Comprehensive Eye Exam in Las Vegas, NV

Annual comprehensive eye exams are an important part of eye care for people of all ages, including babies, children, adults, and seniors. If you need a prescription for eyeglasses or contact lenses, then you need regular eye exams to assess your vision so that your prescription can be updated if necessary.

A comprehensive eye exam, though, is about much more than your prescription for eyeglasses or contact lenses. Even if you feel your vision is fine, many eye diseases have little to no symptoms in the early stages, and the only way to identify them early on is through a comprehensive eye exam in Las Vegas.

What to Expect at a Comprehensive Eye Exam

Vision exams in Las Vegas, NV, with Dr. Ellen Merkin include a variety of vision and eye health tests to help her gain a full understanding of your eye health. Tests also provide insight as to any necessary care or treatment plans required. During a comprehensive eye exam, Dr. Merkin will test for basic vision problems to determine whether vision correction is needed. She will also look for early signs of eye diseases such as glaucoma, diabetic retinopathy, macular degeneration, cataracts, dry eye, and more.

We utilize the latest technology during a comprehensive eye exam, including the Optomap retinal exam. At the conclusion of your eye exam, Dr. Merkin will be able to diagnose any eye problems and develop a treatment plan or management plan tailored to your unique vision issues.

Patient History

Dr. Ellen Merkin will talk to you about vision or eye health problems you may be having, your overall health, medications you’re currently taking, and any work-related or environmental situations which could affect your vision and eye health. She will also ask you whether there’s a history of eye diseases in your family, as some eye diseases have a genetic component.

Visual Acuity

Your visual acuity, which is your clarity or sharpness of vision, will be measured at 20 feet using the Snellen chart.


The refraction test determines if you have any refractive errors, such as nearsightedness, farsightedness, and astigmatism, and determines the lens power needed to correct the error.

Eye Focusing, Teaming, and Alignment Testing

The eyes must be able to change focus and work well as a team for you to experience clear vision. Dr. Merkin will assess your binocular vision and ocular motility to determine if your eyes are working together as a team. This testing can identify problems that may be preventing your eyes from effectively focusing or which make using both eyes together more difficult.

Annual Comprehensive Eye Health Evaluation

During your exam, Dr. Merkin will use a microscope and other devices to assess your eye health and may dilate your pupils so that she can see internal eye structures. She will be able to check your eye pressure and can also identify eye and systemic diseases of which you may not be aware. At the conclusion of your eye exam, she will provide you with a prescription for eyeglasses or contact lenses if you need them to see your best. She will also talk to you about any vision or eye health issues revealed through the comprehensive eye exam.


In addition to these standard tests, Dr. Merkin may also perform additional tests if needed, such as checking for color blindness or assessing your retina and peripheral vision. She may also use specialized instruments, such as a slit lamp, to examine the front and back of your eye in greater detail.

After your exam, she will discuss the results with you and make any recommendations for treatment or follow-up care. This may include prescribing glasses or contacts, referring you to a specialist, or suggesting lifestyle changes to help improve your eye health.

It is generally recommended that adults have a routine complete eye exam every 1-2 years, depending on their age, health, and other factors. People who are at a higher risk of eye problems, such as people with diabetes or a family history of eye disease, may need to have more frequent eye exams.

Don’t wait; schedule your routine eye exam today and protect your vision for the future. Whether you’re experiencing symptoms or just want to maintain your eye health, our experienced eye doctor is here to help.

Can I do an eye exam online?

What is included in an eye exam?

An eye exam includes evaluating the health of your eye, including the retina, cornea, and lid margins. Dr. Ellen Merkin will measure your visual acuity and conduct a refraction to update your current eyeglass prescription. She will also do a visual field test to assess your peripheral vision and will screen for glaucoma.

What diseases can be detected in an eye exam?

An eye exam can detect early warning signs of many diseases and conditions, including diabetes, hypertension, cholesterol problems, and pituitary tumors.

How often do I need an eye exam?

We suggest scheduling a comprehensive eye exam at least once a year. Diabetic patients should have their eye health checked every 6 months.

Is it necessary for the doctor to dilate my pupils during the exam?

Dr. Ellen Merkin does not dilate patients at every appointment. Dilation allows a better view of the peripheral retina in order to look for abnormalities. Whether or not you need dilation during your eye exam will depend on factors such as your age and risk for eye diseases.
