The progression of myopia is thought to be controlled by the retinal image quality, but its
triggering factors are not yet well known. The differences between the peripheral optics in …

We designed and built a fast scanning peripheral Hartmann-Shack (HS) wave-front sensor
to measure the off-axis wave-front aberrations in the human eye. The new instrument is …

A Shack–Hartmann wavefront sensor was modified to allow measurement of ocular
aberrations in downward gaze with binocular fixation. Subjects first performed a control task …

Purpose. To investigate the tolerance to lateral pupil misalignment in peripheral refraction
compared with central refraction. Methods. A Shin-Nippon NVision-K5001 open-view auto …

Purpose The purpose of this study was to theoretically model the contributions of corneal
asphericity (Q) and anterior chamber depth to peripheral wavefront aberrations. Methods …

The schematic of Figure 21.1 is highly simplified, assuming spherical and aligned surfaces.
Nevertheless, it demonstrates two important facts regarding the optical errors of the human …

Purpose To investigate normal anterior segment parameters and analyze the possible
influencing factors using a dual Scheimpflug system. Setting Department of Ophthalmology …

There is an increasing interest in measuring the peripheral optical quality of the eye. Optical
aberrations have been studied extensively in the center of the visual field due to the …

To better understand how peripheral refraction affects development of myopia in humans,
specialized instruments are fundamental for precise and rapid measurements of refraction …

Changes in corneal optics have been measured after downward gaze. However, ocular
aberrations during downward gaze have not been previously measured. A commercial …
