Are dry eye symptoms better after LASIK, or PRK?

Research has shown that dry eye symptoms are virtually the same for LASIK and PRK patients. Studies have yet to prove that one procedure causes more dryness than the other. 

For example, a 2012 study that was published in the journal Ophthalmology had patients undergo LASIK in one eye and PRK in the other.  The conclusion was that patients found no differences in perceived dryness from one eye to the other.

Research suggests that post-operative dry eye symptoms are best managed by ensuring a healthy ocular surface prior to laser vision correction, and following the post-operative drop instructions.
