Purpose.
To investigate the variations of corneal volume (CV) after small incision lenticule extraction (SMILE) and femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK) and analyze the influences of biomechanical properties on the changes of refraction and CV.
Methods.
Ninety-seven eyes of 97 patients undergoing SMILE and FS-LASIK were included in this retrospective study.
CV was measured with Scheimpflug-based corneal topography at preoperatively and at day 1, week 1, and months 1 and 3 postoperatively.
CV measured within 5 mm diameter was defined as central region volume (CV5) and between 5 mm and 10 mm diameter was defined as peripheral region volume (CV5-10).
An Ocular Response Analyzer (ORA) was used to assess corneal biomechanical properties including corneal hysteresis (CH) and corneal resistant factor (CRF).
The reduction of study parameters (△) were calculated by subtracting the preoperative value at various time points from the postoperative values.
Results.
CV had significant reduction after the SMILE and FS-LASIK procedure (P<0.05).
CV5 increased significantly from postoperative day 1 to month 3 (P<0.001) in SMILE, while both CV5 and CV5-10 increased significantly in FS-LASIK (P<0.001).
The increase in CV5 after SMILE was 0.11 ± 0.16 mm3,which was significantly different from FS-LASIK (0.20 ± 0.13 mm3, P=0.004).
In the SMILE group, △CV5 correlated with △CRF (r = 0.498, P<0.001) and △CH (r = 0.374, P=0.007).
In the FS-LASIK group, △CV5 and △CRF had a significant correlation (r = 0.363, P=0.012), but not with △CH.
Conclusions.
Dynamic changes in corneal volume were found after SMILE and FS-LASIK surgery.
The central region significantly increased after SMILE, while both central and peripheral regions increased following FS-LASIK in the early postoperative period.
SMILE was associated with less change in biomechanical properties per unit of reduction in CV compared with FS-LASIK.
