Generally post-LASIK dry eyes are transient. If your dry eyes persist much longer than expected, you may want to have them properly assessed.
Most commonly, extended screen time (computer /iPads /iPhone) is the cause. Try resting your eyes every 20 min for 20 sec (by gently shutting your eyes) to maintain 20/20 vision. That is called the 20/20 rule :-)
Dehydration can exacerbate dry eyes, as can suboptimal diet. Supplements with good quality omega 3 fatty acids, usually in capsule form generally can help significantly. And don't have the fan / air conditioner right in your face as they will evaporate your natural tear film, which your eyes need.
If these simple measures still fall short, some specialty, prescription eye drops will usually help.
