Releasing aqueous humor of anterior chamber to treat early elevated lOP after lCL implantation / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

To explore the effect of releasing aqueous humor of anterior chamber through lateral incision of cornea in treating early elevated intraocular pressure ( lOP ) after implantation of implantable collamer lens ( lCL) .METHODS: Patients with elevated lOP were analyzed after lCL implantation. When the lOP>25mmHg, aqueous humor was released slowly through lateral incision of cornea, and made the lOP reduce to 10 ~13mmHg. After operation, lOP was measured every 2h. The releasing of aqueous humor was repeated until the lOP was decreased to normal.RESULTS: One hundred sixty - seven patients ( 330 eyes) were implanted lCL, while the lOP of 32 patients (62 eyes) was higher than 25mmHg after lCL implantation. Viscoelastic material was found in aqueous humor of most of high lOP patients, and the lOP of 48 eyes did not increase again through releasing aqueous humor once. The lOP 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.CONCLUSlONThe main reason of early elevated lOP after lCL implantation is the remaining of viscoelastic material of eyes. Releasing aqueous humor through lateral incision of cornea can decrease lOP effectively. lt is a simple, safe, painless and repetition, which the patients are willing to accept.
