Comprehensive Eye Exams
Thorough exam, accurate prescriptions & diagnoses
Your eyes are made up of more than two million working parts. Except for your brain, your eyes are the most complex organs you have. As well as testing for vision, routine eye exams are a recommended cornerstone for ensuring the good health of your eyes. They are critical in the detection and prevention of eye disease.
Using state-of-the-art technology, Dr. Brian O’Donnell’s thorough eye exams provide precision prescriptions and early detection or diagnosis of eye problems and disease. By diagnosing eye problems early on, Dr. O’Donnell can provide treatment options and in many cases restore or prevent vision loss.
How often should I get an eye exam?
Patients should be seen annually for an eye exam. At-risk patients, such as diabetics, should get annual or more frequent exams.
Accurate prescriptions and diagnosis through experienced care
Dr. O’Donnell has over two decades of experience performing complete eye examinations. When he does eye exams, he refuses to cut corners. Technology is rapidly changing the eye care industry and Dr. O’Donnell uses the latest in diagnostic equipment in his exams.
Visual Acuity testing
Dr. O’Donnell starts his exam with a Visual Acuity Test using the familiar chart of decreasing letter size, known as the Snellen chart.
What is 20/20 vision?
His visual acuity measurements evaluate how clearly each eye is seeing. The results of visual acuity testing are written as a fraction like 20/40. For example, if you have 20/20 vision, you can see clearly at 20 feet what should normally be seen at that distance. If you have 20/40 vision, it means that you can read at 20 feet of distance what a person with 20/20 vision could read from 40 feet away. In actual fact, 20/20 is only the average visual acuity and good vision is 20/15 or 20/10.
Setting your prescription—Automated Refractive Testing
Dr. O’Donnell next performs advanced automated refractive testing. This is the part of the eye exam that determines the power needed for the lens in your glasses or contact lenses to see your best. An autorefractor is used to get a starting point on your prescription and then a phoropter is used to determine the exact prescription.
Eye Health Examination
Dr. O’Donnell does a thorough review of your eyes’ health history and your medical history and conducts various tests of your eye’s health. These include a glaucoma check and a dilated exam to check your internal eye health. As needed, he uses various other diagnostic tools to test for your eye health.
In addition to eye diseases, dozens of general diseases – from high blood pressure to certain cancers – can show symptoms in your eyes, giving you a greater opportunity for early diagnosis and treatment.
What is a dilated exam?
In a dilated exam, special eye drops are placed in your eyes which cause the pupils to widen. Dr. O’Donnell uses special magnifying lens to examine your retina for signs of damage or disease such diabetic retinopathy or macular degeneration. Dr. O’Donnell considers that the only way to appropriately assess for significant retinal disease is through the use of a thorough dilated exam, although it is optional.
