Purpose
Both LASIK and SMILE are safe and effective in myopic refractive corrections.This study evaluates their safety and efficacy in a contralateral eye fashion.
Setting
The Laservision Clinical and Research Institute, Athens, Greece
Methods
This contralateral eye study included 140 eyes of 70 patients: one eye treated with ray-tracing optimized (RTO) LASIK (Wavelight Plus), while the fellow was treated with SMILE Pro (Visumax 800) and the RTO refraction . The following parameters were evaluated preoperatively and up to 3 months postoperatively: uncorrected distance vision acuity (UDVA), corrected distance vision acuity (CDVA), refractive error, corneal tomography, spherical equivalent (SE), defocus equivalent (DE), high order aberrations (HOA) and contrast sensitivity.
Results
At 3 months, 100% of the RTO LASIK group and 100% of the SMILE group had UDVA of 20/20, 62.3% and 34.5%, respectively, had UDVA of 20/16 (P < .002). SE (±0.50 D) was 98.5% for the LASIK group and 92.3% for the SMILE group. DE: (>0.5D) 0% and 15 % respectively. Residual tomographic cylinder (> 0.25 D) was 15.8% for the LASIK group and 52% for the SMILE group (P < .01). Contrast sensitivity was at par while HOA all under 0.8um RMSh.
Conclusion
RTO LASIK and SMILE Pro are both lamellar femtosecond laser assisted laser refractive corneal procedures. Short comparison of the two techniques in a randomized contralateral eye study both demonstrated impressive efficacy and safety.
