PURPOSE To evaluate visual outcomes 6 years after hybrid bi-aspheric multifocal central laser in situ keratomileusis for presbyopia correction (PresbyLASIK) treatments. METHODS Thirty-eight eyes of 19 patients consecutively treated with central PresbyLASIK were assessed. The mean age of the patients was 51 ± 3 years at the time of treatment with a mean spherical equivalent refraction of -0.57 ± 1.98 diopters (D) and mean astigmatism of 0.58 ± 0.57 D. Monocular corrected distance visual acuity (CDVA), corrected near visual acuity (CNVA), and distance-corrected near visual acuity (DCNVA), uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA), distance-corrected intermediate visual acuity (DCIVA), and uncorrected near visual acuity (UNVA) were assessed preoperatively and postoperatively for the dominant eye, non-dominant eye, and binocularly. Subjective quality of vision and near vision were assessed using the 10-item, Rasch-scaled, Quality of Vision (QoV) Questionnaire and Near Activity Visual Questionnaire (NAVQ), respectively. RESULTS At 6 years postoperatively, mean binocular UDVA was 20/18 ± 4 and mean binocular UNVA and UIVA were 0.11 ± 0.13 and -0.08 ± 0.08 logRAD, respectively. Spherical equivalent showed a slow hyperopic drift of +0.10 D per year with refractive astigmatism stable from 6 weeks postoperatively. Defocus curves showed an improvement of 0.4 Snellen lines at best focus from 1 to 6 years of follow-up, reaching preoperative levels. Compared to the preoperative status, the corneal and ocular spherical aberrations (at a 6-mm diameter) decreased and were stable from 3 months of follow-up. Questionnaires revealed a postoperative unaided QoV score comparable to preoperative scores and with an improved postoperative unaided NAVQ score compared to preoperative scores with best correction. CONCLUSIONS Presbyopic treatment using a hybrid bi-aspheric micro-monovision ablation profile is safe and efficacious even after 6 years postoperatively. The postoperative outcomes indicate improvements in binocular vision at far, intermediate, and near distances. An 8% re-treatment rate should be considered to increase satisfaction levels, including a 3% reversal rate. [J Refract Surg. 2020;36(2):89-96.].

LASIK术后使用混合双非球面微单视消融术进行老花眼矫正的长期结果。

目的评估混合双非球面多焦点中央激光原位角膜磨镶术治疗老花眼矫正（PresbyLASIK）后6年的视觉效果。方法评估19例连续接受中央PresbyLASIK治疗的患者的38眼。患者在治疗时的平均年龄为51±3岁，平均球面等效屈光度为-0.57±1.98屈光度（D），平均散光为0.58±0.57D。单眼矫正远视力（CDVA），矫正近视力（CNVA）和距离校正的近视力（DCNVA），未校正的距离视力（UDVA），未校正的中间视力（UIVA），距离校正的中间视力（DCIVA）和未校正的近视力（ UNVA）在术前和术后进行了优势眼的评估，非优势眼，双眼。分别使用10个项目，Rasch规模的视觉质量（QoV）问卷和近距离活动视觉问卷（NAVQ）评估主观视觉质量和近视力。结果术后6年，平均双眼UDVA为20/18±4，平均双眼UNVA和UIVA分别为0.11±0.13和-0.08±0.08 logRAD。球状等效物显示，每年的远视缓慢漂移为+0.10 D，术后6周起屈光散光稳定。散焦曲线显示，从1到6年的随访中，最佳聚焦状态改善了0.4 Snellen线，达到术前水平。与术前相比，角膜和眼球畸变（直径为6毫米）有所降低，并且从术后3个月开始稳定。问卷调查显示，与独立手术前评分相比，术后独立QoV评分与术前评分相当，且术后独立NAVQ评分较术前评分有最佳矫正。结论使用混合双非球面微单视消融术的老花眼治疗即使术后6年仍是安全有效的。术后结果表明在远，中和近距离双眼视力都有改善。应考虑将8％的再治疗率提高满意度，包括3％的逆转率。[J Refract Surg。2020; 36（2）：89-96。]。结论使用混合双非球面微单视消融术的老花眼治疗即使术后6年仍是安全有效的。术后结果表明在远，中和近距离双眼视力都有改善。应考虑将8％的再治疗率提高满意度，包括3％的逆转率。[J Refract Surg。2020; 36（2）：89-96。]。结论使用混合双非球面微单视消融术的老花眼治疗即使术后6年仍是安全有效的。术后结果表明在远，中和近距离双眼视力都有改善。应考虑将8％的再治疗率提高满意度，包括3％的逆转率。[J Refract Surg。2020; 36（2）：89-96。]。
