[Visual quality evaluation on changes of MTF and wavefront aberration after laser in situ keratomileusis].


OBJECTIVE To investigate the changes of the Modulation Transfer Function (MTF) and its effect on visual and optical quality with or without low and higher order wavefront aberration after conventional and wavefront guild laser in situ keratomileusis. METHODS It was a comparative case series. An aberrometer with Hartmann-shark sensor was used to measure… (More)
