[The relationship between corneal astigmatism with a vector-based method and whole eye second order wavefront aberrations].

Objective: To investigate the relationship between corneal astigmatism and second order wavefront aberration in myopic eyes.

Methods: The corneal astigmatism and the whole eye wavefront aberrations of both eyes of 246 subjects were measured using the Humphrey corneal topography and the WASCA wavefront analyzer. According to axial of the corneal astigmatism, the subjects were divided into five groups (WR(0), WR(180), AR, OA(45) and OA(135)).
