Comparison of right and left eyes
| Right eye | Left eye | P-value* | |
|---|---|---|---|
| Refraction (D) | −1.34±3.67 (−13.25 to 4.25) | −1.34±3.59 (−13.75 to 4.25) | 0.238 |
| Cylinder (D) | −1.09±0.64 (−2.75 to 0) | −1.10±0.74 (−2.75 to 0) | 0.875 |
| Corneal curvature (mm) | 7.66±0.25 (6.90 to 8.39) | 7.67±0.27 (6.84 to 8.45) | 0.764 |
| Mean deviation** (dB) | −3.40±3.99 (−17.68 to 1.58) | −3.46±3.89 (−17.36 to 1.44) | 0.806 |
| IOP on first cycle (mmHg) | 13.7±2.8 (8 to 21) | 13.3±2.8 (7 to 21) | 0.188 |
| IOP on second cycle (mmHg) | 13.2±2.7 (7 to 21) | 13.1±2.9 (7 to 21) | 0.541 |
Notes: The data are shown as the mean ± standard deviation (range). The IOP values were obtained with SITA standard 24–2 testing protocol using a Humphrey field analyzer 750.
*
Paired t-test.
**
A P-value of < 0.05 was considered statistically significant.
