Fig. 6From: Effects of the LASIK flap thickness on corneal biomechanical behavior: a finite element analysisRelationship between stress on the anterior and posterior corneal surfaces along the Y-axis and flap thickness. The flap thickness was set to 90, 120, 150, 180, 210, and 240 μm, respectively. Intraocular pressure was constant at 17 mmHg. a Anterior surface. b Posterior surfaceBack to article page
