Regional corneal biomechanics assessment as a function of age using Strain–Stress Index maps

Ophthalmic and Physiological Optics, Volume 45, Issue 7, Page 1773-1779, November 2025.
Abstract Purpose To gain a better understanding of corneal Stress–Strain Index (SSI) maps in healthy eyes and to determine their changes with age. Method The eyes of 72 participants (age 43.1 ± 20.9 years, 69.5% female) were included in the analysis, considering the left and right eyes separately.

Normative Values on Stromal Curvature, Power and Corneal‐Stromal Curvature Ratios From a Hybrid AS‐OCT

Clinical &Experimental Ophthalmology, Volume 53, Issue 7, Page 746-755, September/October 2025.
ABSTRACT Background To establish normative values for stromal curvature and its relationships to anterior and posterior curvature. Methods Retrospective observational study. Data were obtained from 75 eyes of cataract surgery patients using a high‐resolution anterior segment optical coherence tomograph (AS‐OCT; MS‐39, CSO).

Axial elongation as a marker to identify obvious myopic shift in non‐myopic eyes of Chinese children

Ophthalmic and Physiological Optics, Volume 45, Issue 6, Page 1435-1446, September 2025.
Abstract Purpose Rapid axial elongation in emmetropic eyes may indicate an increased risk of myopia onset. This study aimed to examine the range of axial elongation in non‐myopic eyes, to distinguish between those with and without an obvious myopic shift and establish criteria to predict myopia onset within 1 year.

Estimation of final cylindrical spectacle correction by Pentacam

Function and Disability Journal, 2020
Background and Objectives: Keratoconus is a non-inflammatory asymmetric corneal degenerative disease characterized by the steepening and distortion of the cornea. In this disease, irregular astigmatism makes the subjective refraction difficult. Using the

Extremely asymmetric ectasia: Tomographically unilateral keratoconus

Acta Ophthalmologica, Volume 103, Issue 5, Page 530-538, August 2025.
Abstract Purpose To investigate the characteristics of apparently stable forms of tomographically unilateral keratoconus (KC). Methods In this retrospective case–control study, strict unilaterality criteria were applied to select tomographically unilateral cases with ≥3 years of follow‐up.

Influence of artificial tears on corneal parameter measurement using three different devices: Keratometry and Scheimpflug technology, a randomized trial

Acta Ophthalmologica, Volume 103, Issue 5, Page e310-e317, August 2025.
Abstract Purpose To evaluate the effect of artificial tear (AT) application on the repeatability of corneal parameters with three different devices. Methods In this prospective, randomized clinical trial, 145 patients were measured with one of three devices in the Department of Ophthalmology, Goethe University, Frankfurt, Germany.

Cataract Surgery in the Small Adult Eye: A Review

Clinical &Experimental Ophthalmology, Volume 53, Issue 5, Page 558-569, July 2025.
ABSTRACT Modern cataract surgery continues to advance, yet intraocular lens (IOL) based surgery in the small adult eye remains challenging. Thorough preoperative assessment and surgical preparation optimise postoperative outcomes in these cases. Advances in IOL power calculation, including artificial intelligence‐driven formulas, improve accuracy ...
