Abstract

PURPOSE

To compare the time spent on toric intraocular lens (IOL) implantation during cataract surgery using a manual-marking vs a digital image-guided system (t Verion) for toric IOL alignment.

SETTING

Instituto Oftalmológico Quirónsalud ophthalmology clinic, A Coruña, Spain.

DESIGN

Experimental and longitudinal study.

METHODS

A total of 98 eyes of 65 participants (68.2 ± 12.2 years) were divided into 2 groups: 49 eyes operated with toric IOL alignment using a manual-marking technique (manual group) and another 49 eyes operated using image-guided marking (Verion group). The primary variable for comparison between both groups was cataract surgery time. Other outcomes such as toric IOL misalignment, spherical equivalent, astigmatism, uncorrected distance visual acuity, and corrected distance visual acuity were also measured.

RESULTS

The total cataract surgery time was 2:09 minutes shorter (P < .001) with the Verion system (12:12 ± 2:20 in 49 eyes operated) compared with the surgical procedure performed using manual marking (15:27 ± 3:04 in 49 eyes operated). One month after surgery, there were no statistical differences in terms of toric IOL misalignment between the Verion (3.38 ± 2.95 degrees) and the manual group (4.66 ± 3.95 degrees). No statistical differences were observed between groups for refractive and visual outcomes (P ≥ .05).

CONCLUSIONS

The cataract surgery time was reduced when the procedure was assisted using the Verion system to align the IOL compared with manual marking, maintaining the same efficacy in terms of toric IOL misalignment, residual refraction, and visual acuity.

摘要

目的

比较白内障手术中使用手动标记与数字图像引导系统（t Verion）进行 toric 人工晶状体（IOL）定位时，toric IOL 植入所需的时间。

设置

西班牙拉科鲁尼亚 Quirónsalud 眼科诊所。

设计

实验性和纵向研究。

方法

共有 65 名参与者（68.2 ± 12.2 岁）的 98 只眼被分为 2 组：49 只眼采用手动标记技术（手动组）进行 toric IOL 对准，另 49 只眼采用图像引导标记（Verion 组）进行手术。两组之间的主要比较变量为白内障手术时间。还测量了 toric IOL 错位、等效球镜、散光、未矫正远视力和矫正远视力等其他结果。

结果

使用 Verion 系统（49 只眼手术的总时间为 12：12 ± 2：20）比使用手动标记（49 只眼手术的总时间为 15：27 ± 3：04）的手术时间短 2：09 分钟（P<0.001）。术后 1 个月，Verion 组（3.38 ± 2.95 度）和手动组（4.66 ± 3.95 度）的 toric IOL 错位差异无统计学意义。两组在屈光和视力结果方面无统计学差异（P≥0.05）。
