Differentiation Between Pellucid-Like Keratoconus and Pellucid Marginal Degeneration Using Swept-Source Optical Coherence Tomography.

Purpose: The distinction between pellucid-like keratoconus (PLK) and pellucid marginal corneal degeneration (PMD) based on tomographic examinations is difficult. In this study, corneal tomographic and biomechanical parameters, after classifying PMD and PLK using swept-source optical coherence tomography, were analyzed.

Methods: Diagnoses of PLK and PMD were made using SS-OCT imaging, two groups were formed: PLK (n = 30) and PMD (n = 10).

Effectiveness and safety of VISULAS® green selective laser trabeculoplasty: 12 months retrospective data.

To report the safety and effectiveness of selective laser trabeculoplasty (SLT) using the SLT mode of the VISULAS green laser in patients with primary open-angle glaucoma (POAG). Twelve months results are presented. Retrospective extension in 4 German centers of an initially prospective interventional multicenter 3-month clinical investigation using the VISULAS green SLT (Carl Zeiss Meditec AG, Jena, Germany) in patients with POAG who either needed treatment escalation or commenced treatment and had an IOP ≥ 17mmHg at baseline, with no previous glaucoma or other ocular surgery.

Evaluation of indices for the assessment and classification of keratoconus based on optical coherence tomography and Scheimpflug technology.

Purpose: To compare the parameters and indices of a novel swept-source optical coherence tomography device (SS-OCT, ANTERION) with those of a rotating Scheimpflug camera (RSC)-based tomograph (Pentacam) in normal and keratoconic (KC) eyes.

Methods: This prospective, monocentric, cross-sectional study included individuals with unoperated normal and KC eyes, selecting one eye per subject. Ectasia-specific parameters analysed with the SS-OCT were difference in mean keratometry (K) in the inferior and superior meridians, maximum keratometry value (K), elevation of the posterior surface at the thinnest point, screening corneal objective risk of ectasia (SCORE) and thinnest point thickness.

The Increase in Corneal Stiffness After Accelerated Corneal Cross-Linking in Progressive Keratoconus Using Different Methods of Epithelial Debridement.

Purpose: The purpose of this study was to investigate corneal stiffening after epithelium-off accelerated corneal cross-linking (CXL; 9 mW/cm²) in progressive keratoconus (KC) with different methods of epithelial debridement.

Methods: This was a retrospective, interventional, and non-randomized study. In group 1, the epithelium was removed using a hockey knife (N = 45).

Early Results of Preserflo MicroShunt for Primary Open Angle Glaucoma in White Patients.

Prcis: The Preserflo MicroShunt effectively lowered intraocular pressure in primary high and normal pressure open angle glaucoma.

Purpose: To evaluate the efficacy and safety of the Preserflo MicroShunt in patients with primary open angle glaucoma (POAG) and the 2 variants high (HPG) and normal pressure glaucoma (NPG) after 1 year.

Methods: Single-center prospective interventional case series consecutively including eyes of White/European patients with POAG, who received the Preserflo MicroShunt as a primary and standalone glaucoma intervention.
