Purpose: To compare the static and dynamic accommodative responses measured with the WAM-5500 and the PowerRef-11 autorefractors. Methods: The dynamic and static monocular accommodative responses were measured with the WAM-5500 and the PowerRef-11 instruments in thirty pre-presbyopic patients (23.66 ± 3.19 years). The spherical equivalent was measured at(More)
PURPOSE Wavefront sensors provide quite useful information on the optical quality of the eye. However, in eyes where very high-order aberrations and scattered light are prominent, wavefront sensors may overestimate retinal image quality. This study showed that, in those cases, the double-pass technique is a complementary tool for better estimation of ocular(More)
In this paper, we analyze a color visualization system for multispectral images belonging to the near-infrared region (NIR, 800-1000 nm). Samples with the same appearance in the visible region can differ in the NIR and can be differentiated by taking into account the extra information included in this region. Using a multispectral system, five different(More)
PURPOSE To evaluate the intra- and intersession repeatability of the optical quality parameters provided by the Optical Quality Analysis System (OQAS), which is based on the double-pass technique. METHODS We performed optical quality measurements using the OQAS on 20 eyes of 10 healthy subjects who had best spectacle-corrected visual acuity of 20/20 or(More)
PURPOSE To evaluate intersession and intrasession repeatability of aberration data obtained with a new visual simulator based on adaptive optics, which includes a Hartmann-Shack aberrometer (Adaptive Optics Vision Analyzer; Voptica S.L., Murcia, Spain). METHODS Thirty-one healthy right eyes were included in the study. To evaluate intrasession(More)
