Purpose
To compare outcomes between wavefront-guided LASIK and topography-guided LASIK surgery in the treatment of myopia with and without astigmatism in a prospective, randomized eye to eye study. Outcome measures include quality of vision and quality of life metrics, high contrast snellen acuity, low contrast snellen acuity (5 and 25%), safety, predictability, efficacy and higher order aberration analysis.
Setting
Academic refractive surgical service
Methods
One hundred eyes of 50 consecutive patients underwent wavefront-guided LASIK surgery in one eye and topography-guided LASIK surgery in their fellow eye. Eyes were randomized according to ocular dominance. The mean pre-operative spherical equivalent refraction was -4.34 +/- 2.12 diopters and -4.32 +/- 2.14 diopters in the wavefront-guided group and topography-guided group respectively (p = 0.97).
Results
At post-operative month one, 93.33% and 86.67% of eyes had an UDVA of 20/20 or better in the WFG and TG groups, respectively; 76.67% and 63.33% of eyes had an UDVA of 20/16 or better in the WFG and TG groups, respectively; and 16.67% and 23.33% of eyes had an UDVA of 20/12.5 or better in the WFG and TG groups, respectively. There was no significant difference in the percentage of eyes that gained one or more lines of best corrected distance visual acuity in the WFG (26.67%) and TG (33.33%) groups, respectively (p = 0.70).
Conclusions
Wavefront-guided LASIK and topography-guided LASIK have similar clinical outcomes with excellent safety, efficacy and predictability in both groups.
