If your laser surgery repaired the retinal tear, then you are lucky. I had laser surgery to repair my retinal tear, and it didn't work, so I had to have a buckle and vitrechtomy surgery which is much more complicated and difficult to recover from than laser. If I were you I wouldn't be so quick to exercise and I would wait at least six months before I exercised with Doctor's permission. You should ask your doctor when you do your follow-ups to make sure your retina tear is repaired and your retina stays attached.
