Two excerpts:


"Dr. Nilforoushan was surprised to find that even four years after LASIK, the flap remained weakened. The flap is believed to fibrose progressively with time. Even so, it appears that it does remain susceptible to trauma.
?If you have sufficient force in the correct direction, it can disrupt the flap because it is an inherently weakened area of the eye after LASIK surgery,? Dr. Nilforoushan said. This is bolstered by reports in the literature. ?Studies in animal models and those on postmortem human corneas have shown that the lamellar interface between the stroma and the flap always stays weakened.? A study by Kato et al. showed that in rabbits up to nine months, particularly in the area of the interface, wound healing continued to be disorganized.1 Similarly, in human corneas, investigators led by W.E. Philipp et al. saw only a minimal increase in staining of dermatan sulfate proteoglycan in the stroma along the lamellar edge. In addition, they found only a few collagen lamellae linking the flap and the stroma.2




"Overall, the most helpful strategy may be to forewarn patients of long-term risk, particularly those that may be prone to eye injuries, such as military personnel, boxers, or police officials, and possibly discuss refractive choices to consider other than LASIK".

excerpt:

In southern California, an eye surgeon prepared to perform a corneal transplant. The patient was anesthetized and the recipient eye readied for surgery, when suddenly the surgeon had to make an urgent call to the eye bank. Why? "I was in the middle of trephining a donor cornea, when it fell apart," he said.

"Fortunately, we were able to send a new cornea right away, and the surgeon finished the operation," said Ronald E. Smith, MD, medical director of the Doheny Eye Bank in Los Angeles. Later, back at the eye bank, researchers examined the ruined cornea and determined that it had had LASIK.

Quote:
If Dr. Chu has to do a LASIK en?hancement, he approaches that in a slightly different way, as well.

?I find the edge of the flap by de?pressing the cornea with Burato forceps with blunt ends,? he explains. ?Using this technique, you can sort of crack open the edge of the flap and peel it open in one maneuver without having to use a Sinskey hook to break the epithelium, minimizing the risk of epithelial in?growth.?

If a patient?s eye has epithelial in?growth postop, Dr. Melki will instill some fluorescein at the edge of the flap and look for staining that would indicate proliferating cells and an open fistula.

I tried to inform one of my friends that and mentioned orthokeratology as an alternative, a much safer one at that. Even PRK is the lesser of the two evils, but not something worth risking when orthoK is much better and safer. He said he was informed of the risks of lasik. Hes still not 100% happy with his lasik and is getting enhanced. If that doesnt work, he said he will go back to glasses! :roll: :evil:

Sporting LASIK:
Preventing active lifestyle injuries

by Maxine Lipner Contributing Editor

Quote:
"But, there is also a loss of strength after lamellar surgery - specifically loss of flap adhesion to the stromal bed."


Quote:
"You have a legal and moral obligation, and in legal terms that's the duty to warn," he said. "You need to inform your patient of the postoperative risk of flap complications and of the fact that the flap is not going to heal down as strongly as the surrounding stroma.

Practitioners should recommend to patients who've undergone refractive surgery that they use only council-certified eyewear for their sport, Hamill said.

Known Risk Factors for Ectasia

What do we know so far?

By William B. Trattler, MD

Excerpt:

Quote:
Because LASIK flaps can be easily lifted years after the original LASIK procedure, one wonders about the strength of its adherence to the underlying stroma. This information is important to know both for advising patients on their risks of flap dislocations with blunt trauma and understanding the extent to which the flap contributes to the overall strength of the cornea.

Analysis of a corneal button in a post-LASIK ectatic eye that underwent a corneal transplant revealed that the flap interface was devoid of bridging collagen fibrils and cells. Electron microscopy showed that the surfaces were very smooth and that there is essentially no wound repair in the space between the flap and the underlying stroma.3

The actual reduction in corneal strength due to LASIK was recently determined in a study of 21 cadaver eyes at Emory University in Atlanta.4 The researchers found that the adhesive strength of the LASIK flap was only 2.4% (?1.2%) compared with the normal interlamellar strength of a virgin cornea. In other words, the strength of the wound between the flap and the underlying stromal bed is reduced by 97.6% suggesting that the LASIK flap contributes little to the overall strength of the cornea after LASIK.

Relifting preferred over recutting flaps for LASIK enhancements, surgeons say

Quote:
Lifting is safer," said Vikentia Katsanevaki, MD. By using a blunt instrument and touching the cornea with a little pressure, the edge of the primary flap can be "easily recognized," she said.


Quote:
In my experience, there is no flap that cannot be lifted.

Thanks for posting this in the general forum, Kaleyedoscope. I'm copying it here, too.

http://www.escrs.org/PUBLICATIONS/EUROT ... nsflap.pdf

?The flap is really only connected by the hinge and a little bit of fibronectin and tenascin glue, whereas the stromal bed is intact. So the bed will move under the accommodatory twitches and the flap will move just a slight amount. I have seen over 70 eyes failed in the lab, and George Waring?s group in the US has over 500. Interestingly when you look at the histology of these failures it is not the bed that is failing, it is the flap. Our clinical studies have shown that LASIK is an unstable system
clinically, with changes being seen in the postoperative induced correction after about three years,? said Dr Marshall."
