Subjective assessment of mesopic visual function after laser in situ keratomileusis

The authors' study evaluated subjective reports of mesopic visual function after LASIK for spherical and spherocylindrical myopia and evaluated whether age, pupil size, treatment amount, residual postoperative refractive error, or other factors correlated with subjective findings. Preoperative, 3-month, and 6-month subjective patient questionnaires were administered. Results for questions about glare with night driving and glare with bright lights were tallied and evaluated using standard statistical methods. The results indicated that subjective reports of mesopic visual function after myopia LASIK improve overall. Worsened symptoms are most likely to occur in eyes with poor refractive outcomes. Correction of residual refractive errors may improve night driving and glare symptoms after LASIK.
