Fig. 2From: Biomechanical diagnostics of the corneaThe impact of the chamber pressure on the deformation of two different contact lenses. The toughest lens (525 μm thick with 62% hydroxyethyl methacrylate) in its natural state (a) is compared to the most pliable lens (258 μm thick with 42% methyl methacrylate) in its natural state (b). Note that each lens deforms more at higher chamber pressures and that the toughest lens deforms less when compared to the most pliable lens under the same pressure levels of 5 mmHg (c and d), 25 mmHg (e and f), and 45 mmHg (g and h). However, note the toughest lens deforms more under low pressure (c) than the most pliable lens under high pressure (h) [55]. Personal archiveBack to article page
