Rings around lights after LASIK are called halos. They make headlights, streetlights, or other bright points seem to have a glowing circle around them, especially in dim settings or at night. Halos are a known side effect while the eyes recover and often fade over days or weeks, although they can last longer. Persistent or worsening halos should be discussed with your LASIK surgeon.
What do rings around lights look like after LASIK?
Halos are bright or blurry rings that appear around light sources. After LASIK, you may notice them when looking at car headlights, streetlights, traffic signals, illuminated signs, or bright indoor lights. They are often easier to notice at night, when the surroundings are dark and individual light sources stand out.
The rings may look like a soft glow surrounding a light or a more noticeable circle that makes the light seem larger than it really is. They can occur alongside other visual changes during recovery, including light sensitivity, blurred vision, or difficulty seeing clearly in dim conditions.
- Halos: Rings or circles of light around bright objects.
- Glare: Light appears unusually bright or uncomfortable to look at.
- Starbursts: Light seems to spread outward in streaks or rays.
- Hazy vision: Objects or lights appear less sharp or clear than expected.
These effects can feel similar, and more than one may occur at the same time. The American Academy of Ophthalmology identifies halos, glare, starbursts, and reduced vision in low light among the possible visual side effects of LASIK. Their presence does not automatically mean that the procedure has failed, but ongoing symptoms deserve attention if they affect everyday activities.
Why do halos happen after LASIK?
LASIK reshapes the cornea, the clear front surface of the eye, so that light can focus more accurately on the retina. During recovery, changes in visual quality can make bright lights appear different from how they looked before surgery. Halos are a recognized possible side effect of this procedure, even when ordinary daytime vision seems clear.
Changes in vision during recovery
Your eyes need time to recover after surgery, and your vision may not feel completely stable immediately. Halos and other nighttime visual disturbances can appear during this period. They often become less noticeable as recovery progresses, although the timing differs from person to person.
Dry eyes and tear-film changes
Dry eye is another common issue after LASIK. Tears help maintain a smooth, clear surface over the eye, and insufficient moisture can affect how clearly you see. You may notice fluctuating blur or changes in visual quality, including around bright lights. The U.S. Food and Drug Administration (FDA) explains that dry eye after LASIK can reduce visual quality and cause intermittent blurring and other visual symptoms.
Vision in dim lighting
Halos can be more noticeable at night because visual performance may be different in low-light conditions. Pupil size in dim surroundings is one factor considered when evaluating LASIK suitability, along with tear production and corneal characteristics. The FDA's LASIK Surgery Checklist highlights these factors and warns that glare, halos, and other visual effects can make night driving difficult for some people.
How long do rings around lights last after LASIK?
For many people, halos improve over the first days or weeks after surgery. Some visual side effects take several weeks or months to settle, so the presence of rings early in recovery does not necessarily mean they will be permanent. Your surgeon can give you a more relevant estimate based on your examination, the timing of your surgery, and how your vision is changing.
Mayo Clinic's information on LASIK eye surgery notes that glare, halos, and related night-vision problems commonly last a few days to a few weeks, while some other visual effects can take longer to resolve. A smaller number of people continue to experience troublesome visual symptoms over the longer term.
Pay attention to the overall pattern rather than expecting the rings to disappear on a specific day. Gradual improvement is reassuring, but halos that persist without improvement, become more noticeable, or interfere with work, reading, or nighttime activities should be discussed with your eye surgeon. Keep all scheduled postoperative examinations, even if your daytime vision seems satisfactory.
What can help when you see halos after LASIK?
There is no single remedy that is appropriate for every person who experiences rings around lights. The most useful first step is to follow your surgeon's recovery instructions and attend the recommended follow-up visits. These appointments allow the care team to check your vision, assess healing, and decide whether the symptoms need further evaluation.
- Follow your prescribed eye-drop schedule. Use the lubricating or medicated drops provided or recommended by your surgical team. Do not stop prescribed medication or add medicated eye drops without their advice.
- Allow time for recovery. Visual effects may change as the eyes heal. Report symptoms that persist, become more disruptive, or stop improving rather than assuming they will eventually disappear.
- Be careful in low light. If halos make objects or road signs difficult to see, avoid driving at night until your vision is safe for the task and your eye-care professional has advised you about driving.
- Protect your eyes as instructed. Follow the postoperative guidance about eye protection, hygiene, activities, and follow-up visits.
Do not try to treat persistent halos with leftover prescription drops or arrange another vision-correction procedure without an eye examination. The appropriate approach depends on what the examination shows and whether the main issue is dry eye, an ongoing change in visual quality, or another cause.
When should you contact your LASIK surgeon?
Contact your surgical team if rings around lights are not improving as expected, are getting worse, or are making daily activities difficult. You should also report new or unusual visual changes after the initial recovery period, even if the original halos seemed to be settling.
Seek urgent medical assessment for severe eye pain, sudden loss of vision, or rapidly worsening eyesight. Do not wait for a routine follow-up appointment if these problems occur. According to Cleveland Clinic's LASIK guidance, patients should contact their healthcare team when side effects worsen rather than improve, and severe eye pain warrants immediate medical attention.
At a follow-up visit, your eye-care professional may ask when the rings began, whether they occur in one or both eyes, whether they appear only at night, and whether your vision is changing. An examination can help assess healing, tear-film problems, and the quality of your vision. These findings help determine whether continued observation, treatment for dry eye, or additional evaluation is appropriate.
Can halos after LASIK be permanent?
Yes, persistent halos are possible, although many postoperative visual disturbances improve over time. The American Academy of Ophthalmology notes that most LASIK side effects are temporary but that some visual symptoms can remain in a small number of patients. Lasting halos are not proof on their own that permanent damage has occurred, and an eye examination is needed to understand the likely explanation.
When symptoms continue, your surgeon can assess whether there is a treatable factor and explain the available options. Further treatment is not automatically needed, and additional surgery should never be assumed to be the right solution. The decision depends on the examination findings, the effect on daily life, and the potential benefits and risks of any proposed treatment.
What should you remember about rings around lights after LASIK?
Rings around lights, or halos, are a recognized side effect of LASIK that often becomes less noticeable as the eyes recover. Dry eye and changes in nighttime visual quality may contribute to difficulties seeing lights clearly. Follow your postoperative instructions, be cautious with nighttime driving if your vision is affected, and contact your surgeon if the halos persist, worsen, or interfere with everyday activities. Severe eye pain or sudden vision loss requires urgent assessment.
