Abstract

Objective

The digital transformation of daily routines has increased visual demands, especially at intermediate and near distances. The Devil multifocal intraocular lens (MIOL) design was developed to enhance intermediate visual performance. This design is a novel trifocal intraocular lens inspired by the fractal structure known as the 'Devil's staircase'. The aim of this research is to evaluate the visual performance of the Devil MIOL design in real patients.

Methods

The visual acuity defocus curve was obtained from 25 eyes of healthy volunteers using the Visual Adaptive Optics Simulator (VAO, Voptica SL, Murcia, Spain). Additionally, images of optotypes simulating those seen through the Devil MIOL design were captured to qualitatively illustrate optotype perception at different vergence values.

Results

Mean visual acuity values of the evaluation were 0.03 logMAR at 0.00 D vergence, 0.10 logMAR at +1.50 D vergence, and 0.11 logMAR at +3.00 D vergence, corresponding to far (optical infinity), intermediate (66.7 cm), and near foci (33.3 cm), respectively. The experimental outcomes were indeed slightly better than numerical results obtained previously in a model eye.

Conclusions

The Devil MIOL design provides satisfactory visual acuity across three primary foci and produces extended depth of focus between the intermediate and near foci.

使用临床适应性光学视觉模拟器评估新型三焦点眼内透镜设计的视觉性能。

目的：日常工作的数字化转型提高了对视觉的要求，尤其是在中近距离。Devil 多焦点眼内透镜（MIOL）的设计旨在提高中距离的视觉表现。这种设计是一种新颖的三焦点眼内透镜，其灵感来自于被称为 "魔鬼阶梯 "的分形结构。本研究的目的是评估 Devil MIOL 设计在实际患者中的视觉表现：方法：使用视觉自适应光学模拟器（VAO，Voptica SL，西班牙穆尔西亚）从 25 名健康志愿者的眼睛中获取视力散焦曲线。此外，还拍摄了模拟通过 Devil MIOL 设计看到的光学图像，以定性地说明不同辐辏值下的光学图像感知：评估的平均视力值分别为：0.00 D辐辏时 0.03 logMAR，+1.50 D辐辏时 0.10 logMAR，+3.00 D辐辏时 0.11 logMAR，分别对应远焦点（光学无穷远）、中焦点（66.7 厘米）和近焦点（33.3 厘米）。实验结果确实略优于之前在模型眼上获得的数值结果：Devil MIOL 的设计为三个主要病灶提供了令人满意的视力，并扩大了中间病灶和近处病灶之间的聚焦深度。
