To evaluate the efficacy and stability of haptic sutured in-the-bag intraocular lens (IOL) in eyes with zonular instability.
A total 60 eyes of 60 patients were included in this retrospective cohort study. Postoperative stability in three groups [haptic sutured IOL in the bag, IOL in the bag insertion with haptics oriented toward areas of zonulysis, IOL with capsular tension ring (CTR) in the bag insertion] were compared according to the IOL insertion methods. To evaluate the IOL stability, the changes of anterior chamber depth (ACD), refraction, contraction of anterior continuous curvilinear capsulotomy (CCC) area, and tilt of IOL were compared.
There was no significant difference in change of ACD (-0.04±0.01 mm in group of haptic sutured IOL, -0.07±0.01 mm in group of CTR insertion) and refraction (0.05±0.05 D in group of haptic sutured IOL, 0.37±015 D in group of CTR insertion) between the group of haptic sutured IOL in the bag and CTR insertion group. But in comparison of CCC contraction and IOL tilt, CTR insertion group showed less contraction (1.00%±0.52%) and less IOL tilt (2.66°±0.11°) than the group of haptic sutured IOL in the bag (6.32%±1.36%, 3.47°±0.11°, respectively). The CTR insertion group showed the least CCC contraction and the least tilt.
In eyes with zonular instability, the method of haptic sutured IOL in-the-bag shows comparable stability in ACD and refraction in comparison with IOL with CTR in the bag insertion. The method of IOL only in-the-bag insertion shows the largest contraction of CCC and the largest tilt of IOL.
评估在晶状体悬韧带不稳定的眼中，有触觉缝线的囊袋内人工晶状体（IOL）的有效性和稳定性。
本回顾性队列研究纳入了60例患者的60只眼。根据人工晶状体植入方法，比较了三组[囊袋内有触觉缝线的人工晶状体、触觉朝向晶状体悬韧带溶解区域的囊袋内人工晶状体植入、囊袋内植入带晶状体囊袋张力环（CTR）的人工晶状体]的术后稳定性。为评估人工晶状体的稳定性，比较了前房深度（ACD）、屈光、前连续环形撕囊（CCC）面积收缩以及人工晶状体倾斜度的变化。
囊袋内有触觉缝线的人工晶状体组与CTR植入组之间，ACD变化（囊袋内有触觉缝线的人工晶状体组为-0.04±0.01mm，CTR植入组为-0.07±0.01mm）和屈光（囊袋内有触觉缝线的人工晶状体组为0.05±0.05D，CTR植入组为0.37±0.15D）无显著差异。但在比较CCC收缩和人工晶状体倾斜度时，CTR植入组的收缩（1.00%±0.52%）和人工晶状体倾斜度（2.66°±0.11°）均小于囊袋内有触觉缝线的人工晶状体组（分别为6.32%±1.36%、3.47°±0.11°）。CTR植入组CCC收缩最小，倾斜度最小。
在晶状体悬韧带不稳定的眼中，囊袋内有触觉缝线的人工晶状体植入方法与囊袋内植入带CTR的人工晶状体相比，在ACD和屈光方面显示出相当的稳定性。仅囊袋内植入人工晶状体的方法显示CCC收缩最大，人工晶状体倾斜度最大。
