I have so much wrong with my eyes....wet macular degeneration that require bi monthly injections, cataracts that need to be removed, and dry eye because of so many reasons. I was prescribed the generic Restasis and developed bad cough and asthma almost immediately, and then given Xiidra and cough was worse. Also headache. So now today, I am picking up a nose spray for dry eye and trying that method at the doctor's office who is the surgeon. I cannot have surgery until I can get dry eye under control. I am legally blind in my left eye due to cataracts. I have always been healthy and active, and never dreamed my slow down would be due to poor vision. :(.
