Comparison of the Optical Quality between Small Incision Lenticule Extraction and Femtosecond Laser LASIK

Figure 4

The changes in ΔMTF values at 6 mm pupil diameter (postoperative-preoperative MTF value) between SMILE and Femto-LASIK procedures at 1 week, 1 month, and 3 months postoperatively. (a) The change of ΔMTF at vertical meridian at 1 week postoperatively; (b) the change of ΔMTF at vertical meridian at 1 month postoperatively; (c) the change of ΔMTF at vertical meridian at 3 months postoperatively; (d) the change of ΔMTF at horizontal meridian at 1 week postoperatively; (e) the change of ΔMTF at horizontal meridian at 1 month postoperatively; (f) the change of ΔMTF at horizontal meridian at 3 months postoperatively. Significant differences () in ΔMTF between SMILE and Femto-LASIK group.
