Background,Motivation and Objective In ophthalmic ultrasonography the crystalline lens is known to be the main source of phase aberration,as ultrasounds(US) propagate about 10 ％faster than in the surrounding intra-ocular medium.Consequently,it impairs significantly both spatial and contrast resolution of axial B-scans,and in addition causes important distortion,especially on the ocular fundus.
