Inclusion criteria

Inclusion criteria: Group 1: performed on patients who underwent cataract surgery at Ewha Womans University Mokdong Hospital with a history of acute angle-closure attack, from January 2012 to July 2021, and who had medical records for the follow-up period from 1 month to 3 months after surgery. The acute angle-closure attack was defined as when anterior angle obstruction of 180 degrees or more was accompanied by an increase in intraocular pressure, along with symptoms such as headache, visual dimness, and eye pain. Group 2: Among patients who underwent cataract surgery at Ewha Womans University Mokdong Hospital from January 2012 to July 2021, patients with no underlying ophthalmic history other than cataracts were included.

Exclusion criteria

Exclusion criteria: Patients with ophthalmological diseases such as neovascular glaucoma, uveitic glaucoma, other retinal or corneal diseases, patients with a history of ocular trauma, or other ophthalmic surgeries such as refractive surgery or vitrectomy were excluded.
