An overnight trial confirms success
This step is designed to assist the OOK specialist in confirming that the therapy will be successful for you.

The retainers are similiar to regular contact lenses in appearance and handling requirements, although of course they function differently. If you are new to contact lenses, you will be taught the proper handling and insertion of retainers. After scheduling you for a morning appointment, you will be sent home with the OOK lenses and instructed to insert the lenses before falling asleep.

After waking, you will wear your lenses into the office for evaluation of the fit. These diagnostics will not correct your vision, and you may need to arrange for transportation to the office that morning, particularly if you drive. The "on-eye" response to the retainer will confirm that overnight wear of contact lenses is safe for you. In addition, it provides diagnostic data for the OOK specialist in determining the next paramerters for the custom retainers.

Following microscopic evaluation, the lenses will be removed and you will again have topography performed. If the shape change to your cornea is idea after this initial treatment, the specialist will test your vision. However, if the shape change is not as required, a re-trial will be scheduled. This could mean a number of days in the same lenses, or new parameters selected for overnight wear.

Your OOK specialist must achieve a fitting accuracy of 1/1,000,000th of a meter or 1/1000th of a millimeter. The diagnostic lenses are designed to assist the practitioner in reaching this small tolerance of error. Should the initial trial fit result in shape changes other than the goal, re-trials are necessary to achieve the ideal response. If you are lucky, 1 diagnostic overnight trial will be all that the specialist will require. However, it is not uncommon to require numerous changes throughout the early stages of therapy.
