How can I get the most accurate results from the pre-LASIK assessment?

Hi Ziqi

In general - the most accurate assessment for you would be performed by a team of experienced eye-care professionals (optometrists and ophthalmologists) who do the same assessment consistently on a large volume, and on a daily basis.

If the center that you choose has large operating volumes, it also means that the treatment algorithms will have been adjusted for the individual user and machines in order to optimize the surgical results for each patient.

Pre-Lasik assessment may be performed on the day of surgery, to as long as 1-2 months before the actual date of surgery, however some parts of the assessment may be repeated on the day of surgery (including refraction) if the interval between assessment and surgery is significant.

Just ensure that you are off your soft contact lenses for a minimum of 5-7 days prior to assessment / surgery, and at least 2 weeks for rigid gas permeable lenses.

Best of luck with your surgery!

Basically, stay off contact lenses as would be advised by your LASIK surgeon before you have any evaluation done. This is usually anything between 3 and 7 days for soft contact lenses and longer (14 days) if using hard contact lenses.

It is very much up to your surgeon to perform a thorough eye evaluation to determine if and when would be the optimal time for your surgery depending on your eye results and conditions.

Generally speaking, I try not to use measurements older than 3 months for the purpose of treatment. Though this is not a absolute rule and different surgeons may have different norms of practice.
