Does Having Lasik Make Your Pupils Dilate More Than They Did Pre-op?

Question

For some reason ever since I had lasik my eyes seem to get bigger than they were before lasik. I've read in articles that having unequal eye prescriptions will cause this. Not sure if its true. I only really notice this in low light or if I'm staring at something far away. Any ideas? Or maybe I've just never really paid to much attention to them.

LASIK does not usually change the size of one's pupils. Often, people are more noticeable about their vision and eyes after vision correction surgery. Near vision and bright light normally causes constriction of one's pupils. It is possible that your improved sight without glasses or contact lenses is making your pupil size more apparent to you. Speak with your eye doctor if you continue to notice this.

No but pupil size can vary. Lighting, medicines, alertness, alcohol, caffeine are just a few things that come to mind. For some people who are nearsighted, glasses can make the eyes appear smaller (minification) and for those with farsightedness, glasses can make the eye appear larger (magnification).
