Excimer laser refractive surgery is a procedure performed worldwide to solve refractive errors and reduce dependence on glasses or contact lenses. There has been an increase in the number of procedures performed around the world. Myopia is the most common indication for corneal photorefractive surgery. Myopic patients have a higher risk of developing some type of glaucoma in their lifetime, such a...

Purpose: To report the rare case of a 29-year-old male with a history of keratoconus, who presented with a primary iris stromal cyst which eventually showed spontaneous regression.  Methods: Description of the clinical findings in the case of a 29-year-old male with a prior history of keratoconus, but no eye surgery or trauma, who consulted for an iris cyst in the left eye, diagnosed 9 months earl...

Aims: To describe the aetiology and microbial susceptibility profile of endophthalmitis cases treated at an ophthalmological referral centre in Colombia. Material and Methods: A retrospective descriptive study was carried out with all endophthalmitis cases referred to the Fundación Oftalmológica de Santander FOSCAL (Floridablanca, Colombia) from 1 January 2012 to 31 December 2015. Results: 121 eye...

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...

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 ...

Purpose: To describe clinical visual outcomes, spectacle independence, and patient satisfaction after cataract surgery with blending implantation of ReSTOR (Alcon laboratories) multifocal intraocular lenses. Material and Methods: A single-arm, non-randomized prospective study assessed patients undergoing cataract surgery with ReSTOR® +2.50 intraocular lens in the dominant eye and +3.00 add in the ...

Introduction: Spasm of the near reflex usually includes accommodative spasm, esophoria/tropia, and different degrees of miosis. Patients usually refer to distance blurred and fluctuating vision, ocular discomfort, and headaches. The diagnosis is established with refraction with and without cycloplegia; most of the cases have a functional etiology. However, some cases require neurological condition...

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...

Aim: To determine risk factors associated with keratoconus in Bucaramanga, Colombia. Material and Methods: A paired case-control study was conducted at Bucaramanga, Colombia, between November 2022 and December 2023. The controls were age- and sex-matched. Patients answered a questionnaire designed for this study regarding their family history of keratoconus, eye rubbing, atopy, sun exposure, and s...

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...
