Lost Your Night Vision After Lasik? This May Be Why

Ever play ball outside near sundown, and see the ball keep appearing and disappearing while in the air? Vision scientists call this "photon starvation." This is the brief period of time when it is becoming too dark for your normal daytime cone photo-receptors to work properly, but not yet dark enough for rod photo-receptors to takeover. At night with dim light you always see everything in black and white, not color. Some things can still appear in color if bright enough, such as a bright mercury-vapor streetlight which appears blue-white. Or a high pressure sodium streetlight will appear orange.

Functioning rod receptors are absolutely essential for driving at night.

I worked in vision research in the early 2000's at a university. One day circa year 2000 an email went around the department. Approximately 30% of the patients who underwent Lasik immediately LOST MOST OR ALL OF THEIR NIGHT VISION in the eye treated by laser. Night vision loss was found to be the result of a 400nm Lasik UV treatment laser.

As a result of using the 400nm wavelength, a portion of the UV laser light used during the Lasik eye lens re-shaping process passed through the eye lens and destroyed some/all of the rod photo-receptors used for night vision. This is why patients with Lasik rod damage can see during the daytime but not at night.

Field engineers for one large Lasik company quietly went to all their Lasik machine sites and replaced the 400nm UV treatment laser with a 200nm treatment laser.

THIS SERIOUS PROBLEM WAS NEVER PUBLICIZED IN THE MEDIA.
