Why does the IntraLase® Method allow very nearsighted people to have LASIK surgery?
When a person is very nearsighted, the cornea is steep. It curves forward at a steeper angle. The IntraLase® laser can follow that curvature and make a flap that’s precisely the right thickness throughout. In contrast, the microkeratome, making the flap mechanically rather than by a computer-guided laser, opens the door slightly to a flap being too thin, or not completely cut, because the steepness of the very nearsighted cornea is outside the range of traditional LASIK.
