i think can be done on same day but only on certain days have LASIK, so better check with clinic. I know cannot wear contacts for at least 3-5 days and some other avoidance things like perfume or fake eyelashes ( if Lord reaper happens to be a girl )HI LV Boi, thank for your reply. Can I ask Dr Lim pre-lasik check up and lasik can be done on the same day? or I have to take 2 days leave for check up and lasik? thanks
