My right eye is itching, blurred vision, sensitive to light and swollen and dry skin around eye what is this?

I have been to the ophthalmologist several times. She said at first allergies. Then she said eye infection caused by allergies. Then she said floppy eyelid syndrome. I don't know what to believe or what is going on. Does anybody else have the same symptoms, that can help me. I have itching eyes all day that just started only some months ago. Then my skin around my eye got dry rash about five flat bumps. I can't help to rub it itch. Then sensitive to light and my eye swells. Help the dr didn't it still itch.
