Abstract
A synchronous vitreous lavage device for ophthalmology an includes a platform, a pair of main supporters, an auxiliary supporter, a pair of gears, a pair of movable seats, a pair of screw rods, and a clamp. When the screw rods rotate in different directions, the two movable seats move in opposite direction. Thus, the lavage device simultaneously drains bloody water from the eyeball, and injects lavage water into the eyeball by means of two syringes. The bloody water in the eyeball can be easily removed from the eyeball at a cheap cost. An ophthalmologic lavaging system is formed by connecting two regulating syringes through two three-way valves to the lavage device.
