Collagen Crosslinking With Ultraviolet-A in Asymmetric Corneas (2)
To evaluate the efficacy of ultraviolet-A (UVA)-induced cross-linking of corneal collagen (CXL) as a method to increase the biomechanical and biochemical stability of the cornea by inducing additional cross-links within or between collagen fibers using UVA light and the photo- mediator riboflavin. The purpose of this study is to generate data for presentation at medical meetings and for peer-review publication

A noninflammatory, usually bilateral protrusion of the cornea, the apex being displaced downward and nasally. It occurs most commonly in females at about puberty. The cause is unknown but hereditary factors may play a role. The -conus refers to the cone shape of the corneal protrusion. (From Dorland, 27th ed)
The measurement of curvature and shape of the anterior surface of the cornea using techniques such as keratometry, keratoscopy, photokeratoscopy, profile photography, computer-assisted image processing and videokeratography. This measurement is often applied in the fitting of contact lenses and in diagnosing corneal diseases or corneal changes including keratoconus, which occur after keratotomy and keratoplasty.
To describe the clinical course of keratoconus and to describe the relationships among its visual and physiological manifestations, including high- and low-contrast visual acuity, corneal...
