Axial length, refraction error, best corrected visual acuity（BCVA）, and macular scans by optical coherence tomography（OCT） were recorded at baseline, 6mo, 1, 3and 5y after the surgery, and the complications were noted.·RESULTS： There were no statistical differences in axial length, refractive error, or BCVA between the PSR group and the control group at baseline. At the end of the follow-up, the mean axial length was 29.79 ±1.26 mm in the PSR group, which was significantly shorter than that in the control group（30.78±1.30 mm）（P 〈0.01）, and the mean refractive error was-16.86 ±2.53 D in the PSR group, which was significantly lower than that in the control group（-19.18 ±2.12 D）（P 〈0.01）. A statistically significant difference in BCVA was found between the PSR group（0.51 ±0.25 log MAR） and the control group（0.62±0.26 log MAR） at the postoperative 5-year follow-up（P 〈0.01）. There were no serious complications during the 5-year follow-up period.·CONCLUSION： PSR can prevent axial elongation and myopia progression in eyes with pathological myopia.展开更多
