A fuzzy halo< around light sources at
night is a relatively common complication of Lasik that usually resolves within the normal six-month healing
process. Halos are often worse or only exist in low light environments,
but can exist in daylight too. This Lasik night vision effect is
caused by inconsistent vision correction across the cornea.
Night vision halos are not limited to just Lasik, but may also
occur with conventional or wavefront custom Lasik, Bladeless Lasik, PRK, LASEK, Epi-Lasik, and RLE.
The symptom of Lasik halo are often related to Lasik
starbursts.
Lasik Halo Causes
Dry
eyes, edema (inflammation), and an incomplete treatment area
can cause or exacerbate Lasik halos. In nearly all cases the cause
of long-term Lasik halos relates to the size of the patient's pupil
and the size of the laser treatment zone.
Detailed Lasik Halo Information
See Lasik pupil size for details about the primary cause for Lasik
halos..
