The feeling of water moving in front of the eyes after glass excision may be caused by the effect of the gas or silicone oil injected after the removal of vitreous body, or the turbidity of the lens and aqueous humor damaged during the operation, or the feeling of water movement caused by retinopathy. 1. Too much or too little gas filled in the glass excision will lead to visual impairment, so that the original part of the water in the eye is squeezed and the feeling of water moving in front of the eyes all the time, which can be recovered usually after the gas is absorbed. Silicone oil filling may enter the front of the formation of droplets, resulting in a sense of floating, after removing the silicone oil symptoms can be improved. 2. Intraoperative lens damage or clouding of the anterior chamber, affecting the normal visual pathway, may also lead to the feeling of water movement in front of the eyes, to be treated after the primary disease symptoms can usually be improved. 3. It is very difficult to recover from the floating sensation caused by retinopathy, and it is usually necessary to go to a regular hospital for systematic treatment of retinopathy. After the glass excision operation, you should follow the doctor’s instructions to take good care of your eyes and review your condition. If you feel that there is water moving in front of your eyes all the time, it is recommended to go to a regular hospital for examination in time to avoid delaying your condition.
