Enhanced Screening for Ectasia Risk prior to Laser Vision Correction

Abstract

Aim: To prospectively review current understanding and future trends of screening for keratectasia risk prior refractive laser vision correction (LVC). Background: Progressive keratectasia is an uncommon but severe complication of LVC. Preoperative ectatic corneal disease is the most important risk factor. Screening for sub-clinical ectasia relies on proper interpretation of advanced diagnostic technologies, including front surface corneal topography, three-dimensional tomography, and biomechani-cal assessments.
