In studies performed at the University of Arizona Department of Ophthalmology, we evaluated the outcomes for LASIK and LASEK. These are represented in the following graph.

In general, these results are are similar to those reported in national studies. The key to remember is that the vast majority of patients can function quite well without glasses 95% of the time. Some patients may still require glasses for driving at night. If you are at the presbyopic age (over 40), you will definitely require glasses for reading.
