Cataract surgery improves anterior segment parameters in acute primary angle closure eyes

Cataract extraction surgery significantly improves anterior segment parameters, such as anterior chamber depth and volume, in patients with acute primary angle closure (APAC) and fellow primary angle closure suspect (PACS) eyes, according to a study.

In the study, researchers assessed various anterior segment parameters, including anterior chamber depth (ACD), anterior chamber volume (ACV), and intraocular pressure (IOP), in 60 eyes from 30 patients before and after surgery.

There were significant improvements in both APAC and PACS eyes postoperatively, with marked increases in ACD and ACV. The lens vault and iridocorneal angle contact index also showed significant decreases after the procedure. Eyes with APAC experienced a significant reduction in IOP and enhanced visual acuity at multiple follow-up points, while the PACS eyes maintained normal IOP levels and displayed improvements in VA by the first week and final follow-up.

The findings suggest that lens extraction surgery effectively alleviates anterior segment crowding in both APAC and PACS eyes.
