Iatrogenic keratectasia after a deep primary keratotomy during laser in situ keratomileusis.

Abstract

To describe a case of keratectasia after a deep primary keratotomy during an aborted laser in situ keratomileusis procedure. Retrospective, observational case report. In a 47-year-old woman, progressive keratectasia developed after a 90% depth keratotomy during an aborted laser in situ keratomileusis procedure. This case was managed with a rigid gas permeable contact lens and consideration for penetrating keratoplasty. Keratectasia is a reported microkeratome-related complication after laser in situ keratomileusis. Appropriate microkeratome assembly and surgeon awareness are necessary to avoid this complication.
