What Does an Eye Doctor Do?

An eye doctor’s job is to detect diseases of the eyes. They can also help patients with a variety of other health problems.

According to NHIS and JCUSH, around 88 million adults see or talk to an eye care professional every year. In this article, we will take a look at the different types of eye professionals and their areas of expertise. For more information, click the link https://dryeyecenterofmd.com/ provided to proceed.

An optometrist is a healthcare professional who provides optical and medical eye care. They prescribe corrective lenses to help with refractive errors (e.g. myopia, hyperopia, presbyopia, astigmatism), manage amblyopia diagnosis and treatment, and assess ocular conditions associated with systemic diseases (such as diabetes and hypertension). They can also prescribe broad-spectrum topical antibiotics and some oral drugs including scheduled analgesics.

They can perform many ocular examinations, including binocular vision testing and fundus exam. They can also diagnose and treat ocular disorders, such as dry eyes, macular degeneration, glaucoma, cataracts, and diabetic retinopathy. They can also perform certain surgical procedures such as corneal transplants and lens replacement. They can also counsel patients on the pros and cons of surgical and non-surgical options to meet their occupational, avocation, and lifestyle needs.

Optometrists work in high street practices that may be independent or part of a national or international chain, as well as in hospitals and clinics where they are part of a large team of eye-specialists and healthcare science staff. They are often supervised by an ophthalmologist or specialist nurses.

A career as an optometrist requires high undergraduate grades, a good score on the Optometry Admission Test, and four years of professional education at a school of optometry. Graduates receive a Doctor of Optometry degree and are licensed to practice. Some optometrists choose to complete an extra year of study and become specialists in particular fields such as contact lenses or ocular oncology.

Each day, more than 16 million Americans struggle with undiagnosed or untreated vision impairments that a comprehensive eye exam could have prevented. America’s primary eye health and vision care providers – doctors of optometry, or O.D.s – are on the frontline of health care, and play an important role in helping people reach their full potential. They are the first line of defense against blindness and other eye and vision problems. They provide preventive, diagnostic and therapeutic care to all ages. They detect systemic diseases and their ocular manifestations, and provide vaccinations. They also conduct research in their field of expertise.


An optician is an eye care professional who is responsible for guiding patients in their purchases of frames, contact lenses and other eye wear. They must be familiar with all of the latest trends in eyewear and have extensive knowledge about all types of lens materials. Opticians usually work in a retail environment and are highly customer-oriented. They are responsible for a variety of duties, such as measuring the patient’s eyes, taking an order for eyeglasses, and fitting glasses to ensure that they fit properly. Opticians also have the responsibility of ensuring that patients are well-informed about their options in regards to lenses, frame materials and color choices.

During an eye exam, optometrists are trained to spot early signs of disease and other health issues in the eye. They recommend that adults receive an eye exam every one or two years. Some people may need to visit an eye doctor more often than this, depending on their age and other factors.

Medical eye exams are important for everyone, even those with healthy eyes. Optometrists can identify ocular diseases and conditions in their earliest stages, and many of these can be treated or managed with medications and other measures. An annual medical eye exam is also recommended for all children.

Aside from an ophthalmologist and an optometrist, there are other professionals who can help to improve a person’s vision. Nurses, medical assistants and technicians are all trained to assist an eye care practitioner with more complex tests or operations.

While there are three main types of eye care professionals, most people will visit all of these individuals during the course of their life. An ophthalmologist, an optometrist and an optician are all important to your eye care, but it is helpful to understand the difference between each one so you can determine which is right for your needs.

An ophthalmologist is a medical doctor who has completed extensive postgraduate education in the diagnosis and treatment of eye diseases and other health problems. They are licensed to perform surgery on the eye. An optometrist is a primary eye care provider who has completed extensive education in diagnosing and treating vision disorders. An optician is a skilled eye care professional who has completed a short program and is qualified to help patients select and fit eyeglasses and other visual aids.


Ophthalmologists are medical doctors who specialize in the eye. They can diagnose and treat medical conditions in the eyes as well as complete surgeries. They also work on research and innovative treatments. They are primary-level care providers and often work with optometrists to perform eye exams and surgery. They have completed a minimum of eight years of post-graduate medical school and have earned a Doctor of Medicine degree.

During the course of their education, these doctors learn about the anatomy and physiology of the eye. They also have extensive training in performing cataracts, cornea and glaucoma surgeries. They also have the ability to prescribe medications and other forms of treatment for common eye problems.

If your optometrist suspects a health condition that requires further testing or treatment, they may refer you to an ophthalmologist. If you have a severe eye problem such as uncontrolled diabetes or a retinal detachment, your ophthalmologist will probably recommend a surgical procedure.

Some ophthalmologists have additional training in specific areas of the eye, and they are known as subspecialists. They can perform complex procedures such as LASIK and refractive cataract surgery on patients with complicated needs.

They may also have a specialty in neuro-ophthalmology, and they can help treat issues relating to the brain and nerves. This includes the unequal pupil size referred to as nystagmus, which can occur due to trauma, certain diseases and brain injuries.

The three roles are distinct, but they all play a vital role in your eye and overall vision care. An ophthalmologist, an optometrist and an optician are part of the ultimate healthcare team that works together to keep you healthy and happy.

Make sure to schedule regular appointments with each type of healthcare professional to ensure you stay on top of your ocular and medical health. Prevention and early detection of ocular and other medical conditions are essential for your overall wellbeing. Make it a habit to get an annual medical eye exam as part of your general healthcare regimen. This will ensure you catch any potential eye issues in the earliest stages and prevent them from progressing into more serious diseases.

Glaucoma Specialist

A glaucoma specialist is an eye doctor who is trained to diagnose and treat glaucoma. She may recommend conservative treatments such as medication or eye drops, but if these don’t have the desired effect she will likely refer you for more aggressive treatment options. Glaucoma eye specialists use state-of-the-art diagnostic equipment including slit lamp ophthalmology and high-resolution optical coherence tomography (OCT).

In most cases, glaucoma is diagnosed by family physicians or optometrists, but if there are any symptoms or signs of the disease it is important to see a glaucoma specialist immediately. The reason is that this health professional can determine if you have the disease, how far along it is and your risk of blindness.

Once your ophthalmologist has determined that you have glaucoma, she will test your eyes for the disease by taking several different readings of your eye pressure, measuring the size of your pupil and testing your peripheral vision with visual field tests. Your eye specialist will also ask you about your medical history and family history of the disease. She will then dilate your eyes and take detailed measurements of the structure of your retina and optic nerve.

After a thorough examination, your ophthalmologist will give you a complete eye care regimen that may include prescription medications, eye drops and/or laser surgery. She will provide you with a schedule for follow-up visits. In many cases, a glaucoma diagnosis requires an ongoing commitment to follow the prescribed therapy.

If conservative treatments don’t work, your glaucoma specialist will likely recommend surgery. During laser glaucoma surgery, your ophthalmologist uses a beam of light to create a new pathway for fluid to escape your eye and reduce your intraocular pressure. In more advanced surgical techniques such as canaloplasty and viscocanalostomy, your doctor uses very thin tubes to open up the drainage channels of your eye.

These procedures are used to manage narrow-angle glaucoma and angle-closure glaucoma, which can be difficult to treat with medications. Weill Cornell Medicine ophthalmologists are expert in both of these procedures and have the specialized equipment needed to do them, such as our non-contact slit lamp Optical Coherence Tomography (OCT) units and our Artemis Very High Frequency ultrasound eye scanner.
