The actual vision correction provided in blade-free LASIK -- the part done by the excimer laser inside the cornea -- is exactly the same as in standard LASIK. However, some studies suggest that the blade-free technology helps prevent occasional complications with the flap that interfere with visual acuity.
Indeed, several studies of patients who had standard LASIK in one eye and Intralase in the other found that they tended strongly to prefer the Intralase eye.
The blade-free procedure may also help reduce patient anxiety about the operation. At least LASIK surgeon reports that when given a choice, three-quarters of their patients prefer the Intralase before any surgery is even performed.
