Abstract

Purpose: To compare objective quality of vision in patients undergoing phacoemulsification with implantation of a bilateral segmented multifocal intraocular lens (SMIOL).

Methods: A retro-prospective study included 110 eyes of 55 patients who underwent cataract surgery with bilateral SMIOL implantation. Patients were divided according to the type of implanted intraocular lens into group 1 (SBL-2, 62 eyes) and group 2 (SBL-3, 48 eyes). Postoperatively, monocular and binocular uncorrected distance visual acuity (UCDVA), corrected distance visual acuity (BCDVA), uncorrected intermediate visual acuity (UCIVA, at 66 cm), uncorrected near visual acuity (UCNVA, at 40 cm), corrected near visual acuity (BCNVA) and defocus curve were measured and evaluated. The follow-up period was 6 months.

Results: Mean UCDVA in group 1 (SBL-2) was 0.010 ±0.15 LogMAR monocularly, 0.01 ±0.10 LogMAR binocularly, and in group 2 (SBL-3) was 0.02 ±0.11 LogMAR monocularly and -0.07 ±0.09 LogMAR binocularly. Binocular defocus curves showed that the SBL-3 group performed better than the SBL-2 lens at a vergence of -1.50 D corresponding to 66 cm (center distance), averaging 0.03 ±0.11 LogMAR, while the SBL-2 group averaged 0.12 ±0.14 LogMAR (p = 0.01). The -2.50 D vergence characterizing near vision (40 cm) was achieved by the SBL-2 lens in our study at 0.33 ±0.15 LogMAR and by the SBL-3 lens at 0.00 ±0.11 LogMAR (p = 0.00).

Conclusion: Both SMIOLs provided very good vision at all tested distances 6 months postoperatively. The SBL-2 lens performed better in UCIVA, while the SBL-3 lens excelled in UCDVA and UCNVA.

SBL-2 和 SBL-3 分段式屈光透镜的早期视觉质量比较。

目的：比较接受超声乳化手术和植入双侧分段多焦点眼内人工晶体（SMIOL）的患者的客观视力质量：一项回顾性研究纳入了 55 名接受白内障手术并植入双侧 SMIOL 的患者的 110 只眼睛。根据植入的眼内人工晶体类型将患者分为第一组（SBL-2，62 眼）和第二组（SBL-3，48 眼）。术后测量并评估单眼和双眼未矫正远视力（UCDVA）、矫正远视力（BCDVA）、未矫正中间视力（UCIVA，66 厘米处）、未矫正近视力（UCNVA，40 厘米处）、矫正近视力（BCNVA）和散焦曲线。随访期为 6 个月：结果：第 1 组（SBL-2）的平均 UCDVA 为单眼 0.010 ±0.15 LogMAR，双眼 0.01 ±0.10 LogMAR；第 2 组（SBL-3）的平均 UCDVA 为单眼 0.02 ±0.11 LogMAR，双眼 -0.07 ±0.09 LogMAR。双眼散焦曲线显示，SBL-3 组在相当于 66 厘米（中心距离）的 -1.50D辐辏时比 SBL-2 组表现更好，平均为 0.03 ±0.11 LogMAR，而 SBL-2 组平均为 0.12 ±0.14 LogMAR（p = 0.01）。在我们的研究中，SBL-2 镜片的-2.50 D辐辏值为 0.33 ±0.15 LogMAR，而 SBL-3 镜片的-2.50 D辐辏值为 0.00 ±0.11 LogMAR（p = 0.00）：两种 SMIOL 镜片在术后 6 个月的所有测试距离上都能提供非常好的视力。SBL-2 镜片在 UCIVA 方面表现更好，而 SBL-3 镜片则在 UCDVA 和 UCNVA 方面表现出色。
