To evaluate CT Lucia 602 intraocular lenses implanted in cases lacking capsular support and explanted because of decentration/dislocation with subsequent pathological analysis. The main objectives were to (1) document the status of haptics and (2) verify the presence of the rotisserie effect.

Case series with clinicopathological correlation.
13 explanted CT Lucia 602 lenses were included: 12 implanted by the Yamane technique and 1 that was iris-fixated. 4 lenses were explanted between October 2020 and February 2022. 9 lenses, explanted between November 2022 and February 2024, also exhibited severe optic tilt, leading to explantation. A chart review was performed to obtain clinical information from each case. Explanted lenses underwent gross and microscopic examination for haptic status and rotation, in the dry state (room temperature) and after hydration (body temperature).
Time between implantation and explantation was longer for lenses explanted before November 2022 (without severe tilt). Among the 26 haptics evaluated, 15 were deformed, 6 were broken, 2 were detached, and 3 were unremarkable. 4 haptics of Yamane lenses explanted between November 2022 and February 2024 showed free rotation within the optic insertion, after hydration at body temperature.
Anecdotal reports of the rotisserie effect of CT Lucia 602 lenses implanted by the Yamane technique appeared mostly during the second half of 2022 and suggested that affected lenses were from specific batches, which seems to be consistent with the findings of this study.
评估因晶状体偏中心/脱位而被取出且缺乏囊袋支撑的病例中植入的CT Lucia 602人工晶状体，并进行后续病理分析。主要目的是：（1）记录襻的状态；（2）验证是否存在旋转效应。

具有临床病理相关性的病例系列研究。
纳入13枚被取出的CT Lucia 602人工晶状体：12枚采用山根技术植入，1枚为虹膜固定。4枚人工晶状体于2020年10月至2022年2月期间被取出。9枚于2022年11月至2024年2月期间被取出的人工晶状体也出现了严重的光学倾斜，导致被取出。进行病历回顾以获取每个病例的临床信息。对取出的人工晶状体在干燥状态（室温）和水化后（体温）进行大体和显微镜检查，以评估襻的状态和旋转情况。
2022年11月之前被取出的人工晶状体（无严重倾斜），植入与取出之间的时间更长。在评估的26个襻中，15个变形，6个断裂，2个脱离，3个无异常。2022年11月至2024年2月期间取出的山根人工晶状体的4个襻在体温水化后在光学插入处显示自由旋转。
关于采用山根技术植入的CT Lucia 602人工晶状体旋转效应的传闻大多出现在2022年下半年，表明受影响的人工晶状体来自特定批次，这似乎与本研究结果一致。
