Lasik Documentary on Corneal Neuropathic Pain

The Lasik documentary at left focuses on complications of Lasik, with an emphasis on post-Lasik neuropathic pain. The creation of the Lasik flap severs millions of corneal nerves. In "successful" Lasik outcomes, these nerves simply fail to regenerate fully. Another possible result is "traumatic neuroma," which acts as a constant pain generator in the cornea. The documentary language is Dutch, with English subtitles. Dutch physician Dr. Michael Brouwer suffers from corneal neuropathic pain. He and other Lasik victims in Holland discuss their experience with the Lasik industry and with suicidality. Dr. Edward Boshnick in Miami, FL (see talks about the billions of dollars at stake for the Lasik industry. Dr. David Barsook from McLean Hospital at Harvard University maintains that cutting of corneal nerves naturally leads to neuropathic pain, since the nerves with not heal properly for everyone. Dr. Barsook is supported by Dr. Morris Waxler, previously the chief research scientist on Lasik at the Food and Drug Administration maintains that the industry lied to the FDA about its adverse event rate (for more on this, see

Blurry Vision: In normal, healthy eyes with good vision, blurry vision indicates a need for prescription lens that adds additional power or corrects astigmatism that distorts the natural optics of the eye. Blurred vision can coexist with ghosting, smeared vision, or other visual aberrations.

Ghosted Vision: The term 'ghosting' was coined around 1957, and originally referred to the false image on a TV screen, caused by signal reflection. Ghosts are caused by residual astigmatism, or irregularities in the corneal surface. They vary in terms of transparency, size, and colors ghosted.

Glare: The term 'glare' is sometimes used to refer to the perception of any higher-order aberration. Here, the term is restricted to situations in which light seems to overflow, or 'seep outside,' its normal boundaries around light sources, or sources of reflected light, such as shiny objects.

Indoors Daytime Glare

Halos: Halos are usually huge globes of illuminated fog surrounding sources of light. Sometimes the globes seem to contain other globes, brighter and denser, nested two or more levels deep.

Loss of Contrast Sensitivity: Contrast sensitivity refers to the ability to distinguish between variations of lightness and darkness. Perceptually, this effect is similar to turning down the Contrast on your television or monitor: Eventually sharp boundaries are lost, objects merge together, as if a haze of grey soup had been poured over the visual field.

Starbursting: Starbursting refers to rays or fine filaments coming off lights. At night, these rays can become dramatically longer and denser. Starbursts are highly variable between patients, differing in terms of their size and shape, length of rays, the density of rays, and transparency (whether the light source is visible through the starburst).

Retinal Detachment: Information from receptors in the retina is aggregated at the optic nerve, and sent on to the visual cortex for further processing and interpretation. Portions of the retina that are no longer in communication with the brain may result in areas of blankness, blackness. Spatial distortions may exist at the margin of the detachment.

Visual Snow: Patients who complain of Visual Snow literally see what resembles "television snow," that is, specs or particles that blink on and off in their vision.


Hemianopia: Hemianopia refers to loss of vision in one half of the visual field of both eyes, most commonly on the right side. Causes of hemianopia include injury to the brain (temporal or occipital lobe) or optic nerve pathways from accident, infection, stroke, or tumor. Hemianopia may also affect the upper or lower halves of the visual field.

Visual Quality Disparities: Patients with bilateral eye injury or LASIK complications may report different aberrations in each eye. With both eyes open, these aberrations are synthesized to yield a composite image. However, one eye usually contributes more to the resulting composite than the other, a phenomenon known as "ocular dominance."


Pupil Size: Patients with complications from refractive surgery often report that their vision seems much better in bright light than dim light. Not only does bright light help compensate for Loss of Contrast Sensitivity, it also shrinks the pupil, reducing the visual aberrations caused by an irregular cornea.
