Comparison of the Early Clinical Outcomes between Combined Small-Incision Lenticule Extraction and Collagen Cross-Linking versus SMILE for Myopia

Figure 2

Refractive outcomes for small-incision lenticule extraction (SMILE) and combined SMILE with cross-linking (SMILE Xtra) at the end of 6 months postoperatively: (a) attempted versus achieved manifest spherical equivalent refraction (SEQ) correction in diopters for SMILE (left) and SMILE Xtra (right); (b) percentages of eyes within different diopter ranges of the intended correction in SEQ after SMILE and SMILE Xtra; (c) percentage of eyes attaining specified levels of astigmatism before (white) and after (grey) SMILE and SMILE Xtra.
