The Correlation Analysis between Corneal Biomechanical Properties and the Surgically Induced Corneal High-Order Aberrations after Small Incision Lenticule Extraction and Femtosecond Laser In Situ Keratomileusis

Figure 1

Comparison of the corneal hysteresis (CH) and the corneal resistance factor (CRF) between SMILE and FS-LASIK surgery (a, b); the ratio of CRF changes was significantly higher than that of CH after both the SMILE and the FS-LASIK surgeries (c). The ratio of CRF changes after surgery = ((preoperative CRF − postoperative CRF)/preoperative CRF), , .
