Accuracy of Astigmatism Calculation with the Barrett, Panacea, and enVista Toric Calculators.

Purpose: To evaluate residual refractive astigmatism using the Panacea and enVista toric calculators, compared to the gold-standard Barrett toric calculator.

Design: A retrospective and comparative study was conducted in one center.

Methods: We reviewed the medical records of all patients with a diagnosis of senile cataracts and regular corneal astigmatism, without previous corneal or intraocular surgery, who underwent phacoemulsification with implantation of a toric intraocular lens, who had pre- and postoperative corneal topography, biometry, and refraction measurements.

Magnification and Refocusing Comparison in Cataract Surgery Using a Heads-Up Three-Dimensional Visualization System versus Conventional Binocular Microscopy.

Purpose: To compare magnification and refocusing during phacoemulsification with the NGENUITY 3-D Visualization System (3-D) versus the conventional microscope (CM) OPMI LUMERA 700.

Setting: This study was performed in the Department of Anterior Segment of the Fundación Hospital Nuestra Señora de la Luz.

Design: Prospective, randomized, cross-sectional, multi-surgeon, and comparative study.

Relationship between Helicobacter pylori and undifferentiated non-granulomatous anterior uveitis.

Purpose: The relationship of Helicobacter pylori infection with ocular diseases, including anterior uveitis, has been reported. The objective of this study was to determine the presence of anti-H. pylori IgG antibodies in patients with idiopathic non-granulomatous anterior uveitis and compare the results with a control group.
