"We assume that symptoms represent a form of corneal neuropathy rather than dry eye syndrome. [J Refract Surg. 2007;23:338-342.]"

Make assumptions and just keep slicing and lasering corneas, ignoring the damage you are inflicting on individuals and on society.

Do this, and you too can call yourself a "LASIK Surgeon".

from the full text:

Quote:
Corneal sensitivity is mediated by stromal nerves originating from the long ciliary nerves that penetrate the cornea and run forward in a radial fashion toward the center of the cornea. They form a network of nerves called the subbasal nerve plexus. Intact innervation is mandatory for normal corneal function. Ocular surface, lacrimal glands, and interconnecting nerves form a functional unit. A compromise in one portion of this reflex arch may result in ocular surface disease.


Quote:
However, patients reported ongoing ocular discomfort and symptoms resembling dry eye (photophobia, grittiness, foreign body sensation, and ocular irritation) significantly more than age- and [gender]-matched controls.


Quote:
De Paiva and Pflugfelder observed decreased corneal sensitivity after LASIK in patients without dry eye. They also found corneal hypersensitivity in patients with dry eye after LASIK compared with normal controls.


Quote:
We hypothesize that these symptoms of ocular discomfort could be in part derived from aberrantly regenerated corneal nerves.


Quote:
Other issues possibly contributing to dry eye symptoms after LASIK include differences in corneal curvature, whereas normal corneas show prolate profi les (ie, steeper in the center) and high conventional myopic LASIK produces oblate corneas. These changes in corneal
curvature may interfere not only with even tear distribution, but also mechanical rubbing due to the actual change in anatomy. Moreover, patients who seek refractive surgery are often contact lens intolerant and may have preclinical dry eye before surgery.

We're not dealing with "phantom pain" are we?
Amputees must sometimes deal with "phantom sensation" or "phantom pain."
Just a hypothesis. We must not assume; we must know.

"In a recent study of dry-eye symptoms following LASIK in high myopic patients, the investigators could not find demonstrable evidence linking the cause of the symptoms, but they assumed that symptoms represent a form of corneal neuropathy rather than dry-eye syndrome."

Gosh - I think they nailed LASIK as the cause because the post-LASIK patients had more dry eye symptoms than their gender and age-matched controls.

These investigators should invest in a confocal microscope and look a little further for some 'demonstrable evidence'.

With phantom pain there are also severed nerves involved.
