I am almost 27 years old, male. I got LASIK done about 1.5 years back. Post the surgery, I'v always had some problem or the other with my eyes. I have on many many occasions felt one of my eyes had become smaller. I also had an eye infection soon after my LASIK but was it had not relation with that. I'v had difficulty watching movies in theatre/laptop most of the times. On and off, after consulting the doctor I have taken tear lubricants. This problem is especially severe in winter, I think. Now, since the past 2.5 months the problem has been increasing. Now I have immediate dry eyes while using laptop, tv or driving. Even if I use the lubricant five minutes before I sit down infant of the laptop, I get uncomfortable within minutes. One side of my heads starts to get strained, and it reaches the back of my head. This stress in my head then lasts for a while even if I don't strain my eyes. I have also been taking omega-3. I generally drink decent amount of water as well. I am also finding it very difficult to capture everything in front of me, which causes difficulty in driving/watching tv. Also, please note there have been days where I did not use laptop/tv/drive, but even then I get the strain in my head by evening. I have difficulty looking at people after a few seconds, and eventually become so cripple by night that I have to go to bed. As the evening progresses, so does my need to use the lubricant. What can be done?
