Preoperative Factors Associated with IOP Reduction After Cataract Surgery

Abstract

Preoperative IOP was the only factor significantly associated with postoperative IOP reduction after cataract surgery in POAG patients. A higher preoperative IOP was strongly associated with a greater postoperative IOP reduction. Patients with low preoperative IOPs tended to have minimal reduction or even a mild increase in postoperative IOPs. These findings have important implications when considering combined cataract extraction and filtration surgery for POAG patients.
