Retained soft contact lens masquerading as a chalazion: A case report.

A misplaced contact lens is a common ocular emergency presenting to the eye casualty. We report a case of lost soft contact lens which migrated in the lid and presented 13 years later with symptomatic eye lid swelling. Authors in the past have reported migration and subsequent retention of lost hard lenses in locations such as the superior fornix and eyelid. To the best of our knowledge, misplaced soft contact lens masquerading as a chalazion has not been reported in the literature. Consideration should be given to the possibility of a retained contact lens in a patient with a history of a lost or misplaced lens, and examination of the ocular surface with double eversion of the upper lid should be performed.
