Methods: This is a prospective, comparative study performed at the Department of Ophthalmology, Goethe-University Frankfurt, Germany. Included were KC and healthy eyes.

Enhancing corneal ectasia susceptibility detection: analysis of a new algorithm (BAD-D v4).

Accurate detection of post-refractive ectasia susceptibility is essential during preoperative evaluation for laser vision correction (LVC) due to the risk of progressive corneal ectasia and vision decline post-surgery. Despite improved screening and a reduced incidence from 0.66 to 0.

Biomechanical Corneal Effects of LASIK-Xtra Compared to Conventional Femto-LASIK in High Myopic Eyes.

Purpose: This study seeks to investigate the in vivo corneal biomechanical response to femtosecond laser-assisted in situ keratomileusis (FS-LASIK) combined with accelerated corneal crosslinking (LASIK-Xtra) compared to conventional FS-LASIK (convLASIK) in highly myopic eyes.

Setting: Department of Ophthalmology, Goethe-University, Frankfurt, Germany.

Design: A prospective, randomized fellow eye-controlled clinical trial.

A comparison of cycloplegic effect of cyclopentolate 0.5% versus 1.0% eye drops with five different refraction measurement modalities in young adults.

Purpose: To compare the refraction before and after cycloplegia with 0.5% and 1.0% cyclopentolate eye drops using five different measurement modalities.

Carbon bursts inside a small aperture intraocular lens after Nd:YAG laser capsulotomy.

Purpose: The IC-8® Apthera™ (AcuFocus Inc.™, Irvine, California, USA) is the first small aperture intraocular lens (IOL) to receive FDA approval for presbyopia correction in the summer of 2022. It is a single-piece hydrophobic acrylic monofocal lens, which is placed in the capsular bag.

Repeatability and agreement of two ocular biometers with single and dual Scheimpflug cameras in keratoconus eyes.

Background: To evaluate the repeatability and agreement of two different ocular biometers and Scheimpflug devices in keratoconus eyes.

Methods: This prospective, comparative trial took place at the University hospital, Goethe University, Frankfurt am Main, Germany. We included eyes with keratoconus, one eye per patient, randomly selected.

Axial length adjustment in eyes with silicone oil endotamponade reduces overestimation by a swept-source optical coherence tomography-based biometer.

Background: To assess changes in ocular biometry of the phakic eye after pars-plana-vitrectomy (PPV) and silicone oil (SO) endotamponade in eyes with a retinal detachment.

Methods: This retrospective, consecutive case series included 72 eyes of 72 patients who underwent PPV with 5000-centistokes SO endotamponade between July 2018 and June 2023. Pseudophakic eyes and eyes with a combined phacovitrectomy were excluded.

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

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. Preoperative examinations included biometry (IOLMaster 700; Carl Zeiss).

IOL calculation using six formulas in children undergoing lens extraction and primary IOL implantation with and without posterior optic capture.

Purpose: To evaluate formulas for intraocular lens (IOL) calculation in children undergoing lens extraction and IOL implantation.

Methods: Retrospective, consecutive case series at the Department of Ophthalmology, Goethe University Frankfurt, Germany. We included eyes that received lens extraction and IOL implantation (SN60AT, Alcon, Fort Worth, TX) due to congenital or juvenile cataract.

Spherical equivalent prediction analysis in intraocular lens power calculations using Eyetemis: a comprehensive approach.

Purpose: To compare 2 different datasets, using Eyetemis, an online analytical tool designed for assessing the spherical equivalent prediction errors (SEQ-PEs) of intraocular lens (IOL) power calculation formulas after cataract surgery.

Setting: Institutional.

Design: Retrospective case series.

Blue Light Filtration in Intraocular Lenses: Effects on Visual Function and Systemic Health.

Blue light-filtering (BLF) intraocular lenses (IOLs) are designed to mimic the healthy natural adult crystalline lens. Studies that evaluated the relative merit of ultraviolet-only IOL design (ie, blocking wavelengths <400 nm) versus BLF IOL design (ie, filtering wavelengths ~400-475 nm in addition to blocking wavelengths <400 nm) on protection and function of the visual system suggest that neither design had a deleterious impact on visual acuity or contrast sensitivity. A BLF design may reduce some aspects of glare, such as veiling and photostress.

[ChatGPT and the German board examination for ophthalmology: an evaluation].

Purpose: In recent years artificial intelligence (AI), as a new segment of computer science, has also become increasingly more important in medicine. The aim of this project was to investigate whether the current version of ChatGPT (ChatGPT 4.0) is able to answer open questions that could be asked in the context of a German board examination in ophthalmology.
