At @ months postoperatively , the aspheric group had significantly better UDVA ( logMAR @ @ -LSB- Snellen @/@ -RSB- -LSB- range : -@ to @ -RSB- ) and lower mean residual spherical error ( +@ @ diopters -LSB- D -RSB- -LSB- range : -@ to @ D -RSB- ) than the wavefront-guided group ( logMAR UDVA @ @ -LSB- range : -@ to @ -RSB- ; MRSE -@ @ D -LSB- range : -@ to @ D -RSB- ) ( P = @ and < @ , respectively ) .
