Lasik Halo

Halos around light sources at night after Lasik, Bladeless Lasik, PRK, LASEK, Epi-Lasik, or RLE.

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..

[Supracor, Laser Correction of Presbyopia: One-year Follow-up Outcomes].

Cesk Slov Oftalmol. 2014;70(4):146-50

Authors: Machačová H, Vlková E, Michalcová L, Trnková V, Rybárová N

PURPOSE: Evaluation of one-year postoperative results after Supracor laser procedure.
METHODS: The study group consisted of 8 hyperopic patients (16 eyes) seeking alternatives to wearing glasses for both distance and near vision. These patients underwent Supracor refractive surgery in the Department of Ophthalmology of The University Hospital Brno in the time period from July 2012 to February 2013. The patient mean age at operation was 57,2 years (±4,6), mean binocular uncorrected near visual acuity was Jaeger No. 13, distance visual acuity 0,5 (±0,19). Average follow-up period was 15,5 months (±2,4). We evaluated binocular uncorrected and best corrected distance visual acuity (UDVA, BCDVA), near visual acuity (UNVA, BCNVA), and intermediate visual acuity (UIVA, BCIVA) 12 months after surgery, further the stability of visual acuity, objective refraction, mesopic contrast sensitivity, occurrence of complications, and patient satisfaction.
RESULTS: In all 8 patients, binocular UDVA of at least 1,0 was achieved. The mean spherical equivalent was +0,25 D (±0,64). UNVA was Jaeger No. 3 or better in 7 patients (68,7 %), 5 of them could read Jaeger No. 1. UIVA Jaeger No. 1 was achieved in 5 patients (62,5 %), Jaeger No. 2 in 2 patients (25 %), and Jaeger No. 4 in 1 patient (12,5 %). In all eyes, preoperative mesopic contrast sensitivity was within the normal range for the given age. Postoperatively it remained within the normal range in 11 eyes (68,7 %). In 5 eyes (31,3 %) we found adecrease below the lower limit in higher spatial frequencies (12 and 18 cycles/degree) during the entire follow-up period. According to the patient questionnaire, 7 patients (87,5 %) were fully satisfied with the outcome of the surgery and they felt independent of wearing glasses, 1 patient was dissatisfied. 7 patients (87,5 %) did not report the presence of photic phenomena (halo, glare), 1 patient suffered from these problems. We did not encounter any intraoperative or postoperative complications.Conlusion: According to our first experience, good distance, near, and intermediate visual acuity and arather high patient satisfaction can be achieved with the use of the Supracor procedure. Supracor seems to be asuitable method of presbyopia correction in motivated, adaptable patients who meet strict indication criteria. With regard to the small number of patients in our study group, agreater number of patient evaluations will be required in the future, and long-term results will be of interest as well.Key words: Supracor, presbyopia, LASIK, refractive surgery.
