Purpose: The OrbiTau surgical simulator is a synthetic eye model developed to enhance cataract surgical training. Herein, we aimed to describe the perspectives of Harvard's Ophthalmology faculty and residents regarding the effectiveness of OrbiTau.
Methods: A cross-sectional study was conducted in which 11 surgeons from the Massachusetts Eye and Ear Infirmary, with prior experience utilizing simulated phacoemulsification platforms, conducted cataract surgery with the OrbiTau.
Purpose: This review evaluated the impact of various public policies on the number of cataract surgeries performed annually by the Public Health System (SUS) in Brazil and its regions. The goal was to provide insights for managers and the medical community to assess the effectiveness of strategies to prevent cataract-related blindness.
Design: Trend studies based on literature review.

Evaluation of corneal incision in femtosecond laser-assisted phacoemulsification.
Clinics (Sao Paulo)
February 2025
Purpose: This study aimed to evaluate the accuracy and quality of healing of main corneal incisions in femtosecond laser procedures in cataract surgery.
Methods: It was a prospective, non-randomized, investigator-masked study. A total of 37 eyes of 37 patients with indication for cataract surgery were separated into two groups in this prospective, nonrandomized study: Femto group, with incisions automated by femtosecond laser (18 eyes), and Phaco group, with incisions made using a keratome (19 eyes).
Article Synopsis
- The study aims to explore how inflammatory biomarkers relate to corneal epithelial measurements in patients with keratoconus compared to healthy individuals.
- It involved a comparison of tear cytokine levels and hair cortisol concentrations from 100 patients, divided into 48 with keratoconus and 52 healthy controls, using advanced measurement techniques.
- Results showed that keratoconus patients had significantly higher levels of certain cytokines and cortisol, with notable correlations found between IL6 levels and specific epithelial thickness metrics.
Progression in the Number of Cataract Surgeries in Brazil: 10 Years of Evolution.

Objective: This study aimed to assess the frequency of cataract surgery in Brazil between 2010 and 2019 and determine the impact of public policies on preventing blindness, thereby providing evidence to conduct healthcare programs.
Methods: An analytical epidemiological approach was employed, which used data from public databases, specifically the Hospital Information System (SIH-SUS) and the Outpatient Information System (SIA-SUS). We focused on cataract surgeries conducted via phacoemulsification and extracapsular cataract extraction techniques between 2010 and 2019, mainly targeting senile cataracts within the Brazilian public health system.
Purpose: This study aimed to describe the behavioral patterns of data on cataract surgery performed in the Brazilian public health system before, during, and after the COVID-19 outbreak and estimate the setbacks generated by the pandemic to guide public policies.
Materials And Methods: This was an observational, longitudinal, and descriptive epidemiological study based on data retrieved from the public health system's databases of cataract surgeries performed each year and in each region from 2015 to 2022.
Result: In Brazil, compared with the average of the 5-years preceding the pandemic, a 23 % reduction in the number of cataract surgeries was observed in 2020, followed by a 21 % increase in 2021, compensating for the majority of patients that were not operated on.
Purpose: This review emphasizes the effect of light on visual efficiency, the impact of different lighting focuses, types of lighting, and their influence on vision and productivity. Light sources and standards are intriguing subjects for ophthalmologists. Guidelines regarding the level of lighting influence on visual activities can enhance visual performance.

This study wants to estimate the increase in medical schools, the demand for ophthalmology specialization, and evaluate learning opportunities in ophthalmology.
Methods: This was a retrospective study with research from the Ministry of Education and Brazilian Council of Ophthalmology database from 2002 to 2021.
