What is Done During an Eye Exam?
A routine eye exam is important for your overall health and well-being. If it’s been a while since you’ve visited your eye doctor, or you’ve never had an eye exam, it can be helpful to know what to expect when you visit the optometrist.
A comprehensive eye examination in Colorado Springs includes several steps. During this visit, Dr. Buckley uses various tests, tools and procedures to examine your vision as well as the health of your eye and recommend corrective lenses or further treatment if needed. A typical eye exam can take between 30 – 45 minutes depending on the health of your eyes, quality of your vision and if you need corrective lenses.
Most of your eye exam consists of various tests used to evaluate your vision. These include the following:
Tonometry – This test is important to determine your eye pressure in the evaluation for glaucoma. There are two main techniques used to test the intraocular pressure (IOP):
- Non-Contact Tonometry is typically performed by an eye technician (not Dr. Buckley). Many know this test as the one that blows a puff of air into the eye.
- Contact Tonometry is performed by Dr. Buckley by touching a probe to the eye. A numbing drop is used during this test, so you won’t feel a thing. For this reason, many patients prefer this method over the non-contact method.
Retinoscopy – This is a technique to obtain the objective measurement of your prescription. It provides a way to estimate what your vision prescription may be. It can either be performed by an automated machine or it can be done manually with a retinoscope. The retinoscope shines a bright light into the eye while Dr. Buckley observes the reflection off your retina determining your estimated prescription.
Refraction – This test uses a device called a phoropter to determine your corrective lens prescription. This instrument is used to test various lenses against your eyes, enabling Dr. Buckley to determine the best power prescription for your eyeglasses or contacts. The phoropter measures the exact level of astigmatism, myopia or hyperopia you may have.
Slit Lamp – The slit lamp exam allows the eye to be analyzed from front to back. During this test in Colorado Springs, Dr. Buckley uses a special high-power microscope to examine the structures of your eye, testing for infections or ocular diseases. This test is beneficial for detecting conjunctivitis and other common eye issues as well as more serious ocular conditions such as cataracts and macular degeneration.
Cover Test – During this test, Dr. Buckley will cover one eye at a time to assess any ocular deviation such as strabismus (also known as an eye turn or lazy eye). Essentially, this test measures how well your eyes work together and helps detect problems including poor depth perception.
Dilated Fundus Exam – This eye exam test requires an eye drop to be placed in the eyes to dilate the pupil. With the pupils dilated, it creates a larger window for Dr. Buckley to look inside the eyes. The drops typically take 15-20 minutes to take effect. Once dilated, Dr. Buckley will examine the eyes for various conditions. This is an important test for measuring the health of the internal structures of the eye.
Fundus Photography – Fundus photography is an advanced digital retinal photograph. By taking a digital image of the back portion of the eye (the retina), Dr. Buckley can detect and monitor your ocular health. The screening picture that is produced captures a clear view of the optic nerve, blood vessels, macula and fovea. Fundus photos can be a baseline measurement for future comparison.
If you are experiencing specific vision problems, additional tests and further examination may be required. Even if you are not experiencing vision problems, it is still a good idea to have your eyes examined regularly, ideally every year.
