Patients with progressive keratoconus, pellucid marginal degeneration, or at risk for post-refractive corneal ectasia will be recruited and undergo epithelial-on corneal crosslinking with the Peschke PXL-330 system using pulsed, accelerated energy delivery. Patients will undergo monitoring for 1
Keratoconus (KC) is a progressive, non-inflammatory corneal degenerative disease. It is a pathology characterized by a progressive thinning and protrusion of the cornea that ends in a cone‐shaped cornea. This results in progressive myopia and irregular astigmatism with associated progressive loss of
Keratoconus is a bilateral, asymmetric, progressive, non-inflammatory corneal ectatic disorder that is characterized by progressive thinning, steepening and potential scaring. Usually it affects the inferior or central cornea that becomes thinner and bulges forward in a cone-shaped fashion, inducing
1. introduction 1.1 Overview of myopia and high myopia Myopia is the most common eye disease in the world . Among them, the incidence and prevalence of myopia are highest in developed countries and regions in East and Southeast Asia. It is predicted that by 2050, global myopia patients would reach 5
Patient recruitment will include a patient population of 100 individuals from 15 years to 50 years old with established keratoconus, pellucid marginal degeneration or post-LASIK ectasia determined by keratography. A solution of transepithelial riboflavin .25% will be applied every three minutes for
The purpose of this pilot study is to assess the visual outcomes of combined wavefront-guided PRK and CXL in Krumeich stage 1 and 2 keratoconic eyes. The investigators will be conducting a prospective study at the University of Ottawa Eye Institute. A total of 24 patients will be enrolled in the
Features which distinguish this trial from previous trials of combined photorefractive keratectomy (PRK) and corneal collagen cross-linking (CXL) are: a rapid, pulsed light, CXL protocol; and a treatment programming algorithm for PRK designed to target higher order aberrations only with no
This study will evaluate the results of Corneal Collagen Crosslinking (CXL) in patients with conditions that include Keratoconus, Pellucid Marginal degeneration, Post-LASIK ectasia, and patients with radial keratotomy who experience fluctuation in their vision. This is an outcomes study, all
Potential candidates will undergo a complete eye examination to determine their eligibility for treatment. Eligible subjects will be prepared for treatment in accordance with the instructions for use in the UV-X™ Illumination System Operator's Manual, including the administration of the riboflavin
Keratoconus is a corneal degeneration characterized by bilateral conical protusion and corneal thinning. The course of the disease varies from slight irregular astigmatism to severe visual impairment due to increasing protrusion and subepithelial scarring. There is no treatment available that can
