Influence of Waterproof Films on the Atomization Behavior of Surface Acoustic Waves.

One of the reasons why commercial application of surface acoustic wave (SAW) atomization is not possible is due to the condensation of aerosol droplets generated during atomization, which drip on the interdigitated transducer (IDT), thereby causing electrodes to short-circuit. In order to solve this problem, a SU-8-2002 film coating on an IDT is proposed in this paper. The waterproof performance of the film coating was tested on a surface acoustic wave (SAW) device several times.

[Hypertonic saline-assisted laser-assisted subepithelial keratectomy for the correction of moderate and low myopia].

Objective: To evaluate the effectiveness of hypertonic saline (5% sodium chloride) in execution of epithelial flap in laser-assisted subepithelial keratomileusis (HS-LASEK) for treatment of moderate and low myopia.

Methods: 48 patients (96 eyes) with moderate and low myopia were divided into 2 groups. In Group A (A-LASEK, 22 patients 44 eyes), 20% alcohol was used to create the epithelial flap; in Group B (HS-LASEK, 26 patients 52 eyes), 5% sodium chloride was used to create the epithelial flap.
