PRCIS: The combination of phacoemulsification, goniosynechialysis and goniotomy is an effective treatment for primary angle closure glaucoma patients with cataract, and this is not linked to the extent of preoperative peripheral anterior synechiae. PURPOSE: To evaluate the impact of the extent of peripheral anterior synechiae (PAS) on the effectiveness and safety of combined phacoemulsification (PEI), goniosynechialysis (GSL), and goniotomy (GT) in eyes with primary angle closure glaucoma (PACG) and cataract. PATIENTS AND METHODS: This study included patients diagnosed with PACG and cataracts who underwent combined PEI and 120 degrees GSL plus GT (PEI+GSL+GT) between April 2020 and October 2022 at 10 ophthalmic institutes. Eligible patients were divided into 3 groups based on the extent of PAS: 180°≤PAS<270°, 270°≤PAS<360°, and PAS=360°. Data on intraocular pressure (IOP), the number of ocular hypotensive medications, and complications were collected and compared. The study defined complete success as postoperative IOP within the 6-18 mm Hg range and a 20% reduction from baseline without the use of topical medications. Qualified success was defined in the same way as complete success, but it allowed for the use of ocular hypotensive medications. RESULTS: Three hundred four eyes of 283 patients were included. The mean follow-up was 12.50±1.24 months. All groups experienced a significant reduction in IOP after the surgery ( P <0.05). There were no significant differences in final IOP, number of medications, and cumulative complete and qualified success rates among the 3 groups ( P >0.05). The groups with 270°≤PAS<360°had a higher frequency of hyphema compared with 180°≤PAS<270° ( P = 0.044). CONCLUSIONS: PEI+GSL+GT has proven to be an effective treatment for PACG with cataracts over a 1 year period. However, the outcome was not correlated with the preoperative extent of PAS.
