The purpose of this study was to assess the clinical outcome after a bilateral implantation of an extended depth of focus intraocular lens in comparison to a monofocal intraocular lens.
Department of Ophthalmology, Charité-Medical University Berlin, Germany.
A total of 60 eyes of 30 patients were enrolled in this prospective, single-center study. The cataract patients underwent phacoemulsification with bilateral implantation of a TECNIS Symfony (Abbott Medical Optics, Santa Ana, CA, USA, 15 patients) or a TECNIS Monofocal ZCB00 (Abbott Medical Optics, Santa Ana, CA, USA, 15 patients). Postoperative evaluations were performed after 1 and 3 months, including visual acuities at far, intermediate, and near distance. Mesopic, scotopic vision, and contrast sensitivity were investigated. Aberrometry was performed using an iTrace aberrometer with a pupil scan size of 5.0 mm.
After 3 months, the TECNIS Symfony group reached an uncorrected visual acuity at far distance of -0.02 logMAR compared to -0.06 logMAR in the TECNIS Monofocal group ( p = 0.03). Regarding the uncorrected vision at intermediate and near distance the following values were obtained: intermediate visual acuity -0.13 versus 0.0 logMAR (TECNIS Symfony vs TECNIS Monofocal, p = 0.001) and near visual acuity 0.11 versus 0.26 logMAR (TECNIS Symfony vs TECNIS Monofocal, p = 0.001). Low-contrast visual acuities were 0.27 versus 0.20 logMar (TECNIS Symfony vs TECNIS Monofocal, p = 0.023).
The TECNIS Symfony intraocular lens can be considered an appropriate alternative to multifocal intraocular lenses because of good visual results at far, intermediate, and near distance as well as in low-contrast vision.
本研究旨在评估与单焦点人工晶状体相比，双侧植入扩展焦深人工晶状体后的临床效果。
德国柏林夏里特医科大学眼科。
本前瞻性单中心研究共纳入30例患者的60只眼。白内障患者接受了双侧植入TECNIS Symfony（美国雅培医疗光学公司，加利福尼亚州圣安娜，15例患者）或TECNIS单焦点ZCB00（美国雅培医疗光学公司，加利福尼亚州圣安娜，15例患者）的超声乳化手术。术后1个月和3个月进行评估，包括远、中、近距离视力。研究了中间视觉、暗视觉和对比敏感度。使用瞳孔扫描尺寸为5.0 mm的iTrace像差仪进行像差测量。
3个月后，TECNIS Symfony组的远距未矫正视力为-0.02 logMAR，而TECNIS单焦点组为-0.06 logMAR（p = 0.03）。关于中、近距离的未矫正视力，得到以下数值：中距离视力-0.13对0.0 logMAR（TECNIS Symfony对TECNIS单焦点，p = 0.001），近距离视力0.11对0.26 logMAR（TECNIS Symfony对TECNIS单焦点，p = 0.001）。低对比度视力为0.27对0.20 logMar（TECNIS Symfony对TECNIS单焦点，p = 0.023）。
由于TECNIS Symfony人工晶状体在远、中、近距离以及低对比度视力方面都有良好的视觉效果，因此可被视为多焦点人工晶状体的合适替代品。
