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

Figure 3

The changes in ΔMTF values (postoperative-preoperative MTF value) between SMILE and Femto-LASIK procedures at 1 week, 1 month, and 3 months postoperatively (up broken lines: Changes of MTF values at 1 week, 1 month, and 3 months after SMILE procedure at different spatial frequency; lower broken lines: changes of MTF values at 1 week, 1 month, and 3 months after Femto-LASIK procedure at different spatial frequency). (a) The change of MTF at vertical meridian at 3 mm pupil diameters; (b) the change of MTF at horizontal meridian at 3 mm pupil diameters; (c) the change of MTF at vertical meridian at 6 mm pupil diameters; (d) the change of MTF at horizontal meridian at 6 mm pupil diameters.
