Abstract Details

Purpose:

To compare outcomes between wavefront-guided LASIK and SMILE 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:

University setting

Methods:

Eighty eyes of 40 consecutive patients underwent wavefront-guided LASIK surgery in one eye and SMILE surgery in their fellow eye. Eyes were randomized according to ocular dominance. The mean pre-operative spherical equivalent refraction was -3.37 +/-1.98 diopters and -3.48 +/- 1.94 diopters in the wavefront-guided group and SMILE group respectively (p = 0.93).

Results:

At post-op year one, mean spherical equivalent refraction was -0.11 +/- 0.27 diopters in the LASIK group and -0.13 +/- 0.53 diopters in the SMILE group (p = 0.73). At post-op month 12, 92% and 83% of eyes had an UDVA of 20/20 in the LASIK and SMILE groups respectively. Seventy-five percent of eyes had an UDVA of 20/16 in both groups. Fifty-eight and 17% of eyes had an UDVA of 20/12.5 in the LASIK and SMILE groups respectively. Eighty and 10% of eyes gained one or more lines of corrected distance visual acuity in the LASIK and SMILE groups respectively (p = 0.05). There were no significant differences in the induction of higher order aberrations between the two groups.

Conclusions:

Wavefront-guided LASIK and SMILE have similar clinical outcomes with excellent safety, efficacy and predictability in both groups. Wavefront-guided ASIK has faster recovery of uncorrected visual acuity and better 5 and 25% low contrast acuity compared to SMILE surgery.
