What is Overnight Vision Correction (OVC)?
Is everyone a candidate for OVC and can any doctor perform it?
The answer to both questions is no. It does not work on every patient and needs to be performed in a very exact and meticulous manner. Dr. Jeffries has received special training and has the necessary diagnostic equipment, computer software and expertise to perform OVC.
The procedure works best on mild to moderate amounts of nearsightedness or astigmatism. More severe cases can have their vision improved, but will still need some vision correction. The procedure also does not work well on certain shaped corneas. Also, there are several unmeasurable factors for each patient – most notably the cornea’s rigidity. Thus the speed of OVC varies with each patient. Generally, but not always, less nearsighted patients respond faster than more nearsighted ones. There are no age barriers for OVC. It is safe for children and adults and is an excellent alternative for children who are just first becoming nearsighted as studies have shown that OVC may prevent any further nearsightedness from occurring! Also, while success rates are very high, success cannot be guaranteed due to factors like the inability to wear the vision retainer for physiological reasons or other systemic health problems that may reduce wearing time.
Can you explain the OVC Program and what to expect?
A comprehensive eye health examination is performed first. Then, a corneal topographer is used to obtain a very precise computerized “map” of the cornea’s shape. This information is placed into the OVC computer software and a diagnostic retainer is fit in the office. If at that time it is determined that you are a good candidate for OVC, your own vision retainers will be ordered. It takes about one week for the retainers to be made and delivered.
When you pick up your retainers, you will be instructed on how to use and care for them. The maintenance is very easy and involves only one bottle of solution. If the retainers fit properly, you may wear them that first night. Your should see well with the retainers on.
We will see the first morning after you wear your retainers. You should come to the office wearing your vision retainers. We will remove them for you. Of course, should you experience any problems while at home with your retainers, simply remove them. And yes, we will show you how!
Most of the visual changes occur rapidly over the first few days. As the cornea changes shape and vision improves, we will refit and reorder successive vision retainers (if needed). During this interim period we will supply you with (no-charge) soft disposable contact lenses to be worn during the day. These are usually only needed for the first few days. For most patients, only one pair of retainers is needed.
The majority of patients achieve excellent vision in only a few days – many after only one night of wear. Even after you are seeing well, we will continue to see you a while longer to ensure your cornea is adapting to the retainers. Most patients are done with their follow up care in about one month although some may take more or less time. When the treatment is completed, the last retainer used will be worn on a nightly basis. Some patients are able to use the retainers every other night.
Is OVC new?
Attempts to re-shape the cornea have been tried since contact lenses were first fit. The process used to be called orthokeratology. This process would often take over a year to complete and the results were not nearly as favorable as our OVC program. For this reason, many doctors and patients elected not to participate in orthokeratology. With the newer diagnostic technology used to measure the corneal shape and the newer materials being used for vision retainers, OVC is now a viable alternative for many nearsighted or astigmatism patients.

What is the cost of the OVC Program?
What happens if I stop wearing the OVC retainers?
Should you stop wearing your retainers, your vision will slowly return to its original state. While the degree of success is very high, it cannot be guaranteed. However, when the corneal topography and computer software indicate a patient will be successful, your chances of success are excellent. It is our policy to not perform OVC on patients that we do not thing will have an adequate outcome. But remember, OVC is completely reversible, unlike surgical options to correct your vision. Rates and amount of improvement vary from one person to the next.
