Most common complications after LASIK
I'm not sure I'd call it a complication, but the most common would be the potential need for a touch-up, or enhancement. This is a second surgery to fine-tune the initial result. The risk of needing this depends on your starting prescription, the laser used, whether wavefront technology is used, and the experience and skill of the surgeon. In my hands, the risk is below 5% for small to medium prescriptions, but climbs to 10% or even higher for very severe prescriptions.
