Ocular Biometric Parameters of Acute Primary Angle Closure with Varying Degrees of Lens Zonular Laxity

This study introduces a novel stratification of APAC patients by zonular laxity severity and reveals distinct biometric profiles across subgroups. We demonstrate a high prevalence of undiagnosed zonulopathy in APAC patients, associated with thicker lenses and shallower anterior chambers. A key limitation is the subjective classification of zonular laxity, based solely on intraoperative observations. Future studies should develop objective imaging protocols for improved detection and management.
