This study will determine the efficacy of collagen cross linking for progressive keratoconus and ectasia after lasik. It will try and determine which is a more effective treatment: collagen cross linking alone or collagen cross linking combined with Intacs, a treatment which has already been proven to be effective in decreasing corneal curvature in patients with keratoconus.
Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Corneal collagen crosslinking (CXL) has been proposed as an effective method of reducing progression of both keratoconus and corneal ectasia after surgery, as well as possibly decreasing t...
Prospective, randomized, single site to determine the safety and effectiveness of performing corneal collagen cross-linking (CXL) using riboflavin and UVA light in eyes progressive keratoc...
Cross-linking of the cornea increases the mechanical and biochemical stability of the stromal tissue. The purpose of this study is to assess the effectiveness of riboflavin-ultraviolet lig...
The objectives of this study are to evaluate the safety of and efficacy of the KXL system with vibeX Rapid (Riboflavin Ophthalmic Solution) for Corneal Collagen Cross-Linking in eyes havin...
Following the Bunsen-Roscoe law, accelerated cross-linking protocols with higher irradiation intensities and shorter irradiation times have been introduced. In addition, new riboflavin sol...
Keratoconus is the primary cause of corneal transplantation in young adults worldwide. Riboflavin/UV-A corneal cross-linking may effectively halt the progression of keratoconus if an adequate amount o...
To compare intraoperative changes in central corneal thickness (CCT) during corneal cross-linking, using 2 different isotonic riboflavin solutions either with dextran or with hydroxy propyl methylcell...
Identifying potentially treatable risk factors for the progression of keratoconus is of great importance. The purpose of this study was to determine the association between blepharitis and keratoconus...
The scientific problem of epidemiology of keratoconus in different countries is covered in the article. The results of original studies were analyzed and a conclusion has been drawn that keratoconus i...
An enzyme that catalyzes the formation of riboflavin from two molecules of 6,7-dimethyl-8-ribityllumazine, utilizing a four-carbon fragment from one molecule which is transferred to the second molecule. EC 22.214.171.124.
A dietary deficiency of riboflavin causing a syndrome chiefly marked by cheilitis, angular stomatitis, glossitis associated with a purplish red or magenta-colored tongue that may show fissures, corneal vascularization, dyssebacia, and anemia. (Dorland, 27th ed)
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)
A coenzyme for a number of oxidative enzymes including NADH DEHYDROGENASE. It is the principal form in which RIBOFLAVIN is found in cells and tissues.
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.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
