   Nyckelord :Scheimpflug photography; back scattered light; cataracts; human lens nuclear opacities; aqueous suspension of polystyrene spheres; standard of opacity;

   Sammanfattning : Cataract is the most prevalent blinding eye disease. Scheimpflug photography is an objective method for documentation of lens nuclear opacity. Using the Scheimpflug slit-lamp technique, a photograph, in focus from the anterior surface of the cornea to the posterior surface of the lens, can be obtained. LÄS MER

3. 2. New methods to evaluate the effect of conventional and modified crosslinking treatment for keratoconus

   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Keratoconus; crosslinking; light scattering; densitometry; keratometry; hysteresis; intraocular pressure; oftalmiatrik; Ophtalmology;

   Sammanfattning : Background: Today corneal crosslinking with ultraviolet-A photoactivation of riboflavin is an established method to halt the progression of keratoconus. In some cases, when the refractive errors are large and the visual acuity is low, conventional corneal crosslinking may not be sufficient. LÄS MER
