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..

Reversal of a presbyopic LASIK treatment.

Clin Ophthalmol. 2015;9:115-9

Authors: Ang RE, Reyes RM, Solis ML

We report on a 72 year-old pseudophakic patient who had been implanted with a monofocal intraocular lens, and who underwent a unilateral Supracor laser-assisted in-situ keratomileusis (LASIK) procedure to correct presbyopia and hyperopia. Uncorrected near visual acuity was improved, but the patient complained of glare, halo, reduced distance vision, and poor night driving vision due to treatment decentration. One year following the surgery, a reversal procedure was conducted with a wavefront-guided aspheric treatment to reverse the presbyopic correction while still maintaining the hyperopic correction. This resulted in 20/25 uncorrected distance visual acuity, and it eliminated the dysphotopsia symptoms. We believe that this is the first reported case demonstrating the ability to reverse the Supracor LASIK presbyopic procedure using wavefront-guided treatment in a case of an unsatisfactory outcome.
