Corneal Biomechanics in Ectatic Diseases: Refractive Surgery Implications. [PDF]

, 2017
BACKGROUND: Ectasia development occurs due to a chronic corneal biomechanical decompensation or weakness, resulting in stromal thinning and corneal protrusion. This leads to corneal steepening, increase in astigmatism, and irregularity.
