open‐field autorefractionPurpose: To compare refractive values measured with and without cycloplegia, or with fogging lenses, using an open-field auto-refractor. Methods: One hundred and forty-two young adults were enrolled from a university population; 96 were female (67.6%) and 46 were male ...
The WMT-1 is a new device that is connected to the WAM-5500 open-field autorefractor. It can move a target optionally from 0.2 to 1.0 meter and measure refraction every 0.2 second. We made shape of the cross as a visual target, displayed it in iPad (Apple Inc., Cupertino, CA). We...
Evaluation of an open-field autorefractor's ability to measure refraction and hence potential to assess objective accommodation in pseudophakes. Br J Ophthalmol 2011; 95:498-501Wolffsohn JS, Davies LN, Naroo SA et al. Evaluation of an open-field autorefractor's ability to measure refraction ...
A prospective, repeatability and accuracy study was accomplished on a slit-scanning ophthalmoscope and an open-field autorefractor. Methods :Cycloplegic refraction was measured along the horizontal meridian at 10掳, 20掳, and 30掳 temporally/nasally in 6 subjects (6 eyes) with a distribution of ...
Purpose: To evaluate the usefulness of an infrared open-field autorefractor as a predictor of the refractive error when fitting multifocal contact lenses (MCL).Giner, AnnaAldaba, MikelArjona, MonserratVilaseca, MeritxellPujol, JaumeContact lens & anterior eye: the journal of the British Contact ...
To evaluate the usefulness of an infrared open-field autorefractor as a predictor of the refractive error when fitting multifocal contact lenses (MCL). Objective and subjective measurements of the non-cycloplegic distance refractive error were compared in patients wearing MCL. We used the Grand ...
Suitability of open-field autorefractors as pupillometers and instrument design effects 学生重覆性同意田野AIM:To determine the agreement and repeatability of the pupil measurement obtained with VIP-200(Neuroptics),Power Ref II(Plusoptix),WAM-5500(Grand Seiko) and study the effects of instrument ...
Purpose : High repeatability portable autorefractors may enable effective deploy of global-health initiatives to mitigate uncorrected refractive error worldwide. For example, in studies to evaluate the effectiveness of different measures, repeatability has a direct impact on the statistical power and ...
Purpose : To evaluate the agreement and repeatability between a binocular open-field wavefront autorefractor, as part of Eye Refract dynamic refraction system, (BOWA) and a monocular closed-field wavefront autorefractor (MSWA). Methods : A cross-sectional, randomized and single-masked study was ...
