The contact lens fitting involves special measurements of the curvature of the front surface of your eye with an instrument called a keratometer. This gives the Eye a starting point for determining the proper curve and size for your contact lenses. (There are many to choose from.) Contact lenses that are too flat or too steep for the shape of your eyes will be uncomfortable and/or can cause damage to the front surface of the eye, the cornea.
Many contact lens fittings include an evaluation (from the eye doctor) of the tear film on the front of your eyes. If your eyes are too dry, contact lenses may not be for you. If your eyes are marginally dry, some contact lenses work better than others. Typically, if your eyes are dry you should moisten them frequently with artificial tears. The doctor will also carefully evaluate the health of the cornea with an instrument called a slit lamp. This is to make sure there are no other problems that could make contact lens wear difficult for you. It also gives your doctor a baseline from which he can monitor any changes to your eyes from contact lens wear.
Next, trial lenses may be applied to your eyes and evaluated with the slit lamp 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 fitting process. Sometimes, lenses that appear to fit fine when first applied can tighten up after several hours of wear. Checking 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.
Finally, a review of how long to wear your lenses and how to care for them is an important part of the contact lens fitting. Simply, schedule an appointment to review your contact lens care.
