The toric IOL axis was measured 3 weeks postoperatively by rotating the slitlamp beam to align with the IOL axis indicator marks and using the Internal OPD Map on the Nidek OPD-Scan system. Uncorrected (UDVA) and corrected (CDVA) distance visual acuities, residual retractive sphere, and residual keratometric and refractive cylinders were also measured at 3 weeks.
RESULTS: Postoperatively, the mean UDVA was 0.17 logMAR +/- 0.18 (SD) and the mean CDVA, -0.01 +/- 0.12 logMAR; 88.2% of eyes had a UDVA of 0.3 or better, and no eye lost lines of visual acuity. There was an 82.33% reduction in defocus equivalent and a 64.62% reduction in refractive cylinder.
The mean IOL misalignment measured by slitlamp Selleck VX-770 was 2.55 +/- 2.76 degrees and by the internal
map, 2.65 +/- 1.98 degrees. The correlation between the 2 methods was highly significant (r = 0.99, P<.001).
CONCLUSIONS: Both refractive power/corneal analyzer system and slitlamp observation were reliable and predictable methods of assessing IOL alignment. The 4-point preoperative marking technique yielded clinically acceptable, accurate toric IOL alignment.”
“The effect of functionalized polyphosphazene on the thermal, rheological, and morphological properties of PPO (poly(phenylene oxide))/liquid crystalline polymer (Vectra A) blend has been investigated by means of the capillary rheometry, mechanical testing, and scanning electron microscopy (SEM) in this Selleckchem ALK inhibitor study. The rheological measurements show that compatibilized blends
exhibit substantial rise in viscosity in comparison to uncompatilized blend especially pronounced at lower shear rates which results in improved interfacial adhesion. DMA study highlights that polyphosphazene could be used as Sotrastaurin an effective compatibilizer for the concerned blend system. SEM study reveals fine fibrillation of liquid crystalline polymers in presence of compatibilizer and the fibers are oriented in the direction of flow field. The mechanical properties of the ternary blends are increased when a proper amount of polyphosphazene is added. This is attributed to fine strand generation induced via the addition of polyphosphazene. Enhanced adhesion at the interface invokes better elongation in the ternary blends. However, mechanical properties deteriorate considerably when polyphosphazene content is 5 wt %. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 119: 1914-1922, 2011″
“Inspired by recent progress of experimental fabrication of carbon structure [Borrnert et al., Phys. Rev. B 81, 085439 (2010)], we proposed a scheme to generate spin-polarized current based on an all-carbon system consisting of carbon nanotube and chain. The transmission spectra are calculated based on density functional theory combined with nonequilibrium Green’s function method.
