Starbursting at Night

Starbursting - Driving at Night:
Driving at night can be extremely difficult for patients with complications from LASIK and other refractive surgeries. This simulation attempts to illustrate how a LASIK patient might see the headlights of a single oncoming car at night. The simulation is limited in many respects, and should not be viewed as capturing "the total night driving experience." First, starbursts vary on a variety of perceptual dimensions (see our Describing Starbursts page for a brief discussion and illustration). Second, night driving is much more complex than what is depicted in the simulation, particularly in the city, which has multiple cars and streetlights, all of which could exhibit the "night effects" that often accompany LASIK complications. Third, some patients report that they see nothing, or next to nothing, in dim light situations, due to loss of contrast sensitivity and a generalized dramatic decrease in the quality of vision. These patients either would not see the road, would see a blurry version of the road, or would see multiple roads.

This animation shows only one possible scenario; the size, shape, and density of starbursts are as diverse as the shapes of the post-LASIK corneas that see them.
