night vision

[baseballfan]

Sorry for the multiple questions! How long does the night vision take to get better. I have halos and starbursts. I also have some blurryness in low light situations. Example, bars. I am 8 days post lasik. Thanks for all of your help.

I had my lasik done dec 21 and still have brighter than normal vision from headlights and any bright light in dark environment if thats considered starburst I dont know. It has diminished significantly though. I had to wear sunglasses to deal with it even at 8 dys and still apreciate sunglasses in sunlight and oncoming headlights more than before. Didnt have any per say halos after about a week or 2 not even a issue now.
Just today the dry cold breezy air thats set in hampered focusing off and on. My eyes get sandy feeling more easily. They stuck a plug in one eye at 1 week post op. I dont think it makes any significant difference.

Only blur for me is one eye short and one eye long range together not as sharp. So I wink one shut periodically if I need to really sharpen distance vision but most the time I just deal with the offset not that big a deal. I had my share of self induced vision issues throughout the first half of my life so it really doesnt matter. Its worth not needing glasses.

Poor night vision shortly after surgery can be cause by several issues.

Dry Eyes. Temporary dry eyes after Lasik is relatively common.

Edema. Your eyes just had surgery and swelling is reasonably expected. Uneven swelling can cause temporary astigmatism and induced refractive error.

Astigmatism. This means that a portion of your eye bends light differently. Induced or residual astigmatism can present as halos or starburts. Starbursts irregular in shape can indicate astigmatism.

Spherical Aberration. If your refractive error at the edge of your cornea is different than in the center, vision qualty can change in low light environments. If caused by dry eyes or edema, this may resolve with healing.

Undercorrection/Overcorrection. If you have residual refractive error the resulting slight blur can present as halos and starbursts at night. This can often be resolved with healing, contact lenses, glasses, or enhancement surgery (if appropriate).

I'm almost 6 months post op and still have bad night vision. It may never go away, but I'm hopeful it will improve somewhat over the next year or so.

peakaboo, do you have any residual refractive error or dry eyes? Does the night vision problem resolve with glasses?
