Photic phenomena
Visual disturbances such as halos, glare, or starbursts experienced by patients after refractive or cataract surgery.
Full Definition
Photic phenomena encompass various visual symptoms including halos, glare, starbursts, and light sensitivity that patients may experience following ocular surgery, particularly after multifocal IOL implantation or refractive procedures. These symptoms typically occur under specific lighting conditions, such as night driving or bright ambient light. Documentation should characterize the type, severity, and circumstances of photic phenomena, as they may indicate optical aberrations, residual refractive error, or IOL-related issues. Patient education regarding expected versus concerning symptoms is crucial for proper postoperative management and revision decision-making.
Usage
Usage note: Document specific types of photic phenomena and their impact on daily activities.
