Methods. PSF 1000 analyzer was used to measure retinal image quality for eye of 26 subjects (spherical ranged from –3.00 ~-6.00Ds, astigmatism ranged from –0.75~-3.00Dc) fitted with three forms of full correction in random order : unaided eye, with rigid gas permeable contact lenses and toric soft contact lenses. The modulation transfer function curve was observed, 12 points of the MTF curve ( equivalent 12 points of LogMar VA) was used for analysis. Results.
