The blurring is due constant dry eye
which is why he has been advice Systane
eye drops. Even I would've adviced for 1-2hrly Refresh Liquigel eye drop and Systane like 3-4 times.
Actually people who have preoperative dry eye are prone to have exagerrated dry post refractive surgery(like KAMRA implantation
). But I'm not sure if one should go for a removal surgery again and if that would really help, if he is not having trouble driving & doing his regular reading.
Everytime you go in for a laser surgery
on your cornea, the poor cornea is being compromised....
Hope I helped...
