Patients were examined postoperatively on day 1, week 1 and week 6. Indentation gonioscopy and AS\u2010OCT<\/jats:styled-content> were performed preoperatively and at 6 weeks after surgery.<\/jats:p><\/jats:sec>Main Outcome Measures<\/jats:title>Angle and anterior segment parameters by AS\u2010OCT<\/jats:styled-content> and amount of peripheral anterior synechiae (PAS<\/jats:styled-content>) by gonioscopy.<\/jats:p><\/jats:sec>Results<\/jats:title>Sixty\u2010five eyes of 55 patients completed the trial. The mean extent of PAS<\/jats:styled-content> was significantly reduced from 127.7 to 95.0 degrees (P<\/jats:styled-content><\/jats:italic>\u2009<\u20090.001) by Phaco alone, and from 174.0 to 77.3 degrees (P<\/jats:styled-content><\/jats:italic>\u2009<\u20090.001) by Phaco\u2010VGP<\/jats:styled-content>. Phaco\u2010VGP<\/jats:styled-content> resulted in significantly greater reduction in PAS<\/jats:styled-content> extent (P<\/jats:styled-content><\/jats:italic>\u2009=\u20090.002). Angle\u2010opening distance and trabecular\u2010iris space\u2010area measured by AS\u2010OCT<\/jats:styled-content> increased significantly after Phaco alone and Phaco\u2010VGP<\/jats:styled-content> (P<\/jats:styled-content><\/jats:italic>\u2009<\u20090.001 for both). Although the change was higher in the Phaco\u2010VGP<\/jats:styled-content> group, this did not reach statistical significance. Anterior chamber depth (ACD<\/jats:styled-content>) increased, and lens vault (LV<\/jats:styled-content>) decreased after both procedures. The amount of change in ACD<\/jats:styled-content> and LV<\/jats:styled-content> was not significant between the two groups.<\/jats:p><\/jats:sec>Conclusion<\/jats:title>\u2002Both Phaco alone and Phaco\u2010VGP<\/jats:styled-content> resulted in widening of the drainage angle, deepening of the anterior chamber and reduction of intraocular pressure (IOP<\/jats:styled-content>) and PAS<\/jats:styled-content> extent in PACG<\/jats:styled-content> eyes. Phaco\u2010VGP<\/jats:styled-content> resulted in significantly more reduction of PAS<\/jats:styled-content>.
