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.
