Retrospective Analysis of a Clinical Algorithm for Managing Childhood Myopia Progression

Optometry and Vision Science, Volume 100, Issue 1, Page 117-124, January 2023., 2023
ABSTRACT SIGNIFICANCE As the myopia epidemic unfolds, there is growing urgency to identify and implement effective interventions to slow myopia progression. This investigation evaluated the effectiveness of an evidence‐based myopia treatment algorithm in a clinical setting among 342 consecutive children.

Development and Verification of an Adjustment Factor for Determining the Axial Length Using Optical Biometry in Silicone Oil-Filled Eyes

Diagnostics, 2022
The aim of this prospective clinical study was to establish and verify an adaptation for axial length (AL) measurement in silicone oil (SO)-filled pseudophakic eyes with a Scheimpflug and partial coherence interferometry (PCI)-based biometer.

Wavefront aberrations in aging measured with Hartmann-Shack at 3- and 5-mm pupil sizes. [PDF]

Optom Vis Sci
SIGNIFICANCE Visual acuity (VA) depends on many factors. When the goal is to assess retinal health rather than performance, then using a 3‐mm pupil reduces unwanted wavefront aberrations. The axis of astigmatism can still potentially change with age.

Prediction of ocular magnification and aniseikonia after cataract surgery

Acta Ophthalmologica, Volume 100, Issue 8, Page e1675-e1684, December 2022., 2022
Abstract Background Ocular magnification and aniseikonia after cataract surgery has been widely ignored in modern cataract surgery. The purpose of this study was to analyse ocular magnification and inter‐individual differences in a normal cataract population with a focus on monovision.

Split‐Window OCT biometry in pseudophakic eyes

Acta Ophthalmologica, Volume 100, Issue 8, Page e1685-e1690, December 2022., 2022
Abstract Purpose To determine the utility of Split‐Window optical coherence tomography OCT (SW‐OCT) biometry in measuring ocular axial dimensions as well as imaging the intraocular lens (IOL) and posterior capsule in pseudophakic eyes. Methods Sixty‐nine pseudophakic eyes of 69 subjects were enrolled in the study.

[Retracted] Effect of Atropine Eye Drops Combined with VR‐Based Binocular Visual Function Balance Training for Prevention and Control of Juvenile Myopia

Evidence-Based Complementary and Alternative Medicine, Volume 2022, Issue 1, 2022., 2022
Purpose. This study mainly analyzes the efficacy of 0.01% atropine eye drops (low‐dose atropine (LDA)) combined with virtual reality (VR)‐based binocular visual function (BVF) balance training in the prevention and control of juvenile myopia. Methods.

The Pentacam® AXL Wave provides a reliable wavefront-based objective refraction when compared to manifest subjective refraction: A prospective study

Indian Journal of Ophthalmology, 2022
Purpose: Accurate refraction is arguably the most important parameter for a successful laser vision correction surgery and is based on a combination of manifest and cycloplegic refraction.

Simultaneous Corneal Topography and Epithelial Thickness Mapping from a Single Measurement Using Optical Coherence Tomography

Journal of Ophthalmology, Volume 2022, Issue 1, 2022., 2022
Purpose. To evaluate the performance of corneal epithelial thickness mapping (ETM) and demonstrate simultaneous measurement of ETMs and corneal topography using REVO NX (Optopol Technology, Zawiercie, Poland)—an OCT device for anterior and posterior segment imaging. Methods. One hundred thirty‐seven eyes of 137 normal subjects and patients with corneal

Effect of Implantable Collamer Lens on Anterior Segment Measurement and Intraocular Lens Power Calculation Based on IOLMaster 700 and Sirius

Journal of Ophthalmology, Volume 2021, Issue 1, 2021., 2021
Purpose. To investigate the possible effect of an implantable collamer lens (ICL) on ocular biometrics and intraocular lens (IOL) power calculation. Methods. Ocular measurements were taken preoperatively and at the two‐month follow‐up using IOLMaster 700 and Sirius in 85 eyes (43 patients) who had previously undergone ICL surgery.

Relationship between Medium-Term Changes in Intraocular Lens Position and Refraction after Cataract Surgery with Two Different Models of Monofocal Lenses [PDF]

, 2021
The aim of this prospective descriptive study was to characterize the variations of the clinical effective lens position (ELP) (considering paraxial optics and postoperative data) and the intraocular lens (IOL) position, using “eye” data gathered from a ...
