Long-Term Outcomes of 10-Minute Accelerated Corneal Cross-Linking on Structural, Topographic, and Tomographic Corneal Parameters: A 5-Year Prospective Study

Journal of Current Ophthalmology
Purpose: To evaluate the long-term effects of accelerated corneal cross-linking (ACXL) in stabilizing progressive keratoconus (KC), as these effects remain unclear.

Corneal power modelling with OCT data – Thin and thick lens paraxial models versus raytracing

Acta Ophthalmologica, EarlyView.
Abstract Background Evaluating keratometric power with Zeiss index (PKZ), paraxial thick cornea power (Gullstrand [PG]) and power referenced to the front (PFV) and back vertex plane (PBV) and raytracing power (PR), and modelling the deviation from PKZ with a multivariable linear prediction model.

Repeatability of Corneal Elevation Maps in Keratoconus Patients Using the Tomography Matching Method [PDF]

, 2017
To assess repeatability of corneal tomography in successive measurements by Pentacam in keratoconus (KC) and normal eyes based on the Iterative Closest Point (ICP) algorithm. The study involved 143 keratoconic and 143 matched normal eyes.

Multi‐site performance of the telemedicine retinopathy of prematurity severity score (tROP‐SS)

Acta Ophthalmologica, EarlyView.
Abstract Objective This study aims to evaluate the performance of the telemedicine retinopathy of prematurity severity score (tROP‐SS) across all 14 NICUs in the TELEROP cohort against the modified ROP activity score (mROP‐ActS). Design Retrospective cohort study. Subjects The study included 2037 neonates who underwent ROP screening in 14 NICUs via the

Repeatability of keratometry depending on tear film osmolarity

Acta Ophthalmologica, EarlyView.
Abstract Purpose To determine the repeatability of keratometry and astigmatism measurements of patients depending on the tear film osmolarity using three different devices. Methods In this study, 97 eyes of 97 patients with a mean age of 64.92 ± 12.07 years received three repeated measurements with the IOLMaster 700 (Carl Zeiss Meditec, Jena, Germany),

An adaptive algorithm for the cornea modeling from keratometric data [PDF]

, 2010
In this paper we describe an adaptive and multi-scale algorithm for the parsimonious t of the corneal surface data that allows to adapt the number of functions used in the reconstruction to the conditions of each cornea.

The hidden science of haptics: A pedagogical review of tactile evaluation in cosmetics

International Journal of Cosmetic Science, EarlyView.
This review explores the physiological basis of tactile perception and critically examines classical and emerging sensory methods used in cosmetics, advocating for broader methodological integration and recognition of sensory analysis in the field. Abstract Sensory analysis is a cornerstone of cosmetic development, yet remains underrepresented in peer ...
