Q: Can we measure residual cornea thickness accurately after lasik treatment?

A:If you mean measurement of corneal thickness in microns, then yes, the same equipment used before Lasik can measure corneal thickness after Lasik. In case you mean very high accuracy, there are three different equipment that can be used and there is a minor difference in the measurements recorded by each one of them. In other words, your surgeon can measure your corneal thickness accurately before and after LASIK with one single instrument, while if you happen to go to different doctors, the measurement may vary by a few microns depending on the equipment used by each.
