Evaluation of Corneal Biomechanical Properties Modification after Small Incision Lenticule Extraction Using Scheimpflug-Based Noncontact Tonometer

Table 1

Percentage variation from baseline values of the three parameters measured (millisecond (ms) in applanation times and millimeter (mm) for deformation amplitude) expressed as mean and standard deviation (S.D.) for each of the three time points. The three time points were compared using a two-tailed paired -test.
