Background

Our eyes are our guides to the world. They capture color, movement, and light so that we can experience our life with details. However, when something goes wrong with our vision, it takes a specific kind of doctor to help us see clearly again. That type of doctor is an ophthalmologist. 


Ophthalmology refers to the branch of medicine that focuses on the eyes and the visual system in order to deal with and prevent blindness and restore sight from prescribing glasses to performing delicate eye surgeries, ophthalmologists protect one of our most precious senses. It is a field that requires precision and compassion as even one of the smallest movements can change how a person sees the world.

So, what do they do?

Ophthalmologists are physicians who specialize in diagnosing and treating diseases of the eye and the rest of the vision system. Unlike optometrists (doctors who provide vision exams and corrective lenses), ophthalmologists are medical doctors capable of performing surgeries for complex eye diseases. 


Some of their common responsibilities include:

  • Performing eye exams

  • Diagnosing conditions such as glaucoma, cataracts, and macular degeneration

  • Treating infections and injuries of the eye

  • Performing laser or surgical procedures to correct vision or repair damage

  • Prescribing eyeglasses, contact lenses, and medications

  • Managing systemic diseases that affect the eyes, such as diabetes or high blood pressure.

Additional Information

Some ophthalmologists may also focus on subspecialties such as pediatric ophthalmology (for children’s vision), neuro-ophthalmology (how the eyes and brain work together), or retina surgery (repairing the light sensitive tissue at the back of the eye).


Ophthalmologists use tools like slit lamps, optical coherence tomography scanners, and retinal cameras to visualize the structures inside the eye in microscopic detail. They may also use lasers to treat conditions or to reshape the cornea.

Required education and training

Becoming an ophthalmologist requires an individual to earn their bachelor's degree and to complete medical school. After that, they must enter a one-year internship program that is followed by a three-year residency in ophthalmology. During their residency, they learn to diagnose and manage a wide range of eye diseases, perform surgeries, and interpret images. Some may even go on to pursue fellowships in subspecialties like cornea and refractive surgery.

Importance

Vision is one of our most important senses and helps us with nearly everything we do: reading, driving, learning, visualizing others, and much more. When we lose our sight, we also lose an important part of us. Losing sight changes our world forever. As a result, Ophthalmologists are so important as they help us by preventing vision loss and treating diseases early through surgery and technology.

Background When most people think about surgery, they usually think about surgeons standing over their bodies and performing various procedures in order to save someone. Now although that is true, there’s a hidden figure behind every successful surgery that most people tend to overlook: the anesthesiologist. Anesthesiologists are responsible for managing pain levels, monitoring patients' vital signs, and making sure that their patients not only remain safe, but also stable throughout their surgery. Without these professionals, mortality rates would increase and the surgical process that we have today wouldn’t exist at all. So, what do they do? Anesthesiologists are docto...

Background One of the most demanding and precision requiring medical specialties is neurosurgery. Neurosurgeons are doctors who operate on the brain, spinal cord, and the nervous system. They perform some of the most complex and precise procedures in all of the medical field. Whether they are removing brain tumors, repairing spinal injuries, or stopping seizures, neurosurgeons are one of the most important types of doctors. As neurosurgery isn’t just simply cutting and stitching within the body, it is about navigating and working with the body's most important and delicate system: the nervous system. The system controls an individual's every thought, movement, and he...

Background Every time we drink a glass of water or some other liquid, our bodies rely on a complex system of organs in order to filter out waste, produce urine, and maintain our internal balance. However, when this system fails, it requires a special type of doctor in order to restore it. That doctor is a urologist. Urology is the branch of medicine that focuses on the urinary tract in both men and women, and the male reproductive system. It is a specialty that combines surgery and internal medicine. This allows urologists to treat a wide range of conditions from kidney stones and bladder infections to prostate cancer. So, what do they do? Urologists are physicians who are tr...
