To evaluate the association between the orientation of the intermediate-vision zone and postoperative photic phenomena in eyes implanted with rotationally asymmetric multifocal intraocular lenses with + 1.5 diopters near addition.
Retrospective comparative case series.
We performed the photic phenomena test (PPT) to quantitatively evaluate photic phenomena at 1-3 months after cataract surgery with Lentis Comfort LS-313 MF15 or Lentis Comfort Toric LS-313 MF15T insertion (Oculentis; Santen Pharmaceutical). In cases of bilateral surgeries, only the right eye was included in the analysis. We also conducted a questionnaire survey about the photic phenomena.
The study included 96 eyes from 96 patients. The intermediate-vision zones of 44, 19, 19, and 14 eyes were fixed in the inferior, superior, nasal, and temporal directions, respectively. The measured PPT values for halo, glare, and starburst were equivalent in all the fixed directions. Eighty-four eyes (87.5%) perceived a triangle-shaped halo, and the direction of fixation for the intermediate-vision zone and the extension direction of this photic phenomenon were consistent in 94.0% of the eyes. Less than 10% of the patients responded "moderate" or "severe" for the triangle-shaped halo, glare, and starburst in fixed directions with low frequency in the questionnaire.
No qualitative or quantitative difference was found in photic phenomena in eyes implanted with the LS-313 MF15 or the MF15T regardless of the fixation direction. Our study revealed that many patients were aware of a triangle-shaped halo extending in the direction of the intermediate-vision zone.
评估 1.5 屈光度附加的旋转不对称多焦点人工晶状体植入术后中间视力区方向与术后像差现象之间的关系。
回顾性对比病例系列研究。
我们对接受 Lentis Comfort LS-313 MF15 或 Lentis Comfort Toric LS-313 MF15T（欧科林提；参天制药）植入的白内障患者进行术后 1-3 个月的像差测试（PPT），以定量评估像差现象。对于双侧手术，仅对右眼进行分析。我们还进行了关于像差现象的问卷调查。
本研究共纳入 96 例 96 只眼。44、19、19 和 14 只眼的中间视力区分别固定在下、上、鼻和颞侧。各固定方向的 Halo、Glare 和 Starburst 的 PPT 值测量结果相当。84 只眼（87.5%）感知到三角形 Halo，并且中间视力区的固定方向与该像差现象的扩展方向在 94.0%的眼中一致。在问卷调查中，94.0%的患者对固定方向的 Halo、Glare 和 Starburst 报告为“轻度”或“中度”，频率较低。
无论固定方向如何，植入 LS-313 MF15 或 MF15T 的眼的像差现象在定性或定量上均无差异。我们的研究表明，许多患者都意识到 Halo 呈三角形并向中间视力区的方向延伸。
