In this paper we describe Pellucid Agent Architecture for experience knowledge management. This architecture is suitable for public organizations, which enact administration processes. Pellucid captures knowledge from experienced employees, explores new knowledge and assists unexperienced employee by providing relevant knowledge. Pellucid spontaneously gives advices (recomended contacts, useful...

Changes in the biomechanical properties of the human cornea play an important role in the pathogenesis of corneal ectatic diseases. A variety of conditions in primary acquired (keratoconus and pellucid marginal degeneration) or secondary induced (iatrogenic keratectasia after excimer refractive laser surgery) corneal ectatic disorders lead to reduced biomechanical resistance. Corneal collagen c...

PURPOSE To determine the efficacy of the KeraSoft(®) IC (KIC) (Ultravision International Limited, Bedfordshire, UK), a silicone hydrogel contact lens, for the optical management of non-surgical corneal ectasias and to compare it with the Rose-K 2 RGP contact lens. METHODS In a retrospective study ninety-four eyes fitted with KIC (group A) were compared with seventy-seven eyes fitted with Rose...

Introduction In recent years, reduced corneal biomechanics have been identified as an important element in the pathogenesis of various corneal diseases. The biomechanical characteristics of a connective tissue such as strength and resistance against mechanical stress are indispensable prerequisites to maintain regular shape and function of that tissue. Intraand intermolecular cross-links betwee...

Purpose. To evaluate the risk factors for post-laser in situ keratomileusis (LASIK) ectasia. Materials and Methods. Medical records of 42 eyes of 28 (10 women, 18 men) patients who developed corneal ectasia after LASIK were retrospectively reviewed. Topographical features and surgical parameters of those patients were evaluated. Results. The mean age of patients was 34.73 ± 6.50 (23-48) years a...
