The corneal topographer is an indispensable tool and plays a critical role in the practice of refractive surgery. In corneal refractive surgery, corneal topography is used preoperatively to detect irregular astigmatism, ectatic corneal disorders, or other abnormalities, and to monitor topographic stability following discontinuation of contact lens wear. Postoperatively, it is used to monitor an...

S. Lasek, E. Mazancová, VŠB-Technical University of Ostrava, FMMI Czech Republic In this paper corrosion properties of X70MnAl28-9 TRIPLEX steel were tested after hot rolling and subsequent aging at 500 °C for 6, 30 and 60 min. and at 600 °C for the same times. For comparison related steels(X100MnAl28-12, X70Mn22, C20) were also used. The microstructure wascharacterized by light microscopy, SEM...

Dear Editor, Peripheral corneal infiltrates are associated with several causes, including infectious keratitis, staphylococcal marginal keratitis, and peripheral keratitis related with autoimmune disease or contact lenses [1,2]. Peripheral corneal infiltrates after corneal refractive surgery are rare, and most of them are bilateral [1,2]. We report a case of unilateral peripheral infiltrates th...

Introduction: Traditional therapy for anisometropic amblyopia often fails when severe anisometropia is present. Recent advances in refractive surgery for anisometropic amblyopia suggest that surgical treatment may be a viable alternative in certain situations. Methods: The potential indications for refractive surgery for anisometropia, the different refractive procedures available, and the risk...

We present a case of successful multi-procedure management of a patient with an open globe injury. A 47-year-old man sustained an injury to his left eye caused by glass fragments of his own spectacles shattered while he was protecting an unknown woman from physical assault at a bus stop. Over a span of 65 months the patient underwent multiple procedures including primary wound repair, penetrati...

The category-order effect is observed when stimuli from a small, homogenous category are presented before a large, heterogeneous category (Greene & Lasek, 1994). Schoenherr and Thomson (2008) determined that the category-order effect was a product of the phonotactic properties of the category, facilitating recall in situations that were not consistent with Greene and Lasek’s account. In the pre...
