Lasik surgery is a popular procedure that can help improve vision, but it is important to be aware of the potential risks associated with it. After undergoing Lasik, many people experience varying degrees of glare and halos. These side effects are normal and usually fade away within two to three weeks, but can persist for up to a month. Flashes and halos occur when the eyes adjust to the new shape of the corneas, and are most severe during the first month after surgery.
With proper healing, these problems will eventually disappear. If no changes are seen after LASIK surgery, it is important to speak with an eye doctor. People with larger pupils are more likely to experience long-term halos and glare after the procedure. To reduce the risk of night vision problems, it is important to close your eyes while showering and avoid swimming until the corneal flap is fully healed.
You may also need to wear reading glasses or corrective lenses for some activities. Bryan Wolynski, OD, a board-certified community optometrist with over 30 years of experience in eye care, recommends that if you notice any flashes or halos after LASIK surgery, you should know that this is normal and that these side effects will go away over time. It is important to keep seeing your doctor and protect your eyes to avoid accidental injury.
