While I am very pleased for Catherine, I should point out that there is no scientific evidence suggesting any association between frequency or severity of vascular headaches (including migraine, cluster headache, etc.) and vision correcting laser care. Catherine did have moderate astigmatism which was nicely corrected by our treatment, but it is probably coincidence that she has not experienced any migraine headaches since her surgery.
We who provide vision corrective care do get to be the messengers of some very good news for many people that we treat. However, we should be careful not to take too much credit personally -- after all, it is the computer-guided, computer-controlled laser that does much of the work!
