AIM: To investigate the effect of phacoemulsification combined with intraocular lens implantation on anterior chamber depth and chamber angle width and so on.

METHODS: A total of 74 cases(89 eyes)with cataract phacoemulsification combined with intraocular lens implantation were selected from Jun. 2015 to May. 2016 in our hospital, measured preoperative and postoperative 3mo intraocular pressure, central anterior chamber depth(ACD), angle open distance(AOD500)and anterior chamber angle(ACA500).

RESULTS: Patients postoperative 3mo the intraocular pressure was 11.34±2.38mmHg, which was lower than that preoperative(P<0.05). Patients postoperative 3mo ACD was 4.01±0.30mm, was significantly thicker than preoperative(P<0.05). Patients postoperative 3mo AOD500 and ACA500 were 0.915±0.223 mm and 41.71°±6.55°, were significantly higher than preoperative, the difference was statistically significant(P<0.05). Intraocular pressure was negatively correlated with ACD, AOD500 and ACA500(r=-0.239, -0.211 and -0.252, P<0.05).

CONCLUSION: Phacoemulsification combined with intraocular lens implantation can reduce the intraocular pressure, increase the depth of anterior chamber and the width of chamber angle, so as to play a positive role inaqueous humor circulation.
