Comprehensive Eye Exam


Please Note: A regular Eye Exam might not include all the steps a Comprehensive Eye Exam has. Please consult our optometrists for details of the eye exam.

 

 

STEP 1.
Auto-Refraction
An Auto-refraction is performed to obtain an approximate, objective measurement of a patients refractive error. This approximate value is further refined with a subjective refraction performed by the optometrist.

 

STEP 2.
Eye Focusing, Eye Teaming, and Eye Movement Testing
Assessment of accommodation, ocular motility and binocular vision determines how well the eyes focus, move and work together. In order to obtain a clear, single image of what is being viewed, the eyes must effectively change focus, move and work in unison. This testing will look for problems that keep your eyes from focusing effectively or make using both eyes together difficult.

 

STEP 3.
Slit Lamp Biomicroscopy
Slit Lamp Biomicroscopy is performed to examine the outer structures of the eye, such as the cornea. This is important to test for ocular inflammation and infections. Conditions, such as dry eye, can affect a patients vision and ability to wear contact lenses.

 

STEP 4.
Refraction
Refraction is conducted to determine the appropriate lens power needed to compensate for any refractive error (nearsightedness, farsightedness, or astigmatism). Using an instrument called a Phoropter, the optometrist places a series of lenses in front of your eyes and measures how they focus light using a hand held lighted instrument called a Retinoscope. The doctor may choose to use an automated instrument that automatically evaluates the focusing power of the eye. The power is then refined by patient's responses to determine the lenses that allow the clearest vision.

 

STEP 5.
Tonometry
Tonometry is the procedure Optometrists perform to determine the intraocular pressure (IOP), the fluid pressure inside the eye. It is an important test in the evaluation of patients at risk from glaucoma. Most tonometers are calibrated to measure pressure in millimeters of mercury (mmHg). Glaucoma will cause vision loss and does not present with symptoms until it is very advanced. Therefore regular eye checks are vital.

 

STEP 6.
Trial Frame Refraction
A trial frame is an adjustable spectacle frame that includes cells into which all the various lenses required to measure a patient’s Ametropia, Heterophoria and accommodation can be placed. A Trial Frame and Lens Set is an important aid to the Optometrist. A Trial Frame and Lenses can be used to determine the Patient's visual acuity before a new Rx is ordered, give the Patient a preliminary real-world experience of their new prescription, and assist the Patient in determining lens design, i.e., bifocal, trifocal or PAL.

 

STEP 7.
Diagnosis and Evaluation
At the completion of the examination, your optometrist will assess and evaluate the results of the testing to determine a diagnosis and develop a treatment plan. He or she 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 with, or treatment by, another optometrist or other health care provider may be indicated.
