Surgery performed 7 months ago Feb 2016. Vision was perfect but this week one eye is blurring? Not dry eye.

Was short sighted wearing contacts with a pwr of -4.50 and -4.75. Recently I've had disturbed vision. Assumed dry eye used drops. Gave myself an eye test left eye is perfect but right eye is blurry. Blurring from one eye disturbs the overall vision. Tested with drops and the blurry eye is still as blurry. Could there be other factors causing blur? Would surgeon consider top up for small corrections? Surgeon is an hour away would eye test at local opticians find issues with eye related to Lasik?
