It is not uncommon to have some transient dryness of the operated eye(s) after PRK, LASIK and cataract surgery. Although each procedure varies somewhat in terms of what is exactly done to the eye, it stands to reason that the nerves of the eye will become temporarily hyperactive after surgery. In my Baltimore, Maryland office, we will provide you with several bottles of very good, unpreserved artificial tear drops, which should be more than enough to get you through the first week of recovery. Typically, by the time we see you for the next post op visit, the symptoms of dryness are gone. It should also make sense that we see a little more trouble with dryness in the winter months, because the air is naturally drier and the heat is on. Dryness related to either corneal surgery or cataracts is temporary and, frankly, more of a nuisance for the patient than a clinical worry.
