Corneal hysteresis using the Reichert ocular response analyser: findings pre‐ and post‐LASIK and LASEK

Abstract

Corneal hysteresis decreased following LASIK and LASEK. Similar reductions occurred following both procedures, indicating that LASIK involving a thin 120-mum flap did not induce additional biomechanical change. Postoperative reduction in hysteresis did not correlate with the amount or percentage of corneal tissue removed, nor with optical zone or patient age.
