We report 3 cases of a torn haptic after successful scleral fixation with a hydrophobic acrylic intraocular lens.
Patients complained of decreased visual acuity about 1 week to 1 month after scleral fixation.
In all 3 cases, the direction of the damaged haptic correlated with the direction of the pulling force made by the hung suture material. Observation of a cheese-wiring effect on scanning electron microscopy suggested that the haptic was cut by the suture.
Patients underwent re-scleral fixation with caution.
There was no complication of broken haptic after re-scleral fixation.
To avoid unexpected haptic tears, great caution is needed; surgeons should avoid applying excessive pulling force to the intraocular lens when performing scleral fixation using a hydrophobic acrylic intraocular lens.
我们报告3例在使用疏水丙烯酸人工晶状体成功进行巩膜固定后发生襻撕裂的病例。
患者在巩膜固定术后约1周 至1个月抱怨视力下降。
在所有3例病例中，受损襻的方向与悬挂缝线材料产生的拉力方向相关。扫描电子显微镜观察到的奶酪样拉丝效应提示襻被缝线切断。
患者谨慎地接受了再次巩膜固定。
再次巩膜固定后未出现襻断裂的并发症。
为避免意外的襻撕裂，需要格外小心；外科医生在使用疏水丙烯酸人工晶状体进行巩膜固定时，应避免对人工晶状体施加过大的拉力。
