| 摘 要： | 目的：分析超声乳化人工晶状体植入后随时间推移，在眼内的前后位移度及其和屈光度变化的关系。方法：选择行白内障超声乳化联合单焦点一体式折叠人工晶状体植入术患者102例102眼，检测和分析术后人工晶状体在眼前节光学断层成像（ OCT ）图像中的位移表现，于术后1、3、6mo，2a分别记录前房深度变化值，远近视力及屈光度，并进行相关性分析。平均随访24±3．8 mo。结果：所选102眼术后1、3、6mo，2a远视力平均分别为0．78±0．13、0．75±0．14、0．72±0．12、0．72±0．10，近视力平均分别为0．38±0．12、0．41±0．13、0．46±0．12、0．47±0．10，患者术眼术后平均前房深度分别为3．75±0．16、3．69±0．13、3．61±0．12、3．62±0．11mm，患者术后屈光度分别为－0．47±0．26、－0．65±0．28、－0．93±0．24、－0．95±0．20 D。眼前节OCT图像显示白内障术后人工晶状体随时间推移向前移位，术后1、3、6 mo组间各数值两两比较均差异明显（P＜0．05），术后6mo和术后2a比较无明显差异。结论：白内障术后人工晶状体随时间推移向前移动，出现“视近漂移”，远视力降低，近视力增加，术后6 mo基本达稳定状态。 |

| Abstract: | AIM: To evaluate the relation between the position shift of intraocular lenses(IOL)and the change of refraction, after phacoemulcification with IOL implantation. METHODS: This study analyzed the anterior chamber depth, the change of the refraction, the distant vision and the near vision in 102 eyes of 102 patients at 1, 3, 6mo and 2a after phacoemulcification and monofocal one-piece foldable IOL implantation. The position shift of IOL detected by anterior segment optical coherence tomography(AS-OCT)was observed too. All of the patients were followed up for 24±3.8mo. RESULTS: The distant vision of the 102 eyes after cataract surgery and IOL implantation at 1, 3, 6mo and 2a were 0.78±0.13,0.75±0.14,0.72±0.12,0.72±0.10 respectively. The near vision were 0.38±0.12,0.41±0.13,0.46±0.12,0.47±0.10. The anterior chamber depth after surgerces were 3.75±0.16, 3.69±0.13, 3.61±0.12, 3.62±0.11mm. And the refractive degree was -0.47±0.26,-0.65±0.28,-0.93±0.24,-0.95±0.20. The position of the IOL was forward in the AS-OCT with time. The differences of the four indicators at 1, 3 and 6mo postoperatively were significant by multiple comparison(P<0.05),while the difference was not significant between those at 6mo and 2a. CONCLUSION: The movement of IOL in eyes after cataract surgery leads to the reduction of the distance vision and the increase of the near vision, which were stabilized at 6mo after surgeries. |
