Perforation by a foreign body through a pre-existing radial keratotomy wound.

A case is presented demonstrating selective perforation of a foreign body through a pre-existing partial thickness radial keratotomy wound. This is the initial documentation of a distinct type of injury to which an eye is susceptible following corneal refractive procedures. Despite the excellent outcome, the occurrence of this injury in a soldier during a field training exercise provides additional justification for current Army policy of barring the induction of enlistees who have undergone corneal surgery to correct refractive errors.
