Fig. 3From: Effects of the LASIK flap thickness on corneal biomechanical behavior: a finite element analysisa Relationship between corneal vertex displacement and corneal flap thickness. Intraocular pressure ranged from 15 to 49 mmHg. b Relationship between the anterior corneal surface displacement along the Y-axis and corneal flap thickness. The corneal flap thickness was assumed to be 90, 120, 150, 180, 210, and 240 μm, respectively. The unit of corneal vertex displacement was μmBack to article page
