Objective   To evaluate the long-term effect of phacoemulsification (PHACO)+intraocular lens implantation (IOL) for cataract combined with primary angle closure (PAC) in the expansion phase.    Methods   Thirty-eight eyes of 29 patients which suffered from cataract combined PAC in the expansion phase had undergone PHACO+IOL and goniosynechialysis from June 2005 to December 2006 were retrospectively studied.    Results   A total of 32 eyes of 24 cases were followed up for 6 to 35 months post-operatively

meanly 19.53±8.93 months. The intraocular pressure (IOP) was significantly decreased from a preoperative mean of (31.61±9.88) mmHg without medication therapy to (16.73±2.13) mmHg in 1 month after operation and (15.61±1.94) mmHg at the end of follow-up. The differences between the untreatment and the treatment were statistically significant (P=0.000). The best corrected visual acuity (BCVA) was significantly improved in all cases (P=0.000). Although the BCVA at the end of follow-up was declined when compared with the acuity 1 month post-operatively

there was no significant difference. The mean central anterior chamber depth was increased from (2.22±0.51) mm preoperatively to (3.59±0.46) mm in 1 month after operation and (3.17±0.35) mm at the end of follow-up with significant differences (P=0.000). The angle of anterior chamber in all operated eyes became wider and the parts of angle closure opened at different degrees. All of patients had no any vision defection.    Conclusion   PHACO+IOL and combined with goniosynechialysis blocks primary angle-closure glaucoma course

and has better long-term effect.
