Should I avoid heavy lifting after PRK laser eye surgery?
Frankly, there is no problem at all in lifting weights, and doing push ups. Some types of surgery requires a sutureless incision, and that can gape if you are lifting very heavy weights or so, though this would also be difficult. In your case, PRK involves no incision whatsoever, and the eye has healed already, since it has been some days since surgery. So go ahead and return to all normal activities.
