At Precision Eyecare our eye examinations provide you with the highest standards of quality visual care and focus on your special needs and identified risk factors. A thorough eye examination consists of a variety of standard tests designed to measure visual acuity and other vision faculties, as well as observe the health of the eye and check for common eye diseases. There is no pain or discomfort associated with an exam, and they typically take less than an hour. A thorough evaluation is necessary to prescribe proper corrective lenses or contacts, but can also serve a more specialized purpose, such as determining eligibility for laser refractive surgery, or monitoring an eye condition.
 
 
  
 
 
  
  • Introductory Interview: The doctor will ask basic questions about a patient’s medical history and eye health history.
  • External Examination: The doctor inspects all outward visible parts of the eye and surrounding tissue.
  • Pupil Inspection: The patient’s pupils will be inspected for equal size and regular shape. Then the doctor tests how they react to light and objects at various distances.
  • Eye Muscle Health and Mobility: Eye movement is checked in six directions, as well as tracking a moving object.
  • Visual Field: The patient covers one eye at a time, and with the other eye gazing straight ahead, identifies objects in peripheral vision
  • Visual Acuity: A common means of measuring visual acuity is the Snellen chart. This is a large card or projection with progressively smaller horizontal lines of random block letters. The test determines how well a patient can discern detail at a given distance. Patients taking this test will cover one eye and then read aloud the letters of each row, starting from the top. The smallest row that can be accurately read indicates the patient’s visual acuity in that eye.
  • Refraction: This test is used to find the best corrected vision, if necessary for prescription eyewear or contacts. The doctor will try various lenses in front of each eye, as the patient focuses on a chart at a distance or up-close, to help determine the best power of correction.
  • Color Vision: The doctor shows the patient a series of images with symbols embedded in color dots or patterns. Based upon the patient’s ability to identify the symbols, certain types of colorblindness can be diagnosed or ruled out.
  • Ophthalmoscopy: This test is often done with an ophthalmoscope, a handheld instrument with light and magnifying lenses. Alternatively, the doctor may use other means, such as a slit lamp, which affords a more three-dimensional view. Ophthalmoscopy aims to inspect the retina and surrounding internal eye. This test can help diagnose problems with the retina or detachment of the retina, and monitor diseases like glaucoma and diabetes. An opacity in the eye can indicate a cataract. Sometimes the doctor will dilate the pupils with eye drops, to gain a wider view of the internal eye.
  • Tonometry: This test measures intraocular pressure, which can be a sign of glaucoma if pressure is abnormally high. Internal eye pressure is measured either with a puff of air at the cornea or brief direct contact with the cornea, to measure how easily it is pushed inward.
 
 
 
 
If you have an emergency, which needs attention after the office is closed, please call our Brookings office number: (541) 469-7775.

Eye injuries can occur at any time. Our office is equipped to handle most eye injuries. The primary instrument we use is a biomicroscope, sometimes referred to as a slit lamp. The biomicroscope has a high magnification and is particularly designed to aid us in evaluating the extent of an eye injury. Whether it is a laceration, foreign particle embedded or a burn, the biomicroscope is the primary tool to carefully examination the injury.
