我们观察到眼内压（IOP）反复快速升高，认为是由植入IOL的患者的袋内眼内透镜（IOL）不稳定引起的。由于11月8日左眼出现急性青光眼发作样IOP升高，她被收住和歌山医科大学医院。第一次检查的结果包括IOP为62 mm Hg、PMMA单件式IOL不稳定、浅前房、窄角、中度瞳孔散大和左眼瞳孔光反应丧失。11月15日，在60分钟暗室俯卧激发试验期间观察到IOP升高6 mm Hg。第一次检查后，患者感觉左眼疼痛，视力下降，紧急到我院就诊两次。尽管瞳孔缩小，但通过仰卧位休息实现了前房深度和IOP的正常化以及房角的增宽。这些事件被认为是由IOL的不稳定和前移引起的。2018年1月17日，对袋内IOL进行缝线固定。人工晶状体通过双侧支撑部经巩膜固定在巩膜上。手术治疗后1年内未观察到突发性眼痛复发、囊内IOL不稳定和IOP升高。袋内IOL的不稳定性导致反复急性闭角型青光眼样发作。采用人工晶状体襻固定于巩膜的方法，效果良好。
We observed repeated episodes of rapid increases in intraocular pressure (IOP) considered to be caused by an in-the-bag intraocular lens (IOL) instability in a patient with an implanted IOL. As acute glaucoma attack-like increase in IOP was noted in the left eye on November 8, she was admitted to Wakayama Medical University Hospital. The findings at the first examination included an IOP of 62 mm Hg, instability of a PMMA one-piece IOL, shallow anterior chamber, narrow angle, moderate mydriasis, and loss of pupillary light reaction in the left avitreous eye. On November 15, a 6-mm Hg increase in IOP was observed during 60-min dark room prone provocative testing. After the first examination, the patient perceived pain and reduced visual acuity of the left eye and emergently consulted our hospital twice. Despite miosis, normalization of the anterior chamber depth and IOP with widening of the angle were achieved by resting in the supine position. These episodes were thought to be caused by instability and anterior shift of the IOL. On January 17, 2018, suture fixation of the in-the-bag IOL was performed. The IOL was fixed by transscleral suturing of the bilateral supporting parts to the sclera. Recurrence of sudden ophthalmalgia, instability of the in-the-bag IOL, and an increase in IOP have not been observed for 1 year after surgical treatment. Instability of an in-the-bag IOL caused repeated acute angle-closure glaucoma-like attacks. The situation was well treated by suturing and fixing the haptics of IOL to the sclera.
