After IOL insertion with the injector, each haptic is externalized through 2 adjacent corneal incisions. A 10-0 polypropylene suture loop is made at each exposed haptic

and transscleral IOL fixation performed. This modified technique is a safe and effective way to fixate the IOL in eyes with insufficient capsule support.”
“A series of novel semi-2-interpenetrating polymeric networks (semi-2-IPNs) were prepared through blending in solution using two different polyimides, biscitraconamic acid as a precursor of biscitraconimide (MBMI) with various proportions of polyetherimide (PEI) to achieve optimum properties. Biscitraconamic acid was prepared by reacting citraconic anhydride (CA), 3,3′,4,4′-benzophenone tetracarboxylic dianhydride (BTDA) and bis(3-aminopropyl)phenyl Selleck MDV3100 phosphine (BAPPP) and it was characterized by differential scanning calorimetry (DSC), FTIR, and H-1-NMR spectroscopy. Both biscitraconamic acid and PEI were blended in N,N-dimethylacetamide ICG-001 concentration (DMAc) solution, casted and thermally cured up to 300 degrees C to give semi-2-IPNs. The MBMI/PEI semi-IPN systems were characterized by UV-Vis spectroscopy, FTIR spectroscopy and thermal techniques. The phase morphology, isothermal aging, and water uptake of semi-IPN systems have also been studied. The morphological studies on phase distribution were investigated by scanning electron microscopy (SEM). Thermal

performance of MBMI/PEI semi-IPN systems were evaluated by DSC and thermo selleck products gravimetric analysis (TGA). All the compositions of semi-IPN polyimide system were stable up to 400 degrees C and their thermal stability increased with increase in the content of PEI. Isothermal aging studies done at 300 degrees C for various time periods showed good thermo-oxidative stability. (C) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 120: 2790-2799, 2011″
“We present a laser ultrasonics experiment with imaging capabilities performed in transmission through semiconductor substrates. Such experiment provides a new kind of bulk wavefront imaging

using an ultrafast optical generation and detection scheme for gigahertz waves. The data may be viewed as two-dimensional slices of the three-dimensional acoustic wavefront revealing the basic anisotropy of the solid with 0.3 ps time resolution and 3 mu m space resolution and allowing the determination of the whole set of elastic constants for various experimental conditions. As examples, measurements are carried out in a Si(001), GaAs(001), and GaAs(111) sample at 20 and 300 K. (C)2011 American Institute of Physics. [doi:10.1063/1.3532034]“
