Abstract

OBJECTIVE

To investigate the relationship between high frequency component of accommodative microfluctuation (HFC) and the pseudo accommodation after the implantation of foldable intraocular lenses (IOL).

METHODS

With ARK-730A accommodation analyzer we checked HFC in 50 cases (50 eyes) of patients who had good pupil reaction to light and the pupil diameter was 2.0 approximately 3.5 mm approximately. Three months after the implantation of foldable IOL, the relationship among ciliary muscle accommodative microfluctuation, IOL movement and pseudo accommodation was analyzed.

RESULTS

There was positive correlation between ciliary muscle accommodative microfluctuation and IOL movement (r = 0.702, P < 0.01), between IOL movement and pseudo accommodation (r = 0.861, P < 0.01), and between ciliary muscle accommodative microfluctuation and pseudo accommodation (r = 0.915, P < 0.01). Pseudo accommodation was greater in patients who showed more ciliary muscle accommodative microfluctuation and IOL movement.

CONCLUSION

HFC induces IOL movement, and it is one of the most important reasons for pseudo accommodation after foldable IOL implantation.

摘要

目的

探讨调节性微波动高频成分（HFC）与可折叠人工晶状体（IOL）植入术后假性调节之间的关系。

方法

使用ARK - 730A调节分析仪对50例（50眼）瞳孔对光反应良好且瞳孔直径约为2.0至3.5mm的患者进行HFC检查。在植入可折叠IOL三个月后，分析睫状肌调节性微波动、IOL运动和假性调节之间的关系。

结果

睫状肌调节性微波动与IOL运动之间存在正相关（r = 0.702，P < 0.01），IOL运动与假性调节之间存在正相关（r = 0.861，P < 0.01），睫状肌调节性微波动与假性调节之间存在正相关（r = 0.915，P < 0.01）。睫状肌调节性微波动和IOL运动较多的患者假性调节更大。
