Comparison
Population: participants aged 18‐60 years with myopia ranging in severity up to 12 diopters (D)
| Outcome | Effect | Evidence | Status / GRADE |
|---|---|---|---|
Uncorrected visual acuity (UCVA) of 20/20 or better | RR 0.96 [0.82, 1.13] | NR | Very low Downgraded: risk of bias, imprecision, indirectness |
Uncorrected visual acuity (UCVA) of 20/40 or better | RR 0.9 [0.67, 1.21] | NR | Very low Downgraded: risk of bias, imprecision, indirectness |

Eyes within ± 0.5 D of target refraction | RR 0.69 [0.48, 0.99] | NR | Very low Downgraded: risk of bias, imprecision, indirectness |
Postoperative corneal haze | RR 2.11 [0.57, 7.82] | NR | Very low Downgraded: risk of bias, imprecision, indirectness |
