Generally speaking, it is a usual problem when you have the blurred vision after the glaucoma surgery. As far as I can remember that my grandpa had the glaucoma surgery, some days later, the blurred vision happened to him, then we take him to hospital, the doctor just used a laser to open the bleb slightly, then my grandpa told us he can see very clearly. Pls relax yourself, because it just took about 10 seconds and was completely painless. Yeah, I know maybe the problem of my grandpa's is different with yours, and now the first step, also the most important step, is to go to doctor's office, because the doctor will check your eyes and find the reasons why you have the blurred eyes, because there are many reason that can cause the blurred eyes, such as the eye infection. Finally, the pros will take the right ways to cure it. Then, you had better not drive, read much and do something making your eyes tired. Good luck.
