Background: This study aimed to estimate absenteeism costs and identify their predictors in non-hospitalized patients in Sweden.

Methods: This cross-sectional study's data were derived from the longitudinal project conducted at Uppsala University Hospital. The mean absenteeism costs due to COVID-19 were calculated using the human capital approach, and a Poisson regression analysis was employed to determine predictors of these costs.

Association of Patient Satisfaction with Cataract Grading in Five Types of Multifocal IOLs.

Introduction: This study investigated patient satisfaction levels in five premium intraocular lenses (IOLs). A secondary aim was to determine whether patient satisfaction was associated with the cataract grade before lens surgery.
