To investigate the outcomes of unilateral Supracor treatment to enhance near vision while maintaining good distance vision in hyperopic eyes.
This prospective interventional study includes consecutive hyperopic patients with presbyopia. All eyes underwent femtosecond laser-assisted keratomileusis treatment for hyperopia with an additional Supracor multifocal treatment algorithm in nondominant eyes. Monocular and binocular uncorrected and spectacle-corrected distance visual acuity (UCDVA and SCDVA), monocular and binocular uncorrected near visual acuity (UNVA), and distance-corrected near visual acuity at 40 cm and high-order aberration changes and complications were evaluated for 6 months.
Sixty-four patients with a mean age of 51.91 ± 3.64 were enrolled. After 6-month follow-up, the mean binocular UCDVA and UNVA were 0.03 ± 0.05 and 0.04 ± 0.06 logMAR, respectively. UCDVA (logMAR) of nondominant and dominant eyes was 0.30 ± 0.18 and 0.03 ± 0.05, respectively. Preoperative and postoperative mean ± standard deviation manifest refraction spherical equivalent was +1.84 ± 0.75 and -0.48 ± 0.57, respectively, in nondominant eyes and +1.77 ± 0.69 and +0.12 ± 0.33, respectively, in dominant eyes. No complications were observed.
Supracor procedure in nondominant eyes may improve functional near, intermediate, and distance vision without significant photic phenomena in presbyopic patients with low and moderate hyperopia.
探讨单侧Supracor治疗在改善远视眼近视力的同时保持良好远视力的效果。
这项前瞻性干预性研究纳入了连续性远视伴老视患者。所有眼睛均接受飞秒激光辅助角膜磨镶术治疗远视，非优势眼采用额外的Supracor多焦点治疗算法。评估6个月时的单眼和双眼未矫正及 spectacle 矫正远视力（UCDVA和SCDVA）、单眼和双眼未矫正近视力（UNVA）、40cm处的远矫正近视力以及高阶像差变化和并发症。
纳入64例平均年龄为51.91±3.64岁的患者。6个月随访后，平均双眼UCDVA和UNVA分别为0.03±0.05和0.04±0.06 logMAR。非优势眼和优势眼的UCDVA（logMAR）分别为0.30±0.18和0.03±0.05。非优势眼术前和术后平均±标准差的明显屈光球镜等效度分别为+1.84±0.75和 -0.48±0.57，优势眼分别为+1.77±0.69和+0.12±0.33。未观察到并发症。
非优势眼的Supracor手术可改善中低度远视老视患者的功能性近、中、远视力，且无明显的光现象。
