specific to that field. This may include a one-year integrated internship that involves more general medical training in other fields such as internal medicine or general surgery. Following residency, additional specialty training (or fellowship) may be sought in a particular aspect of eye pathology.
Ophthalmologists prescribe medications to treat eye diseases, implement laser therapy, and perform surgery when needed. Ophthalmologists provide both primary and specialty eye care - medical and surgical. Most ophthalmologists participate in academic research on eye diseases at some point in their training and many include research as part of their career.
Ophthalmology has always been at the forefront of medical research with a long history of advancement and innovation in eye care.

roots of the word ophthalmology are ὀφθαλμός (, "eye") and -λoγία (-, "study, discourse"), i.e., "the study of eyes". The discipline applies to all animal eyes, whether human or not, since the practice and procedures are quite similar with respect to disease processes, although there are differences in the anatomy or disease prevalence.

advanced such ideas with empiricism. He dissected the eyes of animals, and discovering three layers (not two), found that the fluid was of a constant consistency with the lens forming (or congealing) after death, and the surrounding layers were seen to be juxtaposed. He and his contemporaries further put forth the existence of three tubes leading from the eye, not one. One tube from each eye met within the skull.

Rufus of Ephesus ( el, Ῥοῦφος ὁ Ἐφέσιος, fl. late 1st and early 2nd centuries AD) was a Greek physician and author who wrote treatises on dietetics, pathology, anatomy, gynaecology, and patient care. He was an admirer of Hip ...

There is only one professional organization in the country that is duly recognized by the PMA and the PCS: the Philippine Academy of Ophthalmology (PAO). PAO and the state-standard Philippine Board of Ophthalmology (PBO) regulates ophthalmology residency programs and board certification. To become a general ophthalmologist in the Philippines, a candidate must have completed a doctor of medicine degree (MD) or its equivalent (e.g. MBBS), have completed an internship in Medicine, have passed the physician licensure exam, and have completed residency training at a hospital accredited by the Philippine Board of Ophthalmology (accrediting arm of PAO). Attainment of board certification in ophthalmology from the PBO is essential in acquiring privileges in most major health institutions. Graduates of residency programs can receive further training in ophthalmology subspecialties, such as neuro-ophthalmology, retina, etc. by completing a fellowship program that varies in length depending on each program's requirements.

Ophthalmologists typically complete four years of undergraduate studies, four years of medical school and four years of eye-specific training (residency). Some pursue additional training, known as a fellowship - typically one to two years. Ophthalmologists are physicians who specialize in the eye and related structures. They perform medical and surgical eye care and may also write prescriptions for corrective lenses. They often manage late stage eye disease, which typically involves surgery.
Ophthalmologists must complete the requirements of continuing medical education to maintain licensure and for recertification.
