Anterior Segment Anatomy Assessed by Swept-Source OCT in Ocular Surgery Patients

Inclusion Criteria: * Voluntary provision of written informed consent. * 18≤Age≤90 years. * Patients diagnosed by an ophthalmologist with cataract, primary angle-closure disease, or other anterior segment disorders requiring anterior segment surgery. * Availability of complete or accessible preoperative and postoperative clinical records and ophthalmic examination data. Exclusion Criteria: * Follow-up duration of less than 3 months. * Substantial missing ophthalmic examination or perioperative data that prevents the required study analyses. * Inability to obtain valid anterior segment imaging data due to severe corneal opacity, poor ocular fixation, inadequate cooperation, or other related factors. * Presence of severe ocular trauma, intraocular tumors, severe corneal disease, active intraocular inflammation, or other ocular conditions that may substantially affect anterior segment structural assessment. * History of complex intraocular surgery that may significantly alter anterior segment anatomy and is considered unsuitable for inclusion by the investigator. * Other conditions considered by the investigator to make the patient unsuitable for participation in the study.
