A capsular bag rehabilitation device has a belt body with an outer layer and an inner layer and a first space and a second space formed in between. The inner layer is provided with a plurality of vent holes connecting to the ambient environment and the second space. The outer layer, the inner layer, and airbag are welded at a predetermined interval distance. The unwelded parts form network air channels in the belt body. A controller has a first air duct, a second air duct, and a pump. The controller controls the pump to pump the first space through the first air duct, or withdraw air in the first space via the first air duct and pump it into the second space via the second air duct.
