Why do some people need to repeat laser treatment?

Everybody heals differently. Even the 2 eyes of the same individual will heal differently. This is one of the main reasons on why the outcome is not as close to 20/20 as we want it too in about 3% of cases. There are also other variables at play that are difficult to control. That said, repeat laser treatments are very successful (and easy to do), i rarely have to do more than one repeat treatment on a patient.
