Evaluation of Corneal Biomechanical Properties Modification after Small Incision Lenticule Extraction Using Scheimpflug-Based Noncontact Tonometer
Figure 1
Corvis UHS Scheimpflug camera frames of corneal response to a metered, collimated air pulse: air pulse forces cornea that underwent SMILE procedure (a) inwards through applanation into a concavity phase until it achieves the highest concavity (b). An oscillation period precedes the outgoing or returning phase. The cornea undergoes a second applanation (c) before achieving its natural shape with possible oscillation (d). White arrows indicate femtosecond laser cutting surface interface after SMILE procedure.
