Hi, i have done my lasik surgery 3 weeks before but still see starbust and glare and halos. is it normal? is this problem correct after some time?

Probably go away: Some patients can get glare and halos at night after lasik surgery. They usually go away within the first 2-3 months, especially if you had a custom lasik procedure. If they persist more than 3 months, you definitely need to discuss with your surgeon.

Glare/haloes: Glare and haloes are normal in the post-operatively healing period after lasik. They should resolve with time. If they persist, you may have some residual refractive error causing the issue.
