To report 6-month visual and refractive outcomes following PRESBYOND Laser Blended Vision (Carl Zeiss Meditec) treatment using non-linear aspheric micro-anisometropia laser in situ keratomileusis (LASIK) for the correction of myopic and hyperopic presbyopia.
A retrospective, non-comparative study of 139 consecutive patients with a mean age of 53.13 ± 5.84 years (range: 42 to 70 years) treated with LASIK-induced micro-anisometropia using the MEL 90 excimer laser and VisuMax femtosecond laser (both Carl Zeiss Meditec). The target refraction was plano for distance eyes (dominant eye) and between -0.50 and -1.50 diopters (D) for near eyes. Patients were observed for 6 months.
A total of 278 eyes (78 myopic and 200 hyperopic) from 139 patients completed the study. Mean preoperative spherical equivalent (SE) was -3.40 ± 1.83 D (range: -0.50 to -8.25 D) for myopic eyes and +1.61 ± 0.98 D (range: -1.25 to +4.63 D) for hyperopic eyes. Mean postoperative SE refraction of distance eyes was +0.20 ± 0.35 D (range: -0.38 to +1.00 D) and -0.14 ± 0.42 D (range: -1.38 to +0.88 D) for myopic and hyperopic eyes, respectively. Mean postoperative SE refraction of near eyes was -0.90 ± 0.44 D (range: -0.13 to -2.25 D) and -1.21 ± 0.48 D (range: -0.13 to -2.25 D) for myopic and hyperopic eyes, respectively. Mean binocular uncorrected near visual acuity was 0.70 ± 0.28 logMAR (range: 0.32 to 1.00 logMAR) and 0.79 ± 0.27 logMAR (range: 0.25 to 1.00 logMAR) for myopic and hyperopic eyes, respectively. Mean binocular uncorrected distance visual acuity was 1.19 ± 0.18 logMAR (range: 0.63 to 1.25 logMAR) and 1.14 ± 0.26 logMAR (range: 0.40 to 1.25 logMAR) for myopic and hyperopic eyes, respectively. Stereoacuity was better than 100 seconds of arc in 79% of myopic eyes and 85% of hyperopic eyes and all vision quality scores were greater than 90 of 100. No eyes lost two or more lines.
The non-linear aspheric micro-anisometropia protocol resulted in safe and effective visual outcomes in patients with both myopic and hyperopic presbyopia. .
报告使用非线性非球面微离焦激光原位角膜磨镶术（LASIK）治疗近视和远视老视的 6 个月视觉和屈光结果。
回顾性、非对照研究，共纳入 139 例平均年龄 53.13 ± 5.84 岁（42 至 70 岁）的连续患者，使用 MEL 90 准分子激光和 VisuMax 飞秒激光（均为卡尔蔡司医学）诱导 LASIK 微离焦。目标屈光度为距离眼（优势眼）为平光，近眼为-0.50 至-1.50 屈光度（D）。患者观察 6 个月。
139 例患者中共有 278 只眼（78 只近视眼和 200 只远视眼）完成了研究。近视眼的平均术前球镜等效（SE）为-3.40 ± 1.83 D（范围：-0.50 至-8.25 D），远视眼的平均术前 SE 为+1.61 ± 0.98 D（范围：-1.25 至+4.63 D）。距离眼的平均术后 SE 为+0.20 ± 0.35 D（范围：-0.38 至+1.00 D）和-0.14 ± 0.42 D（范围：-1.38 至+0.88 D），近视眼和远视眼的 SE 分别为-0.90 ± 0.44 D（范围：-0.13 至-2.25 D）和-1.21 ± 0.48 D（范围：-0.13 至-2.25 D）。近眼的平均双眼未矫正近视力为 0.70 ± 0.28 logMAR（范围：0.32 至 1.00 logMAR）和 0.79 ± 0.27 logMAR（范围：0.25 至 1.00 logMAR），近视眼和远视眼的分别为 0.70 ± 0.28 logMAR（范围：0.32 至 1.00 logMAR）和 0.79 ± 0.27 logMAR（范围：0.25 至 1.00 logMAR）。近眼的平均双眼未矫正远视力为 1.19 ± 0.18 logMAR（范围：0.63 至 1.25 logMAR）和 1.14 ± 0.26 logMAR（范围：0.40 至 1.25 logMAR），近视眼和远视眼的分别为 1.19 ± 0.18 logMAR（范围：0.63 至 1.25 logMAR）和 1.14 ± 0.26 logMAR（范围：0.40 至 1.25 logMAR）。79%的近视眼和 85%的远视眼的立体视锐度优于 100 秒弧，所有视力质量评分均大于 100 的 90。没有眼睛失去两个或更多的线。
非线性非球面微离焦方案在近视和远视老视患者中产生了安全有效的视觉结果。
