Comprehensive Eye Exams
Comprehensive eye exam in Plano and greater Dallas Area
Periodic eye and vision examinations are an important part of preventative health care. Many eye and vision problems have no obvious signs or symptoms. As a result, individuals are often unaware that problems exist. Early diagnosis and treatment of eye and vision issues are important for maintaining good vision and eye health, and when possible, preventing vision loss.
At Constant Eye Care, a comprehensive adult eye and vision examination may include, but is not limited to, the following 7 areas. Please note that individual patient signs and symptoms, along with the professional judgment of the doctor, may significantly influence the actual testing performed.
1. Patient Screening: Patients will have an Auto Refraction performed by one of our technicians. This device gives the doctor an objective measure of a person’s prescription. This is a starting point for the patient’s prescription. The Auto Refractor also takes a measurement of the curvature of the cornea, the clear outer surface of the eye. This measurement is particularly critical in determining the proper fit for contact lenses, especially fits with high astigmatism.
Hate the “Air Puff test”? No PROBLEM. Our office has invested in the I-Care Tonometer. This new technology allows us to get an estimate of your eye pressure without utilizing the air puff. Anyone with eye pressure greater than 22 mmHg is at an increased risk of developing glaucoma, although many people with lower pressures also develop glaucoma. This is only one test in the management of glaucoma. Throughout the exam the doctor will be evaluating your risk for developing glaucoma.
2. Patient history: The doctor will ask about any eye or vision problems you may be having and about your overall health. The doctor will also ask about any previous eye or health conditions of you and your family members.
3. Visual Acuity: Visual acuity measurements evaluate how clearly each eye is seeing. The results of visual acuity testing are written as a fraction such as 20/30. When testing distance vision, the top number in the fraction is the standard distance at which testing is done, twenty feet. The bottom number is the smallest letter size you were able to read. A person with 20/30 visual acuity would have to get within 20 feet of a letter that should be seen at 30 feet in order to see it clearly. Normal distance visual acuity is 20/20.
4. Preliminary Tests: May include evaluation of specific aspects of visual function and eye health such as depth perception, color vision, eye muscle movements, peripheral or side vision, and the way your pupils respond to light.
5. Refraction: Refraction is conducted to determine the appropriate lens power needed to see your best. Using an instrument called a Phoropter, your optometrist places a series of lenses in front of your eyes to refine the power that allows the clearest vision. In some cases, such as for patients who can’t respond verbally or younger kids who are shy, eye drops are used. The drops temporarily keep the eyes from changing focus while testing is done, and the doctor will utilized a more objective test.
6. Eye Health Evaluation: External examination of the eye includes evaluation of the cornea, lens, eyelids, conjunctiva and surrounding eye tissue using a machine called a Slit Lamp. Evaluation of the retina and posterior section of the eye may be done through a dilated pupil to provide a better view of the back of the eye.
7. Conclusion: At the completion of the examination, your doctor will assess, evaluate, and determine a diagnosis and develop a treatment plan. The doctor will discuss with you the nature of any visual or eye health problems found and explain available treatment options. In some cases, referral for consultation by another health care provider may be indicated.
