Preoperative and postoperative refraction and visual acuity (mean±SD)
| Parameter | Preoperation | 36 months postoperation | P value |
| Sphere (D) | −5.35±4.30 | −5.84±4.11 | 0.050 |
| Cylinder (D) | −4.24±2.41 | −4.32±2.71 | 0.681 |
| Spherical equivalent (D) | −7.51±4.39 | −8.01±4.14 | 0.052 |
| CDVA (logMAR) | 0.32±0.28 | 0.26±0.25 | 0.025* |
*A significant difference was detected.
CDVA, corrected distance visual acuity; D, diopters; logMAR, logarithm of the minimal angle of resolution.
