Abstract

Background: To assess clinical outcomes after implanting toric, extended-depth-of-focus intraocular lenses (IOLs) to correct low corneal astigmatism in eyes with cataracts.

Methods: 47 eyes were implanted with the AcrySof IQ Vivity Toric DFT215 IOL. Main outcome measures were refractive error, monocular uncorrected and corrected distance (UDVA/CDVA), uncorrected and distance-corrected intermediate (UIVA/DCIVA), and uncorrected near and distance-corrected near (UNVA/DCNVA) visual acuities, monocular defocus curve, rotational stability, and IOLSAT and QUVID questionnaires. Patients were assessed at 3 months postsurgery.

Results: All eyes had a postoperative spherical equivalent (SE) within ± 0.50 D and 97.87% (n = 46) had a refractive cylinder ≤ 0.50 D. The mean SE and refractive cylinder were - 0.10 ± 0.17 D and - 0.16 ± 0.24 D, respectively. The CDVA was ≥ 20/25 and ≥ 20/32 in 95.74% (n = 45) and 97.87% (n = 46) of eyes, respectively. The DCIVA was ≥ 20/32 in 85.11% (n = 40) of eyes and the DCNVA was ≥ 20/40 in 74.47% (n = 35). The mean values of CDVA, DCIVA, and DCNVA were - 0.02 ± 0.08, 0.14 ± 0.09, and 0.23 ± 0.12 logMAR, respectively. The defocus curve revealed good visual acuity at far and intermediate distances with a depth-of-focus of about 1.75 D. IOL rotation was 0.74 ± 1.13 degrees and all eyes had a rotation of less than 5 degrees. Patients reported either good or very good postoperative vision without eyeglasses under bright-light-conditions at distance (87.80%, 36/41) and intermediate distance (92.68%, 38/41). Between about 63.83%-72.34% (30-34) of patients reported no starburst, halos, or glare, or if experienced, were not bothersome.

Conclusions: The Vivity toric IOL implanted in eyes with low-astigmatism provides accurate refractive outcomes, good visual acuity at different distances and excellent rotational stability. Trial Registration The study was registered with the German Clinical Trials Register (DRKS00030579).

用于低角膜散光眼的非屈光性散光延焦深度眼内透镜。

背景：方法：为 47 只眼睛植入 AcrySof IQ Vivity Toric DFT215 IOL。主要结果指标包括屈光不正、单眼未矫正和矫正远视力（UDVA/CDVA）、未矫正和矫正远视力的中间视力（UIVA/DCIVA）、未矫正和矫正远视力的近视力（UNVA/DCNVA）、单眼散焦曲线、旋转稳定性以及 IOLSAT 和 QUVID 问卷调查。术后 3 个月对患者进行评估：所有患者术后球面等值（SE）均在 ± 0.50 D 以内，97.87%（n = 46）的患者屈光圆柱≤ 0.50 D。分别有 95.74% （n = 45）和 97.87% （n = 46）的眼睛 CDVA ≥ 20/25 和 ≥ 20/32。85.11%的眼睛（n = 40）的 DCIVA ≥ 20/32，74.47%的眼睛（n = 35）的 DCNVA ≥ 20/40。CDVA、DCIVA和DCNVA的平均值分别为- 0.02 ± 0.08、0.14 ± 0.09和0.23 ± 0.12 logMAR。散焦曲线显示，远距离和中距离视力良好，焦深约为 1.75 D。患者表示术后在强光条件下无需佩戴眼镜即可获得良好或非常好的远距离视力（87.80%，36/41）和中距离视力（92.68%，38/41）。约 63.83%-72.34% 的患者（30-34 例）表示没有星芒、光晕或眩光，或即使有，也不会造成困扰：结论：在低散光眼中植入 Vivity 散光人工晶体可获得准确的屈光效果、不同距离的良好视力和出色的旋转稳定性。试验注册该研究已在德国临床试验注册中心注册（DRKS00030579）。
