Effect of phacoemulsification on the flow coefficient of aqueous humor

Abstract

AIM:To explore the effect of phacoemulsification on the fluency coefficient of aqueous humor through the application of tonography. METHODS:Participants in this study were patients who underwent standard clear corneal incision phacoemulsifcation with intraocular lens(IOL)implantation in our hospital from January to October in 2018. Intraocular pressure(IOP)was measured through non-contact tonometer 1d, 1wk, 1mo and 3mo before and after the operation. The fluency coefficient of aqueous humor was measured using electronic Schiotz tonography 1wk, 1mo and 3mo before and after the operation.RESULTS:IOP was higher than baseline(17.09±1.70mmHg)on the first day after operation(19.01±1.81mmHg), and the average IOP at other times was lower than baseline(PPCONCLUSION:Phacoemulsifcation increases the coefficient of outflow facility and this partially accounts for the IOP reduction after cataract surgery with phacoemulsifcation and IOL implantation.
