Clinical observation of phacoemulsification and IOL combined with goniosynechialysis for age-related cataract merging with PACG

Abstract:

AIM: To investigate the curative effect of phacoemulsification and intraocular lens(IOL)implantation combined with goniosynechialysis in the treatment of age-related cataract merging with primary angle-closure glaucoma(PACG).

METHODS: Totally 80 patients with age-related cataract merging with PACG were in our hospital from January 2014 to January 2016. The preoperative average intraocular pressure(IOP)was 33.22±3.17mmHg; the average depth of anterior chamber was 2.07±0.15mm; the dynamic situation of primary angle closure ≤1/2 cycle by gonioscope. They were randomly divided into Group A and B for doing a study. All the two groups were treated with phacoemulsification and intraocular lens implantation. And the Group A was with goniosynechialysis. The following up period was 2mo, and we observed the IOP, chamber depth and the anterior chamber angle.

RESULTS: The change of chamber depth and intraocular pressure about the two groups: the average intraocular pressure of the Group A was 15.11±3.67mmHg,the chamber depth was 3.11±0.08mm; those of the Group B were 17.24±1.67mmHg, 2.76±0.15mm respectively; the differences had statistical significance(P<0.05). Postoperatively, there were 28 eyes(70%)in Group A with fully open anterior chamber angle, and 18 eyes(45%)in Group B(P<0.05).

CONCLUSION: The phacoemulsification and intraocular lens implantation combined with goniosynechialysis in the treatment of age-related cataract merging with primary angle-dosure glaucoma is safe and reliable. It's simple to operate, and do not increase the risk of surgery.
