A randomized crossover clinical trial of the Deseyne contact lens for presbyopia with extended depth of focus

open access: yesOptometry and Vision Science, Volume 103, Issue 6, June 2026.
ABSTRACT Purpose To evaluate the visual performance of a new daily wear presbyopia contact lens (Deseyne contact lens for presbyopia with extended depth of focus). Methods This was a randomized, crossover, and nondispensing clinical trial. Seventy‐eight presbyopic (45–70 years, mean = 53.9 years) habitual soft contact lens wearers were recruited with ...

Advances in the genetics of refractive errors: Contributions from the CREAM consortium

open access: yesActa Ophthalmologica, Volume 104, Issue 3, Page e222-e231, May 2026.
Abstract The Consortium for Refractive Error and Myopia (CREAM) was established in 2011, bringing together an international team of researchers studying more than 30 cohorts. Since its establishment, CREAM has played a pivotal role in research investigating the genetics of myopia and other refractive errors, serving as a key driver of progress in the ...

The Relation Between Corneal and Total Astigmatism

open access: yes, 1996
Using computer-assisted videokeratoscopy we measured corneal astigmatism and compared these results over a range of corneal zone diameters with total ocular astigmatism derived by subjective refraction.

Managing Corneal Astigmatism

open access: yesUP Journal of Ophthalmology, 2023
Corneal astigmatism is a refractive error that creates an asymmetric blur in the vision. Corneal astigmatism can arise from trauma, disease, following surgery, or be congenital. In assessing corneal astigmatism, a decision should be made as to whether the astigmatic pattern is regular or irregular.

Haplotype‐Based Analysis of OCA2 Variants in Oculocutaneous Albinism

open access: yesPigment Cell &Melanoma Research, Volume 39, Issue 3, May 2026.
This study defines multi‐allele haplotypes, comprised of rare disease variants combined with common eQTL, sQTL and GWAS variants, for oculocutaneous albinism type 2 (OCA2). These haplotypes have implications for variant pathogenicity assessments and phenotypic variability.
