Abstract：
BACKGROUND: Ultrasound cycloplasty is a noninvasive surgery used to reduce intraocular pressure in patients with glaucoma, with fewer severe complications. This report presents several cases of iris neovascularization and neurotrophic keratopathy following ultrasound cycloplasty.
METHODS: Six patients diagnosed with refractory glaucoma underwent ultrasound cycloplasty at our clinic. Three cases developed iris neovascularization at postoperative day 3, week 2 and week 4 respectively, with intraocular pressure ranging from 12 to 24 mmHg. The other three cases developed neurotrophic keratopathy at postoperative week 3, week 6 and week 8 which completely healed within 60 days.
CONCLUSIONS: Iris neovascularization and neurotrophic keratopathy can be triggered after ultrasound cycloplasty, which are uncommon and self-limited but potentially vision-threatening. Preoperative risk assessment and regular postoperative follow-up are recommended to manage complications effectively.

摘要：
背景：超声睫状体成形术是一种无创手术，用于降低青光眼患者的眼内压，减少严重并发症。本报告介绍了超声睫状体成形术后的几例虹膜新生血管形成和神经营养性角膜病变。
方法：6例诊断为难治性青光眼的患者在我们的诊所接受了超声睫状体成形术。3例患者分别于术后第3天、第2周和第4周出现虹膜新生血管,眼压范围从12到24mmHg。其他3例患者在术后第3周，第6周和第8周出现神经营养性角膜病变，并在60天内完全愈合。
结论：超声睫状体成形术后可引发虹膜新生血管和神经营养性角膜病变，这是不常见的，自我限制，但潜在的视力威胁。建议进行术前风险评估和术后定期随访，以有效控制并发症。
