Any subsequent laser vision correction surgery that occurs after your initial surgery, even years later, is referred to as an “enhancement.” It’s called an enhancement and not a “re-treatment” because the residual refractive error needing correction, if at all, is very tiny. It is difficult to predict who will need an enhancement in their lifetime. This not only depends on the unique way you heal, but also on the size of your initial treatment and on your age at the time of the treatment. There are natural changes to the inner-workings of the eye as we age that isn’t impacted by the LASIK procedure. Many treatments last well over a decade, and even with a little regression 10-15 years later, many patients don’t want the enhancement because they appreciate the near vision that they’ve regained. In fact, most patients needing enhancements after 10 years or more typically only want one eye sharpened up (see monovision discussion below). At Morris Eye Group, we offer patients lifetime enhancements free of charge (exclusions apply). This way you won’t have to roll the dice and concern yourself with whether your surgery will last 20 days or 20 years. Rest assured that when you get your LASIK at Morris Eye Group you will remain a part of our LASIK family forever.
