Fuchs' Endothelial Corneal Dystrophy evaluation using a high-resolution wavefront sensor.

This study aims to evaluate the applicability of the high-resolution WaveFront Phase Imaging Sensor (WFPI) in eyes with Fuchs' Endothelial Corneal Dystrophy (FECD) through qualitative and quantitative analysis using a custom-designed Automatic Guttae Detection Method (AGDM). The ocular phase was measured using the t eyede aberrometer and then was processed to obtain its High-Pass Filter Map (HPFM). The subjects were pathological and healthy patients from the Fundación Jiménez-Díaz Hospital (Madrid, Spain).

Comparing the clinical applicability of wavefront phase imaging in keratoconus versus normal eyes.

The aim of this work is to quantitatively assess the wavefront phase of keratoconic eyes measured by the ocular aberrometer t·eyede (based on WaveFront Phase Imaging Sensor), characterized by a lateral resolution of 8.6 µm without requiring any optical element to sample the wavefront information. We evaluated the parameters: root mean square error, Peak-to-Valley, and amplitude of the predominant frequency (Fourier Transform analysis) of a section of the High-Pass filter map in keratoconic and healthy cohorts.

Efficacy, safety and cost-effectiveness of 5-fluorouracil versus interferon α-2b as adjuvant therapy after surgery in ocular surface squamous neoplasia in a southern European tertiary hospital.

Purpose: To analyze the efficacy, safety and cost-effectiveness of adjuvant therapy with 5-fluorouracil (5-FU) compared to interferon α-2b (IFNα-2b) after surgery in ocular surface squamous neoplasia (OSSN).

Methods: Retrospective study that included patients diagnosed with OSSN, who underwent surgical excision followed by adjuvant therapy with IFN α-2b (Group A) or 5-FU (Group B), in a tertial referral hospital. Clinical data collected included: demographics, risk factors, appearance, size and location of the lesions, slit-lamp examination, anterior segment optical coherence tomography, iconography and histological classification of subtypes of OSSN.

Ametropia detection using a novel, compact wavefront autorefractor.

Introduction: Despite the well-known reproducibility issues of subjective refraction, most studies evaluating autorefractors compared differences between the device and subjective refraction. This work evaluated the performance of a novel handheld Hartmann-Shack-based autorefractor using an alternative protocol, which considered the inherent variability of subjective refraction.

Methods: Participants underwent an initial measurement with a desktop autorefractor, two subjective refractions (SR1 and SR2) and a final measurement with the QuickSee Free (QSFree) portable autorefractor.
