IntraLASIK is believed by Dr Boothe to offer a more fail-safe access to optical maser sight correction surgery. This is a final result of the superior precision of a computer-controlled laser as compared to that of a handheld mechanized device. The automatic device features a metal blade, which cuts across the cornea to produce the flap. IntraLASIK achieves the flap operation with a laser instead of a blade. Plus, it doesn't move around and across the cornea. These characteristics reduce the potential danger of complications.

IntraLASIK’s preciseness was proved in analyses conducted for the United States Food and Drug Administration (FDA) clearance of the laser, where the accuracy of flap thickness was certified at plus or minus 10 microns. Dr William Boothe is stronglyu convinced that accurate flap thickness is vital to a successful LASIK result, and flaps produced by IntraLASIK boast a uniform thickness from margin to margin. Once again, this level of accuracy is unprecedented in flap creation technology to date. In the end, improved flap stability was also proved with IntraLASIK flaps in analyses for the laser’s FDA compliance. Although the incidence of flap slippage is uncommon in LASIK, the results can be questionable. The confidence that the IntraLASIK produced flap will be firmly repositioned without incident furnishes added peace of mind for William Boothe's patients.
