Emmetropia Is Maintained Despite Continued Eye Growth From 16 to 18 Years of Age [PDF]

open access: yes, 2019
This work is licensed under a Creative Commons Attribution 4.0 International License.PURPOSE. To examine, in Norwegian adolescents, to what degree emmetropia and low hyperopia were maintained from 16 to 18 years of age, and if this was the case, whether ...

Effect of 0.025% atropine on ocular biometry changes during accommodation

open access: yesOphthalmic and Physiological Optics, Volume 45, Issue 3, Page 865-876, May 2025.
Abstract Purpose Low concentration atropine is an effective treatment to slow myopia progression and axial elongation and also reduces accommodation. On‐axis ocular dimensions of the eye change during accommodation; hence, this study aimed to quantify the effect of 0.025% atropine eye drops on accommodation‐induced changes in ocular biometry.

Refractive errors, ocular dimensions, and cone opsins in Norwegian adolescents [PDF]

open access: yes, 2020
The worldwide increase in myopia prevalence is of concern since the ocular elongation raises the risk of secondary ocular pathology. In order to establish effective myopia prevention strategies, a deeper knowledge of the mechanism underlying refractive ...

Prevalence of interocular symmetry in corneal astigmatism and the possible influence of age, sex and refractive error

open access: yesOphthalmic and Physiological Optics, Volume 45, Issue 2, Page 352-360, March 2025.
Abstract Purpose The aim of this study was to investigate, using a power vector approach, whether corneal astigmatism follows a mirror symmetry pattern considering both the magnitude and axis, and whether age, sex and spherical equivalent refractive error can influence the pattern.

Fellow eye data for intraocular lens calculation in eyes undergoing combined phacovitrectomy

open access: yesActa Ophthalmologica, Volume 103, Issue 1, Page e31-e37, February 2025.
Abstract Purpose To evaluate whether the intraocular lens (IOL) calculation of the fellow eye (FE) can be used in eyes undergoing combined phacovitrectomy. Methods In this retrospective, consecutive case series, we enrolled patients who underwent combined phacovitrectomy with silicone oil removal and IOL implantation at the Goethe‐University ...

Evaluation of keratometric and total corneal astigmatism measurements from optical biometers and anterior segment tomographers and mapping to reconstructed corneal astigmatism vector components [PDF]

open access: yes
Purpose To investigate different measures for corneal astigmatism in the context of reconstructed corneal astigmatism (recCP) as required to correct the pseudophakic eye, and to derive prediction models to map measured corneal astigmatism to recCP ...
