Evaluation of Corneal Irregular Astigmatism and Visual Quality Following Bilateral Sequential SMILE and LASEK: A Six‐Year Comparative Study

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Purpose To compare the corneal spherical component (SC), regular astigmatism (RA), irregular astigmatism (IA, including asymmetry and irregularity), and visual quality 6 years after small incision lenticule extraction (SMILE) and laser subepithelial keratomileusis (LASEK) for mild‐to‐moderate myopia.

Exploring the Impact of Refractive and Ocular Residual Astigmatism on Stereopsis After Photorefractive Keratectomy in Patients With Myopic Astigmatism

Journal of Ophthalmology, Volume 2026, Issue 1, 2026.
Background To investigate the impact of refractive and ocular residual astigmatism (ORA) on stereopsis after photorefractive keratectomy (PRK) for the correction of myopic astigmatism. Methods This prospective observational study was conducted on patients who underwent PRK for the treatment of myopia and myopic astigmatism using a Schwind Amaris 1050RS

Blue Light Defocus Induces A Positive Effect on Refractive Status and Ocular Health: A Randomized Crossover Trial

Global Challenges, Volume 9, Issue 12, December 2025.
This graphical abstract illustrates that varying degrees of intensity of defocus are associated with choroidal thickness, myopic defocus shift, and manifestations of visual fatigue, along with alterations in accommodation and convergence functions. Preliminary evidence suggests that blue light defocus technology could serve as a potential intervention ...

In‐community vision testing device development using a Kaupapa Māori framework

Kōtuitui: New Zealand Journal of Social Sciences Online, Volume 20, Issue 4, Page 1292-1302, December 2025.
ABSTRACT We report on a 2019 project in which we ran in‐community testing of a novel device for measuring visual acuity (the measure of performance obtained by an eye chart). This work was a collaboration with a community partner school, Kia Aroha College (KAC), a dual Māori/Pacific medium school in Ōtara, South Auckland, New Zealand.
