a A three-dimensional model of simulation device manufacted by 3D printing based on the idealization geometry in Fig. 2, magnified in 5 times. b The device model designed an inlet pipe, an outlet pipe, a silicone pad, two buffer spaces, a sink and many small holes (1, 2, 3, and 4). The fluid is infused by the inlet pipe into the inlet buffer space, through 2 circle of small holes (3, 4) evenly into the posterior chamber from all directions, passes through the pupil, enters the anterior chamber, uniform inflow of small holes (1, 2) and outlet buffer space, and eventually exits through the outlet pipe. The silicone pad can prevent water leakage. And the function of the water sink is to avoid the refraction of the laser. The device produced by 3D printing is shown in c and d
