To evaluate the safety and efficacy of the iol-AMD technology (London Eye Hospital Pharma, London, UK), which includes two injectable, hydrophobic acrylic intraocular lenses (IOLs) in a pilot study of patients diagnosed as having cataract and dry age-related macular degeneration.
The cataract surgery and IOL implantation were performed after a preoperative evaluation using the iolAMD simulator in eyes with bilateral intermediate dry age-related macular degeneration. Outcomes were intraoperative and postoperative complications, subjective and objective visual acuity improvement, visual field changes, and postoperative diplopia.
Three eyes of 2 patients were evaluated. The surgeries were uneventful. All eyes gained monocular reading vision at the 1-week postoperative visit. One patient with monocular implantation recognized diplopia for distance vision. Preoperative corrected distance visual acuity ranged from 20/800 to 20/125 and corrected near visual acuity was 20/800 or less. Two months after surgery, corrected distance and near visual acuities increased to levels between 20/40 and 20/25 (uncorrected distance visual acuity was 20/60 to 20/32; uncorrected near visual acuity was 20/200 to 20/25).
These early results showed that the iolAMD simulator is a promising technology improving near and distance visual acuity in eyes with intermediate dry macular degeneration. The prismatic IOL effect did not lead to diplopia when implanted bilaterally. The surgery was safely performed.
在一项针对被诊断患有白内障和干性年龄相关性黄斑变性的患者的初步研究中,评估iol - AMD技术(英国伦敦眼科医院制药公司)的安全性和有效性,该技术包括两种可注射的疏水性丙烯酸人工晶状体(IOL)。
在对患有双侧中度干性年龄相关性黄斑变性的眼睛使用iolAMD模拟器进行术前评估后,进行白内障手术和人工晶状体植入。观察指标包括术中及术后并发症、主观和客观视力改善情况、视野变化以及术后复视情况。
对2例患者的3只眼睛进行了评估。手术过程顺利。所有眼睛在术后1周复查时均获得了单眼阅读视力。1例单眼植入患者存在远距离视力复视。术前矫正远视力范围为20/800至20/125,矫正近视力为20/800或更低。术后2个月,矫正远视力和近视力提高到20/40至20/25之间(未矫正远视力为20/60至20/32;未矫正近视力为20/200至20/25)。
这些早期结果表明,iolAMD模拟器是一种有前景的技术,可改善中度干性黄斑变性眼睛的远近视力。双侧植入时,棱柱形人工晶状体效应未导致复视。手术安全进行。
