glare after cataract surgery

Had cataract surgery 4 years ago.  Had YAG procedure in late 2008.  Since the YAG, I've had streaks of light emanating from any source of light at night (streetlights, car headlights, etc).  Daytime vision is great.  Second doctor I went to said the surgery was done correctly, and that  it's the edge of the IOL that's causing the streaks.  He prescribed Alphagen to use when I drive at night - 1 or 2 times a week. I tested this in my house, and constricting the pupil did remove the streaks.  Question is - are there any other ways to address the problem?  A contact lens, perhaps?  As an aside, that eye is set to -1.25, so I need glasses or contact lens to bring the eye up to distance.

I assume there were no streaks prior to the yag.  May be enlarging the opening may help.

On the contrary, one of the doctors I've seen said the opening is too large.  And, if the Alphagen costricting the pupil helps remove the streaks, could it be that too much of the edge of the lens is exposed as opposed to too little?
