Significance: Consistent with closed loop models of regulated eye growth, a successful dual-focus (DF) myopia control contact lens focused a significant proportion of light anterior to the central retina in eyes of treated children viewing near and distant targets. Purpose: This study examined the optical impact of a DF contact lens during near...
Article
Full-text available
Purpose: Personal mobile devices such as smartphones are proving their usefulness in ever more applications in tele-eyecare. An inconvenience and potential source of error in these past approaches stemmed from the requirement for the subjects to situate their devices at a distance. The present study aims to clinically validate best corrected visua...
Article
Purpose: To quantify the amount of myopic defocus, contrast modulation and other optical characteristics of two novel spectacle lenses (MiYOSMART by Hoya and Stellest by Essilor) with the inclusion of lenslets in their designs were investigated computationally and experimentally. This paper examined the hypothesis that despite the non-coaxial natu...

Novel zonal multifocal contact lens designs are sophisticated. Such lenses can be measured on-eye and ex-vivo using aberrometers, but traditional methods of representing them (e.g. polynomials) are not adequate. Peripheral vision (important for myopia control) requires accurate off-axis measures, which suffer from different error sources: parallax,...
Article

Purpose: To evaluate the refractive impact of dual-focus (DF) myopia control contact lenses (CLs) on accommodating young myopic adults. Methods: Phase 1: accommodative accuracy was assessed in 40 myopic participants. Phase 2: a subset of four subjects who demonstrated accurate accommodation and six who chronically underaccommodated were fitted w...

http://www.journalofoptometry.org/en-influence-angle-kappa-on-optimal-avance-S1888429620300868 Purpose: to evaluate the effects of kappa angle and intraocular orientation on the theoretical performance of asymmetric multifocal intraocular lenses (MIOL). Methods: For a total of 21 corneal aberrations, a computational analysis simulated the implan...
Article
Purpose High sampling density optical metrology combined with pupil‐ and image‐plane numerical analyses were applied to evaluate a novel spectacle lens containing multiple small zones designed to slow myopia progression. Methods High‐resolution aberrometry (ClearWave, www.lumetrics.com) was used to sample wavefront slopes of a novel spectacle lens...

Purpose The human eye exhibits large amounts (2.5 diopters) of longitudinal chromatic aberration (LCA). Its impact on polychromatic image quality, however, has been shown experimentally and by computer modeling to be small or absent. We hypothesized that modest changes in pseudophakic LCA created by higher and lower Abbe number materials will have...

Purpose: Part of the large increase of myopia prevalence in children is due to prolonged use of electronic screens (smartphones and tablets) at near-work distances. Myopia progression is correlated with near vision. However, there are no commercially available solutions to measure work distance in natural conditions at high acquisition rates. We de...

Purpose: Longitudinal chromatic aberration is present in all states of accommodation and may play a role in the accommodation response and the emmetropisation process. We study the change of the depth of field (DOFi) with the state of accommodation, taking into account the longitudinal chromatic aberration. Methods: Subjective DOFi was defined a...
Conference Paper
Full-text available
Purpose : We propose a new strategy that may permit the visual system to get objective information of the sign of defocus under monocular viewing conditions. It is based on the differences between the retinal images focused in front or behind the peripheral retina produced by the presence of a blood vessel network of arteries and veins in front of...

Conference Paper
Full-text available
Purpose: Recently it has been proven that spherical aberration has influence over the depth of field (DOFi) and the accommodation lag (Bernal-Molina et al., OVS, 2014). We study if the longitudinal chromatic aberration (LCA) also plays a role in increasing the DOFi during accommodation, thus providing an effectively larger range of accommodation....
