a The false negative image taken with 14-MHz + THI. The anterior capsule of the lens is ruptured, the echo of the PC in the lens is regular and continuous, passage is seen in the lens (short arrow), the PC is not penetrated, and the PC is mistaken for being intact. b: The false negative LFUBM image. The ultrasound performance is similar to that shown in a (long arrow)
