You will need an assessment appointment to find out if you are a suitable candidate for LASIK. It is usual to get a referral letter from either an Optometrist or your GP to see the surgeon. This is not essential, but it will help to reduce the Medicare gap payable for the initial consult. Soft contact lenses must be left out for seven days prior to your consultation and hard contact lens for one month. This is because the lenses change the natural shape of your eye and may give inaccurate results during testing.
