Laser ablation responsible for high increase in aberrations


Rochester, NY-Higher-order aberrations increase slightly after cutting a corneal flap with a microkeratome, there is minimal systematic change in the various modes of aberration with the exception of trefoil, and a slight hyperopic shift also occurs. However, after laser ablation there is a 40% to 60% increase in positive spherical aberration, according to Scott MacRae, MD.
