Corneal elevation in a large number of myopic Chinese patients

Highlights • Corneal elevation measurements are highly important in refractive surgery. • Previous normative databases for corneal elevation are based on limited geographic area and sample size. • Our study establishes a Chinese normative database for corneal elevation based on a large sample. • Thinner corneal pachymetry at the apex and greater anterior corneal astigmatism result in greater anterior corneal elevation values. • Younger age, greater anterior corneal astigmatism, lower anterior and posterior keratometry, and shallower anterior chamber depth tend to yield greater posterior corneal elevation values.
