摘　　要：目的:研究1.8mm微切口超声乳化白内障摘除术植入博士伦四点支撑板状襻Akreos MI60人工晶状体眼的伪调节力。方法:回顾性系列病例研究。选取我院单纯年龄相关性白内障行1.8mm微切口超声乳化联合博士伦Akreos MI60人工晶状体植入术的患者19例22眼,在术后6mo进行随访,观察其远视力、最佳矫正远视力,35cm近视力、最佳矫正近视力;离焦法测定人工晶状体眼伪调节力(主观法);在药物(20g/L毛果芸香碱)诱导下用UBM测量前房深度的变化并计算其伪调节力(客观法)。结果:术后6mo,裸眼远视力为0.81±0.11,最佳矫正远视力为0.91±0.09;35cm近视力为0.62±0.10,最佳矫正近视力为0.85±0.11;调节幅度离焦法测定人工晶状体眼伪调节力为2.55±0.24D,前房深度测量法(ACD法)为0.72±0.13D。结论:对于没有明显屈光不正的患者,博士伦AkreosMI60人工晶状体眼术后早期具有一定的伪调节力,主观法测得调节幅度大于客观法。AIM： To study the pseudo - accommodation in pseudophakic eyes after the surgery of coaxial 1. 8mm microincision phacoemulsiflcation and implantation of Akreos MI60 intraocular lens （IOL）. METHODS： In the retrospective study, 22 eyes of 19 patients[ mean age 63.77 years ± 2.98（SD） （range 60 to 69 years）] had phacoemulsification and Akreos MI60 IOL implantation. After 3 to 6 months, far and near vision and the best corrected vision were examined. Pseudophakic accommodation was also measured by subjective techniques （defocus） and objective techniques E change in the anterior chamber depth （ACD） before and after using pilocarpine 20g/L eye dropsy. RESULTS： After 3 to 6 months, the mean far vision was 0.81＋_0.11, the mean best corrected far vision was 0.91 ± 0.09; the mean near vision was 0.62±0.10, the mean best corrected near vision was 0. 85 ± 0. 11; the mean accommodative range was （2.55± 0.24） D by subjective techniques and （0.72±0.13） D by objective techniques. CONCLUSION： The pseudophakic eyes implanted with Akreos MI60 possess pseudophakic have accommodation in the early days. The accommodative range measured by subjective techniques is bigger than by objective techniques.
