All LASIK procedures start by creating a corneal flat. In the past this has been done using an oscillating blade, but now it is being replaced by the integrated interlace, which is a computer guided blade. Interlaced is the preferred way of performing LASIK, because it has less chance of complications and higher accuracy rate. It has been proven that a computer controlled blade is almost 100 times more accurate than that of handheld oscillating blades. This improves the chances of the coronary not getting scarred vision after LASIK making a complete recovery.
