Right eye, lasik 12 yrs ago, cataract surgery 2 yrs ago. Suddenly getting big starbursts outside at night. Anti-glare glasses don't help - what would?

Check up. Have your eye md check your refraction and examine the eyes. You have had cataract surgery in the past and your eyes may be developing posterior opacification of the capsule that surrounds your intraocular lens implant. Your eye md can tell you if a laser capsulotomy would help clarify you vision, or if is just a glasses prescription change.
Ophthalmologist time. This could be many things. Most likely is probably some scarring in the tissue that holds your lens implant in place. If that is the problem, it is easily fixed with a quick laser procedure. But the only way to know is to see your ophthalmologist.
