Representative images of allograft taken by Doppler ultrasonography. Before capsulotomy and evacuation, blood flow of the upper pole of the allograft was slightly poor, and diastolic flow decreased (end-diastolic velocity = 3.7 cm/s, resistive index = 0.67) (a). After decompression, allograft blood flow improved (end-diastolic velocity = 10.6 cm/s, resistive index = 0.61) (b)
