The American Academy of Ophthalmology believes that the public’s interests are served when patients have access to primary eye care services that meet their needs for healthy eyes and best possible vision. Ophthalmologists are specifically trained to provide these services because their medical school education provides a thorough understanding of pathology and disease processes, systemic disorders with ocular manifestations, as well as skills and experience in medical decision-making. Primary eye care provides an entry point for patients to receive refractions and glasses or contact lenses, screenings for asymptomatic eye diseases, diagnosis and treatment of most eye conditions, referral to specialists, and coordination with other aspects of medical care. While it is the ophthalmologist’s responsibility to perform the comprehensive medical eye evaluation, certain aspects of data collection may be conducted by trained individuals under the supervision of the ophthalmologist.
