摘要

This study investigated preoperative biometric measurements and perioperative complications of cataract surgery in eyes with shallow and non-shallow anterior chambers. This multicenter retrospective study included 1423 eyes of 1053 patients who underwent cataract surgery at five Japanese institutions between April 2016 and July 2023. Eyes with an anterior chamber depth (ACD) of ≤ 2.5 mm were classified as the shallow group; those with an ACD > 2.5 mm were categorized as the non-shallow group. The shallow group included older patients, more women, and better best-corrected visual acuity. Preoperative comorbidities, including retinitis pigmentosa, pseudoexfoliation syndrome, and a history of laser iridotomy or peripheral iridectomy, were more frequent in the shallow group. Intraoperatively, the eyes in the shallow group had higher rates of zonular dehiscence (ZD) (odds ratio [OR] 3.04; 95% confidence interval [CI] 1.32–6.94), use of a capsular tension ring (OR 3.52; 95% CI 1.54–8.07) or pupil expansion device (OR 2.17; 95% CI 1.20–3.85), and a higher incidence of postoperative corneal edema. In the shallow group, eyes with ZD had a smaller anterior lens radius of curvature and larger posterior lens radii of curvature. Lens curvature measurements may predict zonular instability in eyes with shallow anterior chambers.
