Night vision usually NOT a problem after LASIK any more
In the early days of LASIK there was a high incidence of night vision problems, especially in patients with larger pupils, or flat corneas. Today we have more understanding of how to reshape corneas and avoid this problem and this is described as prolate optimized or wavefront optimized custom treatments. In simpler terms, the eye is prolate or comes to a steeper area in the center and this is the same shape that eagles have which gives excellent distance vision. The early LASIK...
Night vision after LASIK
Night vision was an issue with patients after having LASIK using older technology. Patients with large amounts of nearsightedness, astigmatism or farsightedness were at greater risk using these older lasers. A large pupil size was also felt to be a risk factor with first-generation lasers. Newer wavefront-guided lasers have clearly established that the vast majority of these patients can now be treated without causing problems with night vision. In fact, using the VISX wavefront guided...
Night vision after LASIK vs LASEK
You should demand to get hi-def, custom, wavefront correction, that is an option if you want the best possible night vision, this is a necessity you should also ask them what your pupil size is, as various studies have shown different things, but most refractive surgeons would agree that the chance of your having halos after is somewhat related to if you have a large scotopic pupil (pupil size in dim light). this is because as your pupil dilates at night, it may dilate past the...
LASIK and Night Vision
LASIK in 2010 should, if anything, improve night vision. This was not true 10 or 15 years ago, however, and many patients noted subtle glare and halos after laser vision correction. The difference now is twofold. First, is the existence and use of bladeless(Intralase) technology to create the corneal flap that is the first step of the LASIK procedure. This allows for a safer, smoother corneal flap that sets things up perfectly for the second great advance in technology, which is...
