Efficacy of 3% diquafosol sodium eye drops at different frequencies in the treatment of dry eye after FS-LASIK.

Aim: To compare the efficacy of 3% diquafosol sodium (DQS) eye drops at different frequencies in dry eye (DE) after femtosecond laser-assisted keratomileusis (FS-LASIK).

Methods: In this prospective study, DE patients after FS-LASIK were randomly divided into two groups. All patients were administered routine anti-inflammatory and anti-infective drugs after FS-LASIK.

[Clinical research of the phakic foldable angle-supported intraocular lens for the correction of high myopia].

Objective: To assess the safety, efficacy, predictability and stability of the phakic foldable angle-supported intraocular lens (IOL) (CACHET IOL, Alcon Inc., USA.) for correction of high-to-extremely high myopia in adults.

AcrySof phakic angle-supported intraocular lens for the correction of high to extremely high myopia: one-year follow-up results.

Aim: To assess the safety, efficacy and predictability of the AcrySof phakic angle-supported intraocular lens (IOL) (Alcon Inc., U.S.

[Performance dependence of organic light-emitting devices on the thickness of Alq3 emitting layer].

The dependence of opto-electronical characteristics in organic light-emitting devices on the thickness of Alq3 emitter layer was studied, where MoO3, NPB, and Alq3 were used as hole injector, hole transporter, and emitter/electron transporter, respectively. By increasing the thickness of Alq3 layer from 20 to 100 nm, the device current decreased gradually, and the EL spectra of devices performed a little red shift with an obvious broadening in long wavelength range but a little decrease in intensity of short wavelength range. The authors simulated the EL spectra using the photoluminescence (PL) spectra of Alq3 as Alq3 intrinsic emission, which coincided with the experimental EL spectra well.

[Experimental study of spherical aberrations of intraocular lenses with different materials and designs].

Objective: To study the characteristics of spherical aberrations (SA) of the traditional intraocular lenses (IOLs) produced by different materials and designs.

Methods: A special optical metrical system was established in the laboratory to measure the SA of IOLs by using the Hartmann-Shack aberrometer. Eight different types of IOLs were divided into two Groups.

[Application of wavefront aberration technique in the study of phakic and pseudophakic eyes].

Modern cataract surgery is routinely combined with the implantation of an intraocular lens (IOL). Although surgical technique as well as IOL materials and designs have been improved dramatically, the problems related postoperative visual acuity still occur, such as glare disability, low visual acuity at night, and so on. Wavefront aberration technique can be used to help us revealing the real reasons of such postoperative visual problems.
