The Eyhance Toric intraocular lens (IOL) builds upon the Tecnis Toric platform, initially associated with considerable post-operative rotational instability. Version 2, the Eyhance Toric IOL has been modified to enhance rotational stability. This study evaluates the post-operative rotational stability of the Eyhance Toric IOL compared to the Clareon Toric IOL, recognized for its stable performance.
Patients undergoing cataract surgery received either the Eyhance or Clareon Toric IOLs. Placement was guided by the Barrett Toric Calculator at baseline (P0). IOL stability, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and refractive astigmatism were assessed at 6-24 hours (P1) and 3 weeks to 6 months (P2) post-operatively. IOL rotational measurements were recorded at each interval.
The study included 187 patients (median age: 74 for Clareon, 79 for Eyhance, p = 0.004). No significant differences were found in UDVA, CDVA, or refractive astigmatism at P2. Median rotation from P0 to P1 (3.0 vs 4.0 degrees, p = 0.091) and P0 to P2 (1.0 vs -0.5 degrees, p = 0.482) were not statistically different. However, the Clareon IOL showed less rotation between P1 and P2 (0.0 vs 1.0 degrees, p = 0.049). Absolute rotation from P0 to P1 (4.0 degrees), P1 to P2 (1.0 vs 2.0 degrees, p = 0.064), and P0 to P2 (4.0 vs 3.5 degrees, p = 0.095) were comparable.
The Eyhance Toric IOL demonstrated comparable rotational stability and visual outcomes to the Clareon Toric IOL. Modifications in the Eyhance design have successfully improved its rotational stability, positioning it as a viable alternative to the Clareon Toric IOL in clinical practice.
Eyhance散光型人工晶状体（IOL）基于Tecnis散光型平台研发，该平台最初与相当严重的术后旋转不稳定相关。第二代Eyhance散光型人工晶状体已进行了改进以增强旋转稳定性。本研究评估了Eyhance散光型人工晶状体与以稳定性能著称的Clareon散光型人工晶状体相比的术后旋转稳定性。
接受白内障手术的患者植入Eyhance或Clareon散光型人工晶状体。在基线时（P0）使用巴雷特散光计算器指导植入。在术后6 - 24小时（P1）以及3周至6个月（P2）评估人工晶状体稳定性、未矫正远视力（UDVA）、矫正远视力（CDVA）和屈光性散光。在每个时间间隔记录人工晶状体旋转测量值。
该研究纳入了187例患者（Clareon组中位年龄：74岁，Eyhance组中位年龄：79岁，p = 0.004）。在P2时，UDVA、CDVA或屈光性散光方面未发现显著差异。从P0到P1的中位旋转（3.0度对4.0度，p = 0.091）以及从P0到P2的中位旋转（1.0度对 - 0.5度，p = 0.482）无统计学差异。然而，Clareon人工晶状体在P1和P2之间的旋转较小（0.0度对1.0度，p = 0.049）。从P0到P1的绝对旋转（4.0度）、从P1到P2的绝对旋转（1.0度对2.0度，p = 0.064）以及从P0到P2的绝对旋转（4.0度对3.5度，p = 0.095）具有可比性。
Eyhance散光型人工晶状体表现出与Clareon散光型人工晶状体相当的旋转稳定性和视觉效果。Eyhance设计上的改进已成功提高了其旋转稳定性，使其在临床实践中成为Clareon散光型人工晶状体的可行替代方案。
