METHODS: Forty consecutive eyes underwent uneventful LASIK for treatment of moderate hyperopia (+3.82 ± 0.63 diopters [D] [+2.75; +5.125]). WebIn physics the wavefront of a time-varying field is the set (locus) of all points where the wave has the same phase of the sinusoid. For waves propagating in a unidimensional medium, the wavefronts are usually single points; they are curves in a two dimensional medium, and surfaces in a three-dimensional one. csg champigny
