Eye Exams

eye exam

Dr. Cantrup offers a comprehensive eye examination that will uncover hidden, symptomless, potentially sight-threatening eye disorders and diseases that are not found by a simple vision screening.

An eye examination is a painless, routine and pleasant experience. The only way to accomplish a comprehensive eye exam is through a complete dilation of your eyes. By thoroughly examining the inside of your eyes in a dilated state we can detect early signs of glaucoma, cataracts, hypertension and even the onset of diabetes. This is why our routine vision examinations in our office require a total of approximately 30 minutes. This period of time is needed to perform all the tests necessary to thoroughly assess your eyes and visual efficiency.

Here is some advice for you during your eye examination:

Don’t worry about making a mistake or giving the wrong answer .
Don’t worry about your answers contradicting one another.
Don’t hesitate to say so if you are unable to answer some of the questions.
Don’t be alarmed if, for a few minutes during the examination, you find your vision getting worse instead of better.
Don’t be afraid to ask the doctor any questions that you may have.


What does an eye exam include?

Your Medical History – Since the eyes are a part of the body, they can be affected by seemingly unrelated health conditions. It is important for you to provide all information, regardless of how insignificant you might think it is. We must know about your general health and your medication including non-prescription medication prior to treatment. An optometrist obligated to protect all your medical history as confidential information under federal law, so be as open and forthright in providing your health information as you can.

Neurological Screening – Evaluating the way your eyes and pupils work together and individually can tell us if the nerves and muscles controlling your eyes are working properly or require more investigation.

The Refraction – Both automated and doctor-controlled instruments, plus the patient-directed methods, are used to obtain the best prescription for you.

Visual Fields Testing – Your ability to see to the side and above and below will be tested with computers, if and when necessary.

Eye Health Testing – This takes up most of the examination. The microscope is used, the pupils are dilated, and the inside of the eye is viewed using the proper instruments. Tests related to the following are all part of a complete examination:

  • Clearness of vision (Myopia, Hyperopia, Astigmatism)
  • Colour vision
  • Focusing ability (Presbyopia)
  • Eye muscle control
  • Lazy eye (Amblyopia)
  • Glaucoma
  • Cataracts

The Consultation – Following the examination, all patients, parents or guardians will get a careful explanation of their test results and the doctor will discuss recommendations regarding any needed preventive or remedial care. The doctor will gladly answer all of your questions regarding the exam and your results.
