To compare differences in high-order aberrations between 2 intraocular lenses (IOLs), the Hydroview H60M (Bausch & Lomb) and AcrySof MA30BA (Alcon).
Department of Ophthalmology, Nara Medical University, Nara, Japan.
Twenty-four eyes of 14 patients with a Hydroview IOL and 25 eyes of 20 patients with an AcrySof IOL who had uneventful phacoemulsification and a best corrected visual acuity better than 20/16 from 6 to 12 months after surgery were evaluated. High-order aberrations were measured using a Hartmann-Shack aberrometer at 4.0 mm and 6.0 mm wavefront aperture diameters, and IOL tilt and decentration were assessed by Scheimpflug videophotography.
There were no differences between the 2 groups in IOL tilt and decentration (P>.05, Mann-Whitney U test). In the cornea, there were no differences between the 2 groups in high-order aberrations at 4.0 mm and 6.0 mm aperture diameters (P>.05, Mann-Whitney U test). In the whole eye, there was a significant difference between Hydroview (mean 0.441 microm +/- 0.147 [SD]) and AcrySof (0.696 +/- 0.287 microm) IOLs in spherical-like aberrations at the 6.0 mm aperture diameter (P =.00008, Mann-Whitney U test); there were no differences between the 2 groups in other aberrations.
The type of IOLs influenced spherical-like aberrations. The IOL's shape was a particularly important factor in spherical-like aberrations. The aberrations may affect night driving in certain individuals.
比较两种人工晶状体(IOL),即HydrView H60M(博士伦公司)和AcrySof MA30BA(爱尔康公司)之间高阶像差的差异。
日本奈良医科大学眼科。
对14例植入HydrView人工晶状体的患者的24只眼和20例植入AcrySof人工晶状体的患者的25只眼进行评估,这些患者均接受了顺利的白内障超声乳化手术,且术后6至12个月最佳矫正视力优于20/16。使用Hartmann-Shack像差仪在4.0毫米和6.0毫米波前孔径直径下测量高阶像差,并通过Scheimpflug视频摄影评估人工晶状体的倾斜和偏心。
两组人工晶状体的倾斜和偏心无差异(P>0.05,Mann-Whitney U检验)。在角膜方面,两组在4.0毫米和6.0毫米孔径直径下的高阶像差无差异(P>0.05,Mann-Whitney U检验)。在全眼方面,HydrView(平均0.441微米±0.147[标准差])和AcrySof(0.696±0.287微米)人工晶状体在6.0毫米孔径直径下的类球差有显著差异(P = 0.00008,Mann-Whitney U检验);两组在其他像差方面无差异。
人工晶状体的类型影响类球差。人工晶状体的形状是类球差的一个特别重要的因素。这些像差可能会影响某些个体的夜间驾驶。
