ABSTRACT Objective: To evaluate public knowledge of keratoconus in Brazil and identify gaps to guide future educational strategies. Methods: A cross-sectional online survey, based on the 2015 Global Consensus on Keratoconus, was distributed via social media and an ophthalmology bulletin. Adults (≥18 years) participated anonymously after providing informed consent. The questionnaire assessed demographics, ocular history, and keratoconus-related knowledge. Descriptive statistics summarized the data, and associations were analyzed using chi-square and nonparametric tests (5% significance level). Results: A total of 879 […]

The patients received three biweekly sessions on the eyelids and with the Lumenis OPT M22™ equipment. Glandular expression was not performed […]

ABSTRACT Objective: To evaluate the agreement between the Eyestar900 and IOLMaster700 for biometric measurements and assess their interchangeability. Methods: This retrospective study analyzed the following parameters: anterior keratometry, axial length, anterior chamber depth, white-to-white diameter, and lens thickness. Agreement was assessed using intraclass correlation coefficients, Bland-Altman plots, and scatter plots. A paired t-test was used to evaluate statistical differences. Results: A total of 43 eyes from 33 patients were analyzed. The mean differences were 0.03 D for keratometry, 0.08 mm […]
