The BVI ISOPURE intraocular lens (IOL) (PhysIOL, Liege, Belgium) is a fully refractive, aspherical, monofocal lens based on isofocal technology. Isofocal technology provides cataract patients distance vision quality combined with improved unaided intermediate vision by accentuating the extended depth of field/focus (EDOF) effect whilst inducing minimal photic phenomena.
PubMed, Web of Science, Scopus, and Google Scholar searches were conducted for published research articles featuring the ISOPURE 123 IOL.
Excellent uncorrected and corrected binocular distance visual acuity of at least 20/25 can be achieved; uncorrected binocular intermediate vision of 20/25 or better in 81% and 50% at 80 cm and 66 cm, respectively, and 42% binocular near vision of 20/40 or better can be achieved. The defocus curve showed good visual acuity at far and intermediate distances with a depth of focus value of 1.50 D. Photic phenomena are minimal compared to other EDOF IOLs. Excellent contrast sensitivity was maintained compared to a standard monofocal IOL.
Studies show that this isofocal optic design IOL provides excellent visual performance for far vision and functional intermediate vision with an increased range of vision with few photic phenomena. This lens is an effective option for providing functional intermediate vision and correcting aphakia.
BVI ISOPURE人工晶状体(IOL)(比利时列日的PhysIOL公司)是一种基于等焦技术的全屈光性、非球面、单焦点晶状体。等焦技术通过增强景深/焦点扩展(EDOF)效应,同时产生最小的光学现象,为白内障患者提供远视力质量,并改善裸眼中间视力。
对PubMed、科学网、Scopus和谷歌学术进行检索,以查找发表的关于ISOPURE 123人工晶状体的研究文章。
可实现至少20/25的出色未矫正和矫正双眼远视力;在80厘米和66厘米处,分别有81%和50%的患者未矫正双眼中间视力达到20/25或更好,42%的患者双眼近视力达到20/40或更好。散焦曲线显示在远距和中间距离具有良好的视力,焦深值为1.50 D。与其他EDOF人工晶状体相比,光学现象最小。与标准单焦点人工晶状体相比,保持了出色的对比敏感度。
研究表明,这种等焦光学设计的人工晶状体为远视力和功能性中间视力提供了出色的视觉性能,扩大了视力范围,且光学现象较少。该晶状体是提供功能性中间视力和矫正无晶状体眼的有效选择。
