To report five cases of structural weakness at the haptic-optic junction of the CT Lucia 602 intraocular lens (IOL) (Carl Zeiss Meditec Inc., Dublin, CA), including two optic breakages and three optic microfractures, while using the Yamane flanged intrascleral haptic fixation surgery (FIHFS).
A retrospective chart review of five cases that underwent Yamane FIHFS by the same surgeon between 2020 and 2022 was performed. Patients' demographics, operative technique, postoperative outcomes, and adverse events were recorded over a 12-month follow-up period.
One case of optic breakage, noted on postoperative week 1 (POW1), had the optic with the trailing haptic suspended in the vitreous while both haptic flanges remained secured to the sclera, requiring IOL exchange. The second case of optic breakage was noted intraoperatively and required explantation of the IOL with subsequent placement of an iris-fixated IOL. Three cases of optic microfractures were observed with no long-term complications. All five fractures occurred at the junction of the leading haptic.
Optic breakage and microfractures at the haptic-optic junction are unusual complications of intrascleral fixated IOL using the Yamane technique. To the best of our knowledge, this has not been previously reported with the CT Lucia 602 IOL. The authors recommend careful selection of the IOL material for this technique to prevent possible complications.
报告5例采用山根带凸缘巩膜内触觉固定术（FIHFS）时，CT Lucia 602人工晶状体（IOL）（卡尔蔡司医疗技术公司，加利福尼亚州都柏林）触觉-光学交界处出现结构薄弱的病例，包括2例光学部断裂和3例光学部微骨折。
对2020年至2022年间由同一位外科医生进行山根FIHFS的5例病例进行回顾性病历审查。在12个月的随访期内记录患者的人口统计学资料、手术技术、术后结果和不良事件。
1例在术后第1周（POW1）发现光学部断裂，光学部与 trailing触觉襻悬于玻璃体中，而两个触觉襻凸缘仍固定于巩膜，需要更换人工晶状体。第2例光学部断裂在术中发现，需要取出人工晶状体，随后植入虹膜固定人工晶状体。观察到3例光学部微骨折，无长期并发症。所有5处骨折均发生在leading触觉襻的交界处。
触觉-光学交界处的光学部断裂和微骨折是采用山根技术进行巩膜内固定人工晶状体的罕见并发症。据我们所知，此前CT Lucia 602人工晶状体尚未有此报道。作者建议为该技术仔细选择人工晶状体材料，以预防可能的并发症。
