F or 3 years the International Congress of Corneal Cross Linking was hosted in Zurich, Switzerland by its founders, Theo Seiler, Hans Peter Iseli, and Michael Mrochen. Last year, the Congress was moved to Dresden, Germany, the home of Eberhard Spoerl, where corneal cross-linking (CXL) fi rst began. The Congress was held on December 5-6, 2008, and as with the previous 3 years, this meeting had h...

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...

surgery has opened up the possibility to change the corneal curvature to compensate for refractive errors of the eye. In the case of small spot hyperopic laser in situ keratomileusis (H–LASIK), excimer laser systems produce a steepness of the cornea by ablating mainly at the periphery of the cornea. Hyperopic laser in situ keratomileusis (H-LASIK) treatments induce aberrations1. Other studies2,...

PURPOSE Previous work has suggested a major role of scleral biomechanics in the pathogenesis of glaucoma. Since fiber orientation in connective tissues is a key determinant of tissue biomechanics, experimental characterization of scleral fiber orientation is needed to fully understand scleral biomechanics. This is a report of baseline experimental measurements of fiber orientation in whole norm...

purpose: to investigate the biomechanical features of transplanted corneas after penetrating keratoplasty (pk), deep anterior lamellar keratoplasty (dalk), and descemet stripping automated endothelial keratoplasty (dsaek) and compare these measurements with those of a normal group. methods: forty-five eyes of 36 patients underwent pk, 23 eyes of 21 patients received dalk using anwar’s big bubbl...
