Glad that your vision is great after PRK!  Sometimes dry eyes from staring at the computer can make the eyes feel strained and tired.  How old are you?  PRK is usually done to correct distance vision, so you may require a small reading correction for up close or for the computer.  Let your eye surgeon know about your concerns so that they can recommend the right treatment.  Get well soon!

From the sounds of your symptoms it appears that you are experiencing eye strain very reminiscent of presbyopia.
