About this study
Official title: Economic Analysis for Office-Based Versus Ambulatory Surgery Center-Based Cataract Surgery
To analyze the economics of office-based (OBS) versus ambulatory surgery center (ASC)-based cataract surgery.
Read the detailed description
This study was conducted as a randomized, controlled clinical trial at a single private practice institution. Patients presenting for routine cataract surgery scheduling were randomized prospectively to undergo the procedure in either the OBS or ASC-based setting. The primary outcome was total average cost for performing OBS versus ASC-based cataract surgery. The secondary outcome was total average facility reimbursement for OBS versus ASC-based cataract surgery.
