METHODS: This study evaluated eyes that had implantation of a toric pIOL. Outcome measures were the uncorrected (UDVA) and corrected (CDVA) distance visual acuities (Snellen decimal), refraction, and postoperative complications.

RESULTS: The study included 15 eyes of 12 patients (9 women). Preoperatively, the mean manifest spherical refraction was -1.98 diopters (D) PXD101 clinical trial +/- 1.32 (SD) (range -0.50 to -5.50 D) and the mean refractive cylinder, -4.85 +/- 0.83 D (range -6.50 to -4.00 D). At 12 months, the mean refractive

cylinder was -0.55 +/- 0.52 D (range -1.50 to 0.00 D), with 93.3% of eyes having less than 1.00 D of cylinder. The mean spherical equivalent was -0.31 +/- 0.42 (range -1.00 to 0.75 D), with more than 70% of eyes within +/-0.50 D of the target. For the astigmatic components, 93.3% of eyes were within +/-1.00 D of J0 (r(2) = 0.98)

and all eyes were within +/-1.00 D of J45 (r(2) = 0.98). The mean UDVA was 0.70 +/- 0.20 and the mean CDVA, 0.83 +/- 0.12. The overall efficacy index was 0.90. Postoperatively, all eyes had unchanged CDVA or gained 1 or more lines.

CONCLUSION: The refractive outcomes and improvement in UDVA and CDVA were rapidly achieved and remained fairly consistent throughout the follow-up period, supporting the use of toric pIOLs in eyes with https://www.selleckchem.com/products/AC-220.html high astigmatism.”
“A theoretical investigation on capacitive properties of Fe/MgO/Fe trilayers is presented where there is a dc coupling between the two conductors. It is discussed that capacities of the nanoscale metal/insulator/metal contacts are mainly determined by the electronic charge screening at surfaces of their electrodes. The interface effects are simulated

using fixed spin moment calculations. In order to have a comparison between the capacities for the parallel and antiparallel alignments of the trilayer, it is assumed that the charge induction across the junction occurs in two independent channels corresponding to the up-and down-spin electrons. The calculations give a larger capacitance for the antiparallel alignment of the electrodes, even though the stable phase of the tunnel junction in the absence of any externally applied magnetic field is calculated to be ferromagnetic.

“PURPOSE: To evaluate alterations in corneal power parameters after Descemet-stripping automated endothelial keratoplasty (DSAEK) using rotating Scheimpflug imaging.

SETTING: University of Texas, Southwestern Medical Center, Dallas, Texas, USA.

METHODS: Eyes that had DSAEK were evaluated with a rotating Scheimpflug imaging system (Pentacam). The outcome parameters were mean anterior and posterior keratometry (K), mean anterior radius of curvature and posterior radius of curvature, anterior and posterior astigmatism, central corneal thickness (CCT), true net power, corneal volume, keratometric power deviation, and mean zonal-equivalent K readings.
