Abstract

Purpose: AT ELANA is a recently introduced trifocal intraocular lens (IOL) made of a hydrophobic material. The new IOL's optical function was examined against an equivalent version made of hydrophilic material. .

Setting: The David J. Apple Center for Vision Research, Heidelberg, Germany.

Design: Laboratory investigation.

Methods: This optical investigation was conducted on +20D samples of the AT ELANA and the AT LISA tri. The area under the modulation transfer function (MTFa) served as a quality criterion. Simulated visual acuity (VA) and defocus curves across +1 to -3.5D range were derived from an empirical formula according to ANSI Z80.35. Susceptibility to photic phenomena was evaluated by assessing the light distribution around a point light source.

Results: The two models demonstrated comparable optical quality. While at distance, a 4% improvement was noted with the AT LISA tri, the AT ELANA's near MTFa was 5% higher. Only a marginal difference (1%) was noted at intermediate. Both IOLs reached simulated VA of 0.0 logMAR far vision, 0.10 logMAR at 80 cm, and 0.05 logMAR at 40 cm. Still, the near range was slightly expanded with the hydrophobic model. The light-spread profile was comparable between the two trifocals.

Conclusions: The AT ELANA and the AT LISA tri demonstrated comparable optical quality and similarities in the potential for inducing photic phenomena. This study suggests that the hydrophobic trifocal IOL may provide visual range comparable to its hydrophilic counterpart. However, the asphericity change may facilitate the selection of a model that more effectively addresses specific corneal aberrations.

比较光学质量和模拟离焦曲线:亲水性和疏水性三焦点眼内透镜的对比分析。
目的:AT ELANA 是最近推出的一种由疏水材料制成的三焦点眼内人工晶体(IOL)。我们将这种新型人工晶体的光学功能与亲水性材料制成的同类产品进行了比较。.环境David J. Apple 视觉研究中心,德国海德堡:设计:实验室调查:这项光学调查是在 AT ELANA 和 AT LISA tri 的 +20D 样品上进行的。调制传递函数(MTFa)下的面积作为质量标准。根据 ANSI Z80.35 的经验公式得出了+1 至-3.5D 范围内的模拟视力(VA)和散焦曲线。通过评估点光源周围的光分布,对光现象的敏感性进行了评估:结果:两种型号的光学质量相当。AT LISA tri 的远距离 MTFa 提高了 4%,而 AT ELANA 的近距离 MTFa 则提高了 5%。中距离仅有微小差异(1%)。两种人工晶体的模拟视力都达到了远视 0.0 logMAR、80 厘米 0.10 logMAR 和 40 厘米 0.05 logMAR。不过,疏水性模型的近视范围略有扩大。结论:AT ELANA 和 AT L L 角膜塑形镜的散光曲线与这两种三焦点眼镜相当:结论:AT ELANA 和 AT LISA 三目镜片的光学质量相当,诱发光现象的可能性也相似。这项研究表明,疏水性三焦点人工晶体可提供与亲水性人工晶体相当的视觉范围。不过,非球面度的变化可能有助于选择更有效地解决特定角膜像差的型号。
