If you have premium lenses like multifocals or some EDOF lenses, it’s very common (almost expected) to see halos or rings around lights at night initially. It’s basically a product of the lens design – multifocal IOLs have concentric rings that split light, and your eye might perceive those as rings around point light sources in low light. Similarly, you might see a bit of starburst or glare from oncoming headlights. The important thing is that for most people, these effects are mild and become a non-issue as the brain adapts and learns to filter them out. They are indeed a trade-off for the ability to see near and far. The vast majority of multifocal lens patients say that after a while, they hardly notice them, or it’s only in certain conditions (like driving in rain at night with lots of reflective surfaces). With monofocal lenses, halos are less common but can still occur if you have a bit of uncorrected astigmatism or dryness. So some nighttime halos could be addressed by a slight glasses prescription or better tear lubrication. For premium lens patients however,, consider halos and mild glare as part of the package – but for most, it’s an acceptable trade for day-to-day freedom from glasses. If you find them bothersome, you can try techniques like anti-reflective coating on glasses if you wear any at night, or avoid looking directly at lights, keep your windshield clean (it actually makes a big difference in reducing glare!). Also, over time, there’s neural adaptation – studies show night phenomena often significantly diminish by 3-6 months post-op. If halos are severe and not tolerable (which is rare, but possible in a small number of multifocal patients), you should discuss with your surgeon; you may need a small prescription adjustment with LASIK or PRK and in some cases, IOL exchange to a monofocal. But these are last resorts. By and large, mild halos are normal for premium lenses and a bit of patience and caution (like maybe avoid the most challenging night driving scenarios early on) helps. For monofocals, halos usually indicate another issue (like maybe a slight PCO forming or astigmatism), which can be fixed. So in summary: if you were warned pre-op about halos with a multifocal, what you’re experiencing at night is likely normal and will get better. It’s a normal trade-off: think of it like getting a wider range of vision in exchange for some nighttime artifact that usually doesn’t impair function significantly.
