The mechanical condition of the cornea is an important but elusive property of the eye to characterize. Weakness in the cornea is thought to be one of the primary causes of corneal ectasia, a major cause of visual impairment worldwide. Corneal weakness is also important to identify in refractive
When cross-linking corneas of > 400 microns, riboflavin in a solution with high molecular weight dextran T500 is used to prevent corneal swelling during the administration of the drops and the UV treatment. However if riboflavin is applied to a cornea in a hypotonic solution (saline), then transient
Theoretical framework:
Corneal ectasia is a relative weakness in the structure of the cornea, which produces a progressive change in its shape with resultant visual distortion.
Excimer laser surface ablation can be used to re-shape the corneal profile. When the corneal shape is very irregular,
