Corneal ectasia is a serious vision-threatening complication of laser in situ keratomileusis (LASIK). It is associated with progressive corneal steepening, an increase in myopia and astigmatism, and decrease in uncorrected visual acuity. Before LASIK presence of risk factors (corneal thickness, refractive error, presence of clinical and subclinical corneal pathologies) should be studied so pati...

PURPOSE Corneal thinning disorders weaken the mechanical strength of affected corneas, suggesting that photorefractive procedures may be contraindicated in keratoconus. Few cases have been reported to confirm this hypothesis. METHODS A 45-year-old man had two laser in situ keratomileusis (LASIK) procedures and one photorefractive keratectomy (PRK) performed on his left eye, and three LASIK pr...

Keratoconus and other corneal conditions associated with progressive stromal thinning including keratectasia after laser-assisted in situ keratomileusis (LASIK) and pellucid marginal degeneration represent therapeutic challenges. Until recently, available therapies including contact lenses, epikeratoplasty, intrastromal corneal rings, and corneal transplantation targeted, in principle, the abno...

PURPOSE To report an interesting case of concomitant bilateral Terrien's marginal degeneration-like corneal ectasia and posterior polymorphous corneal dystrophy in a young man with quiescent rheumatoid arthritis. CASE REPORT A 24-year-old man with history of rheumatoid arthritis presented with bilateral decreased vision since four years ago. Slit lamp examination revealed bilateral circumfere...

In this paper we present how agent technology can be used to improve Administration Based Processes. We introduce Pellucid Agent Architecture, which can assist organizationally mobile public employees. The presented architecture was created as a part of the European Union IST Project named Pellucid.

In this paper we present how agent technology can be used to improve Workflow Management Systems. We propose Pellucid Agent Architecture which helps with Workflow Process creation and with integration Intra Organizational Workflow. Proposed architecture was created as a part of European Union IST Project named Pellucid.
