35 patients were examined for their pseudoaccommodation 6 to 18 months after cataract extraction and implantation of a diffractive multifocal intraocular lens (MIOL). While in 15 patients a MIOL had been implanted in both eyes 20 patients had a MIOL in one eye only. 45 type 3M 815 LE and 5 3M 825 XE lenses were implanted. The mean age was 58.2 years +/- 9.6 years (33 to 76). Only patients without any pathology except cataract and preoperative refractive errors < +/- 5 diopters of spherical and +/- 1 diopter of astigmatic refraction were eligible for implantation of MIOLs. After estimation of the objective and subjective refraction the patients' pseudoaccommodation was measured by testing their visual acuity, adding lenses of +/- 1, 2, 3, 4, 5 diopters to their best distance correction. All patients with MIOLs reached a visual acuity of 0.4 or better with a maximum peak at 0 and -3 diopters. The visual acuity of the MIOL patients was significantly better in the range of -1 to -4 diopters compared to the results of a control group of patients with monofocal IOLs. This suggests a wider range of pseudoaccommodation in patients with MIOLs.
35例患者在白内障摘除并植入衍射多焦点人工晶状体（MIOL）后6至18个月接受了假调节检查。其中15例患者双眼植入了MIOL，20例患者仅单眼植入了MIOL。共植入了45枚3M 815 LE型和5枚3M 825 XE型晶状体。平均年龄为58.2岁±9.6岁（33至76岁）。仅白内障且术前球镜屈光不正<±5屈光度、散光屈光不正<±1屈光度，无其他任何病变的患者符合MIOL植入条件。在评估客观和主观屈光之后，通过测试患者视力，在其最佳远距矫正基础上增加±1、2、3、4、5屈光度的镜片来测量患者的假调节。所有植入MIOL的患者视力均达到0.4或更好，在0和-3屈光度时达到最大峰值。与单焦点人工晶状体对照组的结果相比，MIOL患者在-1至-4屈光度范围内的视力明显更好。这表明MIOL患者的假调节范围更广。
