目的：应用眼压描记法观察白内障超声乳化术对房水流畅系数的影响。

方法：选取2018-01/10在我院接受白内障超声乳化联合人工晶状体植入术的年龄相关性白内障患者126例126眼，手术前后采用非接触眼压计测量眼压，采用Schiotz电子眼压计测量房水流畅系数。

结果：术后1d本组患者眼压(19.01±1.81mmHg)较术前(17.09±1.70mmHg)升高，但术后1wk，1、3mo眼压均较术前降低(P<0.05)； 术后1wk，1、3mo房水流畅系数(0.20±0.01、0.22±0.02、0.22±0.02)均较术前(0.19±0.02)明显改善(P<0.05)。

结论：白内障超声乳化术会增加房水流畅系数，这可能与术后眼压降低有关。

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(P<0.05). The coefficient of outflow facility 1wk, 1mo and 3mo after the operation(0.20±0.01, 0.22±0.02, 0.22±0.02)at all postoperative visits has obviously improved before the operation(0.19±0.02; P<0.05).

CONCLUSION:Phacoemulsifcation increases the coefficient of outflow facility and this partially accounts for the IOP reduction after cataract surgery with phacoemulsifcation and IOL implantation.
