Determination of Factors Associated With Long-Term Endothelial Loss and Refractive Result in Patients With Artisan Phakic Lens Journal > /en/journal/2022/4/4
Purpose: To determine the changes in endothelial cell density, refractive results, and risk factors associated with endothelial loss in patients with iris-claw phakic intraocular lenses for myopia/myopic astigmatism (Artisan). Methodology: Data collection was obtained from an existing database with information on patients with a phakic Artisan lens implant between 1998 and 2011 at the Virgilio Gal...
Determination of Corneal Power After Refractive Surgery with Excimer Laser: A Concise Review Journal > /en/journal/2023/5/1
Refractive surgery with excimer laser has been a very common surgical procedure worldwide during the last decades. Currently, patients who underwent refractive surgery years ago are older, with a growing number of them now needing cataract surgery. To establish the power of the intraocular lens to be implanted in these patients, it is essential to define the true corneal power. However, since the ...
Clinical History Method versus Corneal Tomographers in Estimating Corneal Power after Photorefractive Surgery Journal > /en/journal/2025/2/3
Aims: To investigate the concordance between the corneal power determined by various approaches with two tomographers (MS-39® and Galilei G6®) and the clinical history method (CHM) in patients undergoing photorefractive surgery with excimer laser for myopic errors. Material and Methods: Prospective cohort study. Patients undergoing keratorefractive surgery, and having pre- and postoperative kerato...
Sleeping Behavior and Keratoconus: A Scoping Review Journal > /en/journal/2025/3/1
Aims: This scoping review was conducted to investigate whether nocturnal eye compression from inappropriate sleeping postures may contribute to the development or asymmetry of keratoconus (KC), by examining the association between sleeping positions and KC. Material and Methods: A systematic search of CENTRAL, MEDLINE, EMBASE, LILACS, ClinicalTrials.gov, gray literature, and selected journals from...
Presentation of a New Method for Quantitative Determination of Trifocal Intraocular Lens Decentration Journal > /en/journal/2025/5/5
Aims: This pilot study aims to present a novel method for quantitatively assessing the decentration of a trifocal intraocular lens (IOL) (Acrysof IQ PanOptix®) relative to three ocular reference points: the visual axis (first Purkinje reflex), the photopic pupil center, and, for the first time, the corneal geometric center. Additionally, the study evaluates the influence of postoperative chord mu,...
