To investigate the one-year refractive outcomes and optical quality following PRESBYOND laser-blended vision (LBV).
This retrospective study included 20 patients who underwent PRESBYOND treatment between Jan 2019 and Aug 2020. The patients were asked to attend a follow-up 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.
The average patient age was 48.1±7.4y (range, 41 to 58y). The mean preoperative spherical equivalent was -7.59±2.39 D. 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; <0.001). The average binocular uncorrected near visual acuity increased from 0.34±0.28 to 0.97±0.07 (<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 (=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.
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.
研究PRESBYOND激光融合视力（LBV）术后一年的屈光结果和光学质量。
这项回顾性研究纳入了2019年1月至2020年8月期间接受PRESBYOND治疗的20例患者。要求患者在术后一年进行门诊随访。检查远视力和近视力以及主观验光。使用波前引导的个性化消融评估光学质量。在最后一次随访时完成一份评估光学质量和满意度的问卷。
患者平均年龄为48.1±7.4岁（范围41至58岁）。术前平均等效球镜度数为-7.59±2.39D。在一年随访时，2只眼（均为优势眼）矫正远视力（CDVA）下降了一行，而其余眼（38/40）的CDVA保持或提高。双眼平均未矫正远视力从0.15±0.03提高到0.90±0.26（小数视力；<0.001）。双眼平均未矫正近视力从0.34±0.28提高到0.97±0.07（<0.001）。非优势眼的球差为0.04±0.06µm，优势眼为0.09±0.09µm（P=0.02）。所有患者对手术结果满意或接受。主要抱怨与夜间视力障碍和相对较差的近视力有关。
在一年观察期内，PRESBYOND是矫正老花眼的一种安全有效的选择。光学质量和近视力值得进一步研究。
