Comparing dislocation force between a flanged haptics IOL and a harpoon haptics IOL.

To compare two different secondary IOL fixation techniques, either flanged or hooked, regarding the least required force to dislocate the haptic in human corneoscleral donor tissue (CST). Experimental laboratory investigation. The least required dislocation force (LRDF) of two different fixation techniques, namely the flanged haptics (FH, as described by Yamane) and the harpoon haptic technique (HH, as described by Carlevale) were investigated using 20 three-piece IOLs (KOWA PU6AS) and 20 single-piece IOLs (SOLEKO CARLEVALE) fixated to human scleral tissue.

Update on intraocular lens formulas.

Purpose Of Review: This review aims to discuss recent advances in intraocular lens (IOL) power calculation, including newly introduced formulas, classification updates, comparative analyses between formulas, and emerging trends in the field.

Recent Findings: A significant number of modern IOL power calculation formulas have become available, incorporating both established and novel concepts such as artificial intelligence and ray tracing. A revised classification system has been introduced, reflecting the underlying principles of each formula.

Sustainable practices in ophthalmology-steps towards environmental stewardship in healthcare.

The healthcare sector, responsible for approximately 4-5% of global carbon dioxide equivalent (COeq) emissions, significantly impacts the environment due to its high energy consumption and waste generation. As a specialty, ophthalmology has a disproportionately large environmental impact because of the high annual volume of ophthalmic surgeries. In recent years, significant organized efforts have focused on reducing ophthalmology's carbon footprint while maintaining quality patient care.

Comparing an Advanced Monofocal With a Non-diffractive Extended Depth of Focus Intraocular Lens Using a Mini-Monovision Approach.

Purpose: To compare interindividual differences in visual performance of an advanced monofocal with a nondiffractive extended depth of focus intraocular lens (IOL) using a mini-monovision approach.

Design: Single-center, randomized, controlled, double-masked study.

Methods: In total, 48 patients (96 eyes) with bilateral age-related cataract were enrolled.

Changes of Optical Coherence Tomography Biomarkers after Peeling of Epiretinal Membranes.

Introduction: Several optical coherence tomography (OCT) biomarkers for postsurgical success among patients with idiopathic epiretinal membranes (iERMs) undergoing pars plana vitrectomy and membrane peeling have been described in the past. The aim of this study was to examine the remission of OCT biomarkers in patients with iERM after pars plana vitrectomy with membrane peeling 3 months and 1 year after surgery.

Methods: This prospective study included patients scheduled for pars plana vitrectomy with membrane peeling for iERM.
