Can the ablation area be increased during an enhancement to help diminish starburst or halo problems due to large pupils. I had the lasik surgery 9 months ago. My lasik corrected vision is +.25 on my dominent eye and -.75 on my non-dominent eye (monovision). I have an enhancement appointment next month to try to achieve 20/20 in both eyes because I am getting headaches from the monovision and for some lasik-induced astigmatism in my dominent eye that I would like corrected if possible. The night vision problem seems to be getting worse and it would be a big plus if it can be improved.

Thanks In Advance, Pat
