Comparison of biometric measurements taken with IOL Master 500 and Pentacam AXL for ocular biometry

Rev. cuba. oftalmol; 34 (1), 2021
Objetivo: Comparar las mediciones biométricas realizadas con el IOL Master 500 y el Pentacam AXL. Métodos: Se realizó un estudio transversal en 99 ojos de 99 pacientes miopes con criterio de cirugía fotoablativa, atendidos en el período de enero del año 2019 a enero de 2020, en el Servicio de Ciru...

Effects of pupillary dilation on ocular optical biometry outcomes in pediatric patients

Arq. bras. oftalmol; 83 (4), 2020
ABSTRACT Purpose: Pharmacological pupillary dilation is performed in comprehensive ophthalmological examinations and before biometric measurements. So far, there is no consensus regarding its impact on biometric measurements. This study's aim was to investigate the effects of pharmacological pupillary d...

Comparing the postoperative refractive predictability of Pentacam HR and IOLMaster 500 after a multifocal intraocular lens implantation

Arq. bras. oftalmol; 83 (2), 2020
ABSTRACT Purpose: To compare the postoperative refractive predictability of IOLMaster 500 and Pentacam HR on the basis of keratometry and anterior chamber depth values in eyes with an indication for multifocal intraocular lens (IOL) implantation. Methods: This was a retrospective study conducted on 118...

Anterior chamber characteristics assessed by rotating Scheimpflug imaging in patients with retinitis pigmentosa

Arq. bras. oftalmol; 82 (6), 2019
ABSTRACT Purpose: The aim of this study was to evaluate anterior segment parameters and corneal aberrations in patients with retinitis pigmentosa using Scheimpflug imaging and to compare the findings with those for healthy controls. Methods: This single-center, case-control study included patients diag...

Analysis between two optical biometric devices in patients with cataract

Rev. bras. oftalmol; 77 (4), 2018
ABSTRACT Objective: To evaluate the correlation of optical biometry and target with variable ages, anterior chamber depth, axial length, R1/K1 and R2/K2 established by two optical biometry devices in patients with cataract. Methods: The study included the analysis of 348 medical records, from which 503 c...

Ultrasound biomicroscopy in acetazolamide-induced myopic shift with appositional angle closure

Arq. bras. oftalmol; 80 (5), 2017
ABSTRACT We report a case of a 49-year-old female who presented to the emergency department with blurred vision and vomiting, hours after taking two tablets of 250 mg of acetazolamide. The anterior chamber was bilaterally flat, with normal intraocular pressure in both eyes. An ultrasound biomicroscopic (...

Evaluation of anterior segment parameters using Scheimpflug technology during the Valsalva maneuver in patients with keratoconus

Arq. bras. oftalmol; 79 (6), 2016
ABSTRACT Purpose: This study aimed to explore the effects of the Valsalva maneuver (VM) on ectatic corneas during anterior segment tomography scans using a Scheimpflug camera. Methods: This prospective observational study included 100 eyes of 50 patients with bilateral keratoconus (KC). Anterior segmen...
