Six-year changes in refraction and related ocular biometric factors in an adult Chinese population.

ABSTRACT:

Purpose

To investigate longitudinal changes in refraction and biometry in Chinese adults.

Design

Population-based prospective cohort study.

Methods

1817 subjects aged ≥ 35 years were randomly recruited from Yuexiu district, Guangzhou, China in 2008. Of which 1595 (87.8%) were reexamined in 2010 and 1427 (78.5%) were reexamined in 2014. Non-cycloplegic automated refraction and visual acuity test were performed at baseline and the 6-year follow-up examination for all participants. In addition, 50% of the participants were randomly selected for axial length (AL), anterior chamber depth (ACD) and lens thickness (LT) measurements using non-contact partial coherence laser interferometry. Lens power (LP) was calculated with the Bennett's equation.
