I would say that 2 months may seem like a reasonable length of time after Lasik refractive surgery for the refraction to stabilise.
However I routinely advise my patients to wait a minimum of 3 months after uneventful Lasik (and even longer if they have received adjunctive procedures including collagen cross-linking at the same sitting), to ensure that their refraction has stabilised, before considering any enhancement procedure.
Most importantly, you should demonstrate a stable refractive error before deciding on the appropriate time to consider enhancement. Certainly this would not be done before 3 months after the initial surgery, and best decided together with your surgeon. Best of luck with your enhancement, if at all even required!
