Corneal irregularities vary widely among LASIK patients. Consequently, the visual aberrations reported by these
patients also vary widely. Patients may complain of blurry vision,
ghost images, starbursts, smeared images, halos, and loss of contrast sensitivity (inability to distinguish objects in dim light). Glasses and soft contact lenses cannot correct these aberrations. Some LASIK patients compare their vision to wearing dirty, uncomfortable contact lenses of the wrong power that are permanently stuck to their eyes.
Patients with visual disturbances after LASIK may use the vision simulators to communicate their vision to friends, family, physicians, and attorneys. Go to the vision simulators.
