Tags: optical zone

I had lasik done in July 2010 and now I'm wearing mini scleral lenses to help correct the halos, starbursts and glare issues I'm having. My question is that my optical zone was done at 6.5mm my pupils measured out to be 8.5mm, transition zone 1.25mm, and ablation zone out to 9mm. What would be the possible cause of the issues I'm having? My thought is its the mismatched optical zone to my true pupil size. He told me an enhancement could make my vision better but I'm just really scared.

Pupil Size and Night Glare

A common cause of night glare and haloes is a lower order aberration or prescription still left in the eye.
