The QuickSee autorefractor reliably measures the accommodative response in children compared with the Shin‐Nippon autorefractor

Ophthalmic and Physiological Optics, Volume 45, Issue 7, Page 1581-1590, November 2025.
Abstract Introduction This study evaluated the QuickSee autorefractor for measurement of the accommodative response in a cohort of children without significant ametropia, and compared the findings to those determined using the gold‐standard Shin‐Nippon device. Methods Children aged 5–7 years were recruited.

Evaluation of Corneal Aberrometry Parameters Before and After Cross-Linking in Patients with Keratoconus

پزشکی بالینی ابن سینا, 2023
Background and Objective: In the last decade, cross-linking (CXL) has been widely used for treating people with progressive keratoconus. The present study aimed to compare corneal aberrometry parameters before and after CXL in patients with keratoconus ...

Accuracy and precision of a sphero‐cylindrical over‐refraction app for smartphones

Ophthalmic and Physiological Optics, Volume 45, Issue 7, Page 1662-1675, November 2025.
Abstract Purpose To evaluate the accuracy and precision of a web‐based smartphone app designed to measure sphero‐cylindrical over‐refraction. Methods A total of 307 healthy young subjects (22.5 ± 3.4 years) underwent clinical subjective refraction. In addition to each subject's refractive correction, spherical and cylindrical errors from −1.50 to 0.00 ...

Impact of contact lens correction on wavefront aberrations and vision quality in keratoconus

Ophthalmic and Physiological Optics, Volume 45, Issue 7, Page 1811-1828, November 2025.
Abstract Purpose To review the optical principles of contact lens correction in keratoconus, with a focus on residual ocular wavefront error and its impact on vision performance. Findings Corneal rigid gas permeable (RGP) contact lenses, commonly used in keratoconus management, often fail to improve vision quality to levels observed in non‐diseased ...

Recommended practices for vision screening in pre‐school‐age children: A 2025 update

Optometry and Vision Science, Volume 102, Issue 10, Page 589-595, October 2025.
SIGNIFICANCE: Despite significant evidence supporting the utility of vision screening for identifying children who need further evaluation by an eye care professional, there is considerable variability in screening guidelines along with a lack of consensus for monitoring and reporting outcomes.

A comparison between subjective refraction and aberrometry-derived refraction in keratoconus patients and control subjects

, 2010
Purpose: This study compares the differences in the magnitude of the subjective refraction and three aberrometry-derived refractions along with visual acuity achieved with these refractions in a group of keratoconic patients and age-matched normal ...

Accommodative behaviour and retinal defocus of children during prolonged viewing of electronic devices while wearing dual‐focus myopia control soft contact lenses

Ophthalmic and Physiological Optics, Volume 45, Issue 6, Page 1456-1467, September 2025.
Abstract Purpose Chronic hyperopic defocus from inadequate accommodation during near tasks may be associated with axial eye growth. This study examined accommodative behaviour and retinal defocus in myopic and emmetropic children after 1 h of continuous electronic device use.
