Validation of Clinical Protocol of Astigmatism Induction in Pseudophakic Patients.

Purpose: Validate a novel approach for assessing residual astigmatism's impact on visual acuity in pseudophakic patients using defocus curves and spherical equivalent compensation.

Materials And Methods: Thirteen patients over 40 with cataracts and normal ophthalmological examinations were enrolled in a prospective, non-randomized cohort study. The defocus curve method was employed, wherein visual acuity was measured with spherical lenses ranging from -2.

A New Methodology for Evaluating the Potential Impact of Residual Refractive Astigmatism in Pseudophakic Patients.

Purpose: To validate a new methodology to evaluate the impact of astigmatism in pseudophakia using an astigmatic defocus curve.

Setting: Hospital Oftalmológico de Brasilia, Brazil.

Design: Non-randomized cohort study.

Comparison of visual outcomes of bilateral dual-technology diffractive intraocular lens vs blended enhanced monofocal with dual-technology intraocular lens.

Purpose: To compare clinical outcomes after implantation of TECNIS Synergy (ZFR00V) intraocular lenses (IOLs) in both eyes and implantation of the TECNIS Synergy and TECNIS Eyhance (ICB00) combination in patients undergoing cataract surgery.

Setting: Department of Cataract, Hospital Oftalmológico de Brasilia (HOB), Brasília, Brazil.

Design: Prospective, interventional, randomized, parallel-group study.

Conventional Phacoemulsification Surgery Versus Femtosecond Laser Phacoemulsification Surgery: A Comparative Analysis of Cumulative Dissipated Energy and Corneal Endothelial Loss in Cataract Patients.

Purpose: To analyze whether femtosecond laser-assisted surgery leads to less cumulative dissipated energy (CDE) and decreased endothelial cell loss compared to conventional surgery.

Patients And Methods: This non-blinded, non-randomized, quasi-experimental clinical trial was conducted at one center and involved one surgeon. Patients with cataracts and 50-80 years old were included, and the exclusion criteria were radial keratotomy, trabeculectomy, drain tube implant, corneal transplant, posterior vitrectomy, and re-implantation of intraocular lens.

Evaluation of Life Quality of Patients Submitted to Cataract Surgery with Implantation of Trifocal Intraocular Lenses.

This study aimed to evaluate the quality of life and the satisfaction level of Brazilian and Chinese patients who underwent cataract surgery for Acysof IQ PanOptix Model TFNT00 (Alcon Laboratories, Fort Worth, TX, USA) implantation. This retrospective study enrolled 51 patients from China and 51 patients from Brazil. At the 3-month follow-up, uncorrected distance visual acuity (UDVA) at 5 m, uncorrected intermediate visual acuity (UIVA) at 60 cm, and uncorrected near visual acuity (UNVA) at 40 cm were evaluated; Catquest 9SF and the Near Activity Visual Questionnaire (NAVQ) were administered to the patients.
