Haakenstad et al. (1) examined health-care access and quality (HAQ) by assessing performance for the first time for three select age groups: the young (ages 0–14 years), working (ages 15–64 years), and post-working (ages 65–74 years) groups in 204 locations from 1990 to 2019.

The authors found that between 1990 and 2019, the HAQ Index increased overall (by 19·6 points), as well as among the young (22·5), working (17·2), and post-working (15·1) age groups.

Large differences in HAQ Index scores were present across Socio-demographic Index (SDI) levels in 2019, with the overall index ranging from 30·7 (28·6–33·0) on average in low-SDI countries to 83·4 (82·4–84·3) on average in high-SDI countries.

Population-based studies were used to establish estimates of effective refractive error coverage (eREC) among adults aged 50 years and older in Bourne et al. (2).

The authors analysed data from 565,448 participants of 169 population-based eye surveys conducted since 2000 to calculate eREC, and found that global distance eREC increased from 2000 to 2021 by 19·0%, with eREC being higher in men and reduced with increasing age.

The analysis highlighted inequitable access to high-quality refractive services among women and older persons.
