You could still have some astigmatism, refractive error, posterior capsule opacification, or corneal problems. Your symptoms are not normal and you should speak with your surgeon to find out the cause and the treatment. I am assuming you have monofocal lenses because if you have multifocal lenses, then halos are very common.
Thank you for the quick response. I forgot to mention in my first message that I have Restor lens. Is there any possibility that the halos will go away with time?
