目的：探讨前房放液法在有晶状体眼后房型人工晶状体植入术(implantable collamer lens，ICL)术后早期眼压升高治疗中的应用。
方法：ICL植入术后早期高眼压患者，眼压>25mmHg时，表面麻醉下，用一次性注射器针尖从角膜侧切口缓慢将房水放出，使眼压降至10～13mmHg。术后每2h测量眼压，如眼压再次升高，可反复放房水处理，直至眼压正常。
结果：ICL植入术患者167例330眼，术后眼压>25mmHg者32例62眼，其中部分房水可见黏弹剂。大多数患眼(48眼)通过1次放液治疗成功无复发。经过最多3次侧切口放液，所有患眼眼压均恢复正常。术后随访未见异常。
结论：黏弹剂残留是导致ICL植入术后早期眼压升高的主要原因，侧切口前房放液法能有效、及时降低眼压。操作简单、安全、无痛，患者乐于接受，可反复进行。

AIM: To explore the effect of releasing aqueous humor of anterior chamber through lateral incision of cornea in treating early elevated intraocular pressure(IOP)after implantation of implantable collamer lens(ICL).
METHODS: Patients with elevated IOP were analyzed after ICL implantation. When the IOP>25mmHg, aqueous humor was released slowly through lateral incision of cornea, and made the IOP reduce to 10～13mmHg. After operation, IOP was measured every 2h. The releasing of aqueous humor was repeated until the IOP was decreased to normal.
RESULTS: One hundred sixty-seven patients(330 eyes)were implanted ICL, while the IOP of 32 patients(62 eyes)was higher than 25mmHg after ICL implantation.Viscoelastic material was found in aqueous humor of most of high IOP patients, and the IOP of 48 eyes did not increase again through releasing aqueous humor once. The IOP of all these eyes was decreased to normal through releasing aqueous humor in 3 times at most. There were no abnormal in postoperative follow-up.
CONCLUSION:The main reason of early elevated IOP after ICL implantation is the remaining of viscoelastic material of eyes. Releasing aqueous humor through lateral incision of cornea can decrease IOP effectively. It is a simple, safe, painless and repetition, which the patients are willing to accept.
