摘　　要：AIM: To investigate the one-year refractive outcomes and optical quality following PRESBYOND laser-blended vision(LBV).METHODS: This retrospective study included 20 patients who underwent PRESBYOND treatment between Jan 2019 and Aug 2020. The patients were asked to attend a followup outpatient visit one year after surgery. Distance and near visual acuity as well as subjective refraction were examined. Optical quality was assessed using wavefront-supported custom ablation. A questionnaire evaluating optical quality and satisfaction was completed at the last visit.RESULTS: The average patient age was 48.1±7.4 y(range, 41 to 58 y). The mean preoperative spherical equivalent was-7.59±2.39D. At the one-year follow-up, two eyes(both dominant eyes) lost one line of corrected distance visual acuity(CDVA), while the remaining eyes(38/40) maintained or gained lines of CDVA. The average binocular uncorrected distance visual acuity improved from 0.15±0.03 to 0.90±0.26(decimal vision;P<0.001). The average binocular uncorrected near visual acuity increased from 0.34±0.28 to 0.97±0.07(P<0.001). The spherical aberration was 0.04±0.06 μm in the nondominant eye and 0.09±0.09 μm in the dominant eye(P=0.02). All patients were satisfied with or accepted the outcomes of the surgery. The primary complaints were related to disturbances in night vision and relatively inferior near vision.CONCLUSION: Over the one-year observation period, PRESBYOND is a safe and effective option for presbyopia correction. The optical quality and near vision deserve further investigation.
