A) Dry eyes, if you have dry eyes prior to the procedure they will be more dry after the procedure.
B) Your correction isn’t totally corrected – you may need an enhancement to get your vision perfect.
C) If you have Presbyopia (the need for reading glasses) and you have both eyes corrected for distance, you will still need reading glasses, you can talk to your doctor about possible Monovision or Mini-Monovision if you’re just about 40 or over 40.
