What is Ophthalmology?

Ophthalmology is a medical and surgical specialty that focuses on the diagnosis and treatment of eye disorders. A physician who specializes in ophthalmology is known as an ophthalmologist. A bachelor's degree in medicine is required, followed by four to five years of ophthalmology residency training to become an ophthalmologist. Ophthalmology residency programs may include a one-year internship that includes training in internal medicine, pediatrics, or general surgery.

Additional specialised training (or fellowship) in a specific field of eye pathology may be sought. Ophthalmologists are licensed to administer drugs, use laser therapy, and perform surgery to treat eye diseases. Academic research on the diagnosis and treatment of eye conditions can be performed by ophthalmologists.

Types of Ophthalmology Subspecialist 

Comprehensive ophthalmology decides that he has to visit a subspecialist to treat the condition that he or she is suffering from. The following are some of the subspecialists.


The cornea is the transparent, dome-shaped covering that covers the iris and pupil in front of the eye. Corneal eye disorder, such as Fuchs' dystrophy and keratoconus, is diagnosed and managed by a cornea subspecialist. Many cornea subspecialists often perform corneal transplants and refractive surgery (such as LASIK). They also deal with corneal damage and difficult contact lens fittings.


The light-sensitive tissue covering the back of the eye is known as the retina. The macula is a tiny region of the retina that is responsible for your detailed vision in the middle. Retinal disorders, such as macular degeneration and diabetic eye disease, are diagnosed and treated by an ophthalmology retina specialist. They treat issues with the vitreous, the gel-like fluid in the centre of the eyeball, as well as broken and detached retinas.


The optic nerve, which links the eye to the brain, is affected by glaucoma. When the fluid inside the eye isn't circulated properly, pressure builds up inside the eye, causing damage to the optic nerve. Glaucoma subspecialists treat eye pressure with medicine, lasers, and surgery.

Pediatric Ophthalmology

Ophthalmologists for children and babies are known as pediatric ophthalmologists. Pediatric eye doctors diagnose and treat eye misalignment, uncorrected refractive errors, and variations of vision between the two eyes, as well as childhood eye disorders and other conditions. Adults with eyes that do not fit together properly are often treated by strabismus specialists.

Oculoplastics Ophthalmology

Any harm or complications with the eyelids, bones, and other structures around the eyeball, and the tear drainage system are repaired by oculoplastic surgeons. They use surgical injections to enhance the appearance and function of facial structures around the eyes and face.


Neuro ophthalmology treats vision disorders involving the interaction of the eyes with the brain, nerves, and muscles. Optic nerve defects, different forms of vision loss, double vision, irregular eye movements, uneven pupil size, and eyelid irregularities are among the disorders they diagnose and treat. Strokes, brain tumours, multiple sclerosis, and thyroid eye disease are all diseases that can cause these issues.

What Does an Ophthalmologist Do?

  • Ophthalmologists are qualified to offer comprehensive eye care, ranging from the prescription of glasses and contact lenses to complicated and delicate eye surgery.

  • Ophthalmologists diagnose and manage eye disorders, administer drugs, and perform a variety of surgeries to enhance or avoid the progression of the eye and vision-related problems.

  • Many ophthalmologists are now interested in clinical studies into the causes of eye disorders and vision issues, as well as potential solutions.


A partial list of the most common diseases treated by ophthalmologists include:

  • Cataract

  • Excessive tearing (tear duct obstruction)

  • Proptosis (bulged eyes)

  • Eye tumours

  • Diabetic retinopathy

  • Dry eye syndrome

  • Glaucoma

  • Macular degeneration

  • Refractive errors

  • Strabismus (misalignment or deviation of eyes)

  • Uveitis

How is an Ophthalmologist Educated and Trained?

  • All ophthalmologists complete a minimum of three years of residency (hospital-based training) in ophthalmology after four years of medical school and one year of internship.

  • Ophthalmologists undergo advanced training in all facets of eye care during residency, including eye disease prevention, diagnosis, and medical and surgical treatment.

  • A subspecialty, or a specialised field of eye care, such as glaucoma or pediatric ophthalmology, also requires an additional one to two years of training.

  • To keep updated on the latest quality of treatment, all ophthalmologists must complete continuing education requirements.

Advances By the Opticians 

Ernst Abbe (1840–1905), a co-owner of the Zeiss Jena factories in Germany, where he invented various optical instruments, was a prominent optician in the late nineteenth and early twentieth centuries. Hermann von Helmholtz (1821-1894), a polymath who contributed to many fields of science and invented the ophthalmoscope in 1851, was a polymath who made contributions to many fields of science. They had both studied the optics of the eye and performed theoretical calculations on image creation in optical systems.

Interesting Facts About the Ophthalmology 

  1. Marshall M. Parks was the "father of pediatric ophthalmology.

  2. Ophthalmologists estimate that ophthalmic surgery accounts for around 30% of their practice on average.

  3. Around 71 percent of ophthalmologists work in community practice, and each sees nearly 131 patients per week on average.

  4. In a typical week, ophthalmologists write about 68 prescriptions.

  5. According to the majority of ophthalmologists, the average age of their patients is between 50 and 69 years old.

  6. Capsulotomies - Laser is the most common procedure conducted by an ophthalmologist in a typical month. They do about 7 of these a month on average.

  7. Ophthalmologists prescribe, recommend or administer about 35 artificial tear preparation products in an average week and 32 lubricants.

  8. Optho Life Sciences fosters is a unique network in the pharma industry that produces medicines to relate eye problems for four-plus decades.

FAQs on Ophthalmology

1. What is the Difference Between Optometrists Vs Ophthalmology Vs Opticians?

Answer. Optometrists, ophthalmologists, and opticians are all eye care professionals of varying levels of experience, specialization, and practise scope. Optometrists are eye care professionals who may observe, diagnose, and treat eye problems medically. Ophthalmologists are eye surgeons who specialize in procedures involving the eyes and performing ophthalmic surgery. Opticians operate in vision treatment centers and optometry departments like customer service professionals.

2. What is Ophthalmology Treatment?

Answer. Ophthalmology is a branch of medicine that focuses on the diagnosis, treatment, and prevention of eye and visual system diseases. A variety of clinical conditions can affect the eye, its surrounding structures, and the visual system.

3. What Diseases Does an Ophthalmologist Treat?

Answer. Some of the diseases which ophthalmologists treat are amblyopia (lazy eye), astigmatism, cataracts, corneal disease, diabetic retinopathy, dry eye, eye disease simulations.

4. What are the Most Common Eye Disorders?

Answer. Some of the most common eye problems are refractive errors, refractive errors, including nearsightedness, farsightedness, and astigmatism, age-related macular degeneration, cataracts, diabetic retinopathy, and glaucoma.
