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

Optometry 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 ...

Prevalence and Associated Factors of Self‐Reported Myopia Among Undergraduate Students in the Northern Region of Bangladesh: A Cross‐Sectional Study

Health Science Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background and Aims Myopia is an increasingly important public health concern worldwide, particularly among young adults. While previous research has applied machine learning techniques to identify myopia‐related risk factors, evidence based on traditional statistical models using the same datasets remains limited. This study aimed to estimate

Early choroidal thickness changes predict myopia control response to peripheral defocus spectacles in premyopic children

Optometry and Vision Science, Volume 103, Issue 5, May 2026.
ABSTRACT Purpose To investigate whether early changes in choroidal thickness predict long‐term treatment response to peripheral defocus spectacles in premyopic children with insufficient hyperopic reserve. Methods Two hundred children aged 6–8 years with cycloplegic spherical equivalent refraction +0.25 to +0.75 diopters (D) and annual hyperopic ...

The longitudinal associations of reading, writing and screen time with myopia at age 9 years among children from the GUSTO birth cohort

Acta Ophthalmologica, Volume 104, Issue 3, Page e337-e345, May 2026.
Abstract Purpose To investigate the associations between paper‐based reading and writing time, screen‐based time at ages 2, 3, 6 and 9 years and myopia at age 9 in the GUSTO birth cohort. Methods The GUSTO study recruited pregnant women from two Singapore public maternity hospitals between 2009 and 2010. Parent‐reported reading and writing time, screen

The Effect of Myopic Optical Defocus on the Humphrey Matrix 30-2 Test

Journal of the Korean Ophthalmological Society, 2008
Purpose: To investigate the effect of myopic optical defocus on Humphrey Matrix 30-2 test. Methods: Twenty-nine myopic eyes of 29 patients underwent 2 consecutive tests with the Humphrey Matrix 30-2 threshold program. The first and second tests were performed with and without correction for myopia.

Exploring the role of low‐dose atropine in myopia management in children with inherited retinal diseases

Optometry and Vision Science, Volume 103, Issue 4, April 2026.
ABSTRACT Purpose This study aimed to evaluate the effectiveness of low‐dose atropine in slowing myopic progression in children with inherited retinal diseases (IRDs) and myopia. Methods Retrospective study of children with IRDs, comparing myopia progression between those who received atropine drops and those who did not was conducted.

Measurement of the point-spread function of a noisy imaging system [PDF]

, 2007
The averaged point-spread function (PSF) estimation of an image acquisition system is important for many computer vision applications, including edge detection and depth from defocus. The paper compares several mathematical models of the PSF and presents

A review of angle kappa and multifocal intraocular lenses and their effect on visual outcomes

Acta Ophthalmologica, Volume 104, Issue 2, Page e122-e138, March 2026.
Abstract Although most patients are satisfied with their vision after multifocal intraocular lens (IOL) implantation, dissatisfaction has been reported for various reasons, including poor visual outcomes and visual disturbances. Many published reports hypothesise that preoperative angle kappa may be an associated factor in patient dissatisfaction ...
