Loss of Contrast
I've noticed that since I've had intralase lasik things look strange when the lighting is dim, but when I go outside in daylight things return to normal. I had it July 2, 2010 so I'm sure I've lost some contrast. I've heard that it returns to pre operative levels withing 6 months. I've read where anybody that has refractive surgery loses it but then it returns. Just wondering how true this is. I've also notice it does the same in the evening when the sun goes down. I'm hopeing it will go away.

Loss of contrast
Loss of contrast sensitivity often means that you have a small amount of residual refractive error that was not fully corrected. If that error is sufficient and bothers you, your surgeon may be able to correct it with further laser or with glasses or contact lenses if you prefer. Refractive error that is very small or that does not bother the patient may be best to leave alone. Your surgeon can determine if this is the case with a good cycloplegic refraction. Haze can also...

Loss of contrast with Intralase LASIK
The Intralase works by making thousands of tiny explosions close to each other so that a plane of a flap is made. In inexperienced hands, it is certainly a safer way to make a flap, but it has a number of complications not seen with a microkeratome. Loss of contrast in most situations will improve with time as will most Intralase flap problems. The issue commonly has to do with the amount of laser energy used in the making of the flap. The frequent use of tear drops helps the surface of the...

Most intralast LASIK patients continue to improve
Indeed hopefully you will continue to improve like most Intralase LASIK patients. I agree that most patients notice the improvement within 3-6 months for a variety of reasons like neuro-adaptation (the brain readjusting), first healing, and the resolution of post-operative dry eyes. Using artificial tears, Restasis, and/or punctual plugs to improve the film often speed the recovery. Speak to your surgeon.

It depends
Sometimes this type of complaint after refractive surgery is temporary. But sometimes there are permanent issues due to corneal scarring, reduction in the tear film, residual or recurrent refractive error (need for glasses), or issues related to loss of focusing power (accommodation) in individuals around age 40 and above.
Talk to your surgeon -- s/he wants you to be satisfied.
