It's true that Intralase has been shown to cut thinner, more uniform planar-shaped flaps with smaller standard deviation in contrast with microkeratome blades which cut flaps which are thicker in the periphery and thinner in the center and less predictable in terms of intended thickenss. It makes sense that Intralase cuts fewer corneal nerves than blades. However, the anterior 100 microns of the cornea is more densely inneravated than the deeper layers of the cornea, so the difference in the amount of nerves that are cut may not be as dramatic as it seems...
