Fig. 4From: Effects of the LASIK flap thickness on corneal biomechanical behavior: a finite element analysisa The relationship between corneal vertex displacement and intraocular pressure. The flap thickness was set at 90, 120, 150, 180, 210, and 240 μm, respectively. The unit of the corneal vertex displacement was μm. b The relationship between displacement of the anterior corneal surface along the Y axis and intraocular pressure. IOP ranged from 15 to 49 mmHgBack to article page
