About LASIK Surgery
Unfortunately, we have learned that the flap never completely heals back to the bed, resulting in permanent corneal weakness, forever.
NOTE: We no longer recommend or perform LASIK at Liberty Vision. Newer technology exists that is safer at the time of the surgery and forever after.
1. What are some complications of LASIK surgery procedures?
All eye surgery has similar risks such as infection, hemorrhage, blindness, loss of eye, or loss of life. LASIK surgery and Epi-LASIK surgery have incredibly good safety records, but with a lower percentage of problems than other eye surgeries. There is a risk of infection, but with modern ocular antibiotics used before, during and after the procedure, this risk is very low. Almost everyone who has LASIK surgery will suffer from some level of dry eye following the procedure, lasting varying periods of time from a few days to several years. Usually mild, the dry eye can usually be contained by using artificial tears in the form of eye drops. An important, but rare complication of LASIK surgery, but not of Epi-LASIK surgery, is dislocation of the flap with eye trauma forever following successful LASIK surgery. This is NOT a risk with Epi-LASIK.
2. What are the risks involved with LASIK surgery?
Although very rare, there have been a few reported cases in which the Microkeratome (the device which creates the flap) can cut more of the cornea than it is supposed to. When this happens, it can require further surgery to repair. Other risks include infection, irregular healing of the flap, over-correction, under-correction, and delayed development of progressive corneal thinning in the years following the procedure.
3. What are the most feared risks associated with LASIK surgery, and are there any long term risks?
Corneal ectasia-delayed development of progressive corneal thinning in the years following the procedure. In the past his would require corneal transplantation to correct. For those who have had LASIK care must be taken forever to avoid eye trauma because any dislocation of the flap during trauma to the eye must be repaired immediately or may also result in a corneal transplant being required. A newer and very exciting less invasive procedure to correct progressive corneal ectasia is Corneal Collagen Crosslinking, which can help the patient avoid a corneal transplant.
4. Are there limits to correction?
Yes, if the person’s prescription for nearsightedness is above about -10 diopters, above about +4 diopters for farsightedness, or if the astigmatism is greater than about 4 diopters, there are other procedures that would probably be more effective.
5. What if I move my eye during treatment?
With modern “tracking,” the laser instantly shuts down if the eye moves more than half a millimeter. I then get the patient repositioned and the laser starts up again where it left off.
6. What if I don’t keep looking at the red light?
I can’t start the laser treatment unless the eye is centered on the red light.
7. What if I blink when they’re doing the laser?
There is an eyelid holder in place that prevents blinking.
8. Can I have both eyes done with LASIK surgery at the same time?
Yes, either LASIK surgery or Epi-LASIK surgery can be done for both eyes the same day, and usually is done this way.
9. If I have one eye done at a time, what will my vision be like in between the first and second surgeries?
The operated eye will have good vision and the non-operated eye will be blurry, unless the patient wears a contact lens in the un-operated eye.
