Ophthalmology is a clinical and surgical specialty within medicine that deals with the diagnosis and treatment of eye disorders. A former term is oculism.
Myopia, also known as near-sightedness and short-sightedness, is an eye disease where light from distant objects focuses in front of, instead of on, the retina. As a result, distant objects appear blurry while close objects appear normal. Other symptoms may include headaches and eye strain. Severe myopia is associated with an increased risk of macular degeneration, retinal detachment, cataracts, and glaucoma.
Optometry is a specialized health care profession that involves examining the eyes and related structures for defects or abnormalities. Optometrists are health care professionals who typically provide comprehensive eye care.
Far-sightedness, also known as long-sightedness, hypermetropia, and hyperopia, is a condition of the eye where distant objects are seen clearly but near objects appear blurred. This blur is due to incoming light being focused behind, instead of on, the retina due to insufficient accommodation by the lens. Minor hypermetropia in young patients is usually corrected by their accommodation, without any defects in vision. But, due to this accommodative effort for distant vision, people may complain of eye strain during prolonged reading. If the hypermetropia is high, there will be defective vision for both distance and near. People may also experience accommodative dysfunction, binocular dysfunction, amblyopia, and strabismus. Newborns are almost invariably hypermetropic, but it gradually decreases as the newborn gets older.

The Southern College of Optometry is a privately owned educational institution located in Memphis, Tennessee. It specializes in optometry and offers a comprehensive program in this field.
Cataract surgery, also called lens replacement surgery, is the removal of the natural lens of the eye that has developed a cataract, an opaque or cloudy area. The eye's natural lens is usually replaced with an artificial intraocular lens (IOL) implant.
A-scan ultrasound biometry, commonly referred to as an A-scan, is a routine type of diagnostic test used in optometry or ophthalmology. The A-scan provides data on the length of the eye, which is a major determinant in common sight disorders. The most common use of the A-scan is to determine eye length for calculation of intraocular lens power. Briefly, the total refractive power of the emmetropic eye is approximately 60. Of this power, the cornea provides roughly 40 diopters, and the crystalline lens 20 diopters. When a cataract is removed, the lens is replaced by an artificial lens implant. By measuring both the length of the eye (A-scan) and the power of the cornea (keratometry), a simple formula can be used to calculate the power of the intraocular lens needed. There are several different formulas that can be used depending on the actual characteristics of the eye.
The Lions Eye Institute (LEI) is an Australian medical research institute affiliated with the University of Western Australia. It was established in 1983 with support of the Lions Clubs of Western Australia and headquartered in the Perth suburb of Nedlands, Western Australia. The LEI is a not-for-profit centre of excellence that combines an ophthalmic clinic with scientific discovery developing techniques for the prevention of blindness and the reduction of pain from blinding eye conditions.

The Illinois College of Optometry (ICO) is a private optometry college in Chicago, Illinois. Graduating approximately 160 optometrists a year, it is the largest optometry college in the United States and the oldest continually operating educational facility dedicated solely to the teaching of optometrists. The college complex incorporates more than 366,000 square feet (34,000 m2) including an on-site eye care clinic, electronically enhanced lecture center, library, computerized clinical learning equipment, cafeteria, fitness center, and living facilities.
Astigmatism is a type of refractive error due to rotational asymmetry in the eye's refractive power. This results in distorted or blurred vision at any distance. Other symptoms can include eyestrain, headaches, and trouble driving at night. Astigmatism often occurs at birth and can change or develop later in life. If it occurs in early life and is left untreated, it may result in amblyopia.
The Government Medical College, Thiruvananthapuram, also known as Trivandrum Medical College, is a public medical college in Thiruvananthapuram, Kerala, India. Founded in 1951, it was inaugurated by Prime Minister Jawaharlal Nehru and is Kerala's first ever Medical College.
Marshall B. Ketchum University is a private university focused on graduate programs in healthcare and located in Fullerton, California. MBKU expanded from the Southern California College of Optometry which was founded in 1904. The university was officially established as a multidisciplinary university with the addition of School of PA Studies in 2011 and College of Pharmacy in 2013. Along with Hope International University, the campus bookends the north and south sides of the Cal State Fullerton campus respectively.

The UCL Institute of Ophthalmology is an institute within the Faculty of Brain Sciences of University College London (UCL) and is based in London, United Kingdom. The institute conducts research and post-graduate teaching in the area of ophthalmology.
Sanduk Ruit is an ophthalmologist from Nepal who was involved to restore the sight of over 180,000 people across Africa and Asia using small-incision cataract surgery.
The Australian College of Optometry (ACO) is an Australian non-profit working to improve the eye health and well-being of various Australian communities. Established in 1940, the ACO's goal is to deliver public health optometry, vision research and professional education.
Raymond Mark Stein, MD, FRCSC, DABO, is a Canadian ophthalmologist. He practices refractive and cataract surgery. He is the medical director of the Bochner Eye Institute in Toronto, Ontario and Chief of Ophthalmology at the Scarborough General Hospital.
The Himalayan Cataract Project (HCP) was created in 1995 by Dr. Geoffrey Tabin and Dr. Sanduk Ruit with a goal of establishing a sustainable eye care infrastructure in the Himalaya. HCP empowers local doctors to provide ophthalmic care through skills-transfer and education. From its beginning, HCP responds to a pressing need for eye care in the Himalayan region. With programs in Nepal, Ethiopia, Ghana, Bhutan and India they have been able to restore sight to over 1.4 million people since 1995.
