Agreement in anterior segment measurements between swept-source and Scheimpflug-based optical biometries in keratoconic eyes: a pilot study

Therapeutic Advances in Ophthalmology, 2022
Background: Cataract surgery in keratoconic patients is challenging because of the corneal distortion, which can lead to inaccurate keratometry readings.

Identification of a Novel Splice‐Site Variant in CACNA1F With Variable Phenotypic Expression in a Chinese Family

Molecular Genetics &Genomic Medicine, Volume 13, Issue 12, December 2025.
A novel splice‐site variant (NM_005183.4:c.4422‐1G>T) in CACNA1F with familial expression variability was identified, providing new genotypic and phenotypic information on CACNA1F‐related retinal disorders. ABSTRACT Background The calcium voltage‐gated channel subunit alpha1 F (CACNA1F) gene‐related retinal disorders have overlapping clinical symptoms ...

Defocus Incorporated Multiple Segments (DIMS) spectacle lenses in UK children: Outcomes from a 2‐year multi‐site interventional trial

Ophthalmic and Physiological Optics, Volume 45, Issue 7, Page 1965-1980, November 2025.
Abstract Introduction Myopia is a growing public health concern with long‐term risks for visual impairment. While Defocus Incorporated Multiple Segments (DIMS) spectacle lenses have proven efficacy in Chinese children, evidence from Western populations remains limited.

Jackknife and bootstrapping resampling techniques to evaluate the precision of lens formula constants

Acta Ophthalmologica, Volume 103, Issue 6, Page e422-e433, September 2025.
Abstract Purpose The purpose of this study was to develop a method for evaluating intraocular lens (IOL) formula constant uncertainties using two modern statistical techniques—jackknife and bootstrap resampling. Methods Using two datasets (dataset 1: 888 eyes treated with the aberration correcting Hoya Vivinex IOL, dataset 2: 821 eyes with the ...
