The eye is a very sensitive organ. I had an injury to my eye a number of years ago. Post operative instructions no lifting, bending over or straining. Straining was explained as anything that would make you hold your breath. Such as using a wrench to loosen a bolt.

I am not saying that this is what you should do, but you should listen to your eye dr. Your eyes are something you want to protect. Let us know how things work out.
