目得：为了评估用新的屈光旋转不对称多焦点人工透镜进行屈光透镜更换后的有效性、安全性、可预测性和患者满意度，方法：用SBL-3透镜（Lenstec，Inc.，基督教堂，巴巴多斯）植入进行评价。术前平均屈光球镜为+ 1.06 +/- 2.63屈光度（D）（范围：-8.25至+ 5.00 D），平均屈光柱镜为-0.51 +/- 0.46 D（范围：-2.00至0.00 D）。术后3个月评价单眼和双眼裸眼和矫正远视力、裸眼和矫正远视力、裸眼和矫正中视力、裸眼和矫正远视力、离焦曲线和患者满意度。平均术后裸眼远视力为单眼-0.03 +/- 0.09 logMAR（6/6 Snellen）和双眼-0.08 +/- 0.08 logMAR（6/4.8 Snellen）。平均单眼和双眼裸眼近视力分别为0.12 +/- 0.12和0.08 +/- 0.10 logMAR（6/7.5 Snellen）。散焦曲线显示出与中间视力相当的聚散度的轻微下降。虽然报告了一些夜视现象，但总体满意度很高。在这项研究中没有术中或术后并发症发生。结论：新的屈光旋转不对称人工透镜提供了良好的视力范围近，中间和距离。长期随访是必要的，以评价这种人工透镜的性能。
PURPOSE: To assess efficacy, safety, predictability, and patient satisfaction after refractive lens exchange with a new refractive rotational asymmetric multifocal intraocular lens.METHODS: One hundred six eyes of 53 patients after bilateral refractive lens exchange with the SBL-3 lens (Lenstec, Inc., Christ Church, Barbados) implantation were evaluated. The mean preoperative refractive sphere was + 1.06 +/- 2.63 diopters (D) (range: -8.25 to + 5.00 D) and the mean refractive cylinder was -0.51 +/- 0.46 D (range: -2.00 to 0.00 D). Monocular and binocular uncorrected and corrected distance visual acuity, uncorrected and distance-corrected intermediate visual acuity, uncorrected and distance-corrected near visual acuity, defocus curve, and patient satisfaction were evaluated 3 months postoperatively.RESULTS: At 3 months, 84.9% (90 eyes) were within +0.50 D of emmetropia. The mean postoperative uncorrected distance visual acuity was -0.03 +/- 0.09 logMAR (6/6 Snellen) monocularly and -0.08 +/- 0.08 logMAR (6/4.8 Snellen) binocularly. The mean monocular and binocular uncorrected near visual acuity were 0.12 +/- 0.12 and 0.08 +/- 0.10 logMAR (6/7.5 Snellen), respectively. Defocus curve showed a slight drop off for vergences equivalent to intermediate vision. Although some night vision phenomena were reported, overall satisfaction was high. No intraoperative or postoperative complications occurred in this study.CONCLUSIONS: The new refractive rotationally asymmetric intraocular lens provided good range of vision for near, intermediate, and distance. Long-term follow-ups are necessary to evaluate the performance of this intraocular lens.
