and differentiate these tumours. This report describes the unusual occurrence of a lymphoid conjunctival tumour after LASIK eye surgery.
