  • The history of ophthalmology dates back to ancient times, with the first recorded eye surgery performed in ancient Egypt around 2500 BCE. The ancient Greeks also made significant contributions to the field, with Hippocrates and Galen both writing about eye diseases and treatments. In the Middle Ages, Arab physicians made advancements in ophthalmology, including the use of anesthesia during eye surgeries.

In the United States, the American Academy of Ophthalmology was founded in 1896, and the first residency program in ophthalmology was established in 1914 at Johns Hopkins University. In recent history, the field of ophthalmology has seen significant advancements in technology, including the development of laser eye surgery for vision correction and the use of intraocular lenses for cataract surgery. The use of telemedicine has also allowed for remote diagnosis and treatment of eye diseases. Additionally, research in genetics has led to a better understanding of inherited eye diseases and potential treatments. Overall, the field of ophthalmology continues to evolve and improve, providing better care for patients with eye diseases and disorders.
