Contact Lens Exams

Contact lenses are medical products regulated by the FDA. Just like medicine, contact lenses require a prescription and has an expiration date of one year from the date of your contact lens examination. This means that your eye doctor has to evaluate the health of your eyes and fit of your contacts every year in order to determine the optimal prescription for your eyes. Contact lens examinations are required on a yearly basis. These tests are done to make sure your eyes are healthy, that the lenses fit your eyes properly, and to ensure that you are seeing as clearly as possible. Content lens examinations are a separate service from a patient’s annual comprehensive eye exam. It can be easy for patients to overlook the technicalities, time, and evaluation involved when prescribing contacts.

Choosing the right contacts for you

For contact lens examination/fitting, a separate service fee is applied. These fees are determined by the type of lenses you are fit with:

 

    Soft Spherical
    Soft Toric
    Soft Multi-Focal
    RGP Spherical
    RGP Toric

In a contact lens examination, you may expect the following procedures:

Contact Lens Examination/Fitting
To begin, the front surface of your eye’s curvature is measured with an instrument called a keratometer. With the keratometer, your optometrist has a starting point for determining the proper curve and size for your contact lenses. With contact lenses that are too flat or too steep for the shape of your eyes, your contacts will feel very uncomfortable and/or can cause damage to your cornea. Your contact lens fitting may also include additional computerized measurements of your eyes that let your doctor see the curve of the entire front surface of your eyes. The keratometer measures only a small area of your eye at the apex of the cornea.

Tear Film/Corneal Health Analysis
Your personal contact lens fitting will include an evaluation of the tear film on the front of your eyes. The tear film is a smooth surface for light to pass through the eye, nourishes the front of the eye, and provides protection from injury and infection. Your optometrist will also carefully evaluate the health of the cornea with an instrument called a biomicroscope (also called a slit lamp). This is to ensure that there are no other problems that could make wearing contact lens a painful experience. It also gives your doctor a baseline from which he can monitor any changes to your eyes from wearing contact lens.

 

Next, trial lenses may be applied to your eyes and evaluated with the biomicroscope to judge the fit of the lenses and how much they move with each blink. This step is also done at each follow-up visit in the contact lens fitting process. Sometimes, lenses that appear to fit fine when first applied can tighten up after several hours of wear. Examining the fit of your lenses several times is essential to ensure your lenses continue to fit properly and cause no adverse effects to the cornea.

After you have consulted with your optometrist and know that your contact lenses fit you the way that it should, by providing vision and comfort, is when your final contact lens prescription will be written. The prescription includes contact lens power, contact lens base curve, and diameter.

Here at MPO Eyecare, we provide the following services to ensure you are getting the best contact lens care after your contact lens examination:

Follow Up Visits and Replacement Contact Lenses
After your contact lens exam/fitting is complete, we recommend a follow up visit to determine that the contacts meet your level of comfort and how well you see. Patients may find that one brand may have a more comfortable fit over another contact lens brand. For some patients, (more common for astigmatic patients) it may require a few follow up visits to ensure the right contact lens fits.
