Comparison of Intraoperative Parameters between Two Handpieces in One-Handed Phacoemulsification with Active Fluidics.

: To compare anterior chamber stability and surgical efficiency in one-handed phacoemulsification, comparing Ozil and Active Sentry (AS) handpieces. : Observational and comparative study. Selected patients were divided into two groups, AS and Ozil handpieces, and underwent one-handed phacoemulsification.

Modified "C" Haptic Intraocular Lens Orientation and Negative Dysphotopsia.

Phacoemulsification is the standard of care in cataract surgery in the developed world, with patients having high expectations regarding visual results. Postoperative dissatisfaction due to negative dysphotopsia (ND) ranges from rare to very frequent; its etiology is unclear, and it affects postoperative satisfaction. Since one of the most frequently used strategies to avoid ND is related to intraocular lens (IOL) haptic orientation, we conducted a prospective interventional study that enrolled 197 patients who underwent standard phacoemulsification.

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.

Is there any correlation between alpha-synuclein levels in tears and retinal layer thickness in Parkinson's disease?

Purpose: To determine the total alpha-synuclein (αSyn) reflex tears and its association with retinal layers thickness in Parkinson's disease (PD).

Methods: Fifty-two eyes of 26 PD subjects and 52 eyes of age-and sex-matched healthy controls were included. Total αSyn in reflex tears was quantified using a human total αSyn enzyme-linked immunosorbent assay (ELISA) kit.

Ultrabiomicroscopía ultrasónica y estabilidad de la lente intraocular en pacientes con miopía axial sometidos a cirugía de facoemulsificación.

Purpose: To evaluate the stability and the refractive error of the different intraocular lens (IOL) after cataract surgery.

Method: Retrospective, observational and single-center study. Patients diagnosed with cataract and myopia who underwent a phacoemulsification surgery with intraocular lens placement without complications were included.
