Purpose: To develop an optical model of a child's eye to reveal the impact of target distance and accommodative behaviour on retinal image quality when fitted with multi-zone lenses. Methods: Pupil size, aberration levels and accommodative lag were adjusted for models viewing stimuli at 400, 100, 33 and 20 cm. Distributions of defocus across the...

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,...

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...
Article
A combination of human subject data and optical modelling was used to investigate unexpected nasal-temporal asymmetry in peripheral refraction with an aspheric myopia control lens. Peripheral refraction was measured with an auto-refractor and an aberrometer. Peripheral refraction with the lens was highly dependent upon instrument and method (e.g. p...

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...
Article
Full-text available
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 hav...

Article
Significance: Measurement of ocular aberrations is a critical component of many optical corrections. Purpose: This study examines the accuracy and repeatability of a newly available high-resolution pyramidal wavefront sensor-based aberrometer (Osiris by Costruzione Strumenti Oftalmici, Firenze, Italy). Methods: An engineered model eye and a di...

Purpose: To evaluate under known, standarized conditions a novel app for remote monitoring of myopia progression in children. Vision professionals and researchers can use a cloud-connected web interface to remotely access their patients´ data: viewing distance, face illumination and sphero-cylindrical refraction obtained using myopia.app. Viewing d...

Specially developed software (app) was written for handheld electronic devices that uses the device camera and light detector for real-time monitoring of near-work distance and environmental lighting. A pilot study of this novel app employed children using tablet computers in a classroom. Measurements of face-device distance and face illuminance we...
Article
Purpose: To compare the visually weighted image quality and depth of focus achieved with small-pupil and multifocal strategies for expanding depth of focus of presbyopic or pseudophakic eyes. Setting: School of Optometry, Indiana University, Bloomington, USA. Design: Computational modeling. Methods: The visual Strehl ratio was computed from...
Conference Paper
Purpose: Aberrometry is a key tool for evaluating technological advances in eye care, e.g. wavefront-guided refractive surgery. However, the widely used high sampling density COAS HD aberrometer (Wavefront Sciences Inc.) is no longer available. We examined the accuracy and repeatability of a newly developed high sampling density (41μm lens diameter...

Children 8 and under on average spend 2.3h with screen media daily. The average time spent daily with mobile devices has tripled since 2013. Modern mobile devices are fully suited to measure illumination and near work distance in natural conditions at hight acquisition rates. We have developed a new mobile application, called VisionApp, capable of...

Purpose To develop an objective refraction formula based on the ocular wavefront error (WFE) expressed in terms of Zernike coefficients and pupil radius, which would be an accurate predictor of subjective spherical equivalent (SE) for different pupil sizes. Methods A sphere is fitted to the ocular wavefront at the center and at a variable distance...
Conference Paper
Full-text available
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...
Conference Paper

Purpose : To obtain fast and accurate measurements of the equivalent sphere (M) and amplitude of accommodation (AA; subjective SAA, objective OAA), taking into account the potential changes in refraction due to the changes of pupil size. Methods : An empirical wavefront refraction metric (MTR) was formulated using objective (OR) and subjective ref...
Article
Full-text available
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...

Purpose : To objectively evaluate the optical performance and simulate retinal images of an extended object in eyes wearing MPlus multifocal IOL's (Oculentis®), that offer an expanded depth of focus. To discover the reasons why some patients wearing those IOL's express discontent regarding their vision quality by using a novel computational method....
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....

IRIS (http://blogs.iu.edu/corl/iris) is a powerful and free app / program to conduct research in the fields of physiological optics / human vision / wavefront aberrometry / optometry. It can also be useful or interesting to students and teachers because of its intuitive graphical interface. Work with IRIS starts by inputting ocular aberrations espressed as Zernike coefficients using one of the supported data formats. Subsequently the following capabilities become available: - Computing optometric parameters: cylinder, sphere, axis, power vectors, minRMS, paraxial, MTR spherical equivalents, etc. - Performing both single and through-Zernike analyses of image quality (IQ), in particular through-focus analyses. - Computing Fourier and geometrical optics Point-Spread-Functions (PSFs). - Evaluating IQ with numerous objective refraction metrics. - Performing polychromatic simulations which take into account the longitudinal chromatic aberration (LCA), human spectral sensitivity curve (Vλ) and spectral power distribution (SPD) of a source. - Simulating effects of different pupil shapes and sizes and effects of pupil masking (for example due to cataract). - Computing and plotting detailed wavefront-derived functions such as vergence, curvature and slope and also the modulation transfer function (MTF).
