AIM: To study the effect of two kinds of phacoemulsification combined with goniosynechialysis for primary angle-closure glaucoma with cataract.

METHODS: Phacoemulsification combined with goniosynechialysis was performed in 60 patients 62 eyes for primary angle-closure glaucoma with cataract. They were randomly divided into two groups, 31 eyes underwent phacoemulsification with goniosynechialysis combined with I/A catheterization were performed in Group A; in Group B, 31 eyes were performed phacoemulsification with goniosynechialysis combined with viscoelastics. Best corrected visual acuity, the intraocular pressure, anterior chamber depth, anterior chamber angle width and pupil size were measured before the operation, and 3mo after the operation.

RESULTS: Intraocular pressure of all cases were reduced obviously after the operation(P<0.05). Visual acuity of the 62 eyes were improved in different extent; the anterior chamber depth and anterior chamber angle width after 3mo of the operation were deeper and wider than those before the operation(P<0.05). There were no different in the intraocular pressure, best corrected visual acuity and anterior chamber depth between the two groups(P>0.05), but, Group A was superior to Group B in anterior chamber angle width(P<0.05). At 3mo after operation, there were 8 eyes in Group A with more than 1mm lessen pupil size, two eyes in Group B had the same.

CONCLUSION: Two kinds of goniosynechialysis combined with phacoemulsification in the treatment of primary acute angle-closure glaucoma with cataract are effective. Among them, the goniosynechialysis with I/A was more effective to increase the anterior chamber angle width.
