Hey, Dr. J, I've worked in an optometrist office for over 2 years and I can share some information about LASIK, PRK, and other corrective surgery. The office that I work at is in the northern part of Indianpolis, and we see approx. 12,000/year, and we have seen around 250 patients for pre-op and post-op LASIK & PRK procedures over the past 2 1/2 years. I perform the "pre-testing" for LASIK, so I get to talk with patients about the surgery and her their impressions and opinions about everything. For myself, I wouldn't have LASIK, PRK done because my prescription isn't strong enough to necessitate surgery, -1.25 OD -1.00 OS, and I have no problem with wearing correction, but everyone is different, and like every surgery, there are possible complications. While most patients that I have spoken with are EXTREMELY happy about the surgery, there have been some, I would say 20-30, who were not very happy about the procedure.
For example, after eye surgery is that a few patients have problems with dryness. A co-worker of mine (who is VERY TYPE A) was a -7.50 D prior to surgery, who had a history of dry eyes prior to the surgery ... she quit wearing contact lenses because of the dryness. A year after the surgery, she is on a continuous regiment of artificial tears and various ointments to provide her some comfort. Most patients do suffer from some initial dryness, but the problems resolve themselves within a month or two, because of the various eye drops used to "rebuild" (not the word that I want to use, but I can't think of the technical term) the epilethium (sp?). In addition, most patients have a problem with driving at night because of the halo effect caused by the incision. If you have ever driven at night with contact lenses, RGP's or SCL's, you will understand what I'm talking about. Whenever I have to drive at night, I have to wear my AR glasses because I have problems with the glare.
Another problem with LASIK is the chance for myopic regression. With a -2.50 diopter RX, I wouldn't think this is common, but there are a few patients who have LASIK who must have an enhancement because their prescription has "regressed." The aformentioned patient has regressed to a
-1.00 SPH O.D., -2.50 w/ -1.00 CYL O.S. My co-worker does the "pre-testing" at the Indianapolis 500 with a doctor that I worked with previously and a driver who was a -4.00 before surgery, has regressed to 20/40 3 years after the surgery. The enhancements can usually be done within a year of the surgery, after that point, the incision that is made to the cornea is usually too "settled" in order to perform the enhancement. From the literature that I have read from TLC (The Laser Center), most patients who have the surgery above say, -5.00, will more than likely regress somewhat after surgery.
Although these patients are somewhat atypical, people have to be realistic about the surgery. LASIK is "to reduce your dependence on vision correction", so if you expect to see 20/20 after surgery; granted, it may happen, but if you have that as a requirement, you may be SADLY disappointed.
