Reading Performance Following Contralateral Implantation of an Extended Depth of Focus (EDOF) IOL and a Hybrid EDOF Multifocal IOL.

Purpose: To assess objective reading performance at intermediate and near distances using the Salzberg Reading Desk (SRD) (SRD Vision) in patients with cataract who underwent the implantation of a diffractive extended depth of focus intraocular lens (EDOF IOL) in the dominant eye and a hybrid multifocal EDOF IOL in the non-dominant eye.

Methods: This prospective, non-comparative, interventional study included 46 eyes of 23 patients with cataract who underwent bilateral cataract surgery with implantation of the DFR00V Tecnis Synergy IOL (Johnson & Johnson Surgical Vision) in the non-dominant eye and the DXR00V Tecnis Symfony OptiBlue IOL (Johnson & Johnson Surgical Vision) in the dominant eye. At postoperative 6 months, the Salzburg Reading Desk was used to assess distance-corrected reading performance at near and intermediate distances.

Prospective Evaluation of Clinical and Patient-Reported Outcomes Following Contralateral Implantation of an Extended Depth of Focus (EDOF) and Hybrid EDOF-Multifocal IOL.

Purpose: To evaluate clinical outcomes following contralateral implantation of a diffractive extended depth of focus (EDOF) and a hybrid EDOF-multifocal intraocular lens (IOL) with a violet filter in a U.S.-based population.

Prediction of the small aperture intraocular lens on visual acuity in patients with keratoconus.

Purpose: To investigate the impact of corneal higher-order aberrations (HOAs) on predicted corrected distance visual acuity (CDVA) in patients with keratoconus at varying simulated pupil apertures.

Setting: Ophthalmology Clinics, Medical University of South Carolina, Charleston, South Carolina.

Design: Retrospective chart review study.

Scheimpflug-Derived Corneal Lower and Higher Order Aberrations Post Intrastromal Corneal Ring Segments for Keratoconus.

Intrastromal corneal ring segments (ICRS) improve corneal topographic symmetry and reduce corneal aberrations through regularization of the corneal surface, thereby functioning as a viable surgical intervention for patients with keratoconus. This study aims to evaluate changes in lower- (LOAs) and higher-order aberrations (HOAs) amongst varying pupil sizes pre- and post- ICRS implantation in keratoconus patients. We specifically investigate the impact of pupil size on total corneal HOAs up to the 6th order.

Possible Sampling Error in Corneal Specular Microscopy: Can Central Endothelial Data Generated by Specular Microscope Represent the Real Clinical Condition of the Whole Cornea?

Purpose: To estimate the minimum number of cells required to obtain reliable data in a specular microscope, which could possibly represent the real clinical condition of the corneal endothelium.

Methods: A cross-sectional study of 122 eyes of 61 individuals submitted to noncontact specular microscope was conducted. Data generated by the manufacturer's software were uploaded to specific statistical software for sampling relative error calculation.
