Spherical Aberration Changes in Patients With Early Presbyopia Wearing Aspheric Multifocal Soft Contact Lenses in South Korea.

Objectives: The aim of this study was to evaluate the impact of wearing center-near (CN) and center-distance (CD) multifocal contact lenses (MFCLs) on spherical aberrations and visual acuity in patients with early presbyopia.

Methods: Fifty participants with early presbyopia wore CN-MFCLs and CD-MFCLs for 1 week. The average corrected refractive power was -2.

Age-specific influences of refractive error and illuminance on pupil diameter.

To assess the most influential factor for pupil diameter changes among age, illuminance, and refractive state and reestablish the optimal procedures for clinical applications based on refractive state and illuminance for different age groups. The study was an observational study (repeated measure study). Participants included 219 Korean adults aged 20 to 69 years.

Gait characteristics during crossing over obstacle in patients with glaucoma using insole foot pressure.

Background: Glaucoma, is the most common cause of irreversible visual deficits, presents as an injury to the optic nerve and it is mainly associated with elevated intraocular pressure. The main symptom of glaucoma is a reduction of the visual field, which is usually a source of complaint at the advanced stage of disease. Because of visual deficit, gait dysfunctions, including low gait speed and increased bumping into objects, postural sway, and falling are occurred.

Accelerating repaired basement membrane after bevacizumab treatment on alkali-burned mouse cornea.

To understand the corneal regeneration induced by bevacizumab, we investigated the structure changes of stroma and basement membrane regeneration. A Stick soaked in 0.5 N NaOH onto the mouse cornea and 2.

Central corneal thickness and corneal endothelial cell changes caused by contact lens use in diabetic patients.

Purpose: To analyze the effects of soft contact lenses on central corneal thickness and morphologic characteristics of the corneal endothelium in diabetic patients.

Materials And Methods: Ultrasound pachymetry and noncontact specular microscopy were performed on 26 diabetic patients who regularly use soft contact lenses (group 1), 27 diabetic patients who do not use soft contact lenses (group 2) and 30 normal subjects (group 3). We compared the values in each group using the Mann-Whitney test.

Valosin-containing protein is a novel autoantigen in patients with glaucoma.

Purpose: The purpose of this study was to identify novel autoantigens that react with specific serum autoantibodies in patients with glaucoma.

Methods: Sera from patients with glaucoma (n = 80) and healthy subjects without a known pathology (n = 20) were investigated by immunoblot performed with bovine optic nerve lysates and resolved by one- and two-dimensional electrophoresis. Proteins in the immunoreactive spots were selected and identified by liquid chromatography-tandem mass spectrometry (LC-MS/MS) data analysis.
