AIM: To observe the changes of visual acuity, intraocular pressure(IOP)and anterior chamber structure after phacoemulsification intraocular lens(IOL)implantation and goniosynechialysis in acute angle-closure glaucoma with cataract.

METHODS: A prospective study. Totally 80 eyes with acute primary angle-closure glaucoma(APACG)and cataract were selected in our hospital from August 2019 to February 2021. All study underwent phacoemulsification IOL implantation and goniosynechialysis. Visual acuity, IOP, anterior chamber distance(ACD), trabecular iris angle(TIA)and angle opening distance(AOD500)were measured before and 1wk, 1, 3 and 6mo after surgery. Four quadrant angle classifications of upper, lower, nasal and temporal were determined by Scheie classification method and the measured values were statistically analyzed.

RESULTS: The postoperative corrected visual acuity in 1wk, 1, 3 and 6mo were improved than preoperative, there were no statistically significant differences between each postoperative period(P>0.05). The IOP in postoperative 1wk, 1, 3 and 6mo were reduced than preoperative, there were not significantly different between each postoperative period(P>0.05). The ACD in postoperative 1wk, 1, 3 and 6mo were deepen than preoperative, there were not significantly different between each postoperative period(P>0.05). The TIA in postoperative 1wk, 1, 3 and 6mo were widened than preoperative, there were not significantly different between each postoperative period(P>0.05). The AOD500 in postoperative 1wk, 1, 3 and 6mo were increased than preoperative, there were not significantly different between each postoperative period(P>0.05). The depth of anterior chamber angle in four quadrants were deepened combined with the depth in postoperative 1wk, 1, 3 and 6mo(P<0.05).

CONCLUSION: Phacoemulsification IOL implantation and goniosynechialysis in the treatment of acute angle-closure glaucoma with cataract can significantly improve visual acuity, increase the depth of central anterior chamber, open angle, reduce IOP. It is an effective and stable surgical method.
