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 ...

Deciphering the performance of different surface models for corneal topography

Ophthalmic and Physiological Optics, Volume 45, Issue 6, Page 1270-1281, September 2025.
Abstract Purpose To study the performance of different corneal surface models to be used for ray tracing. Models based on geometric surfaces and polynomial fits were compared and the differences discussed. Methods For this simulation study, five characteristic generic surface configurations were generated: (A) perfect biconic, (B) decentred biconic ...

Parental Mosaicism in PAX6 Causes Intra-Familial Variability: Implications for Genetic Counseling of Congenital Aniridia and Microphthalmia

Frontiers in Genetics, 2018
Mutations in PAX6 are involved in several developmental eye disorders. These disorders have considerable phenotypic variability, ranging from panocular forms of congenital aniridia and microphthalmia to isolated anomalies of the anterior or posterior ...

Integrative snRNA‐seq, molecular docking and dynamics simulations identifies Lasmiditan as drug candidate for Alzheimer's disease

Clinical and Translational Medicine, Volume 15, Issue 8, August 2025.
Multi‐cohort snRNA‐seq analysis identified 20 key transcriptional regulators in Alzheimer's disease (AD). Lasmiditan was the top drug identified for repurposing as it showed strong binding stability with ETV6 and favourable blood–brain barrier permeability.
