Corneal Wound Healing after LASIK Surgery

Daniel G. Dawson, MD =B7 Hans E. Grossniklaus, MD =B7 Henry F.
Edelhauser, PhD

In most cases, LASIK is immediately followed by loss of corneal
sensation over the flap and gradual disappearance of most of the
corneal nerves in the flap over the first 2 days after surgery.
Significant re-growth of the cut nerves starts between 1 and 3 months
after the procedure with corneal sensation typically recovering to
normal levels only by 6 to 12 months postoperatively. However, the
total length, morphology, and sensation of the re-grown corneal nerve
fibers never completely return to normal preoperative levels and only
reaches maximum levels by 1 to 2 years after LASIK.

This is nonsense..

After 2 years. the nerves regenerate to pre-operative levels.  Maybe
not 100%. but 98% is certainly good enough.   In fact, 3 months after
surgery, Enough nerve healing has occurred to do everything they need
to.

Also. their are 3 "trunks" of overlapping neves on the cornea.  If
the standard superior hinge is made, 2 of the trunks are cut. leaving
1 untouched - or 33% untouched.   If a nasal hinge is made.. only 1
trunk is cut. leaving 66% untouched to begin with.. and over time.
the cut trunk(s) regenerate.
Very few surgeons do nasal hinges because cutting the 2 trunks is not
a big deal.

Show us a study that demonstrates that nerves fully recover in 2 years.
Actually between 2 and 3 years they continue to decrease with less than
60% of the preoperative density on average.. at the 3 year point. Two
years is sort of the 'peak' and nerve density goes downhill once again.

Peripheral nerves regenerate. If this didn't happen almost no type of
surgery would be possible. The "flappies love to spread their gloom and
doom. Sorry Burchie, most people don't want to live like you.

Here's a way to look at this: if ten percent of corneal tissue is
removed during lasik, how could anyone have 100% of pre surgical nerve
tissue. You no longer have 100% of cornea.

You are full of it.  Glenn posted that study. maybe he will post it
again if you ask nicely.


Less than 60%?  hardly. if the surgeon wanted to. he could do a
nasal flap that would leave 66% untouched to BEGIN with. and then
over time, the remaining 33% would regenerate to preoperateve levels.
Also, since you have never been right about anything to do with
refractive surgery, you lack any credibility. so I do not have to
prove anything to anybody with a brain in their head.

Ive seen that study at least 3 times. Sounds like deja vu to me.
However its been proven lasik causes drier eyes. PRK is much more
forgiving because it doesnt use a flap so most nerves remain intact.
OrthoK is as forgiving as contacts, more so actually

Everything you said below is incorrect.   Congratulations on a perfect
score.
